Skylight replacement in Kilburn: what is involved?
For Kilburn homes and buildings we offer skylight replacement: replacing tired domes and failed glass with a modern rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Skylight replacement suits older extensions due a modern rooflight.
From Kilburn to Hampstead, Cricklewood and Highgate, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for skylight replacement in Kilburn
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.
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.

Skylight replacement in Kilburn: questions
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
Can you work alongside my builder in Kilburn?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Kilburn?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
