Skylight replacement in High Wycombe: what is involved?
For High Wycombe 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. In High Wycombe, as anywhere, skylight replacement is the usual choice for yellowed domes, misted glass and leaking roof windows.
High Wycombe sits about 10 km from Amersham and 12 km from Maidenhead, and we cover the whole HP13 postcode district and the roads in between.
What you can choose
- Like-for-like size replacement
- Dome to flat glass upgrade
- Misted glass unit replacement only
- Fixed to electric opening
- Upstand rebuild and insulation
- Cures most chronic leaks
- Often reuses the existing opening
Things we check at survey
- Upstand and roof condition decide the scope
- A replacement is a chance to meet current thermal standards
Planning and building rules for High Wycombe
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about skylight replacement in High Wycombe
Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
Do I need building regulations approval to replace a rooflight?
Replacements in existing homes generally need to meet current thermal standards and may need notification or approval. We advise on the route for your job.
How do I book a survey in High Wycombe?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in High Wycombe?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
