How we approach skylight installation in Highgate
Skylight installation in Highgate means survey, supply and fit — new openings, extensions and fit-only work. We cover the N6 district and the rest of Greater London, with a survey before any price is fixed.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Skylight installation suits new extensions, new openings and fit-only jobs.
Highgate sits about 2 km from Hampstead and 3 km from Kilburn, and we cover the whole N6 postcode district and the roads in between.

Consents for skylight installation in Highgate
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.
