Loft conversion skylights for Llanelli: the essentials
Loft conversion skylights in Llanelli means roof windows planned for loft rooms — light, headroom and escape. We cover the SA15 district and the rest of Dyfed, with a survey before any price is fixed.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Think of loft conversion skylights for attic bedrooms, offices and en-suites.
Llanelli is the main town we list in Dyfed; we also cover nearby Gorseinon and Swansea.

Do you need permission in 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.
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.
