Planning and building regulations for Gorseinon
Wales sets its own energy standards for rooflights in the Welsh Approved Document L, so the Welsh figures apply rather than England's.
Permitted development rules in Wales are set separately, so check with your council, especially for listed buildings and conservation areas.
Building regulations in Gorseinon 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 Gorseinon
Does a longer lantern need extra support?
Long lanterns use intermediate rafters inside the lantern itself. The roof structure around the opening must be designed to carry the lantern's weight; your builder or engineer sizes the trimmers.
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.
Do you deliver roof lanterns to Gorseinon?
Yes. Delivery to Gorseinon (SA4) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
Can you fit a roof lantern in Gorseinon?
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.
