Planning and building regulations for Cardiff
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 in Cardiff 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 Cardiff
Can I replace polycarbonate panels with glass?
Usually not in the old frame: glass is much heavier than polycarbonate and the frame was not designed for it. Replacing the whole lantern is the safer route.
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.
Can you fit a roof lantern in Cardiff?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
Is it worth having solar-control glass in Cardiff?
With the midsummer sun about 62.0° high at noon, roof glass in Cardiff gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
