- Refurbishing manual large-span sliding doors with new bottom wheels, top guides and an electric drive unit on each leaf.
Who is responsible for door safety at a site in Seaham?
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
Electrical work is the part that most often delays a job. If a new or converted door needs a supply, we confirm the motor's requirement at quote stage so your electrician can provide an isolator in the right place before installation day.
