Planning and building regulations in West 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.
Wales has its own householder permitted development rules; listed buildings and conservation areas are the usual cases needing consent.
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 West Glamorgan: questions
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.
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.
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.
Who checks building regulations for a lantern in West Glamorgan?
Your local authority building control team. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
