## Summary

Nuclear Restoration Services Limited, through its Dounreay operation, procured calibration, servicing and repair of liquid scintillation counters. This is a specialist equipment-maintenance service for counters used to measure radioactivity in liquid samples. The work is for the buyer’s Dounreay requirement in Scotland. The service category is calibration and repair of laboratory measurement equipment (CPV 50433000).

The procurement is complete and the contract was awarded to Isocount UK Limited. NRS used a direct award without competition, below the applicable threshold. The contract was signed on 25 September 2026 and runs from 1 October 2026 to 30 September 2029. Its gross value is £180,623.40 (£150,519.50 excluding tax). There was one lot, covering calibration, servicing and repair of the counters. The published information does not describe a competitive evaluation or award criteria; the supplier was selected through the direct-award route.

For suppliers considering similar future work for Nuclear Restoration Services, this award indicates demand for specialist support of liquid scintillation counters at Dounreay. A credible competitor would need the technical ability to calibrate, service and repair this type of radiation-measurement equipment, along with the capacity to provide ongoing support across a multi-year service arrangement. Experience maintaining laboratory instruments used in radiological or nuclear environments would be relevant to demonstrating fit with the requirement. The buyer awarded the work directly without competition, so this process does not establish a competitive scoring model or specific qualification thresholds for future requirements.
