On-construction EPC in Wales
49 providers offering on-construction EPC in or across Wales, including national firms. The rules in Wales differ from England’s, so see the notes below.
The rules in Wales
The process is the same as in England. Wales shares England’s EPC register, and the as-built report is the Welsh BRWL rather than BREL, with photographic evidence of how key details were built.

Getting signed off in Wales
Building control in Wales works much like England. Your council or a registered building control approver checks the work and issues a completion or final certificate. Wales has its own Approved Documents, and all new and converted homes must have sprinklers.
