Skylight installation for Hayes: the essentials
Our skylight installation service in Hayes covers survey, supply and fit — new openings, extensions and fit-only work. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Typical uses for skylight installation include builders' projects and retrofits into finished roofs.
From Hayes to Southall, Greenford and Northolt, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for skylight installation in Hayes
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.

Do you work with builders?

Can you work alongside my builder in Hayes?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
