How we approach skylight installation in Willesden
Skylight installation in Willesden means survey, supply and fit — new openings, extensions and fit-only work. We cover the NW10 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. Skylight installation suits builders' projects and retrofits into finished roofs.
We work across Greater London, including Willesden, and in neighbouring towns such as Cricklewood and Notting Hill. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Willesden
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.

Common questions
Do you fit rooflights bought elsewhere?
Yes. We check the product and the opening first, and our workmanship terms cover the fitting rather than the product.
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
How long does installation take?
Fitting into a prepared upstand takes about a day. A new opening in an existing roof, including making good, often takes two to three days.
