The Fire Safety (England) Regulations 2022 implemented the majority of the recommendations made by the Grenfell Tower Inquiry in its Phase 1 report which required a change in the law.
The regulations seek to improve the fire safety of blocks of flats in ways which are practical, cost-effective for individual leaseholders and proportionate to the risk of fire.
The regulations came into force on 23 January 2023.
