How we approach bespoke & shaped rooflights in Chelsea
We handle bespoke & shaped rooflights across Greater London, including Chelsea. In short: triangular, angled, curved and multi-pane rooflights made to measure. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
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. In Chelsea, as anywhere, bespoke & shaped rooflights are the usual choice for angled ceilings, corners and architect-designed extensions.
From Chelsea to Battersea, Wandsworth and Kensington, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for Chelsea
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Questions about bespoke & shaped rooflights in Chelsea
Can bespoke units open?
Some can. Shaped glass is usually fixed, combined with a standard opening unit elsewhere.
Will a shaped rooflight leak more?
Not if detailed properly — corners and junctions just need more care.
Can any shape be made?
Most straight-edged shapes can be made in glass, within the manufacturer's size and angle limits. Curved glass is possible but specialist.

Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
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.
