Rules that apply in England

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.

Questions about safety edge and photocell repairs in Hertfordshire

Can I get a price without anyone visiting?

Yes. The guide price tool takes four steps and gives a range for your opening and door type, or the visit price for a repair. It is a guide, not a quote: the written quote comes after the survey or once the visit price is agreed.

How do I book a visit in Hertfordshire?

Tell us what the door is doing using the form on this page, by phone or on WhatsApp. We confirm the visit price before anyone comes out, then confirm the date in writing.

Which towns do you cover in Hertfordshire?

We cover Hertfordshire, including Watford, Hemel Hempstead, Stevenage and St Albans. Every town has its own page with local details, and you can start a guide price for any postcode in Hertfordshire online.

Do you repair safety devices on any make of roller door?

Yes. We repair and replace safety edges and photocells on electric roller garage doors of any make, provided compatible parts are available for the control box. We don't work on sectional or up-and-over doors. If a compatible part isn't available, we'll explain the options before anything is booked.

Can photocells be added to a door that doesn't have them?

Often, if the control box has a connection for them. 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 photocells can be added, and the price, before booking. Our battery backup and safety upgrades page covers adding devices.
