## Summary

UK Research & Innovation is seeking a single supplier for magnetic-bearing drive systems for ISIS neutron disc choppers. The requirement is for specialist machinery: an initial purchase of between six and eleven disc-chopper drive systems, with later systems based on the same specification but adjusted to individual project requirements agreed at preliminary design review. The procurement covers one lot. Further purchases may be made during the contract, with an anticipated overall volume of around 20 systems, although that volume is not guaranteed. UKRI is the buying organisation. The systems’ delivery location is not stated in the procurement details.

The process reached tender: UKRI invited offers through an open procedure. The tender set 12 October 2026 at 14:00 for enquiries and 19 October 2026 at 14:00 for bid submission; the stated award decision date is 23 October 2026. The contract period is 9 November 2026 to 8 November 2030. The estimated value is £2.1 million excluding VAT (£2.52 million including VAT). There is one lot and one supplier is sought. Evaluation gives quality a 70% weighting and price 30%. The buyer may purchase further systems under the contract; the anticipated total volume is around 20, but is not guaranteed.

This requirement is most relevant to suppliers with specialist engineering capability in magnetic-bearing drive systems and equipment for neutron-scattering disc choppers. Suppliers need to be able to deliver an initial batch of multiple systems and adapt later systems to project-specific requirements agreed at preliminary design review. The procurement is identified as suitable for small and medium-sized businesses, and the anticipated demand across the contract could provide scope for repeat orders. The buyer seeks a single supplier, so bidders should be equipped to take responsibility for the full requirement. The published details do not set out particular accreditations or prior-experience thresholds.

## Notice

This tender provides the outline specification for UKRI to contract with a single supplier to supply between six- and eleven-disc chopper drive systems to be purchased within the first year of the call-off contract. Future systems procured under this contract would be based upon this specification, but adjusted to meet the specific project requirements, to be agreed at the project's preliminary design review. The total volume purchased throughout the duration of the contract is likely to be in the region of 20 systems, but this figure cannot be guaranteed.
