Summary of the contracting process

Nuclear Restoration Services Limited is procuring services to calibrate and maintain portable radiological instruments used across all NRS sites, including additional sites transferring from EDF’s advanced gas-cooled reactor programme. The requirement is primarily an engineering and instrument-calibration service, covering the continuing reliability and accuracy of radiological monitoring equipment. Delivery is across the United Kingdom. It is a single service requirement rather than a multi-lot procurement. Businesses with specialist capability in radiological instrumentation, calibration and maintenance are the most relevant potential suppliers. The work will support nuclear restoration operations, where dependable portable instruments are needed for radiological measurement and control across a geographically distributed estate.

The procurement has reached tender: NRS invited suppliers to submit offers through an open procedure. The enquiry deadline was 6 October 2026 at 12:00 BST, and the tender submission deadline is 3 November 2026 at 12:00 UTC. The award decision is due by 9 December 2026. The initial contract period runs from 1 April 2027 to 31 March 2031, with an option, at NRS’s discretion, to extend the arrangement to 31 March 2035, giving up to eight years in total. The estimated value is £19 million excluding VAT, or £22.8 million including VAT. Evaluation is based on technical quality (58%), commercial price (25%), social value (10%) and contract management (7%). Electronic submission is allowed in English.

This opportunity suits engineering and calibration businesses with practical experience of portable radiological instruments and the capability to maintain and calibrate them across multiple nuclear sites. Suppliers should be able to manage a technically demanding, safety-critical service covering equipment associated with radiological monitoring. The requirement is identified as suitable for small and medium-sized enterprises, so specialist firms may be able to compete alongside larger providers if they can demonstrate the necessary technical competence, service capacity and operational coverage. The strongest fit will be organisations able to provide consistent calibration and maintenance, coordinate work across the NRS estate and support additional sites transferred from EDF’s advanced gas-cooled reactor operations.
