Skylight installation in Falmouth: what is involved?
Skylight installation in Falmouth means survey, supply and fit — new openings, extensions and fit-only work. We cover the TR11 district and the rest of Cornwall, with a survey before any price is fixed.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. Typical uses for skylight installation include builders' projects and retrofits into finished roofs.
Falmouth is around 12 km from Truro, and we survey and fit throughout that part of Cornwall, including the TR11 district.

Planning, building control and Falmouth
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. 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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
