If your home or building was built or last altered before 2000, it may contain asbestos. Before any work that disturbs the fabric of the building, a refurbishment and demolition asbestos survey is needed to find out where it is and how to deal with it safely.
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.
