Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the adequacy of safety regulations for battery energy storage sites.

In GB, battery fires are rare and are mitigated by a robust framework overseen by the Health and Safety Executive, requiring responsible parties to ensure safety throughout a battery’s deployment. 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.
