Rules that apply in England
The HSE Approved Code of Practice L8 and HSG274 set out how duty holders must assess and control Legionella risk. Hot water should be stored at 60°C and distributed at 50°C or above, with cold water below 20°C. In England, fire safety in non-domestic premises falls under the Regulatory Reform (Fire Safety) Order 2005, workplaces have had to separate recycling under Simpler Recycling since 31 March 2025, and the Building Safety Act 2022 adds duties for higher-risk residential buildings.
