Planning and building regulations in South Glamorgan
Rooflight energy standards in Wales come from the Welsh Approved Document L (2022), so check figures quoted for England do not get used by mistake.
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.

Flat rooflights in South Glamorgan: questions
Do flat rooflights leak?
They should not, provided they are installed on a properly flashed upstand with the right fall and the seals are maintained.
Can a flat rooflight open?
Some ranges offer electric opening versions. Ask for availability for your size.
Can I walk on a flat rooflight?
Only if it is a walk-on rooflight designed for foot traffic. Standard rooflights are not designed to be walked on.

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.
