Skylight installation for Barry: the essentials
Skylight installation in Barry means survey, supply and fit — new openings, extensions and fit-only work. We cover the CF62 district and the rest of South Glamorgan, with a survey before any price is fixed.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. In Barry, as anywhere, skylight installation is the usual choice for new extensions, new openings and fit-only jobs.
Neighbouring towns include Dinas Powys (6 km) and Penarth (9 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Barry
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. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
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.
Read the planning permission guide before you commit to a design.

How the job runs
- Send the details. Postcode, rough size and a photo of the roof and room.
- Survey. We measure the opening, check the roof build-up and agree the options.
- Fixed quote. Product, work and price in writing — nothing is ordered until you agree.
- Fit and make good. We fit, seal, test and finish the reveal, then hand over the paperwork.

Common questions
Do you fit rooflights bought elsewhere?
Yes. We check the product and the opening first, and our workmanship terms cover the fitting rather than the product.
Who handles building control?
We tell you which route applies — building control approval, a building warrant in Scotland, or in England and Wales self-certification by a registered competent person — and supply the product data.
Do I need a structural engineer?
For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.
Is the survey in Barry free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
