Conservation rooflights in Llanelli: what is involved?
Conservation rooflights in Llanelli means slim, low-profile steel-look rooflights for period and listed roofs. We cover the SA15 district and the rest of Dyfed, 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 Llanelli, as anywhere, conservation rooflights are the usual choice for slate and plain-tile roofs where a quiet roofline matters.
Llanelli is the main town we list in Dyfed; we also cover nearby Gorseinon and Swansea.

Planning and building rules for Llanelli
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.
