Planning and building rules in England
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. 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.

- 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.
Do you charge for repair visits?
Yes, repairs are charged. We give the price before the visit.
Why is my skylight leaking?
Common causes are a failed seal, a membrane that has split or lifted at the upstand, a low upstand, blocked drainage or condensation mistaken for a leak.
Can you fix a misted rooflight?
A misted unit means the glass seal has failed. The sealed unit, or the whole rooflight, needs replacing.
Will I need planning permission in Lancashire?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof.
