How we approach skylight installation in Derby
We handle skylight installation across Derbyshire, including Derby. 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.
Industrial and commercial units around Midlands towns often still have their original rooflight sheets, which are due for replacement. Typical uses for skylight installation include builders' projects and retrofits into finished roofs.
Derby is the main town we list in Derbyshire; we also cover nearby Belper and Ilkeston.

Consents for skylight installation in Derby
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 Derby
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.
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.
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.
Is the survey in Derby free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
