How we approach skylight installation in Beckenham
Skylight installation in Beckenham means survey, supply and fit — new openings, extensions and fit-only work. We cover the BR3 district and the rest of Greater London, with a survey before any price is fixed.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Skylight installation suits builders' projects and retrofits into finished roofs.
Beckenham sits about 3 km from Bromley and 4 km from Catford, and we cover the whole BR3 postcode district and the roads in between.

Planning, building control and Beckenham
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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.
