Sun tunnels & tubular skylights for Gorseinon: the essentials
We handle sun tunnels & tubular skylights across West Glamorgan, including Gorseinon. In short: light pipes that bring daylight to halls and bathrooms with no window. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Sun tunnels & tubular skylights suit windowless hallways, landings and bathrooms.
Gorseinon is around 9 km from Swansea, and we survey and fit throughout that part of West Glamorgan, including the SA4 district.

Planning, building control and Gorseinon
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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.
