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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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.

Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do you fit skylights and rooflights in Blackburn?
Yes. We survey and fit skylights and rooflights in Blackburn and across Lancashire. Send your postcode and we will offer a survey date when we reply.
Is the survey in Blackburn free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will a rooflight make my room too hot?
It can on a south-facing roof with clear glass. Solar-control glass, an opening unit and a blind keep the room comfortable.
Can a skylight be fitted into an existing flat roof?
Yes. We form the opening, trim joists, build an insulated upstand, re-waterproof and make good the ceiling.
