Skylight installation for Grangemouth: the essentials
Skylight installation in Grangemouth means survey, supply and fit — new openings, extensions and fit-only work. We cover the FK3 district and the rest of the Forth Valley, with a survey before any price is fixed.
Many Scottish homes have dormers and attic rooms where an extra roof window adds light without a full dormer. Typical uses for skylight installation include builders' projects and retrofits into finished roofs.
Jobs in Grangemouth are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Do you need permission in Grangemouth?
In Scotland most rooflights on houses fall under Class 2B permitted development; in a conservation area, or on a listed building, consent is needed. Flats and tenements are outside householder permitted development, so check with the planning authority first.
Under the Scottish building standards, replacement rooflights should average 1.6 W/m²K or better, and no individual unit should exceed 3.3 W/m²K. Replacing a rooflight, frame included, does not need a building warrant, but the work must still meet the building standards.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
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.
Will I need planning permission in Grangemouth?
Planning rules in Scotland differ: rooflights are treated as external alterations under Class 2B, with no permitted development in conservation areas.
Is the survey in Grangemouth free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
