What we fit in Caerphilly
We survey, supply and fit skylights and rooflights in Caerphilly and the CF83 district — flat rooflights, roof lanterns, roof windows, walk-on glass, sun tunnels and commercial rooflights.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting.
Caerphilly sits about 9 km from Risca and 9 km from Pontypridd, and we cover the whole CF83 postcode district and the roads in between.

Planning and building rules in Wales
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. 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.

Skylight questions: Caerphilly
Will I need planning permission in Caerphilly?
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.
How do I book a survey in Caerphilly?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Caerphilly?
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 Caerphilly?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will a rooflight make my room too hot?
It can on a south-facing roof with clear glass. Solar-control glass, an opening unit and a blind keep the room comfortable.
Do you take a deposit?
Nothing is paid until you accept a written quote. Made-to-measure products are ordered after you accept, we tell you in writing when the order is placed, and the quote states the payment stages.
