Skylight replacement for Porthcawl: the essentials
Skylight replacement in Porthcawl means replacing tired domes and failed glass with a modern rooflight. We cover the CF36 district and the rest of Mid Glamorgan, with a survey before any price is fixed.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Typical uses for skylight replacement include older extensions due a modern rooflight.
We work across Mid Glamorgan, including Porthcawl, and in neighbouring towns such as Bridgend and Port Talbot. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Roof window replacement in pitched roofs
- Misted glass unit replacement only
- Upstand rebuild and insulation
- Like-for-like size replacement
- Dome to flat glass upgrade
- Often reuses the existing opening
- Option to add opening and rain sensor
Before you order: points to check
- Old glass and domes are disposed of responsibly
- A replacement is a chance to meet current thermal standards
Planning and building rules for Porthcawl
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.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Questions about skylight replacement in Porthcawl
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.
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
Do I need to be at home for the survey in Porthcawl?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Porthcawl?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
