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

The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.
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.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.

Covering Amersham and nearby

We survey and fit roller garage doors across Amersham, including HP7, HP6 and HP8, as part of our coverage in Buckinghamshire. Amersham lies around 13 miles from Aylesbury.

Rules that apply in Amersham

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 Amersham: questions

Do you cover Amersham?

Yes. Amersham is part of the area we cover in Buckinghamshire, including HP7, HP6 and HP8. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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

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

Will you fix the door on the first visit?

A fault can sometimes be found and put right on the first visit, but we never promise it. If a part needs ordering, we quote for it first, make the door safe where we can, and confirm the return date in writing.

How much is a visit in Amersham?

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 Amersham as elsewhere we cover.

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.

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.
