Summary of the contracting process

Nuclear Restoration Services Limited is procuring specialist services to calibrate and maintain radiological instruments installed from 2027 onwards. The requirement covers all NRS sites, including additional sites transferring from EDF under the AGR programme. This is an engineering and instrument-calibration service rather than a supply-only contract, involving the continuing technical support needed to keep radiological measurement equipment accurate and fit for use. Delivery is required across NRS sites in the United Kingdom. The procurement is suitable for small and medium-sized enterprises. The buyer is Nuclear Restoration Services Limited, a public authority responsible for nuclear restoration activities. Suppliers whose work includes radiological instrumentation, calibration programmes, engineering support and maintenance of safety-critical equipment are likely to find the scope relevant.

The procurement has reached tender: the buyer invited offers through an open procedure. It is a single-lot service contract, with bids due by 3 November 2026 at 12:00 UTC and enquiries due by 6 October 2026 at 12:00 BST. The evaluation 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 to 31 March 2035, giving a potential total duration of eight years. The estimated value is £18.5 million excluding VAT, or £22.2 million including VAT. Evaluation is weighted 58% technical, 10% social value, 7% contract management and 25% commercial. Electronic submission in English is allowed.

This opportunity suits businesses able to provide ongoing calibration and maintenance of radiological instruments across multiple nuclear sites. Relevant suppliers are likely to have established engineering teams, specialist knowledge of radiological measurement equipment and the operational capacity to deliver planned and responsive maintenance over a multi-year programme. Experience coordinating work across a geographically distributed site network would be useful, particularly as the scope includes sites transferring from EDF. The evaluation gives greatest weight to the technical proposal, so suppliers should be able to demonstrate a credible technical delivery model and the competence to maintain instrument reliability. Contract management capability is assessed separately, while social value commitments also form part of the competition. The requirement is explicitly suitable for SMEs, including firms that can deliver specialist services directly or through a capable delivery partnership.
