What does skylight replacement in Cowbridge involve?
Skylight replacement in Cowbridge means replacing tired domes and failed glass with a modern rooflight. We cover the CF71 district and the rest of South Glamorgan, with a survey before any price is fixed.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Think of skylight replacement for older extensions due a modern rooflight.
Cowbridge sits about 6 km from Llantwit Major and 11 km from Bridgend, and we cover the whole CF71 postcode district and the roads in between.

Planning, building control and Cowbridge
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. 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. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Do I need to be at home for the survey in Cowbridge?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Cowbridge?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
