Summary of the contracting process

UK Fusion Energy Ltd procured the detailed design and build of a Compound Cryogenic Pump Prototype (CCPP). The work involves developing the detailed design from existing preliminary design documentation, then building the prototype. It covers engineering design services and the supply and integration of pump equipment, including compound cryogenic, vacuum and air-pumping functions. This is a specialist engineering and manufacturing requirement rather than routine equipment supply. The procurement is led by UK Fusion Energy Ltd, based at Culham Science Centre in Abingdon, for delivery in the United Kingdom. Suppliers operating across cryogenic engineering, vacuum technology, pump and compressor manufacture, prototype development, mechanical design and build, or complex equipment integration may find the requirement relevant.

The procurement has been awarded following a completed above-threshold open procedure. Two bids were received and both reached the final stage. RI Research Instruments GmbH was awarded the single lot on 11 March 2026 for £1,500,000 excluding VAT (£1,800,000 including VAT). The award contract period was 9 April 2026 to 30 September 2028, while the signed active contract runs from 12 August 2026 to 12 February 2029. The contract was signed on 11 August 2026. Responses were due by 4 February 2026 at 12:00, following an extension, and the enquiry period ended on 27 January 2026. Evaluation weighted technical quality at 55%, commercial considerations at 35% and social value at 10%. The lot was identified as suitable for SMEs.

This award demonstrates demand from UK Fusion Energy Ltd for a substantial, technically led prototype engineering package combining design completion, cryogenic pump development and physical build. A credible future competitor would need demonstrable expertise in cryogenic systems, vacuum and air pumps, engineering design, prototype manufacture and the integration of complex mechanical equipment. The evaluation weighting shows that technical capability carries greater importance than price, so suppliers should be able to evidence robust design assurance, engineering problem-solving and the ability to turn preliminary designs into a functioning prototype. The requirement is suitable for SMEs, but delivery would still require sufficient engineering, manufacturing, project-management and quality capacity to manage a specialist build for a public fusion-energy organisation. Social-value delivery should also be incorporated into the offer.
