## Summary

The United Kingdom National Nuclear Laboratory Limited bought two aerosol spectrometers for laboratory particle analysis. The instruments are intended to characterise particles associated with the laboratory’s SL DF determination of MSSS and PFCS experimental work. This is a supply contract for laboratory and precision equipment. Delivery is in the United Kingdom; the specific delivery site is not identified in the procurement information. The requirement concerns equipment supply rather than a broader laboratory service or works project.

The procurement is complete and a contract has been awarded to Filter Integrity Limited. The laboratory used a direct award below the applicable threshold, without competition; the procurement was arranged as one lot. The award date was not reported. The contract was signed on 6 October 2026, with a stated period from 12 October 2026 to 11 April 2027 and an optional six-month extension, subject to a latest end date of 10 September 2027. The contract value is £67,850 excluding VAT, or £81,420 including VAT. The stated requirement is for two aerosol spectrometers; no separate evaluation criteria are reported.

This award shows the National Nuclear Laboratory’s demand for specialist aerosol spectrometers to support experimental work characterising particles. Suppliers best placed to compete when this equipment requirement next reaches the market would need to supply instruments suitable for particle measurement in a nuclear laboratory research setting, and demonstrate that their equipment can support the specified analytical work. Credibility is likely to depend on specialist laboratory instrumentation capability and the ability to supply two instruments as a single requirement. Filter Integrity Limited, a small or medium-sized supplier, secured the contract through a direct award without competition, so this outcome does not establish competitive evaluation criteria or a broader supplier qualification profile.
