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

After fitting, the door is tested to check it stops and reverses as it should with the new devices.
The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.
Where a door has never had photocells, any extra wiring needed is priced before we come out.

How does it work in Chesterfield?

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 Chesterfield

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 Chesterfield: questions

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

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

How much is a visit in Chesterfield?

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 Chesterfield as elsewhere we cover.

Do you cover Chesterfield?

Yes. Chesterfield is part of the area we cover in Derbyshire, including S41 and S40. 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 Chesterfield 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 I still need the manual override if I have a battery backup?

Yes. A battery unit covers a limited number of cycles, and it can run down during a long power cut or as the battery ages. Keep the override handle somewhere you can find it in the dark, and make sure everyone who uses the garage knows where it is and how it works.

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.
