The short answer
No UK law fixes a service interval for industrial doors; the legal duty is to keep them safe and in efficient working order under a suitable system of maintenance. Industry practice treats one service every 12 months as the minimum, with more frequent visits for high-cycle doors, harsh or corrosive environments, or where the manufacturer's manual asks for it. Keep a service log.
Key points
- UK law sets no fixed service interval; it requires a suitable system of maintenance.
- Industry practice treats one service a year as the minimum for any powered door.
- Busy, high-speed and harshly sited doors need more frequent visits, ideally set by cycle count.
- Keep a door-by-door record of findings, tests, parts and outstanding defects.
- Planned maintenance is a guide £85 to £175 per door per visit, ex VAT, confirmed in writing.
Is there a legal service interval for industrial doors?
No. Neither the Workplace Regulations nor PUWER set a fixed interval for servicing industrial doors; they require doors and their safety devices to be maintained in an efficient state, in efficient working order and in good repair, under a suitable system of maintenance where appropriate. HSE's Approved Code of Practice lists powered doors as an example of equipment that needs such a system, and says how often maintenance happens depends on the equipment and the manufacturer's information.
So the interval is a decision you make, and should be able to justify, based on:
- the manufacturer's maintenance instructions for that door;
- how many cycles the door makes;
- the environment it works in;
- your risk assessment, including who uses the opening;
- the door's age, condition and repair history.
The same principles apply in Northern Ireland under its own Workplace Regulations (1993) and PUWER (1999).
What frequency should you start from?
Start from at least one service every 12 months for any powered door, then shorten the interval for doors that work hard or live in harsh conditions. The table shows typical starting points for a maintenance plan; the manufacturer's manual takes priority where it asks for more.
| Door and use | Typical starting interval | Why |
|---|---|---|
| Manual or powered door used a few times a day | Every 12 months | Industry minimum; springs and cables still age |
| Powered door used throughout each shift | Every 6 months | Wear on springs, cables, guides and seals builds quickly |
| High-speed or very high-cycle door | Every 3 to 4 months, or by cycle count | Drives, curtains and detection need regular adjustment |
| Corrosive, wet, dusty or coastal environment | Shorten the interval above | Corrosion of cables and fixings, debris in guides |
| Fire shutter | At least annually, often six-monthly, with a drop test | Must close as tested in a fire |
| Dock leveller and shelter | Per manufacturer; busy bays often more than once a year | Hydraulics, lip hinges and safety legs carry heavy loads |
What does a proper service include?
A proper service is an inspection, adjustment and test of every part that keeps the door working and safe, followed by a written report. On a powered sectional door or roller shutter the engineer should:
- check springs, lifting cables, drums, barrels and end plates for wear, corrosion and fraying;
- test anti-drop, spring-break and cable-break devices where fitted;
- inspect guides, tracks, rollers, hinges and fixings, and clean debris from guides;
- check balance, so the motor is not doing work the springs should do;
- test safety edges, photocells and light curtains, and confirm the door reverses or stops as designed;
- check limit settings, the emergency stop and manual operation;
- carry out force measurement where force limitation is a protective measure;
- inspect the motor, gearbox, brake, controls and visible wiring;
- check seals, panels or laths, vision panels and locks;
- record findings, parts replaced and anything that needs follow-up.
A defence estate safety alert in 2020 described a roller shutter whose corroded motor cable failed and whose anti-drop device then did not work, after service sheets had recorded the cable as serviceable. Thorough, honest inspection of cables and safety devices is the point of the visit.
What should your service records show?
Your records should show, door by door, what was checked, what was found, what was done and what is still outstanding. PUWER requires any machinery maintenance log to be kept up to date, and HSE recommends keeping records of servicing and testing for powered doors.
A useful door record includes:
- a unique door reference, location, type, size and manufacturer;
- installation date and the original handover documents;
- each service date, engineer and findings;
- safety device test results and force readings where taken;
- parts replaced, with cycle counts where the controller records them;
- defects reported, the risk they pose and when they were closed.
Records like these also help with insurance enquiries and lease handbacks, and make it much easier to decide when repair stops making sense.
What should your own staff check between services?
Between professional services, the people who use the door every day should carry out simple visual and functional checks set out in the user instructions. These do not replace servicing, but they catch problems early.
- Is the door running smoothly, without new noises, jerks or hesitation?
- Does it stop and reverse when the safety edge or photocell is triggered?
- Are guides, tracks and panels free from impact damage?
- Are any cables visibly frayed, slack or off their drums?
- Is the door closing evenly and sealing at the floor?
- Are warning signs, manual release equipment and the emergency stop in place?
Staff should know never to disable a safety device and to report faults straight away. If a door is found to be unsafe, take it out of use until it is repaired.
When should a door be looked at before its next service?
A door should be inspected straight away, not at the next scheduled visit, if any of these happen:
- it is struck by a vehicle, even if it still appears to work;
- a spring, cable or chain breaks or looks damaged;
- it drops, runs unevenly or stops at the wrong point;
- a safety device fails to stop or reverse the door;
- it starts making new grinding, banging or slipping noises;
- it has been modified or had its controls changed.
Our industrial door repairs service handles call-outs; a repair visit covering attendance and the first hour is a guide £145 to £195, ex VAT. If the same door keeps appearing on this list, review its service interval, its protection from vehicles and how it is being used, rather than just repairing it again.
How much does a planned maintenance contract cost?
Planned maintenance is a guide £85 to £175 per door per visit, ex VAT, depending on the door type, how many doors are covered and how easy they are to reach. Fire shutter services with a drop test are a guide £125 to £265 per shutter.
A planned maintenance contract sets an interval for each door based on its use and condition, rather than one frequency for the whole site. Busy doors may be visited quarterly while a rarely used store door is seen once a year. Repairs found on a visit are quoted separately so you stay in control of spend. All figures are confirmed in writing before work starts.
Grouping doors, dock levellers and fire shutters into one schedule usually reduces visits and keeps all the records in one place. It also means one engineer sees how the site works, and can spot patterns such as the same door being struck every few months, which points to a traffic route or protection problem rather than a door fault.
Frequently asked questions
Is a yearly service enough for a busy warehouse door?
Often not. A door that cycles throughout every shift wears its springs, cables, guides and seals far faster than one used a few times a day. Most busy doors are better on a six-monthly or quarterly plan, and doors with cycle counters can be serviced by usage. The manufacturer's manual and your risk assessment should set the final interval.
Do manual doors need servicing too?
Yes. A manual roller shutter or sectional door still has springs, cables and fixings that wear and can fail, and upward-opening doors must have a device to stop them falling back. Manual doors need less frequent attention than powered ones, but an annual inspection and lubrication is a sensible minimum for most industrial sites.
Can we skip servicing on a brand-new door?
No. New doors need servicing at the interval in the manufacturer's instructions, and early visits often catch settling, spring adjustment or detection settings that need fine-tuning. Some manufacturers make warranty conditional on servicing. Keeping the record from day one also gives you a clean history for the life of the door.
What happens if a door fails its service?
The engineer records the defect, explains the risk and recommends action. If the door is unsafe to use, it should be taken out of service and isolated until repaired, and the engineer should not leave it in a dangerous state. Less urgent defects are quoted for repair. You decide on the work, and nothing is done without your approval.
