Skylights and rooflights across West Glamorgan
SkylightCompany.uk covers the whole of West Glamorgan — homes, extensions, schools and commercial roofs — with a free survey for new installations.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen.

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

Do I need planning permission for a rooflight in West Glamorgan?
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.
Do you work on commercial buildings?

What guarantees do I get?
Products carry the manufacturer's own warranty, which we pass to you with the product data. Our workmanship terms are set out in the quote.
Do I need planning permission?
Usually not for a rooflight on a house within the permitted development limits. Rules differ by nation: flats are not covered, listed buildings need listed building consent, and in Wales, Scotland and NI a rooflight in a conservation area needs permission. See our planning guide.
