Planning and building regulations for Swansea
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.
Permitted development rules in Wales are set separately, so check with your council, especially for listed buildings and conservation areas.
Building regulations in Swansea 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.

Questions from Swansea
My old lantern leaks. Is it the lantern or the roof?
Often the roof or kerb detailing. A survey or close inspection will tell. If the lantern is the problem, replacing it is usually better value than repairing old polycarbonate.
Will a new lantern be warmer?
A modern double glazed lantern with a thermally broken frame loses far less heat than polycarbonate.
