Planning and building regulations in Llandrindod Wells
Before anything is built in Llandrindod Wells, we confirm which approvals apply in Wales. In Wales drawings are prepared to suit the council’s validation requirements and Welsh building regulations.
Building regulations in Wales are set by the Welsh Government. Approval comes from the council’s building control service or a registered building control approver, with inspections during the work and a completion certificate at the end.
We check this for your address before design work starts, so there are no surprises later.
