What does skylight installation in Windsor involve?
Skylight installation in Windsor means survey, supply and fit — new openings, extensions and fit-only work. We cover the SL4 district and the rest of Berkshire, with a survey before any price is fixed.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Typical uses for skylight installation include new extensions, new openings and fit-only jobs.
Jobs in Windsor 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.
Options we can specify in Windsor
- Fit only (customer-supplied units)
- New openings with joist trimming
- Supply and fit
- Upstands and flashings
- Internal plaster reveal
- Fitting for builders on new extensions
- Fit-only for units you have bought
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, building control and Windsor
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Skylight installation in Windsor: 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 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 do I book a survey in Windsor?
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 Windsor free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
