Conservation rooflights for Wandsworth: the essentials
For Wandsworth homes and buildings we offer conservation rooflights: slim, low-profile steel-look rooflights for period and listed roofs. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
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.
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.
What you can choose
- Blinds
- Steel or aluminium frames
- Toughened or laminated double glazing
- Flashings for slate or plain tile
- Central vertical glazing bar
- Steel or aluminium frame in black or grey
- Optional central glazing bar
Things we check at survey
- Conservation officers may specify size and position
- Listed building consent is needed for listed buildings
Do you need permission in Wandsworth?
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. 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. 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.
