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

A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.
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.

How does it work in Hatfield?

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.

Rules that apply in Hatfield

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 Hatfield: questions

Do you cover Hatfield?

Yes. Hatfield is part of the area we cover in Hertfordshire, including AL10, AL9 and AL7. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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.

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

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

How much is a visit in Hatfield?

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 Hatfield as elsewhere we cover.

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.

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.
