Skylight installation for Northallerton: the essentials
For Northallerton homes and buildings we offer skylight installation: survey, supply and fit — new openings, extensions and fit-only work. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Exposed Pennine and coastal towns in Yorkshire need upstand and flashing details built for wind-driven rain. Skylight installation suits builders' projects and retrofits into finished roofs.
From Northallerton to Darlington, Thornaby-on-Tees and Stockton-on-Tees, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Fit only (customer-supplied units)
- Internal plaster reveal
- Supply and fit
- Upstands and flashings
- Electrics coordination
- Free survey for new installations
- Fitting for builders on new extensions
Before you order: points to check
- Structural changes may need an engineer's check
- Building Regulations approval (a building warrant in Scotland) may be needed
Planning and building rules for Northallerton
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. 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.
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 Northallerton
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.
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.
How do I book a survey in Northallerton?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Is the survey in Northallerton free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
