## Summary

Guy's and St Thomas' NHS Foundation Trust has concluded a direct award procurement process for refurbishment and upgrade work on Air Handling Units (AHUs) and IAP ventilation systems at its London site. The project aims to address compliance, performance, and resilience risks identified in recent technical surveys, with CFES-Ltd being awarded the contract valued at approximately £160,296.15. The procurement, classified under 'works' and identified by the title "Refurbishment and upgrade work on Air Handling Units (AHUs) and IAP ventilation," followed a direct award method due to technical and operational considerations, as CFES Ltd is the existing provider. The contract period is scheduled from 2nd February 2026 to 30th April 2026, and the award has been noted as active on 16th January 2026.

This tender offers significant business growth opportunities, especially for enterprises specialising in HVAC system refurbishments and upgrades. CFES-Ltd's involvement underscores the need for businesses that have technical expertise and familiarity with bespoke and interdependent systems. While this procurement was not open to additional bidders due to the technical reasons specified, it exemplifies the prospects available to firms capable of managing complex, regulatory-compliant upgrades in critical health infrastructure. SMEs involved in hospital facilities maintenance and technical installations might find inspiration in the strategic alliances and pre-existing service provider roles that were pivotal in securing this contract.

## Notice

The procurement covers refurbishment and upgrade works to existing SSD AHUs and IAP ventilation systems to address compliance, performance, and resilience risks identified through recent technical surveys.

### Procurement Information

CFES Ltd is the incumbent provider responsible for the design, installation, and ongoing technical configuration of the existing SSD AHU and IAP ventilation systems across both Guy's and St Thomas' Hospital sites. The systems are bespoke, highly integrated, and interdependent with CFES-designed components, controls, and software. Engaging an alternative provider would introduce significant technical, clinical, and programme risk, including extended shutdown periods, system incompatibility, and potential non-compliance with HTM 03-01 requirements. For these reasons, no reasonable alternative supplier can deliver the required scope without material disruption to SSD operations.
