What does skylight installation in Wembley involve?
Thinking about skylight installation in Wembley? The short answer: survey, supply and fit — new openings, extensions and fit-only work. The longer answer depends on your roof, which is why we survey before we price.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Think of skylight installation for new extensions, new openings and fit-only jobs.
We work across Greater London, including Wembley, and in neighbouring towns such as Harrow and Greenford. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for Wembley
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Common questions
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.
Do I need a structural engineer?
For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.
Can you work alongside my builder in Wembley?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do you offer skylight installation in Wembley?
Yes. We carry out skylight installation in Wembley and across Greater London. Send your postcode and we will offer a survey date when we reply.
