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 potential impact of of deep geothermal heat on long term energy security.

In 2023, the Department co-funded a study with the Northeast Local Enterprise Partnership on the UK’s deep geothermal potential. Further research on the levelised costs of geothermal heat and power was published in summer 2025. Based on this evidence, the British Geological Survey was commissioned to develop the UK Geothermal Platform—an open-access, web-based tool which launched in 2025 to help developers and investors identify geothermal opportunities and conduct pre-feasibility assessments.
