How we approach loft conversion skylights in Cowbridge
Thinking about loft conversion skylights in Cowbridge? The short answer: roof windows planned for loft rooms — light, headroom and escape. The longer answer depends on your roof, which is why we survey before we price.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. In Cowbridge, as anywhere, loft conversion skylights are the usual choice for loft conversions and rooms in the roof.
We work across South Glamorgan, including Cowbridge, and in neighbouring towns such as Llantwit Major and Bridgend. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for Cowbridge
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. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
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. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
See our building regulations guide for U-values, glazing limits and self-certification.
