## Summary

NHS Blood and Transplant bought services to maintain its existing environmental monitoring systems. The requirement covers environmental monitoring activity other than monitoring associated with construction, with the stated scope focused on maintenance rather than installation of new systems. The work is associated with the buyer’s site at North Bristol Park in Filton, Bristol, and falls within the environmental monitoring services category (CPV 90711500). The procurement was suitable for small and medium-sized enterprises. The selected supplier, Contronics Limited, is based in Congleton and is classified as an SME. This requirement is relevant to businesses that maintain operational environmental monitoring equipment and systems for public-sector or healthcare sites.

This procurement has been completed and awarded. NHS Blood and Transplant used a selective call-off from a framework agreement, with bids due by 31 August 2026 at noon. The contract was awarded to Contronics Limited on 21 September 2026 for £236,436 including the stated GBP currency. The contract period runs from 1 October 2026 to 31 January 2027. The award is active. The opportunity was evaluated as a services requirement for maintenance of existing environmental monitoring systems. The published information identifies the procurement scope, framework call-off route, award outcome, supplier, value and contract dates, but does not set out further award criteria or separate lots beyond the stated maintenance requirement.

For a supplier that did not win this procurement, the award indicates a defined NHS demand for maintenance of existing environmental monitoring systems at a North Bristol site, delivered through a framework call-off route. Businesses best placed for a future requirement of this kind would be specialists in maintaining environmental monitoring systems already in operation, with the technical ability to support an established installation rather than provide a new-build monitoring solution. A credible competitor would also need to understand the operational demands of healthcare-related sites, work reliably within public-sector arrangements and demonstrate sufficient delivery capacity for a short, focused maintenance service. The buyer has identified SMEs as suitable, so specialist smaller firms can be relevant competitors.
