Skylight installation for Altrincham: the essentials
Skylight installation in Altrincham means survey, supply and fit — new openings, extensions and fit-only work. We cover the WA14 district and the rest of Greater Manchester, with a survey before any price is fixed.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. Think of skylight installation for builders' projects and retrofits into finished roofs.
From Altrincham to Sale, Urmston and Stretford, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for skylight installation in Altrincham
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.

Questions about skylight installation in Altrincham
Is the survey free?
Yes, for new installations. Repair visits are charged.
Who handles building control?
We tell you which route applies — building control approval, a building warrant in Scotland, or in England and Wales self-certification by a registered competent person — and supply the product data.
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.
Will I need planning permission in Altrincham?
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.
Can you work alongside my builder in Altrincham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
