Rules that apply in Welwyn Garden City
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 Welwyn Garden City: questions
Is the survey in Welwyn Garden City really free?
Yes. For a new door, a replacement or a conversion, the survey is free and there is no obligation to go ahead. We measure the opening, check the lintel, headroom, side room and power, and send a written quote afterwards.
Is an electric roller door worth it for a garage in Welwyn Garden City?
That depends on how often you use the garage. An electric door opens from the car with a remote and has safety devices fitted, while a manual door costs less and suits occasional use. We price both for your Welwyn Garden City garage so you can compare.
Do I need permission for a new roller garage door in Welwyn Garden City?
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.
Can I message you a photo of my garage in Welwyn Garden City?
Yes. Photos of the opening, the inside of the garage above the door and any existing door help us give a more useful guide price for Welwyn Garden City. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.
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.
Will I still be able to open the door by hand?
Not in the way you do now, because the motor holds the curtain in place. Most electric roller doors have a manual override, usually an internal crank or winding handle, for use in a power cut. A battery backup unit can also be added so the door runs for a limited number of cycles when the power is off.
