Planning and building regulations for Carmarthen
In Wales, the Welsh Government's own Approved Document L applies, with limiting values that are not the same as England's.
Check the Welsh permitted development rules with your council before ordering, particularly in conservation areas.
Building regulations in Carmarthen 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 Carmarthen
Do bespoke lanterns cost much more?
For simple rectangles the premium over a stock size is usually modest. Special shapes cost more because each one is engineered individually.
How accurate do my measurements need to be?
Accurate to the millimetre on the outside of the kerb, measured at several points. Kerbs are rarely perfectly square, so measure both diagonals too. Our measuring guide shows how.
Do I need planning permission for a roof lantern in Carmarthen?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your county or county borough council before ordering.
Who checks building regulations for a lantern in Carmarthen?
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.
