What do conservation rooflights in Clapham involve?
We handle conservation rooflights across Greater London, including Clapham. In short: slim, low-profile steel-look rooflights for period and listed roofs. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
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. Conservation rooflights suit period, listed and conservation-area roofs.
Clapham sits about 2 km from Balham and 2 km from Battersea, and we cover the whole SW4 postcode district and the roads in between.
Options we can specify in Clapham
- Toughened or laminated double glazing
- Steel or aluminium frames
- Manual or electric opening

What to check first

- Listed building consent is needed for listed buildings
Do you need permission in Clapham?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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. 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.
