Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what analysis his Department has undertaken of the geographic suitability of locations in the UK for investment in geothermal energy; and what potential has been identified for such investment in (a) the UK, (b) the Midlands and (c) Broxtowe.

The Department has undertaken analysis through the UK Geothermal Platform and the “UK Geothermal Energy Review and Cost Estimations” (2025). The Platform provides national mapping of geothermal suitability and supports early-stage investment decisions. The Review finds that geothermal can provide reliable, low carbon heat and power, but projects typically involve high upfront capital costs and outcomes vary depending on local geology. Across the UK, including the Midlands and Broxtowe, there is potential for investment; however, viability depends on site-specific conditions and detailed feasibility assessments.
