Struggling to Recruit for Production Roles? What the Vacancy Actually Costs — and the Alternative Worth Pricing

Recruiting for production roles has become materially harder over the past few years, and the difficulty is not evenly distributed. It falls hardest on the roles that are physically demanding, and on sites away from large population centres.

This article looks at what the difficulty actually costs, and at an option that is often not considered because it sits under a capital budget rather than a recruitment one.

Why the labour pool has changed

Three things have happened at once.

The first is a change in migration patterns. Following the UK’s departure from the EU, freedom of movement ended and the immigration system moved to a points-based model with salary and skill thresholds that most entry-level production roles do not meet. The pool of candidates that many manufacturers had drawn on for years is therefore no longer available in the same way.

The second is geography. Manufacturing sites are frequently located on industrial estates outside towns, or in rural areas where land was available. Where public transport is limited, the practical catchment for a shift-work role is restricted to people who can drive and are willing to commute, which in some regions is a small pool competing with warehousing, logistics and retail employers who are recruiting from the same one.

The third is that the work itself competes poorly. A role involving repeated lifting for a full shift is harder to fill than a comparably paid role that does not, and it is harder to retain people in once filled.

The result is familiar: vacancies that stay open, reliance on agency cover at premium rates, and turnover concentrated in the same handful of positions.

What a production role actually costs

Recruitment difficulty is normally discussed in terms of time and frustration rather than money, which makes it hard to compare against any alternative. The figure below is the one to put alongside a capital cost.

Salary is not the cost of a role. The full cost of one operator, on one shift, works out approximately as follows:

Cost element

Basis

Annual cost

Gross salary

One full-time operator on approximately the National Living Wage

£26,437

Employer National Insurance

15% on earnings above the £5,000 secondary threshold

£3,216

Holiday cover

One month of cover per person per year, at the same cost

£2,471

Pension, sick pay, recruitment, HR administration, training, bonuses and management time

Add 20%, or agency fees where agency staff are used

£6,425

Total cost of one operator, one shift

 

£38,549

Round figures: approaching £40,000 a year for a single operator on a single shift. Manufacturers we work with consistently report all-in costs at or around that level, and higher where agency staff are used or where shift premiums apply.

Two adjustments are worth making for your own site. Smaller employers may be able to offset part of the National Insurance cost through the Employment Allowance. Night and weekend working normally attracts a premium, so a 24/7 operation’s per-head cost is higher than the figure above rather than simply a multiple of it.

The comparison that is rarely made

A standardised prebuilt robotic palletiser is openly priced from £57,900 + VAT. Set against the figure above, that is less than eighteen months of a single operator on a single shift.

The comparison scales with the shift pattern, and this is where it becomes decisive. A role that is covered around the clock is not one salary; it is four.

Shift pattern

Annual cost of the role

Payback on £57,900

One shift

£38,549

Approximately 18 months

Two shifts

£77,098

Approximately 9 months

Three shifts

£115,647

Approximately 6 months

24/7, four shift teams

£154,196 or more

Under 5 months

These figures count labour cost alone. They exclude the production increase that usually accompanies automation, the reduction in transit damage from consistent pallet quality, and the manual handling exposure that disappears when the lifting stops. Counting those normally shortens the payback further.

What this does and does not change

It does not mean replacing your workforce. In practice the people currently stacking pallets are redeployed to work that is easier to recruit for and easier to keep people in — line supervision, quality, changeover and covering multiple lines rather than one position.

What it removes is the vacancy. The role that is persistently hard to fill stops needing to be filled, and the recruitment effort can go into positions where a person is genuinely the right answer.

It also removes the variability. A palletising cell runs at the same rate in the eighth hour as in the first, does not take breaks, and is unaffected by an absence at short notice.

Whether it applies to your site

The case is strongest where several of the following are true:

  • One or more end-of-line roles are persistently vacant or covered by agency staff
  • The site operates more than one shift
  • The work involves repeated lifting for the length of a shift
  • The site is not close to a large labour market
  • Turnover in the role is high, so training cost recurs

Palletising is usually where this is examined first, because it is the heaviest repetitive manual task on most lines and the least disruptive place to automate — the cell sits at the end of the process rather than within it. The reasoning is set out in what to automate first, and the manual handling case in manual handling risks in palletising.

Working out the figure for your own line

The numbers above are illustrative. The ones that matter are yours, and they depend on your shift pattern, your current cover arrangements and your line rate.

We provide payback, ROI, OEE and intangible-benefits calculators and will work through them with you, so the case can be put internally with real figures rather than industry averages. Leasing and hire options are included with every quote; in most cases the savings exceed the lease payments from the point of installation.

What Should a UK Manufacturer Automate First? Why End-of-Line Palletising Is the Best Place to Start

Most manufacturers we speak to have already decided they need to automate. What they don’t know is where to begin.

The answer is usually the end of the line. Not because palletising is glamorous, but because it is the one place where a first project is low-risk, easy to measure, and almost always solving a problem that already exists.

Where UK manufacturing actually stands

The gap is real. According to the International Federation of Robotics, Western European manufacturers reached a record 267 robots per 10,000 employees in 2024. In the UK, industrial robot installations fell 35% to 2,500 units in the same year, placing the country 19th worldwide.

Meanwhile the pressures haven’t gone anywhere. Labour is harder to find and more expensive. Manual handling claims are expensive and avoidable. Customers want shorter runs and more variety, which makes changeovers the enemy.

Automation is the obvious answer. The question is which project to do first.

Why the end of the line is the right first project

It is the heaviest manual work you have. Palletising handles the product at its final weight, after everything upstream has handled it light — and every unit the line makes passes through that one point. Repeated lifting is where the injuries, the absence and the claims sit, and it is also the hardest job on site to recruit for and keep staffed. Under the Manual Handling Operations Regulations 1992, hazardous manual handling has to be avoided where reasonably practicable, and an affordable engineering control now exists for this one. We’ve set out the hazards, the duties and the options in a separate article: Manual Handling Risks in Palletising.

It is self-contained. A palletiser sits at the end. It doesn’t require you to rebuild your process, change your recipes or retrain the whole factory. If you were going to try automation somewhere, this is the least disruptive place to try it.

It is easy to measure. Cases per hour, pallets per shift, downtime, stack quality. The numbers are obvious before and after, which makes the second project far easier to get approved.

It gives you data you didn’t have. A modern palletising cell logs production and downtime and reports on it. For a lot of sites, that end-of-line log is the first honest picture they’ve had of where the line actually stops.

What “smart factory” really means here

The Industry 4.0 language — connected plant, live data, systems talking to each other — is not wrong. It is just usually sold backwards, as a platform to buy before there’s anything to connect.

In practice it starts with one machine that produces reliable data. A palletising cell can log throughput and downtime, generate OEE reports, and connect to stock or data systems where that is useful. The fault logger shows where the bottlenecks really are. That is a far more useful first step than a dashboard with nothing behind it.

Three things to get right, so the first project isn’t the last

Plenty of manufacturers have automated once, had a poor experience, and stopped. It is nearly always one of these three.

1. Who can programme it

This is the one that quietly decides whether the system gets used properly. If every new product size needs a robot programmer, the machine becomes a constraint rather than a benefit.

On a Granta system, an operator enters four numbers — length, width, height and weight. The software generates the stack patterns and the work behind them: robot paths, clearances, safety zones, speed profiles, and the turning and grouping of product on the conveyors, including for row gripping. Switching between products already on the system takes seconds. A brand-new size takes about five minutes. Operator-level programming combined with automated row gripping is patented to Granta.

2. Whether it survives a change of plan

Your factory in five years will not be your factory today. Lines move, products change, volumes grow.

Most palletising cells are built bespoke and fixed. We offer a modular system— a standardised platform that comes up on four floor bolts and can be rearranged, extended or relocated. The point is not that it’s modular. The point is that the capital you spend now survives a change of mind later.

3. Whether it fits the space you actually have

Space is the reason many good projects stall. Low ceilings, mezzanines, pedestrian zones, food areas and sites going forklift-free all rule out a conventional cell.

Our compact palletiser takes the finished pallet off at floor level with a pallet truck, and still feeds empty pallets automatically at speed — a combination rarely available elsewhere.

The natural second step: moving the pallet

Once the pallet is built, something has to move it. On most sites that is a forklift making the same short journey dozens of times a day.

AMRs and AGVs take that journey over — from palletiser to wrapper, wrapper to dispatch — and pair with any palletising cell. It is the obvious next project once the first one has proved itself, and it is where forklift-free sites end up.

What a first project actually costs

Our standardised prebuilt palletiser is priced from £57,900 + VAT. Other systems are quoted to your line. Leasing is included with every quote, with savings that usually exceed the payments from the start, and payback across our installs is often under a year once labour, throughput and manual-handling costs are counted.

We’ll give you the numbers for your own line rather than an industry average.

The Granta Cobot Palletiser: How It Is Specified, and Why We Believe It Leads the Market

A cobot palletiser uses a collaborative robot rather than a conventional industrial one. The distinction is that a collaborative robot has force sensing built in, which allows it to work in a shared space with people under an appropriate safety assessment.

Cobot palletisers are now widely available, and the specifications look broadly similar on paper. In practice they differ in five areas that determine whether the system performs on a real production line: payload, duty rating, how safety is configured, how the system is programmed, and what it costs.

This article sets out how the Granta cobot palletiser is specified in each of those areas, and why we consider it the strongest cobot palletising system available.

1. Payload: 30 kg

The Granta cobot palletiser uses a 30 kg payload collaborative robot. This is at the upper end of the collaborative robot class.

Payload is not simply case weight. The gripper, its mounting and any vacuum or pneumatic assembly all count against the figure, and on a palletising cell the gripper is a significant proportion of it. A cobot rated at 10 or 16 kg has considerably less capacity available for product than the headline number suggests.

A 30 kg rating means realistic case weights can be handled with a substantial gripper fitted, and multi-pick remains possible. It also means the robot is not operating continuously at the limit of its rating, which affects service life.

2. Duty: industrial grade, specified for continuous running

Many collaborative robots are lightweight units originally designed for assembly and machine tending, where the duty cycle is intermittent. Palletising is not intermittent. The same motion is repeated for the length of every shift, indefinitely and typically with higher payloads.

The robot used in the Granta cobot palletiser is an industrial-grade collaborative robot specified for 24/7 operation. It is built for the duty cycle palletising actually imposes, rather than adapted to it.

It also uses dedicated force sensing. This is worth distinguishing from the approach used by many lightweight cobots, which infer contact from motor current or torque. Dedicated sensing detects unexpected force directly and stops the robot, which is held until the safety is reset.

3. Safety: three configurations, and speed retained

The most common misconception about cobot palletisers is that a collaborative robot means no guarding, and that this is the whole benefit. In practice, running permanently in collaborative mode means running permanently at collaborative speed, which safety standards limit to around 2-3 pick and place cycles per minute due to the maximum movement speed allowed.

The Granta cobot palletiser is offered in three configurations, and the choice is made against the layout of the floor rather than a default:

ConfigurationHow it operatesBest suited to
No guarding, light curtains or scannersRuns in collaborative mode at all times, at collaborative speedLower-speed applications where the smallest possible footprint matters
Guarding with a light curtain at the entry pointRuns at full industrial speed. Slows to collaborative speed when the light curtain is broken, and continues runningHigher-speed applications where an operator enters mainly for pallet changeover
Safety area scanners around the cellRuns at full industrial speed. Slows to collaborative speed when the scanners detect movement in the safety zone, and continues runningCells with frequent or unpredictable pedestrian movement nearby

The point of the second and third configurations is that the system does not stop when someone approaches. It changes speed and keeps running, then returns to full speed once the zone is confirmed clear. Throughput is preserved during pallet changes and routine floor movement, which is where a stop-and-reset arrangement loses most of its output.

Many cobot palletisers are supplied in a single mode. Being able to select between all three, and to combine full-speed industrial running with collaborative operation when someone is present, is the practical difference in a working environment.

4. Programming: four dimensions, no robot programmer

Cobots are generally described as easy to programme, and by comparison with conventional robots they are. The comparison that matters, however, is against how a palletiser actually needs to be set up.

Most systems provide a drag-and-drop layer editor. The operator places each product on screen to build a layer, then rotates and duplicates it. The operator supplies the pattern; the software records it. The robot paths, clearances, safety zones, speed profiles and the orientation and grouping of product on the infeed are configured separately, and all of them change when the product size changes.

Granta’s software works in the opposite direction. The operator enters four dimensions — length, width, height and weight — and the software generates the viable stack patterns, ranks them by pallet efficiency, and derives everything downstream of the pattern, including the conveyor orientation and grouping required for row gripping. A new product size takes approximately five minutes and requires no robot-programming skill. Switching between sizes already held on the system takes seconds.

The same software is fitted to every Granta palletiser, so a cobot system is not a reduced-capability version of the range. The detail of how it differs from a pattern wizard is set out in Easy Palletiser Programming.

5. Cost: a premium specification without a premium price

A higher specification usually carries a higher price. In this case it does not, and the reason is production method rather than discounting.

Granta does not build cobot palletisers individually to order. They are built in batches, to a standardised design, and robots are purchased in batches of 25. Design time is spread across a production run instead of being charged to a single project, component costs fall with volume, and each system is assembled and tested to an established procedure rather than engineered from the beginning.

Volume is what makes that possible. Granta has one of the largest palletiser install bases in the UK and Ireland, and is among the largest installers of cobot palletisers in the country.

The result is that the Granta cobot palletiser is among the more competitively priced cobot palletising systems available, while using a 30 kg industrial-grade collaborative robot, three safety configurations and patented programming software. Leasing and hire options are included with every quote, and payback across our installations is frequently under a year once labour, throughput and manual handling costs are accounted for.

We will provide the figures for your own line rather than an industry average.

Specification summary

  • 30 kg payload collaborative robot
  • Industrial grade, specified for 24/7 operation, with dedicated force sensing
  • Three safety configurations: unguarded, guarded with light curtain, or area scanner
  • Throughput of 20+ products per minute, with row gripping available
  • Single or double infeed, with conveyors orientated to suit the layout
  • Single or double pallet positions, with pallet-truck take-off available
  • Gripper options including vacuum, paddle and vacuum bag grippers
  • Handles boxes, cases, packs, bags and sacks
  • Patented easy programming software as standard
  • Full CE and UKCA marking, with a technical file prepared for every project
  • Typical lead time of two to four months but can be a lot faster if required
  • Built in batches to a standardised design, which keeps the price competitive

Where a cobot is the right choice — and where it is not

A cobot palletiser is the appropriate specification where people need to work close to the cell, where floor space is restricted, or where full guarding would obstruct access. It is also a straightforward first automation project, because it integrates into an existing line with minimal disruption.

It is not the right answer to every application. Where throughput requirements are higher, or where open trays or heavier cases are handled, a compact or modular system using a 140 kg industrial robot is usually the better specification. We will say so during a site assessment rather than fit a cobot to an application that does not suit one.

Automated Container Unloading: Why It Stayed Manual, and What Changed

Container unloading, also known as destuffing, is one of the few operations in a modern supply chain still carried out almost entirely by hand.

A container is opened, and two or three people work inside it, lifting cases onto a pallet or a conveyor. The work is heavy, the space is confined, and in summer the internal temperature is uncomfortable. It is among the most difficult jobs on any site to recruit for and retain.

The reason it has remained manual is technical rather than commercial, and that reason has now largely been removed.

Why container unloading resisted automation

A palletiser at the end of a production line handles one product size for a long production run. A container does not present product in that form.

A single container may hold several different case sizes. The sequence in which they appear depends on how the container was loaded, which is outside the receiving site’s control. Mixed and part-loads are routine.

On a conventional palletiser, each new case size requires a new stack pattern and, with it, new robot paths, clearances and speed profiles. Setup takes hours or days and requires a robot programmer. Applied to a container holding six case sizes, the programming time exceeds the unloading time by a wide margin.

This is why the operation remained manual. The constraint was changeover time, not the handling itself.

How an automated container unloading system is configured

The basic arrangement uses a boom conveyor that extends into the container. Product is placed onto the conveyor and carried out to a palletising cell, where it is stacked automatically.

The system is designed around the site’s requirements and can include:

  • Pallet stretch wrapping, inline or standalone
  • Labelling
  • Automatic pallet feeders and slip-sheet stacks
  • Barcode reading
  • Loading-dock or mobile boom conveyors

Palletising speed is matched to the process. Standard pick-and-place is used where throughput allows; layer forming is used where higher rates are required.

The programming requirement

Because a container presents a changing product size, the practical question is how the system is set up for each one.

Granta’s palletising software is configured by entering four dimensions: length, width, height and weight. From these it generates the viable stack patterns, ranks them by pallet efficiency, and derives the robot paths, clearances, safety zones, speed profiles and the orientation and grouping of product on the infeed conveyors. Setup for a new case size takes approximately five minutes and requires no robot-programming skill.

For container unloading, the automatic programming option is generally the more relevant configuration. A laser measuring system measures each case as it travels along the conveyor, identifies a change in size, generates the new stack pattern and continues stacking on a single confirmation press.

This is what makes automated palletising of a mixed container practical. The system adapts to the case sizes as they emerge, rather than requiring them to be known and programmed in advance.

What the operation looks like once automated

The manual task is reduced to placing cases onto the boom conveyor inside the container. Everything downstream — conveying, stacking, wrapping, labelling and pallet handling — runs without intervention.

The measurable effects are:

  • Heavy repetitive lifting reduced to a single, lighter transfer at the container face
  • Consistent unloading rate, unaffected by shift length or temperature
  • Square, stable pallets built to an optimised pattern and ready to wrap
  • Fewer people required for a job that is persistently hard to staff
  • Reduced demurrage exposure where container turnaround is time-limited

Where pallets then have to be moved to storage or dispatch, AMRs and AGVs can carry out that movement, which removes the remaining forklift traffic around the dock.

Assessing whether it applies to your site

Automated container unloading is normally justified where several of the following are true:

  1. Containers are unloaded regularly rather than occasionally
  2. The work is currently done by hand, by two or more people
  3. The dock area has, or can be given, space for a palletising cell
  4. Container turnaround time is a commercial constraint
  5. The role is difficult to recruit for or has high turnover

The case sizes involved do not need to be consistent, and do not need to be known in advance. That was the historical constraint, and it is the one that automatic programming removes. The wider manual handling case for automating heavy repetitive lifting is set out separately in Manual Handling Risks in Palletising.

Manual Handling Risks in Palletising: Hazards, HSE Duties and Control Measures

Ask a health and safety manager where the risk sits in a factory and end of line comes up almost every time.

It is the same task, repeated: lift a case off a conveyor, twist, place it on a pallet. Then again, several hundred times a shift. Nothing dramatic ever happens. The damage is cumulative, which is exactly why it is so easy to leave alone.

That position is getting harder to hold.

The hazard: why end of line carries the heaviest handling

Palletising is usually the heaviest repetitive manual task on a production line, and that is a function of where it sits rather than how it is organised.

Everything upstream is handled in its lighter state — individual products, empty cartons, part-filled packs, components. By the end of the line the product is finished: filled, sealed, cased and at its final weight. It is also the point where the whole line converges, so every unit the process makes passes through the same pair of hands.

Highest weight and highest volume, in the same place. That is why end of line still carries the manual handling risk on sites that are well automated everywhere else.

The task itself is a repeated lift-twist-place cycle, typically several hundred times a shift. The recognised risk factors are all present: repetition, forceful exertion, trunk rotation, reaching at height as the pallet builds, and little variation in the movement. Injury is cumulative rather than acute, which is why the risk is often carried for years without a recorded incident.

What the HSE figures show

The Health and Safety Executive’s figures for 2024/25 make the scale clear. An estimated 511,000 workers in Great Britain were suffering from a work-related musculoskeletal disorder, including 173,000 new cases. Those conditions accounted for 7.1 million lost working days — an average of 14 days for every affected worker.

Backs are the biggest single category, at 43% of cases, with upper limbs and neck close behind at 41%.

HSE puts the total cost of workplace injuries and new cases of ill health at £22.9 billion a year.

Progress has stalled. Self-reported musculoskeletal disorders were trending downwards before the pandemic. They have now settled back at broadly pre-pandemic levels rather than continuing to fall.

Employer duties: the Manual Handling Operations Regulations 1992

The Manual Handling Operations Regulations 1992 set a clear order of priority. Avoid hazardous manual handling so far as is reasonably practicable. Where it cannot be avoided, assess it. Then reduce the risk.

Avoidance comes first. And what counts as “reasonably practicable” depends on what is realistically available at the time.

Twenty years ago, a palletising robot was a major capital project that a mid-sized manufacturer could reasonably say was out of proportion to the risk. That argument has weakened. Standardised systems are now openly priced — our prebuilt palletiser starts at £57,900 + VAT — leasing is available, and payback is often inside a year.

When an affordable, proven engineering control exists for a task that is causing injuries across the industry, the case for continuing to do it by hand becomes harder to write down. It is worth asking how your own risk assessment reads on that point today, rather than when it was last reviewed.

Workforce and staffing factors

The health and safety argument used to run into a practical objection: we’ll just staff it.

That is no longer straightforward.

Fewer people want repetitive manual lifting work, and those who do have other options. Sites report constant churn on end-of-line roles, agency cover at premium rates, and vacancies that stay open. An ageing workforce makes heavy repetitive tasks less viable over a full career, and each new starter needs training and supervision before they are productive.

There is also the hidden cost of variability. Hand-stacking slows as a shift wears on. Pallets built at the end of a long day are less consistent, which shows up later as transit damage and rejected loads.

Absence compounds all of it. One person off with a back injury on a two-person stacking role usually means the line either slows down or someone works harder to cover, which is how the next injury starts.

Engineering controls at end of line

A palletising cell takes the lifting out of the job entirely. The operator’s role becomes supervising the line, changing over products and dealing with exceptions — work that people are happy to do and that keeps them on site.

Three points are worth knowing when you’re assessing the options:

People working alongside the system. A cobot palletiser can work in a shared space with the right safety assessment, using guarding, light curtains or area scanners depending on the layout. There is more than one way to make it safe, and the right one depends on your floor.

Forklifts and pedestrians. A lot of sites are trying to reduce forklift movements in occupied areas, or remove them altogether from food production and pedestrian zones. Our compact palletiser is built for that. The finished pallet comes off at floor level and is taken away with a pallet truck, while empty pallets are still fed automatically at speed — a combination rarely available elsewhere, and one we have patent applied for.

The journey after the pallet is built. Once a pallet is wrapped, something moves it. AMRs and AGVs take over the repeated short runs between palletiser, wrapper and dispatch, which is usually where the remaining forklift traffic sits.

Assessing the case

Health and safety arguments often stall because they are presented on their own. They land better alongside the operational ones, because the same change fixes several problems at once:

  • Lifting and twisting removed from the task
  • Lost days and claims exposure reduced
  • End-of-line roles that are easier to recruit for and keep
  • Consistent pallet quality across a full shift, and less transit damage
  • Throughput that holds steady rather than tailing off

We provide payback, ROI, OEE and intangible-benefits calculators, and will work through the figures for your own line so the case can be put to your board with real numbers rather than industry averages.

Case Study: Automating the Palletising of Insulation Batts with the Granta Cobot Palletiser

Sector: Manufacturing – passive fire protection / fire-stopping products
Application: End-of-line palletising of insulation batts
Solution: Granta Cobot Palletiser

Granta cobot palletiser stacking insulation batts

Overview

A UK manufacturer of fire-stopping products set out to automate the palletising of insulation batts at the end of one of their production lines. The packs were being hand-stacked by operators in a pre-defined pattern — a process that was physically demanding, inconsistent in speed, and capping the line’s true output.

Granta Automation supplied a Cobot Palletiser: a compact, collaborative system that now stacks every pallet to an identical, repeatable standard, removes the manual handling, and gives the line a reliable, consistent output it didn’t have before.

The Challenge

At the end of the line, production operators stood and manually stacked packs onto pallets for despatch, following a pre-defined stack pattern. While it worked, the manual approach carried three persistent problems:

  • Health and safety risk. Repetitive manual handling and lifting exposed operators to the risk of repetitive strain injury (RSI) and other injuries.
  • Inconsistent output speed. Because stacking depended on individual operators, the pace varied — which made line output unpredictable and constrained overall throughput.
  • Variable stack quality. With pallets built by hand, consistency came down to the individual, leaving room for stacking errors that can cause problems further down the supply chain.

The business wanted to reduce the risk of injury to its people, increase line output productivity, and put the end-of-line process onto a more reliable, repeatable footing.

Building the Business Case

Before committing, the customer worked through a full cost of not automating analysis with Granta — looking well beyond the obvious. The exercise weighed up the factors that quietly erode margin when an end-of-line process is left manual, including:

  • Production reliability and running time — the value lost to variable pace and stoppages across shifts.
  • Faster production — the additional output value unlocked once the line is no longer paced by hand-stacking.
  • Defective product — damage and stacking-quality issues that create problems in transport and storage.
  • Health and safety — the cost of absence, claims and HR challenges tied to manual handling and RSI.
  • Reliability and resourcing — the cost and difficulty of recruiting and covering manual roles.

Importantly, the strongest return wasn’t a single line item — it was the cumulative effect. As Granta consistently sees across installations, the biggest payback comes from an uplift in production combined with the intangible gains: fewer H&S issues, reduced HR burden and improved staff morale. Because an automated cell holds a steady takt time — it doesn’t take breaks, call in sick or pause for conversations — customers typically see a 30%+ increase in production throughput they hadn’t even priced into the business case.

This case also reframed the role of the team. Rather than being about removing people, automation removed a repetitive, physically demanding task — freeing operators from injury-prone manual handling and allowing that effort to be redirected to more skilled, higher-value work.

The Solution: The Granta Cobot Palletiser

Granta recommended its Cobot Palletiser — a high-payload collaborative robot ideally suited to a line where space is tight and consistency matters. Key reasons it fit this application:

  • Small footprint. A compact, self-contained cell that slots into a constrained end-of-line space without a major reorganisation.
  • High payload. A genuinely high weight-load capability, comfortably handling the packs coming off the line.
  • Genuinely simple programming. Granta’s easy-programming software lets operators set up and adjust stack patterns themselves — no specialist robot programmer required.
  • Efficient, built-in safety systems. Collaborative safety features allow the system to work safely in a shared, space-constrained environment.
  • A cost-effective package. High capability and consistency without the cost or complexity of a large conventional palletising installation.

The Results

  • Every pallet is now identical. Stack quality no longer depends on the individual — the system guarantees the same result every time, every shift.
  • Manual handling removed from the end of the line, sharply reducing the risk of RSI and lifting injuries.
  • Reliable, consistent output. A steady, automated takt time replaces operator-to-operator variation, lifting and stabilising line productivity.
  • A future-proofed line. Simple in-house reprogramming means the system can adapt as pack patterns and requirements change.

The Investment and the Return

Set against the cost of running the line manually, the payback was rapid. Granta’s cost-of-automation analysis showed the complete solution — palletising system plus operator training — paying for itself in under five months, with a significant net return in every year that followed.

That’s before accounting for the harder-to-quantify benefits: improved safety, consistently high stack quality and reliable, predictable output.

In the Customer’s Words

“I chose the Cobot palletiser from Granta because it has a very small footprint and a very high weight load. The system is very easy to use — programming is unbelievably simple. On the quality side, I can now guarantee that every pallet is the same when it leaves this factory, whereas before it was down to individuals. I’d recommend the Cobot system for its small footprint, high weight load, unbelievably efficient safety systems, and because it’s a genuinely cost-effective solution.”

Why “Ease of Use” Is the Most Important Metric in Robotic Palletising

When manufacturers compare robotic automation systems, the spec sheets all shout about the same things: cycle speed, payload capacity, reach, repeatability. These numbers matter — but they’re not what determines whether your automation project succeeds or fails.

The metric that actually decides your return on investment is one that rarely appears on a datasheet: ease of use.

A robotic palletiser that stacks 30% faster on paper but sits idle every time a product changes — because nobody on shift knows how to reprogram it — is slower in practice than a simpler system your operators can run confidently every day. In today’s world of manufacturing, usability isn’t a nice-to-have. It’s the number one predictor of real-world performance.

What Does “Ease of Use” Actually Mean in Robotics?

Ease of use in robotics means that the people who work with the system every day — line operators, shift supervisors, warehouse staff — can set up, run, adjust, and recover the system without needing a specialist robot programmer.

In practical terms, an easy-to-use robotic system should allow your team to:

  • Set up a new product run in minutes, not days
  • Change stack patterns or product sizes without writing code
  • Recover from a stoppage quickly and confidently
  • Train new operators in hours rather than weeks

If any of those tasks requires an external engineer or a six-figure specialist on the payroll, the system isn’t easy to use — no matter how impressive its speed figures are.

Why Ease of Use Beats Speed, Payload and Every Other Spec

1. Downtime is where ROI goes to die

Robotic palletisers only generate returns while they’re running. With traditional palletising software, introducing a single new stack pattern can take a trained specialist one to two days of coding and testing. If your production runs are getting shorter and your SKU count is growing — as it is for most manufacturers — those programming delays compound into serious lost output.

An easy-to-use system flips that equation. When operators can switch between product sizes or pallet layouts in minutes, changeovers stop being a bottleneck and utilisation stays high. That’s the difference between a payback period measured in years and one measured in months.

2. The skills shortage is real — and it isn’t going away

The UK manufacturing sector faces a persistent shortage of skilled engineers and robot programmers. According to the Institution of Engineering and Technology’s 2025 Skills Survey, 76% of engineering employers struggle to recruit for key roles — with automation among the top digital skills they need for growth. And the gap isn’t closing: EngineeringUK estimates the UK needs more than 173,000 new engineers and technicians every year through 2030 just to meet demand.

Building your automation strategy around scarce, expensive specialist skills is therefore a risk. If the one person who can reprogram your robot is on holiday, off sick, or leaves the business, production grinds to a halt.

Systems designed for ease of use remove that single point of failure. The benchmark to look for: if an operator can use a modern smartphone, they should be able to program the palletiser. That’s how you future-proof automation against a tight labour market.

3. Operator adoption makes or breaks the project

The most common reason automation projects underdeliver isn’t technical failure — it’s human resistance. When a new system is intimidating, staff work around it, blame it, or quietly stop using its capabilities. When a system is intuitive, operators feel empowered and take ownership of it.

Easy programming also delivers something spec sheets can’t measure: it moves people away from repetitive, injury-prone manual lifting and into supervisory roles. Manufacturers who automate palletising with genuinely usable systems routinely see manual handling injury claims fall to zero — and a happier, more stable workforce alongside.

4. Flexibility is the new productivity

Modern production is defined by shorter runs, more SKUs, and faster product changes. A “fast” robot that takes days to reprogram is optimised for a manufacturing world that no longer exists.

The latest developments in palletising software show where the industry is heading: systems that automatically generate optimised stack patterns from product dimensions, visual drag-and-drop pattern editors, and even fully automatic programming using laser measurement — where the system detects a new product size as it enters the cell and offers to create a new stack pattern itself, with no programming input at all.

That level of usability makes automation viable even for very short production runs — as little as a single pallet load — which was previously impossible because setup time was prohibitive.

How to Evaluate Ease of Use Before You Buy a Palletiser

Speed and payload are easy to compare. Usability takes slightly more digging, but these questions will reveal it quickly:

  1. Who programs a new product? If the answer involves a service call or a specialist engineer, walk away — or budget for that dependency forever.
  2. Does it offer genuinely easy programming? How long does a new stack pattern take? Minutes is the modern standard. Hours or days is legacy technology.  Look for easy programming features like automatic stack pattern generation – operators should never need to touch code.
  3. How long does operator training take? A genuinely usable system should have a new operator confident within a shift.
  4. What does fault recovery look like? Clear on-screen guidance beats an error code and a manual.
  5. Ask to see it live. A demonstration — ideally with one of your products — will tell you more about ease of use than any brochure.

The Bottom Line

Speed, payload and reach tell you what a robot can do in perfect conditions. Ease of use tells you what it will actually do on your factory floor, on a wet Tuesday, with a new starter on shift and a product changeover due before lunch.

When you evaluate robotic palletising systems, put usability at the top of your criteria — because the best palletiser isn’t the one with the most impressive spec sheet. It’s the one your team actually uses, every day, at full capacity.

FAQs: Ease of Use in Robotic Palletising

What is the most important factor when choosing a robotic palletiser? Ease of use. A palletiser your own operators can program and run without specialist support delivers higher real-world utilisation, faster changeovers, and a shorter payback period than a faster system that depends on external programmers.

Do you need a robot programmer to run a robotic palletiser? Not with modern systems. Easy-programming palletiser software allows operators with zero coding experience to set up a new product run in under five minutes, using automatically generated stack patterns or a visual drag-and-drop editor.

How long does it take to set up a new product on an easy-to-use palletiser? With modern easy-programming software, typically under five minutes. With fully automatic laser-measuring systems, the palletiser can detect a new product size itself and generate a new stack pattern with no manual programming at all.

Are easy-to-use palletisers suitable for short production runs? Yes. Because setup time is measured in minutes rather than days, automated palletising is now viable for very short runs — even a single pallet load.

Do easy-to-use palletisers reduce workplace injuries? Yes. By making automation simple enough for every operator to run, staff move away from repetitive manual lifting. Manufacturers automating palletising have reduced manual handling injury claims to zero.

Fast Palletiser Installation: Real Customer Experiences of Going Live in Under 48 Hours

How long does it take to install a palletiser? For our customers, the answer was less than 48 hours from uncrating to stacking the first case on a pallet — not the 2+ weeks of downtime they were quoted elsewhere.

In this short video, real customers share their experience of a Granta installation — from arrival on site to full automation.

Most companies dread automation installs because of the production downtime. But it doesn’t have to be that way. Here’s what the video covers.

Installed by the end of day one

One customer was quoted a minimum of two weeks’ installation time elsewhere, with multiple engineers on site. Our team had their system installed by the end of the first day. A big reason for that speed is our patented modular palletiser design — the system arrives largely pre-built and pre-tested, so time on your factory floor is kept to a minimum.

Picking its first case in under 48 hours

From the moment the system arrived and was uncrated, to the moment it picked its first case and stacked it on a pallet, took less than 48 hours. That’s what installation should look like: measured in days, not weeks.

Three days of hands-on, on-site training

A fast install means nothing if your team can’t run the machine confidently. At one customer’s site in Whitton, our engineers stayed for three days of hands-on training, helping both the engineering and production teams set up and fully automate the machine.

Staying on to iron out integration issues

Our team then stayed a further day to supervise live operation — and resolved communication issues between the palletiser and other parts of the production line’s control system before leaving site. Integration problems are dealt with there and then, not left for you to discover on Monday morning.

Immediate post-installation support

When questions came up after the install, the response was immediate. As one customer put it, our engineers came out, sorted any problems quickly, and trained their staff thoroughly on every feature they asked for.

What installation should look like

Fast installation, thorough operator training, and responsive after-sales support — so your team actually succeeds with the machine. If you’re a manufacturer or production manager looking at case palletising, bag palletising or end-of-line automation with minimal downtime, this is how it should be done.

Palletiser Support: How We Keep the UK’s Largest Factories Moving

Palletiser downtime is rarely a crisis — product can usually be palletised manually in the short term, and where upstream production is sensitive to stoppages we often design in a dedicated offtake lane. But workarounds are still workarounds, and getting you back to full automation quickly matters. That’s why, at Granta, support isn’t an afterthought bolted onto the sale — it’s designed into everything we do, from the way we build our systems to the way we answer the phone.

Here’s how we keep palletisers running in some of the busiest factories in the UK and Ireland.

Support from the team that built your system

Our service and support is in-house and UK-based. When you call us, you’re not speaking to an overseas call centre or a third-party contractor — you’re speaking to the same team that designed, built and commissioned your system. They know your line, your product and your layout, which means faster diagnosis and fewer wasted visits.

We’re based in Linton, Cambridge, with our own design, build and assembly facilities, and we install and support systems nationwide across the UK and Ireland with our own team of remote engineers.

Remote support that resolves issues in minutes, not days

Every Granta system can be connected via ethernet or Wi-Fi, allowing our engineers to log in remotely, see exactly what the system is seeing, and in many cases diagnose and resolve the issue there and then. For a busy factory, that’s often the difference between a few minutes of downtime and waiting for an engineer to travel to site.

Where a site visit is needed, remote diagnosis means our engineer arrives knowing what the problem is — and with the right parts on the van.

A support contract built around your operation

Our standard support package includes three service visits per year, plus on-site and remote support. For operations running around the clock, cover can be extended right up to 24/7 — because we know that for many of our customers, night shift matters just as much as day shift.

During service visits our engineers check, adjust and maintain the system to keep it running at its best, helping you catch small issues before they become stoppages.

Spares, obsolescence and long-term supportability

A palletiser is a long-term investment, so we build for the long term. Our systems use current, long-life KUKA and Yaskawa robots, PLCs and HMIs with extended manufacturer support — and as a KUKA Platinum partner and Yaskawa partner, we have direct access to the people who make them.

We supply spare parts, provide a suggested spares list for your system, and can even integrate with your own stock system where that’s useful. We’ll also advise on lifecycle and recommended spares, so your system stays fully supportable for years to come.

Systems designed to be easy to run — and easy to fix

The best support call is the one you never need to make. Our patented easy-programming software means your own operators set up new stack patterns in around five minutes, with no robot skills required — so a product change never leaves you waiting for a specialist programmer.

Training that puts your team in control

Support starts on day one. Training is included as part of every installation, covering both operations and engineering staff — classroom sessions on safety, programs and fault conditions, followed by practical training on your actual system, with a knowledge test and certificates issued.

For engineering teams who want to go further, optional advanced training covers advanced programming, hardware, detailed fault diagnostics and routine maintenance checks. The more capable your team is, the less downtime you’ll ever see.

Data that helps you improve, not just recover

Our systems can log production and downtime data and generate reports, helping you track OEE and continuously improve the line. Good support isn’t just about fixing problems — it’s about giving you the information to prevent them.

Whether you’re running one of our systems or planning your first palletising project, we’re happy to help.

How to Identify Bottlenecks in Your End-of-Line Packaging Process

An end-of-line bottleneck is the stage of your packing, palletising, wrapping, or despatch process that limits the output of your entire production line. However fast the rest of your line runs, it can only ever produce at the rate of its slowest stage — which is why finding that stage is one of the most valuable exercises any manufacturer can carry out.

Most production lines are carefully measured and monitored at the front end. Filling speeds, packing rates, and machine performance are all tracked closely. Yet it is very often the end of the line — where products are boxed, palletised, wrapped, and moved away — where output quietly slips. Because this part of the process is frequently more manual and less instrumented than the rest of the line, a production line bottleneck here can go unnoticed for a long time, and its cost can be far greater than it first appears.

The good news is that end-of-line bottlenecks are usually straightforward to find once you know what to look for. Below, we walk through the practical steps we recommend to any manufacturer who suspects their line is capable of more than it is currently delivering.

The Common Signs of an End-of-Line Bottleneck

Before any measurement, there are some telltale signs that your end-of-line packaging process is holding your line back. The most common signs of an end-of-line bottleneck are:

  • Product or boxes regularly accumulating ahead of one particular station
  • Upstream machines frequently stopping because the line behind them is “blocked”
  • Downstream equipment or operators intermittently standing idle, waiting for work
  • Output falling away in the second half of a shift as manual handling fatigue sets in
  • The line coping at average demand but struggling at peak or on your fastest products

If one or more of these sounds familiar, the following steps will help you pinpoint exactly where the constraint lies.

Start by Walking the Line

It sounds simple, but the single most valuable first step is to stand at the end of your line and watch it run for a full shift, or as much of one as you can. Not for five minutes — bottlenecks often hide during short observations and only reveal themselves over time.

As you watch, ask yourself a few questions. Where is product accumulating? Where are operators waiting? Where is equipment sitting idle? A build-up of boxes ahead of a workstation, or an operator standing empty-handed downstream of one, are both telling you the same thing: the constraint is somewhere in between.

Look for the Queue and the Gap

Every bottleneck produces two signatures. Immediately upstream of it, you will see a queue – product backing up, conveyors running full, or totes and boxes stacking on the floor. Immediately downstream, you will see a gap – equipment or people intermittently starved of work.

If boxes are accumulating before your palletising station while the stretch wrapper beyond it stands idle, the palletising step is your constraint. If pallets are queuing for the wrapper instead, the constraint has moved. Finding the point where “full” turns to “empty” is the quickest way to locate a bottleneck without any measurement equipment at all.

Measure the Rate at Each Stage

Observation will point you in the right direction, but numbers will confirm it. Take each stage of your end-of-line process in turn — case packing, check weighing, labelling, palletising, wrapping, and despatch — and measure the actual sustained rate of each, in units per hour, across a realistic period.

The word sustained matters here. A stage that runs quickly for ten minutes and then stops for five is not delivering its headline rate. What you are looking for is the true average output over a full shift, including all the stops, changeovers, and interruptions that happen in real production. Your bottleneck is simply the stage with the lowest sustained rate — and your whole line can only ever run as fast as that stage allows.

Don’t Overlook the Human Factors

At the end of the line, people are very often doing the heaviest and most repetitive work in the factory — lifting boxes, stacking pallets, and moving loads. This introduces a type of bottleneck that machinery does not suffer from: fatigue.

An operator hand-stacking pallets may comfortably match the line speed at 8am, but by mid-afternoon the rate naturally drops. Breaks, rotation, fatigue, absence, and the ongoing difficulty of recruiting for manual roles all affect end-of-line output in ways that a spot check will never reveal. If your line consistently produces less in the second half of a shift than the first, manual handling at the end of the line is a very likely cause.

Check Your Downtime Records

If you keep downtime logs, they are a rich source of evidence — but read them carefully. It is common for downtime to be recorded against the machine that stopped, rather than the machine that caused the stop. A filler that halts because the line behind it is backed up will appear in the log as filler downtime, when the real culprit may be a palletising station much further downstream.

Wherever you see repeated “blocked” or “waiting” entries, trace them back to their source. Bottlenecks at the end of the line have a habit of showing up as apparent problems everywhere else.

Watch What Happens at Peak

Many end-of-line processes cope perfectly well at average demand and fail at peak. If your bottleneck only appears during your busiest weeks, seasonal ramps, or when running your fastest products, it is no less real — it is simply intermittent. Make sure your observations and measurements include your most demanding production scenarios, not just a typical day, because it is at peak that a bottleneck costs you the most.

Beware of Moving the Problem

One final word of caution: bottlenecks move. Speed up your palletising and the constraint may shift to your stretch wrapper; automate your wrapping and it may shift to how quickly finished pallets are moved to storage. This is entirely normal, and it is why we always encourage customers to look at their end-of-line process as a whole system rather than a series of isolated stations. The goal is a balanced line, where every stage — including the transport of finished pallets away from it — can comfortably sustain the rate the line demands.

How to Fix an End-of-Line Bottleneck

In our experience, the end-of-line bottleneck most commonly turns out to be palletising — either a manual operation that cannot sustain the line rate across a full shift, or an older machine that stacks quickly on paper but stops frequently in practice. The second most common is pallet logistics: full pallets not being moved away fast enough, so the palletiser itself ends up blocked.

Both are very solvable. The most effective way to remove an end-of-line bottleneck is to automate the constraining stage — most often with a robotic palletising system that can sustain the line rate hour after hour without fade, supported by AMRs that keep finished pallets flowing away from the line automatically. Just as importantly, a well-specified system is designed to a realistic, agreed throughput target — with headroom for real-world variation — and proven against that target before it ever reaches your factory floor.

Talk to Us

If you suspect there is a palletising bottleneck in your end-of-line process, or you have found one and would like help removing it, we would be very happy to talk it through with you. We can help you assess your current line, identify where the constraint really lies, and recommend the right solution — whether that is a cobot, compact, modular or prebuilt palletiser, AMRs to move your pallets, or a combination.
