About building control approver
Most building work, from extensions and loft conversions to new homes and conversions, has to be checked against the Building Regulations. In England and Wales you can usually choose who does that: your council’s building control team, or a private registered building control approver. Either way, the check needs to be arranged before work starts.
Getting signed off in England
In England, your council’s building control team or a registered building control approver checks the work. They issue a completion or final certificate once they have the reports they need, such as the as-built SAP, EPC, air test and any sound or ventilation test results.
