UK2 - Preliminary Market Engagement Notice
Summary of the contracting process

The UK Atomic Energy Authority is buying a set of 21 identical optical fibre bundles for an upgrade to the MAST-U Thomson scattering diagnostic. The requirement covers the manufacture and delivery of horizontally bifurcated optical fibre bundles, with every bundle following the same design. This is a goods contract in the diagnostic-device category (CPV 33124100), intended for use in the UK. The opportunity is relevant to specialist manufacturers of optical fibre assemblies, diagnostic equipment or related scientific instrumentation. It may also suit businesses able to produce repeatable, technically consistent components for research and fusion facilities, provided they can meet the specified design and delivery requirements.

The procurement reached tender: the UK Atomic Energy Authority invited offers through a below-threshold open competition. It is a single-lot requirement. The enquiry deadline was 27 July 2026 at 11:00 UTC, and the tender submission deadline was 6 August 2026 at 16:00 UTC. Electronic submission was allowed. The contract period runs from 1 September 2026 to 31 January 2027. The estimated value is £120,000 excluding VAT, or £144,000 including VAT. Offers are evaluated primarily on quality, weighted at 80%, with price weighted at 20%. This means technical compliance, manufacturing approach and the ability to deliver the required identical assemblies are likely to carry substantially more weight than lowest cost alone.

This opportunity suits small and medium-sized enterprises, as well as specialist engineering businesses with the facilities and technical control needed to manufacture identical optical fibre bundles. Strong candidates are likely to have experience in optical fibre assembly, bifurcated or branched fibre components, diagnostic instrumentation, or comparable scientific hardware. The work calls for consistent production across a complete set rather than one-off fabrication, so suppliers should be able to demonstrate repeatable manufacturing, inspection and quality-control processes. Businesses serving fusion research, plasma diagnostics, laboratories or advanced engineering markets may find the application particularly relevant. No specific accreditation is stated, so the main commercial fit is a proven ability to interpret a technical design, manufacture to it consistently and coordinate delivery.
