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

Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.
You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
After fitting, the door is tested to check it stops and reverses as it should with the new devices.
We check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.

How does it work in Acton?

We confirm the visit price and the cost of the battery unit, safety edge or photocells. The visit is booked, with the date confirmed in writing once an engineer is available.

Covering Acton and nearby

We survey and fit roller garage doors across Acton, including W3, W5 and W4, as part of our coverage in Greater London. Acton is about 6 miles from Westminster.

Rules that apply in Acton

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 Acton: questions

Can I message you a photo of my garage in Acton?

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

How much is a visit in Acton?

Prices for battery backup and safety upgrades start from £99 inc VAT, and the price is agreed before anyone comes out. Any parts not covered by that price are quoted before they are fitted, so you can decide on the spot. The guide prices are the same in Acton as elsewhere we cover.

Can I get a price for Acton 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 you cover Acton?

Yes. Acton is part of the area we cover in Greater London, including W3, W5 and W4. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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 a battery backup be fitted to a manual roller door?

No. A manual door has no motor or control box for a battery unit to power, because springs in the barrel balance the curtain and you lift it by hand. If you'd like powered operation, a manual-to-electric conversion may be possible when the curtain, barrel, box and guides are sound and compatible.
