Skylights and rooflights across Mid Glamorgan
SkylightCompany.uk covers the whole of Mid 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
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.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.

Common questions
Do you cover all of Mid Glamorgan?
Yes. We survey and fit across Mid Glamorgan, including Rhondda, Tonypandy and Bridgend. Remote and island addresses are by arrangement.
Do I need planning permission for a rooflight in Mid Glamorgan?
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.
Do you supply only, or fit too?
We supply and fit. We also fit rooflights you have already bought, after checking the product and the opening.
How do I get a price?
Use the guide-price tool for an instant range, or send the form with your postcode and a photo for a fixed quote after survey.
Can a skylight be fitted into an existing flat roof?
Yes. We form the opening, trim joists, build an insulated upstand, re-waterproof and make good the ceiling.
