Rules that apply in Harwich
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 Harwich: questions
How much does manual to electric roller door conversion cost in Harwich?
Our guide price for manual to electric roller door conversion is from £495 inc VAT. The figure for your garage depends on the opening size, the door specification and any extras, and is confirmed in a written quote after a free survey. The guide prices are the same in Harwich as elsewhere we cover.
Is an electric roller door worth it for a garage in Harwich?
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 Harwich garage so you can compare.
Can I get a price for Harwich 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.
Do I need permission for a new roller garage door in Harwich?
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.
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.
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.
