How we approach flat rooflights in Briton Ferry
Our flat rooflights service in Briton Ferry covers fixed double or triple glazed rooflights for flat roofs and extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. In Briton Ferry, as anywhere, flat rooflights are the usual choice for kitchen extensions, side returns and flat-roofed back rooms.
From Briton Ferry to Neath, Port Talbot and Swansea, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Briton Ferry
- Solar-control or self-cleaning outer pane
- Double or triple glazing
- Integral or fitted blinds
- Plastered or lined internal reveal
- Frame colours: anthracite, black, white or RAL
- Inner pane laminated for safety overhead
- Even, top-down daylight across the whole room
Things we check at survey
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
Planning, building control and Briton Ferry
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.

Common questions
How long does it take?
Fitting into a prepared upstand usually takes a day. Forming a new opening in an existing roof, including making good inside, is often two to three days.
Double or triple glazing?
Double glazing suits most domestic jobs. Triple glazing improves thermal performance and cuts noise from rain, which is worth it over bedrooms or where the energy calculation is tight.
Can you fit into my existing flat roof?
Yes. We form a new opening, trim the joists, build and waterproof an upstand and make good the ceiling. A survey confirms the joist direction and roof build-up first.
Will I need planning permission in Briton Ferry?
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.
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.
