Skylight replacement in Briton Ferry: what is involved?
For Briton Ferry 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 Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Typical uses for skylight replacement include older extensions due a modern rooflight.
Briton Ferry is around 9 km from Swansea, and we survey and fit throughout that part of West Glamorgan, including the SA11 district.
Specification options
- Dome to flat glass upgrade
- Like-for-like size replacement
- Upstand rebuild and insulation
- Roof window replacement in pitched roofs
- Fixed to electric opening
- Usually done in a day
- Cures most chronic leaks
Before you order: points to check
- Old glass and domes are disposed of responsibly
- Enlarging the opening changes the structure and may need approval
Planning, building control and Briton Ferry
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
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.
Read the planning permission guide before you commit to a design.

Common questions
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
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 Briton Ferry?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Briton Ferry?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
