Skylight replacement for Bridgend: the essentials
We handle skylight replacement across Mid Glamorgan, including Bridgend. In short: replacing tired domes and failed glass with a modern rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Typical uses for skylight replacement include yellowed domes, misted glass and leaking roof windows.
We work across Mid Glamorgan, including Bridgend, and in neighbouring towns such as Porthcawl and Cowbridge. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Like-for-like size replacement
- Upstand rebuild and insulation
- Fixed to electric opening
- Dome to flat glass upgrade
- Roof window replacement in pitched roofs
- Better thermal performance
- Clearer view and more light
Things we check at survey
- Upstand and roof condition decide the scope
- Old glass and domes are disposed of responsibly
Do you need permission in Bridgend?
Planning rules in Wales are tighter than in England for rooflights: Class C rights do not apply in conservation areas, National Parks or AONBs, so a rooflight there needs planning permission. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
Welsh Building Regulations expect new or replacement rooflights to reach 2.2 W/m²K and roof windows 1.4 W/m²K or a Band B rating. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.
See our building regulations guide for U-values, glazing limits and self-certification.

Skylight replacement in Bridgend: questions
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
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.
Can you work alongside my builder in Bridgend?
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 Bridgend?
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites.
