## Summary

UK Research & Innovation (UKRI) bought a bespoke replacement pair of one-metre-long polarising supermirror V-cavities for the Larmor beamline at the ISIS Neutron and Muon Source. These precision scientific instruments support the beamline’s ongoing operation. The requirement is specialist laboratory and optical equipment, rather than general-purpose supplies. The procurement concerns the replacement components as a pair; no wider installation or maintenance service is described.

The procurement is complete and was awarded to SwissNeutronics AG. UKRI used a direct award below the applicable threshold, without competition. The contract was signed on 8 October 2026 and runs from 8 October 2026 to 16 March 2027. Its value is £70,480 excluding VAT (£84,576 including VAT). The procurement was a single lot for the replacement polariser pair. No separate award date or evaluation criteria are stated in the published details.

For suppliers competing for a similar requirement from UKRI, credibility would depend on the ability to design and supply bespoke, one-metre polarising supermirror V-cavities for a neutron-science beamline. The buyer’s selection of a specialist optics supplier indicates demand for precision components tailored to the Larmor beamline and suitable for its continuing operation. Relevant suppliers are those able to deliver this specific scientific equipment, rather than providers of general laboratory consumables or unrelated beamline services. The award was made directly without competition, so this outcome does not demonstrate a competitive evaluation or identify scored technical, price or qualification criteria.

## Notice

A replacement pair of bespoke 1m long polarising supermirror v-cavities are required for the ongoing operation of the Larmor beamline at the ISIS neutron and muon source.
