The Building Safety Act 2022 (BSA 2022) introduced fundamental reforms to the law and regulation of building safety, which seek to ‘secure the safety of people in or about buildings and improve the standard of buildings’. BSA 2022, Pts 3 and 4 provided the framework for a new regulatory system applicable to ‘higher-risk buildings’ (HRBs). BSA 2022, Pt 3 enabled the creation of a stringent building control regime that applies to the design and construction phase of HRBs. BSA 2022, Pt 4 imposed risk management and reporting obligations on those responsible for occupied HRBs. These measures are referred to, collectively, as the ‘HRB regime’. This Practice Note looks at BSA 2022, Pt 4 which contains provisions relating to the management of building safety risks in occupied HRBs in England. BSA 2022, Pt 4 does not apply to HRBs in Wales. For commentary on the Welsh position on HRBs, see Practice Note: Building and Fire Safety—the position in England, Scotland and Wales.
