Skylight installation for Abergavenny: the essentials
Our skylight installation service in Abergavenny covers survey, supply and fit — new openings, extensions and fit-only work. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Think of skylight installation for builders' projects and retrofits into finished roofs.
Abergavenny sits about 13 km from Pontypool and 14 km from Ebbw Vale, and we cover the whole NP7 postcode district and the roads in between.

Consents for skylight installation in Abergavenny
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.
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.

Questions about skylight installation in Abergavenny
How long does installation take?
Fitting into a prepared upstand takes about a day. A new opening in an existing roof, including making good, often takes two to three days.
Is the survey free?
Yes, for new installations. Repair visits are charged.
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.
Will I need planning permission in Abergavenny?
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 I need to be at home for the survey in Abergavenny?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
