What do pitched roof windows in Chelsea involve?
Thinking about pitched roof windows in Chelsea? The short answer: centre-pivot and top-hung skylights for tiled and slate roofs. The longer answer depends on your roof, which is why we survey before we price.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. In Chelsea, as anywhere, pitched roof windows are the usual choice for lofts, attic rooms, landings and vaulted ceilings.
Chelsea sits about 2 km from Battersea and 2 km from Wandsworth, and we cover the whole SW10 postcode district and the roads in between.

Planning and building rules for Chelsea
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. 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.
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.
Read the planning permission guide before you commit to a design.

Questions about pitched roof windows in Chelsea
Do I need planning permission for a roof window?
Often not, under householder permitted development, provided it does not project too far above the roof plane and conditions are met. Listed buildings, flats and some conservation areas are different. Our planning guide covers each nation.
Centre-pivot or top-hung?
Centre-pivot windows are easy to clean and suit most rooms. Top-hung windows open out from the top for an unobstructed view and suit lower roof pitches near eye level.
Can roof windows be electric?
Yes — electric and solar-powered models open by remote and many include rain sensors.
Do I need to be at home for the survey in Chelsea?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Chelsea?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
