How we approach pitched roof windows in Ystradgynlais
For Ystradgynlais homes and buildings we offer pitched roof windows: centre-pivot and top-hung skylights for tiled and slate roofs. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Typical uses for pitched roof windows include lofts, attic rooms, landings and vaulted ceilings.
From Ystradgynlais to Pontardawe, Neath and Briton Ferry, the same survey-first process applies: measure, specify, fix the price, then fit.

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.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Common questions
Will it need building regulations approval?
Fitting a new roof window usually involves cutting rafters and changing the thermal envelope, so building control approval (or, in England and Wales, a competent-person route) is normally needed. We tell you which applies.
Can a roof window be fitted from inside?
In most cases, yes — only the tiles around the opening are lifted, and much of the work is done from inside the loft.
Can roof windows be electric?
Yes — electric and solar-powered models open by remote and many include rain sensors.
Is the survey in Ystradgynlais free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
