How we approach loft conversion skylights in Chelsea
Loft conversion skylights in Chelsea means roof windows planned for loft rooms — light, headroom and escape. We cover the SW10 district and the rest of Greater London, with a survey before any price is fixed.
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. Think of loft conversion skylights for attic bedrooms, offices and en-suites.
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, building control and Chelsea
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. 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. 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.

Can I add blinds later?
Yes — most manufacturers make blinds for each window size.

Can you work alongside my builder in Chelsea?
