Rules that apply in Larne
Electrics
An electric door needs a power supply near the roller box. Part P does not apply in Northern Ireland, but electrical work must still meet BS 7671 and be carried out by a qualified electrician.

Every powered door we fit is commissioned with force testing to BS EN 12453 and handed over with a Declaration of Conformity and CE marking, which is the marking that applies to machinery placed on the market in Northern Ireland.
Manual to electric roller door conversion in Larne: questions
Is the survey in Larne 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 do you check at a survey in BT40?
At a survey in BT40 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.
Can I get a price for Larne 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.
Is an electric roller door worth it for a garage in Larne?
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 Larne garage so you can compare.
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.
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.
