What should I know about manual to electric roller door conversion in Dartford?
- A safety edge on the bottom rail, and photocells where the risk assessment calls for them, stop or reverse the door on obstruction.

Rules that apply in Dartford
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.

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 Dartford: questions
Do you cover Dartford?
Yes. Dartford is part of the area we cover in Kent, including DA1, DA2 and DA8. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.
What do you check at a survey in DA1?
At a survey in DA1 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 you charge more for Dartford than other towns in Kent?
No. Guide prices are the same for Dartford as for anywhere else we cover in Kent. 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.
Can I get a price for Dartford 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 an electrician for a conversion?
An electric door needs a power supply near the box, usually a fused spur or a socket. If you already have one in a suitable place, it can normally be used. If not, a qualified electrician fits a new fused spur, priced separately in your quote. In England and Wales some domestic electrical work is notifiable under Part P.
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.
