Skylight installation in Frome: what is involved?
Thinking about skylight installation in Frome? The short answer: survey, supply and fit — new openings, extensions and fit-only work. The longer answer depends on your roof, which is why we survey before we price.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Typical uses for skylight installation include builders' projects and retrofits into finished roofs.
Frome sits about 10 km from Warminster and 13 km from Trowbridge, and we cover the whole BA11 postcode district and the roads in between.
Specification options
- Upstands and flashings
- New openings with joist trimming
- Electrics coordination
- Fit only (customer-supplied units)

What to check first
- Structural changes may need an engineer's check
- Fit-only work relies on the product being suitable and complete
Do you need permission in Frome?
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. 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.
