Skylight installation in Aylesbury: what is involved?
We handle skylight installation across Buckinghamshire, including Aylesbury. 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.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Typical uses for skylight installation include new extensions, new openings and fit-only jobs.
From Aylesbury to Leighton Buzzard, Berkhamsted and Chesham, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- New openings with joist trimming
- Fit only (customer-supplied units)
- Electrics coordination
- Upstands and flashings
- Supply and fit
- Free survey for new installations
- Fixed price in writing before work
What to check first
- Work at height is planned with suitable access
- Structural changes may need an engineer's check
Planning, building control and Aylesbury
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. 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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Questions about skylight installation in Aylesbury
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 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.
Is the survey free?
Yes, for new installations. Repair visits are charged.
Can you work alongside my builder in Aylesbury?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in Aylesbury?
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.
