Skylight replacement in Ely: what is involved?
For Ely 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.
Coastal towns in the East of England see salty air, so we specify frame finishes and fixings with exposure in mind. Skylight replacement suits yellowed domes, misted glass and leaking roof windows.
We work across Cambridgeshire, including Ely, and in neighbouring towns such as Newmarket and March. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Fixed to electric opening
- Upstand rebuild and insulation
- Like-for-like size replacement
- Dome to flat glass upgrade
- Roof window replacement in pitched roofs
- Often reuses the existing opening
- Cures most chronic leaks
Before you order: points to check
- Enlarging the opening changes the structure and may need approval
- A replacement is a chance to meet current thermal standards
Do you need permission in Ely?
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.
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.
Read the planning permission guide before you commit to a design.
