Planning and building rules in Wales
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. 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. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Skylight questions: Cardiff
Do you fit skylights and rooflights in Cardiff?
Yes. We survey and fit skylights and rooflights in Cardiff and across South Glamorgan. Send your postcode and we will offer a survey date when we reply.
Will I need planning permission in Cardiff?
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.
Is the survey in Cardiff free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Cardiff?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Will a rooflight make my room too hot?
It can on a south-facing roof with clear glass. Solar-control glass, an opening unit and a blind keep the room comfortable.
Can I cancel?
Made-to-measure products are excluded from the statutory 14-day cancellation right, but you can cancel without charge until we place the order with the manufacturer. Our terms explain the rest.
