Skylight replacement in Aylesbury: what is involved?
For Aylesbury homes and buildings we offer skylight replacement: replacing tired domes and failed glass with a modern rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
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 replacement include yellowed domes, misted glass and leaking roof windows.
From Aylesbury to Leighton Buzzard, Berkhamsted and Chesham, the same survey-first process applies: measure, specify, fix the price, then fit.

Do you need 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. 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.
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.

- Agree the quote. You approve the specification and price before anything is ordered.
- Installation day. Usually one day into a prepared opening, longer for new openings.
