Options that matter on site
- Light curtains. Full-height multi-beam detection across the whole opening.
- Warning devices. Beacons, sounders and traffic lights to warn people of a moving door.
- Photocells. If something breaks the beam, the door will not close.
- Panel upgrades. Where the old panel cannot monitor devices, we replace it with one that can.

Powered door rules that apply in Grantham
Grantham is in England, where powered industrial doors fall under Great Britain's health and safety law. Whoever makes a door powered — including converting a manual door — usually takes on the manufacturer's duties under the Supply of Machinery (Safety) Regulations 2008: risk assessment, technical file, conformity marking and a Declaration of Conformity. Once it is in use, the employer or occupier must keep it safe under the Workplace (Health, Safety and Welfare) Regulations 1992 and PUWER 1998.
How the work is organised
Most installations in Grantham can be phased so part of the site keeps working. We agree access routes, exclusion zones and any temporary security with you before the team arrives, and can work early mornings, evenings or weekends where the business needs it.

Questions from businesses in Grantham
How much does a door safety upgrade cost in Grantham?
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 Grantham.
Our door at our Grantham 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.
Do our powered doors in Grantham need safety upgrades?
It depends on how they are controlled and used. Doors that close automatically or on a single press typically need edges and photocells or light curtains. A survey and force test shows whether your doors meet current expectations.
