How we approach conservation rooflights in Ystradgynlais
Our conservation rooflights service in Ystradgynlais covers slim, low-profile steel-look rooflights for period and listed roofs. 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. In Ystradgynlais, as anywhere, conservation rooflights are the usual choice for period, listed and conservation-area roofs.
Ystradgynlais is around 89 km from Newtown, and we survey and fit throughout that part of Powys, including the SA9 district.

Do you need permission in Ystradgynlais?
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.
See our building regulations guide for U-values, glazing limits and self-certification.
