BGS releases second version of the UK geothermal catalogue
#image_title
The British Geological Survey has released an updated version of the UK geothermal catalogue with nearly 14,000 new data points.
The British Geological Survey (BGS) has released the second version of the UK geothermal catalogue, which adds nearly 14,000 more data points derived from 800 sites to inform geothermal assessments. The digital release contains validated intellectual property rights and datasets from BGS-authored papers, new BGS thermal conductivity laboratory measurements and a bottom-hole temperature dataset from the UK Onshore Geophysical Library.
First launched in 2025 (following an earlier version in 2024), the UK Geothermal Platform provides national to local-scale information on geothermal potential across shallow and deep technology options.
The platform draws together diverse information and synthesizes it to deliver the information needed by heat policy, heat networks, the national zoning model and planning specialists. Towns, cities and industrial sites can be assessed for the potential to retrofit geothermal technology and new development zones can be quickly assessed for strategic use of geothermal energy from the start of the development or planning cycle.
“The open release of the second digital version of the UK geothermal catalogue further adds to over 90 datasets and more than 60 reports that have been available on the UK Geothermal Platform since August 2025. The data informs the feasibility stages of project developments, supporting the growth of the geothermal energy sector. The user guide describes the data sources and the acknowledged limitations with legacy datasets that are included,” said Dr Alison Monaghan, head of BGS Geothermal.
