Skylight installation in Southall: what is involved?
We handle skylight installation across Greater London, including Southall. In short: survey, supply and fit — new openings, extensions and fit-only work. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
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. Typical uses for skylight installation include new extensions, new openings and fit-only jobs.
Southall is around 17 km from central London, and we survey and fit throughout that part of Greater London, including the UB1 district.

Planning and building rules for Southall
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. 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.
Read the planning permission guide before you commit to a design.

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 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.
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
How do I book a survey in Southall?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Is the survey in Southall free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
