What we fit in Caernarfon

Traffic lights. Signals show drivers when the door is fully open and warn when it moves.
Safety devices. Safety edges, photocells and light curtains, force-tested to BS EN 12453.

Powered door rules that apply in Caernarfon

Caernarfon is in Wales, 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

For busy sites in Gwynedd the work can be split across visits — preparation and framing first, door installation and commissioning second — so the opening is only out of action for the shortest time.

Frequently asked questions

Can you add interlocks or traffic lights to doors around Gwynedd?

Yes. We fit airlock interlocks, door-to-leveller interlocks, traffic lights and warning beacons to new and existing doors across Gwynedd, subject to compatibility with the control panels already fitted, and replace panels where they cannot accept the extra inputs.

Do automated doors in Caernarfon need more maintenance?

Powered doors need their motors, controls and safety devices checked as well as the mechanical parts, so at least an annual service is common practice, more often for busy doors. Servicing visits are chargeable; the survey for an automation job is free.

How much does it cost to make a door electric in Caernarfon?

Our guide price for a manual-to-electric conversion is £1,195 to £3,195 ex VAT, including motor, control panel, basic controls and commissioning. Extra controls and safety devices are priced separately, and your fixed price in Caernarfon follows a free survey.
