The Fire Safety (England) Regulations 2022 were placed on the statute book on 18 May 2022, and came into force on 23 January 2023. The regulations implement the majority of those recommendations made to government in the Grenfell Tower Inquiry Phase 1 report which require a change in the law.
Responsible Persons, including both building owners (for example freeholders) and other persons having control of the premises (for example managing agents) are required to comply with the regulations from 23 January 2023. Any breach of the regulations is a criminal offence if the breach places one or more relevant persons (for example residents, staff or visitors) at risk of death or serious injury in the event of fire.
