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

A battery backup unit lets the door run for a limited number of cycles when the mains power is off.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.
You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.

How does it work in Plymouth?

On the day, the upgrade is fitted and the door is tested. If anything else needs attention, the parts are quoted before they're fitted.

Rules that apply in Plymouth

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 Plymouth: questions

Do you cover Plymouth?

Yes. Plymouth is part of the area we cover in Devon, including PL4, PL1 and PL3. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

How much is a visit in Plymouth?

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 Plymouth as elsewhere we cover.

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

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

Do you charge more for Plymouth than other towns in Devon?

No. Guide prices are the same for Plymouth as for anywhere else we cover in Devon. 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 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.

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.
