In GB, fires at battery sites are rare and are mitigated by a regulatory framework overseen by the Health and Safety Executive. The latest available 5-year annual average fire incidence rate for GB batteries is 0.7% (2020/21 to 2024 to 2025)[1], lower than for wider non-domestic building fires in England at 0.8% (2019/20 to 2023/24)[2].

To complement this regulation, DEFRA is consulting on including batteries within the Environmental Permitting Regulations (EPR). EPR requires sites to demonstrate to the Environment Agency that harms are avoided or controlled and provides for ongoing regulatory inspections.
