Planning and building rules in England
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
Do you repair roof windows too?
Yes — flashings, seals, hinges and glass on pitched roof windows.
Is it condensation or a leak?
Condensation forms on the inside face on cold days and comes back in the same pattern. A leak appears when it rains and often tracks down the reveal.
Can you repair an electric rooflight that will not open?
Often, yes — actuators, controllers and rain sensors can be replaced if parts are available.
Do you charge for repair visits?
Yes, repairs are charged. We give the price before the visit.
Will I need planning permission in Cheshire?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge.
