Tender Notice
Summary of the contracting process

Sellafield Ltd is leading a collaborative procurement for the detailed design, manufacture, testing, supply and delivery of high-efficiency particulate air (HEPA) filters. The filters will be used in radioactive and/or toxic atmospheric-air or inert-gas handling systems, so the requirement is aimed at specialist manufacturers and suppliers of safety-critical air-filtration equipment rather than general industrial filter distributors. The participating operating companies are Sellafield Ltd, NWS (Magnox) and NWS (Dounreay). This is a goods supply requirement, classified as air filters (CPV 42514310). Delivery is associated with Sellafield in Cumbria, postal area CA20 1PG, and the wider North West of England. The buyer is Sellafield Ltd.

The procurement has reached tender: the buyer invited offers using a selective competitive procedure with negotiation, above the applicable threshold. Bids were to be submitted by 27 October 2026 at 12:00 UTC. The planned contract period runs from 1 July 2027 to 30 June 2032. The total estimated procurement value is £6.8 million. The requirement is presented as a collaborative purchase for the three named NDA operating companies. It is suitable for small and medium-sized enterprises. Suppliers should expect a negotiated competition for a long-term supply arrangement covering the specified HEPA filters and associated design, manufacturing, testing and delivery activities.

This opportunity suits a specialist HEPA-filter manufacturer or an experienced engineering supplier able to manage the full product lifecycle, from detailed design through manufacture, testing, delivery and technical assurance. Relevant capability includes producing high-efficiency filtration equipment for radioactive or toxic environments, inert-gas systems and other safety-critical applications. Bidders will need dependable manufacturing capacity, rigorous quality control, traceable testing and the ability to meet demanding technical and operational requirements across multiple nuclear operating companies. Experience supplying equipment for hazardous-process, nuclear, containment or similarly regulated environments would place a supplier well. The stated SME suitability also makes this relevant to smaller specialist manufacturers, provided they can demonstrate the necessary technical competence, production resources and delivery reliability.
