Rules that apply in England
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.
Questions about manual to electric roller door conversion in Cornwall
Can I get a price without anyone visiting?
Yes. The guide price tool takes four steps and gives a range for your opening and door type, or the visit price for a repair. It is a guide, not a quote: the written quote comes after the survey or once the visit price is agreed.
Do I need permission for a new roller garage door in Cornwall?
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.
Are guide prices the same across Cornwall?
Yes. The guide prices are the same in every town in Cornwall. The written quote reflects your opening and the door you choose, not your postcode.
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.
