What we fit in Kensington
From flat-roof extensions to period slate roofs, we fit the right rooflight for the building in Kensington — after a survey, with a fixed written price.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep.
From Kensington to Notting Hill, Shepherds Bush and Chelsea, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules in England
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
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. 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.

Skylight questions: Kensington
How do I book a survey in Kensington?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do you fit skylights and rooflights in Kensington?
Yes. We survey and fit skylights and rooflights in Kensington and across Greater London. Send your postcode and we will offer a survey date when we reply.
Will I need planning permission in Kensington?
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.
Can you work alongside my builder in Kensington?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Fixed or opening?
Opening units suit kitchens, bathrooms and bedrooms; fixed units are simpler and cheaper where the room already ventilates well.
Can a skylight be fitted into an existing flat roof?
Yes. We form the opening, trim joists, build an insulated upstand, re-waterproof and make good the ceiling.
