Answer
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.
