Rooflights for Swansea homes and buildings
We survey, supply and fit skylights and rooflights in Swansea and the SA1 district — flat rooflights, roof lanterns, roof windows, walk-on glass, sun tunnels and commercial rooflights.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere.
Swansea is the main town we list in West Glamorgan; we also cover nearby Briton Ferry and Gorseinon.

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.
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. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.

Skylight questions: Swansea
How do I book a survey in Swansea?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Is the survey in Swansea free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Swansea?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do you fit skylights and rooflights in Swansea?
Yes. We survey and fit skylights and rooflights in Swansea and across West Glamorgan. Send your postcode and we will offer a survey date when we reply.
Can I cancel?
Made-to-measure products are excluded from the statutory 14-day cancellation right, but you can cancel without charge until we place the order with the manufacturer. Our terms explain the rest.
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.
