## Summary

Cambridge University Hospitals NHS Foundation Trust procured airborne particle monitoring services using portable particle counters. The requirement concerns monitoring particles in the air, with delivery in the Cambridge area. The award is classified as a service and relates to a single lot. The buyer is the NHS foundation trust; Clean Air Technologies Limited was selected to provide the service. This is a specialist environmental monitoring requirement for a healthcare organisation, rather than a general supply of equipment: the procurement title identifies portable particle counters, while the awarded item is described as airborne particle monitoring. Suppliers working in particle monitoring and related clean-air services are the closest fit.

The procurement is complete and the award is active. Cambridge University Hospitals NHS Foundation Trust awarded the single-lot contract to Clean Air Technologies Limited. The contract was signed on 7 September 2026 and runs from 7 October 2026 to 6 October 2027. Its value is £24,825 excluding VAT (£29,790 including VAT). The process was described as below threshold, with no further procedure detail. The published procurement information does not set out evaluation criteria or eligibility requirements, so the award basis cannot be characterised beyond the stated procurement details.

This award shows demand from Cambridge University Hospitals for airborne particle monitoring delivered using portable particle counters. A credible competitor for a comparable requirement would need to provide particle-monitoring services and the relevant portable counter capability, with the practical capacity to serve a hospital trust in the Cambridge area. Clean Air Technologies Limited, an SME, secured the award, showing that a smaller specialist supplier competed successfully for this below-threshold requirement. Suppliers with directly relevant monitoring experience and an ability to deliver the service in a healthcare setting are best aligned with the demonstrated requirement. The contract period indicates the timeframe of the current service arrangement; the award is useful evidence of the buyer's purchasing need, not an invitation to compete for this contract.
