## Summary

Nuclear Restoration Services Limited, through its Dounreay site, commissioned engineering services for modifications to the bolts on an R74 flask. The work is a focused engineering task relating to flask equipment, rather than a broad engineering support service. The procurement was organised as one lot, with the requirement awarded to a single supplier. The buyer is Nuclear Restoration Services Limited, the organisation responsible for the Dounreay site. This opportunity is relevant to engineering firms with experience modifying specialist equipment and delivering technical work for nuclear restoration or similarly safety-sensitive environments.

The procurement is complete and the contract has been awarded to M5Tec Limited. Nuclear Restoration Services used a limited competition below the applicable threshold. The award was for engineering services under a single lot. The contract was signed on 25 September 2026 and runs from 25 September 2026 to 19 February 2027. Its stated value is £59,218.55 excluding VAT (£71,062.26 including VAT). The buyer described the procurement as competitive. No evaluation criteria are reported in the published process information.

This award shows demand at Dounreay for specialist engineering modifications to flask equipment, delivered through a small, single-lot contract. M5Tec Limited, an SME, was selected, showing that a smaller engineering supplier was able to undertake the requirement. A credible competitor for a future requirement of this kind would need the engineering capability to assess and modify flask bolts, along with the technical discipline to work on equipment used in a nuclear restoration setting. Relevant experience in specialist mechanical modifications and the capacity to complete a defined, site-related engineering task would be commercially pertinent. The evidence here is specific to R74 flask bolt modifications; it does not establish wider requirements for other engineering services.
