What should I know about manual to electric roller door conversion in Isleworth?
- A safety edge on the bottom rail, and photocells where the risk assessment calls for them, stop or reverse the door on obstruction.
- A manual override lets you open the converted door in a power cut, and a battery backup unit can be added.
- Where there's no socket near the box, a qualified electrician fits a fused spur from an existing circuit, priced as a separate line.
- The engineer releases the spring tension and converts or replaces the barrel so a tubular motor can drive it, with a control box on the wall.

Rules that apply in Isleworth
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 Isleworth: questions
Do you cover Isleworth?
Yes. Isleworth is part of the area we cover in Greater London, including TW7, TW3 and TW5. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.
Is the survey in Isleworth 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.
Do I need permission for a new roller garage door in Isleworth?
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 get a price for Isleworth without anyone visiting?
Yes. The guide price tool takes four steps and gives a range for your opening and door type. It is a guide, not a quote: the written quote comes after the survey or once the visit price is agreed.
How do I know if my manual roller door can be motorised?
The only reliable way is a survey. We check that the curtain runs smoothly, the laths are undamaged, and the barrel, box and guide rails are sound and compatible with a tubular motor. If they are, we quote for the conversion; if not, we explain why and price a new electric door so you can compare the two.
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.
