Planning and building regulations in West Glamorgan
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 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.

Roof lantern upstands in West Glamorgan: questions
What height should my upstand be?
High enough to keep water away from the lantern seal, commonly at least 150 mm above the finished roof surface. Follow the instructions for your chosen range.
Do I need an upstand for a roof lantern?
Yes. Lanterns are designed to sit on an upstand, never directly on the roof deck.
Can I order a lantern before the upstand is built?
Yes, if you build the upstand to the lantern's stated external size. Many people order the lantern and upstand together so they match.
How quickly can I get a roof lantern in West Glamorgan?
Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for West Glamorgan.
