## Summary

The University of York has completed the tender process for its Deep Geothermal Drilling Works project, which forms part of its ambitious Sustainability Plan 2030 designed to achieve Net Zero. Situated in York, the project received substantial government funding from the Public Sector Decarbonisation Scheme to explore sustainable energy solutions via geothermal drilling. The awarded contract involves developing a deep geothermal doublet system on campus, consisting of wells more than 4km and 3km deep, to supply heat, thereby significantly reducing reliance on fossil fuels. The procurement process utilised a competitive flexible procedure and is now in the Award stage, with the contract slated to start on 27 February 2026 and continue until the end of 2027, with options to extend for further drilling activities conditional on additional funding. The project's value is estimated at £35,000,000 excluding VAT, with an upper potential of £42,000,000, reflecting grant-funded amounts and projected extensions.

This tender presents significant opportunities for businesses in the geothermal and renewable energy sectors, particularly those interested in sustainable innovation and infrastructure development. With the contract awarded to P R Marriott Drilling Limited, a large-scale drilling specialist, companies with capabilities in drilling equipment, geotechnical engineering, construction, and renewable energy solutions are positioned to benefit. The project encourages collaboration for turnkey solutions, advantageous for consortia and joint ventures that specialise in complex energy projects and site-specific engineering services. The University of York, with its significant focus on research and development, offers a rare partnership avenue for engineering firms to contribute to impactful climate action projects and establish a presence in the rapidly evolving sustainable energy market within the United Kingdom.

## Notice

In 2025 the University of York ("the Authority") launched an exciting deep geothermal energy project as a transformative step in its journey to Net Zero. The project aims to cut our fossil fuel consumption by 78% as part of our Sustainability Plan 2030 targets and making a substantial contribution to reducing the City of York's overall carbon footprint. This multi-phased initiative will leverage the Earth's natural heat to provide sustainable energy solutions for our campus and potentially the wider community. The project positions the University of York, City and region as a leader in sustainable energy innovation, combining geothermal exploration with our renowned research and educational expertise. Further details regarding the project can be found on the university website here https: //www.york.ac.uk/about/sustainability/campus-operations/climate-action/geothermalenergy/ The Authority has conducted a tender process to appoint a contractor to deliver a deep geothermal doublet system consisting of a production well of more than 4km, and an injector well of more than 3km, with the aim of extracting geothermal heat to supply the Authority's campus district heat network, thereby removing the need for CHP units in an effort to meet the university's net zero goals. This phase of the project was awarded funding from the government's Public Sector Decarbonisation Scheme in April 2025. The tender process has concluded, and a successful contractor selected to fully deliver the project, which shall involve the drilling and all associated activities. The project shall be delivered by the Authority and York University Energy Supply Company (YUESCo) which is the Authority's wholly owned subsidiary company responsible for the Authority's on-campus energy production and distribution. The Authority has sufficient funding in place to deliver the project, and is actively seeking additional funding (both internal and external) to potentially deliver a subsequent production well for research or other use. For clarity, the estimated total value stated in this notice is an estimate of maximum value covered by secured grant funds to deliver the initial two well project and ancillary projects (circ PS20,000,000 exVAT), and also an estimated value to deliver a subsequent third well should the Authority secure additional funds (circ PS15,000,000 exVAT).
