What is a planning or building regulations application?
Planning permission decides whether a project can be built; building regulations decide how it must be built. Most extensions, lofts and conversions need building regulations approval even when planning permission is not required.

Planning and building regulations in Swansea
Approvals for a planning or building regulations application in Swansea follow the rules for Wales. In Wales applications go to the local planning authority, and building control can be the council or a registered building control approver.
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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
