What does skylight installation in Kingston upon Thames involve?
Skylight installation in Kingston upon Thames means survey, supply and fit — new openings, extensions and fit-only work. We cover the KT1 district and the rest of Greater London, with a survey before any price is fixed.
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 builders' projects and retrofits into finished roofs.
Kingston upon Thames is around 15 km from central London, and we survey and fit throughout that part of Greater London, including the KT1 district.

Planning, building control and Kingston upon Thames
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. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.

Questions about skylight installation in Kingston upon Thames
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.
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 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.
Is the survey in Kingston upon Thames free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Kingston upon Thames?
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.
