Summary of the contracting process

Nuclear Restoration Services Limited procured the manufacture of ventilation ductwork for the Prototype Fast Reactor ventilation upgrade. The requirement is primarily for ventilation ducting, with associated mechanical engineering installation works, classified under CPV 39563530 and CPV 45351000. It is a goods procurement supporting nuclear restoration and reactor ventilation infrastructure. Delivery and related activity are stated to take place in the United Kingdom. The buyer is a public authority based in Warrington. The requirement was structured as one lot and was identified as suitable for small and medium-sized enterprises, making it relevant to manufacturers and engineering businesses able to produce specialist ductwork for demanding industrial environments.

The procurement has been awarded and contracted following an open procedure. Six bids were received, including six from SMEs. The tender deadline was 11 May 2026 at 12:00, following an extension from 27 April; enquiries closed on 17 April and the award period ended on 19 May. Gow's Lybster Limited was awarded the contract on 20 July 2026. The awarded and signed contract value is £521,574.45 excluding VAT (£625,889.34 including VAT). The contract was signed on 17 August 2026 and runs from 17 August 2026 to 18 June 2027, with a possible maximum extent to 17 December 2027. Evaluation weighted technical ability at 60%, social value at 10% and price at 30%.

This award demonstrates demand from Nuclear Restoration Services for specialist ventilation ductwork manufacture supporting Prototype Fast Reactor infrastructure. A credible future competitor would need the capability to design or manufacture ventilation ducting to the required technical specification, manage fabrication and delivery in an industrial or nuclear-related setting, and coordinate effectively with the buyer's site operations. The evaluation shows that technical competence carried twice the weight of price, while social value was also assessed, so suppliers would need more than competitive pricing: they would need strong evidence of technical ability and a clear, deliverable social value offer. The successful supplier was an SME, indicating that businesses of similar scale can compete for this type of requirement.
