Skylight installation in Nailsea: what is involved?
Skylight installation in Nailsea means survey, supply and fit — new openings, extensions and fit-only work. We cover the BS48 district and the rest of Somerset, with a survey before any price is fixed.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Skylight installation suits builders' projects and retrofits into finished roofs.
Nailsea sits about 6 km from Portishead and 7 km from Clevedon, and we cover the whole BS48 postcode district and the roads in between.

Planning, building control and Nailsea
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. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
