The new regulatory regime for the landmark Building Safety Act (BSA) comes into force on 1 October 2023 and will apply to all projects subject to Building Regulations apart from some excluded minor works. Some small practices whose work is limited to domestic projects (as well as small projects) had assumed that the act would not materially affect the way they work, as they have no involvement with ‘higher-risk buildings’ that will be subject to a number of new regulatory obligations, such as gateway approvals by the new Building Safety Regulator. This is not the case. New dutyholder roles for clients, designers, Principal Designers, contractors and Principal Contractors – including a requirement that designers should be competent to take on any design work they are contracted to deliver – will apply to domestic projects as well. This means that all practices have to prepare for the new regime that arrives, at the time of writing, in two weeks’ time.
