Unplanned downtime is one of the most expensive problems facing UK manufacturers. Recent industry research puts the cost to UK manufacturers at up to £736 million a week, with equipment breakdown accounting for 42% of all incidents and the average outage lasting around four hours. For Lancashire’s manufacturing and industrial businesses, a roller shutter that fails to open, or worse, fails to close, is exactly the kind of equipment failure that brings a shift to a standstill.
It’s an easy risk to underestimate. A roller shutter operates dozens of times a day on a busy industrial site and, when it’s working properly, nobody thinks about it at all. That’s precisely why it’s often the piece of equipment that gets the least attention until the day it doesn’t open.
Why Shutters Fail Without Warning
Roller shutters are mechanical systems with motors, tracks, springs and safety devices that wear with use. A shutter operating up to 30 times a day, common on a busy loading bay, is under far more mechanical stress than one used a handful of times daily, and it needs a servicing schedule that reflects that.
Under the Provision and Use of Work Equipment Regulations 1998 (PUWER), powered roller shutters are classed as work equipment, and employers have a legal duty to keep them in efficient working order and good repair, with safety systems tested regularly. The regulations don’t set a fixed interval, they depend on the manufacturer’s guidance and how often the door is used, but the general industry benchmark is that a shutter operating up to 12 times a day should be serviced roughly every six months, rising to every four months for doors used up to 30 times daily. A detailed maintenance log is expected to be kept as evidence that this is actually happening.
What Gets Missed Without a Servicing Schedule
Across Lancashire’s industrial estates, the same pattern shows up repeatedly on sites without a formal maintenance contract:
- Worn tracks or guides that cause the shutter to run slower or judder, long before they cause a full failure.
- Motors under increasing strain that eventually fail completely, often during a busy period rather than a quiet one.
- Safety edges and sensors that stop working correctly, creating a compliance issue as well as a safety one.
- No documented service history, which becomes a problem both for PUWER compliance and for insurance claims if something does go wrong.
Each of these starts as a minor fault that a routine service would catch and resolve cheaply. Left unaddressed, they tend to end in a full breakdown, usually at the least convenient possible moment.
The Real Cost of a Breakdown
When a shutter fails on an industrial site, the cost isn’t limited to the repair itself. A jammed loading bay door can halt deliveries and despatch, disrupt production schedules further down the line, and in some cases leave a premises insecure until it’s fixed. For a manufacturer already absorbing the costs of unplanned downtime elsewhere in the business, an entirely preventable shutter failure is an unnecessary addition to that total.
Regular servicing is considerably cheaper than reactive repair. A scheduled visit catches wear before it becomes a failure, keeps the shutter compliant with PUWER requirements, and maintains the documented history that both regulators and insurers expect to see.
Building Maintenance Into the Operating Routine
The businesses that avoid shutter-related downtime are the ones that treat servicing as a fixed part of their maintenance calendar, not something scheduled reactively after a fault appears. That means agreeing a service frequency based on how the shutter is actually used, keeping a proper record of every visit, and having a clear point of contact for anything that needs attention between scheduled services.
For Lancashire businesses without a current servicing arrangement, or relying on an ad hoc approach, it’s worth reviewing when the shutters on site were last properly checked. A structured roller shutter maintenance contract keeps a shutter compliant, reliable and less likely to fail at the worst possible time, while building the documented history that PUWER compliance and insurance renewals both rely on.
What Good Compliance Actually Looks Like
Meeting PUWER requirements isn’t just about booking a service and moving on. A defensible record typically includes the date and outcome of every visit, any parts replaced or adjustments made, confirmation that safety devices such as sensors and edges were tested, and a clear note of when the next service is due. Businesses that can produce this on request, whether for an HSE inspection or an insurance review, are in a considerably stronger position than those relying on memory or an informal arrangement with whoever happened to be available at the time.
This is also where a maintenance contract earns its cost. A one-off callout doesn’t build the kind of continuous history that compliance and insurance both rely on, whereas a scheduled contract with the same provider creates exactly that record as a natural by-product of the work being done properly.
What Lancashire Businesses Should Do Next
Given how much unplanned downtime already costs UK manufacturers, a shutter failure is one of the more preventable contributors to that total. Reviewing the current servicing arrangement, or putting one in place where none exists, is a low-effort way to remove a genuine operational risk rather than waiting for it to become an expensive one.
A quick way to check exposure: is there a documented service date for every shutter on site? Does the frequency match how often the door is actually used? And would production stop if that shutter failed tomorrow? If the answer to any of these is uncertain, it’s worth having the conversation before the shutter forces it.
