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

You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.
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.

Rules that apply in Potters Bar

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 Potters Bar: questions

Do you cover Potters Bar?

Yes. Potters Bar is part of the area we cover in Hertfordshire, including EN6. 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.

How much is a visit in Potters Bar?

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 Potters Bar as elsewhere we cover.

Do you charge more for Potters Bar than other towns in Hertfordshire?

No. Guide prices are the same for Potters Bar as for anywhere else we cover in Hertfordshire. 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.

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.
