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

A battery backup unit lets the door run for a limited number of cycles when the mains power is off.
Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.
We check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.
You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.

Covering Christchurch and nearby

Our coverage in Dorset includes Christchurch and the BH23, BH6 and BH7 postcode districts, so the same guide prices and written quotes apply here. For reference, Christchurch sits roughly 28 miles from Dorchester.

Rules that apply in Christchurch

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.

Battery backup and safety upgrades in Christchurch: questions

Do you charge more for Christchurch than other towns in Dorset?

No. Guide prices are the same for Christchurch as for anywhere else we cover in Dorset. 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 message you a photo of my garage in Christchurch?

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 Christchurch. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.

Do you cover Christchurch?

Yes. Christchurch is part of the area we cover in Dorset, including BH23, BH6 and BH7. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Can I get a price for Christchurch 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.

How many times will a battery backup open the door?

It depends on the unit, the motor and the size and weight of the door. A battery backup is designed for a limited number of cycles in a power cut, not for running the door for days. If you need the door after the battery runs down, use the manual override as the manufacturer's instructions describe.

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.
