Planning and building regulations in Gwent
Wales sets its own energy standards for rooflights in the Welsh Approved Document L, so the Welsh figures apply rather than England's.
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.

Roof lantern upstands in Gwent: questions
Do I need an upstand for a roof lantern?
Yes. Lanterns are designed to sit on an upstand, never directly on the roof deck.
Who makes the upstand weatherproof?
Your roofer, by dressing the roof membrane up the outside of the upstand. The lantern then sits over it.
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.
How quickly can I get a roof lantern in Gwent?
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 Gwent.
