Skylight replacement in Battersea: what is involved?
We handle skylight replacement across Greater London, including Battersea. In short: replacing tired domes and failed glass with a modern rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Think of skylight replacement for yellowed domes, misted glass and leaking roof windows.
We work across Greater London, including Battersea, and in neighbouring towns such as Wandsworth and Chelsea. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Dome to flat glass upgrade
- Like-for-like size replacement
- Upstand rebuild and insulation
- Roof window replacement in pitched roofs
- Fixed to electric opening

- Clearer view and more light
What to check first
- Upstand and roof condition decide the scope
- Enlarging the opening changes the structure and may need approval
Do you need permission in Battersea?
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. 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.
