Skylight installation for Thornton-Cleveleys: the essentials
Thinking about skylight installation in Thornton-Cleveleys? The short answer: survey, supply and fit — new openings, extensions and fit-only work. The longer answer depends on your roof, which is why we survey before we price.
Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. In Thornton-Cleveleys, as anywhere, skylight installation is the usual choice for builders' projects and retrofits into finished roofs.
We work across Lancashire, including Thornton-Cleveleys, and in neighbouring towns such as Fleetwood and Blackpool. Access, parking and how the glass reaches the roof are all checked at the survey.

Consents for skylight installation in Thornton-Cleveleys
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.

Skylight installation in Thornton-Cleveleys: questions
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
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.
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.
Will I need planning permission in Thornton-Cleveleys?
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.
Is the survey in Thornton-Cleveleys free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
