How we approach skylight installation in Cheltenham
We handle skylight installation across Gloucestershire, including Cheltenham. 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.
Stone cottages, slate roofs and conservation areas are common in the South West, and conservation-profile rooflights keep the roofline quiet. Typical uses for skylight installation include new extensions, new openings and fit-only jobs.
Jobs in Cheltenham 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 Cheltenham?
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. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
Read the planning permission guide before you commit to a design.

Skylight installation in Cheltenham: 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.
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 a structural engineer?
For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.
How do I book a survey in Cheltenham?
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 Cheltenham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
