This page lists acoustic consultants covering all 22 Welsh local authority areas, with cities such as Cardiff, Swansea, Newport and Wrexham. Each of the 22 councils is the planning authority for its area, and Wales sets its own planning policy, so check the rules for Wales rather than England.

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.
