Rules that apply in Brentwood
Electrics
An electric door needs a power supply near the roller box. Electrical work must meet BS 7671, and in England some domestic electrical work is notifiable under Part P, so it is done by a registered competent person or signed off by building control.
Powered door safety
Every powered door we fit is commissioned with force testing to BS EN 12453 and handed over with a Declaration of Conformity and UKCA or CE marking, as the Supply of Machinery (Safety) Regulations 2008 require.
Manual to electric roller door conversion in Brentwood: questions
What do you check at a survey in CM14?
At a survey in CM14 we measure the width and height of the opening, the headroom above it for the roller box, the side room for the guide rails and the floor level. We also look at the lintel and where power can come from for an electric door.
Do I need permission for a new roller garage door in Brentwood?
Replacing a garage door is not usually development that needs planning permission in England, and widening the opening needs building control approval. If you live in a listed building, a conservation area or on an estate with covenants or planning conditions, check before ordering.
Do you charge more for Brentwood than other towns in Essex?
No. Guide prices are the same for Brentwood as for anywhere else we cover in Essex. The written quote reflects your opening and the door you choose, not your postcode, apart from islands and remote areas where any travel cost is shown in advance.
Do you cover Brentwood?
Yes. Brentwood is part of the area we cover in Essex, including CM14, CM13 and CM15. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.
What safety devices are added to a converted door?
A converted door gets a pressure-sensitive safety edge on the bottom rail and, where the risk assessment calls for them, photocells across the opening. These stop or reverse the door if it touches or detects an obstruction. After fitting, the closing force is tested to BS EN 12453, and you receive a Declaration of Conformity along with the rest of the handover paperwork.
Is converting better value than buying a new electric door?
Compare the conversion price with the new-door prices on our prices page. A conversion keeps your existing curtain, barrel, box and guides, so it only makes sense when those parts are in good condition. If the door is worn, or you'd like insulated laths, a new electric door may be better value overall, and your quote can show both.
