Options for door safety upgrades in Hertfordshire
- Safety edges. Pressure-sensitive or optical edges that stop and reverse the door on contact.
- Fall protection. Spring-break, cable-break and anti-fall devices against suspension failure.
- Force testing. We measure how hard the door closes and record the results at each test point.
- Light curtains. Full-height multi-beam detection across the whole opening.
- Photocells. If something breaks the beam, the door will not close.
Typical scopes of work
- Force-testing a run of loading bay doors and adjusting closing speeds where results exceed the limits.
- Replacing a damaged or bypassed safety edge on a yard roller shutter and re-testing its closing forces.
- Fitting a full-height light curtain to an automatic sectional door on a busy pedestrian route.
Who is responsible for door safety at a site in Hertfordshire?
In England, two sets of duties meet at a powered door. The installer who supplies or motorises it must hand over a door that meets the Supply of Machinery (Safety) Regulations 2008, tested against BS EN 12453 and documented. The business in control of the premises must then maintain it: regulation 5 of the Workplace Regulations 1992 covers maintenance, and regulation 18 requires upward-opening doors to have a device that stops them falling back and powered doors to have features that prevent trapping.
How the work is organised
Downtime matters on a working site, so the programme is set around your shifts. For a single door the opening is usually needed for a day; multi-door jobs are done one bay at a time so deliveries keep moving.

Door safety upgrades in Hertfordshire: your questions
How much does a door safety upgrade cost in Hertfordshire?
Our guide price is £445 to £1,795 ex VAT per door for safety edges, photocells or a light curtain, depending on door size and devices. A new control panel or fall protection adds to it. We confirm the fixed price after a survey and force test in Hertfordshire.
Do you upgrade doors from other installers across the East of England?
Yes. We upgrade safety devices on most makes of powered door across the East of England, whoever installed them, checking that new devices are compatible with the existing control panel and replacing the panel where needed.
Our door at our Hertfordshire site has a bypassed safety edge. What should we do?
Stop using the door under power until the safety device is working, or use it on hold-to-run only if the risk assessment allows. We can replace the edge or fit alternative detection and re-test the door.
