Skylight replacement for Didcot: the essentials
For Didcot 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.
Jobs in Didcot 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.

- Upstand rebuild and insulation
- Like-for-like size replacement
- Misted glass unit replacement only
- Fixed to electric opening
- Dome to flat glass upgrade
- Usually done in a day

What to check first
- Old glass and domes are disposed of responsibly
- Upstand and roof condition decide the scope
Planning and building rules for Didcot
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.
