Planning and building regulations in Dyfed
Wales sets its own energy standards for rooflights in the Welsh Approved Document L, so the Welsh figures apply rather than England's.
Check the Welsh permitted development rules with your council before ordering, particularly in conservation areas.
Building regulations are checked by your local authority building control team. Replacing a rooflight in an existing home is building work in Wales too. A competent person scheme installer can self-certify; otherwise building control should be notified.

Rectangular roof lanterns in Dyfed: questions
What is the most common rectangular roof lantern size?
Sizes of 1000 × 2000 mm and 1500 × 2500 mm are common standard sizes for kitchen and dining extensions, but the right size is the one that matches your kerb. If your kerb is not built yet, our sizes guide helps you pick a standard size first.
Can a rectangular lantern be made to an exact size?
Yes. Made-to-measure lanterns are built to the external kerb size you give us, usually in 10 mm steps within the range's limits. Made-to-measure takes longer than a stock size and cannot be cancelled once ordered, so measure twice.
Which way should the ridge run?
The ridge runs along the longer side. On a square opening there is no ridge and the lantern becomes a pyramid.
Do I need planning permission for a roof lantern in Dyfed?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your county or county borough council before ordering.
