Most roller shutters lead quiet lives. They go up in the morning, come down at night, and nobody gives them a second thought until the day one jams halfway, refuses to move or makes a noise it shouldn’t.
That’s understandable. A shutter isn’t a glamorous asset. But for a warehouse, a shop, a workshop or a block of commercial units, it’s often the main way into the building, the main barrier against intruders, and one of the heaviest moving objects on the site. And for businesses, keeping it in good working order isn’t just good practice. It’s a legal duty.
What the law says
In Great Britain, the main rules come from the Workplace (Health, Safety and Welfare) Regulations 1992. Two parts matter most for shutters:
- Regulation 5 requires workplace equipment, including powered doors, to be maintained in efficient working order and good repair.
- Regulation 18 requires doors and gates to be suitably constructed and fitted with any necessary safety devices. For powered doors, that means features that stop them trapping or injuring people, and a way of opening them if the power fails.
The Health and Safety Executive’s guidance adds that whoever controls the premises should make sure the door is safe and stays safe, check the competence of anyone working on it, keep records of servicing, repairs and tests, and make sure relevant people know how to switch it to a safe mode and how to release someone who is trapped.
Those duties don’t only fall on employers. Under the Health and Safety at Work etc Act 1974, landlords and managing agents who control shared doors on a multi-let site have similar responsibilities to anyone who might be affected, including tenants, visitors and members of the public.
How often is "regular"?
The HSE doesn’t set a single fixed interval for servicing powered doors, because use varies so widely. A shutter on a busy loading bay that cycles dozens of times a day faces very different wear from one on a back door that’s opened once a week.
What it does expect is periodic checks by someone competent, based on the manufacturer’s instructions and how heavily the door is used. In practice, many commercial shutters are serviced at least once a year, and more frequently where they’re in constant use or exposed to harsh conditions. The installer’s handover documents and the manufacturer’s instructions are the best starting point for setting a schedule.
What goes wrong when maintenance slips
Two cases prosecuted by the HSE show why this matters.
In the first, a recycling firm in Cwmbran was fined £50,000 after the roller barrel of a powered shutter fell on an employee, leaving him with cracked ribs and a damaged spleen. The HSE found that none of the powered shutters on the site had been properly maintained. The inspector said the case showed why regular, proactive maintenance and inspection of work equipment, including roller shutters, is so important.
The second is more sobering. In 2016, a woman in Cambridge died after becoming caught on the grille of a powered shutter as it lifted. The safety sensors at the top of the door had been wired incorrectly and didn’t work as the door opened. The contractor responsible had inspected the door a month earlier but hadn’t checked that the sensors worked. It was fined £25,000.
The lesson from the second case is important. A door being looked at isn’t the same as a door being properly inspected. A service visit needs to test the safety features, not just confirm the shutter goes up and down.
What a proper service should cover
A thorough service visit on a commercial roller shutter will usually include:
- Checking the curtain, laths and end locks for wear, damage or bending.
- Inspecting the guide rails and fixings to make sure the shutter is running straight and securely attached.
- Checking the barrel, springs and brackets, and the balance of the curtain.
- Testing the motor, controls and limit settings so the shutter stops in the right place at the top and bottom.
- Testing every safety device: safety edges, photocells and any other sensors that stop or reverse the door.
- Checking the manual override works, so the door can be opened in a power cut.
- Lubricating moving parts and making minor adjustments.
- Recording what was found and done, and flagging anything that needs repair.
That last step matters as much as the rest. A written service record is your evidence that the door has been looked after, which is useful for an insurer, a landlord, an HSE inspector or a future buyer of the property.
Day-to-day checks staff can do
Between services, the people who use the shutter every day are the first line of defence. Encourage them to report:
- Unusual noises, juddering or the shutter running unevenly.
- A curtain that’s slow to move, catches, or stops short of the top or bottom.
- Visible damage, such as bent laths or a damaged bottom rail.
- Safety devices that don’t seem to be working, or a door that doesn’t stop when something is in the way.
Any of those is a reason to stop using the door and get it checked, not to keep going until the next scheduled visit.
The business case, not just the legal one
Maintenance is easy to see as a cost. But a shutter that fails without warning brings its own bill: an emergency call-out, lost trading while the premises can’t be opened or secured, stock left exposed overnight, and in the worst case, an injury.
Regular servicing tends to catch small problems, a worn component, a slipping limit setting, a sensor out of alignment, before they become expensive ones. It also keeps motors and springs running within their limits, which extends the life of the shutter. Many installers offer annual servicing or maintenance contracts that spread the cost and make sure the visits happen on schedule.
For facilities managers and business owners responsible for one or more shutters, planned roller shutter maintenance carried out by a competent engineer is the simplest way to meet the legal duty and keep the doors working when they’re needed most.
Put it in the diary
The easiest way to fall behind on shutter maintenance is to rely on remembering it. A few simple steps help:
- Keep a list of every powered door on site, with its age and installer.
- Find the original handover documents and the manufacturer’s maintenance recommendations.
- Set a service schedule based on how heavily each door is used.
- Keep all service and repair records in one place.
- Make sure staff know how to report a fault, how to switch the door into a safe mode and how to use the manual override.
A roller shutter is one of those things that only gets noticed when it goes wrong. With a little planning, it can stay that way.
