Pitched roof windows for Wandsworth: the essentials
For Wandsworth homes and buildings we offer pitched roof windows: centre-pivot and top-hung skylights for tiled and slate roofs. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
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. Typical uses for pitched roof windows include lofts, attic rooms, landings and vaulted ceilings.
We work across Greater London, including Wandsworth, and in neighbouring towns such as Battersea and Chelsea. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Combination and stacked windows
- Centre-pivot or top-hung
- Flashings for tiles, slates or recessed fitting
- Integral blinds and shutters
- Manual, electric or solar-powered opening

- Flashings to suit tiles or slates
What to check first
- Front-facing roof windows can need permission in conservation areas
- Rafters may need trimming for wider windows
Planning and building rules for Wandsworth
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. 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.

Pitched roof windows in Wandsworth: questions
Can roof windows be electric?
Yes — electric and solar-powered models open by remote and many include rain sensors.
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 you work alongside my builder in Wandsworth?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Wandsworth?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
