What should I know about battery backup and safety upgrades in Northamptonshire?

The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.
You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.
After fitting, the door is tested to check it stops and reverses as it should with the new devices.

Rules that apply in England

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.

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.

Questions about battery backup and safety upgrades in Northamptonshire

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.

Are guide prices the same across Northamptonshire?

Yes. The guide prices are the same in every town in Northamptonshire. The written quote reflects your opening and the door you choose, not your postcode.

How do I book a visit in Northamptonshire?

Tell us what the door is doing using the form on this page, by phone or on WhatsApp. We confirm the visit price before anyone comes out, then confirm the date in writing.

How often should I test the safety edge and photocells?

Test them monthly, following the manufacturer's instructions for your door. The aim is to confirm that the door stops or reverses when the safety edge meets an obstruction, and won't close while the photocell beam is broken. If either test fails, don't keep using the door until it has been checked, and request a visit.

Can safety devices be added to an older electric door?

Usually, if a compatible safety edge or photocells are available for the control box. Some older systems need extra wiring or a replacement control box first. Tell us what's on the control box label and we'll confirm whether it can be done, and the price, before booking the visit.
