Skylight installation in Gloucestershire: the essentials
Across Gloucestershire, our skylight installation work covers survey, supply and fit — new openings, extensions and fit-only work. Survey first, fixed price second, fitting third.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty.

Planning and building rules in England
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. 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.
Guide prices
These are typical supply-and-fit ranges. For an address in Gloucestershire, scaffold, a hoist for heavy glass, or a new structural opening can move the figure, which is why we survey first.
| Option | Guide price inc VAT | Ex VAT |
|---|---|---|
| New opening in an existing roof, supply and fit | £2,395 – £5,395 | £1,995 – £4,495 |
| Supply and fit into a new extension Typical | £1,435 – £3,595 | £1,195 – £2,995 |
| Fit only, customer-supplied unit | £595 – £1,195 | £495 – £995 |
How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common 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.
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 work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
Will I need planning permission in Gloucestershire?
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.
