Rules that apply in Harpenden
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 Harpenden: questions
How much does manual to electric roller door conversion cost in Harpenden?
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 Harpenden as elsewhere we cover.
Can I get a price for Harpenden 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.
Can I message you a photo of my garage in Harpenden?
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 Harpenden. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.
Is the survey in Harpenden 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.
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.
