Skylight installation in Barnes: what is involved?
Skylight installation in Barnes means survey, supply and fit — new openings, extensions and fit-only work. We cover the SW13 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. Think of skylight installation for builders' projects and retrofits into finished roofs.
Barnes sits about 2 km from Chiswick and 3 km from Putney, and we cover the whole SW13 postcode district and the roads in between.

Planning and building rules for Barnes
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. 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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.
