Skylight installation for Sheffield: the essentials
We handle skylight installation across South Yorkshire, including Sheffield. 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.
Many Yorkshire homes have had kitchen extensions with flat roofs, where a larger glass rooflight is a straightforward upgrade from an old dome. In Sheffield, as anywhere, skylight installation is the usual choice for builders' projects and retrofits into finished roofs.
We cover all of Sheffield and the S1 district, and nearby Rotherham and Dronfield.

Planning and building rules for Sheffield
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. 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.

Skylight installation in Sheffield: questions
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 work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
Do I need to be at home for the survey in Sheffield?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Sheffield?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
