## Summary

The Countess of Chester Hospital NHS Foundation Trust procured works to replace critical air-handling unit (AHU) plant serving a ward at its hospital in Chester. The requirement falls within repair and maintenance of plant, covering the physical replacement of critical ventilation or air-treatment equipment rather than a general facilities-management service. The buyer is the NHS foundation trust based on Liverpool Road, Chester. The work was delivered at the hospital’s Chester site. The procurement comprised a single requirement covering the AHU plant replacement. It is relevant to mechanical engineering, building-services and healthcare estates contractors with experience of replacing or maintaining critical air-handling equipment in operational hospital or other controlled environments.

The procurement is complete and was awarded to Senate Mech Limited, a small or medium-sized enterprise. The Trust used a direct award below the applicable threshold without competition. The contract was signed on 12 August 2026 and ran from 13 to 14 August 2026. Its value was £10,000 excluding VAT, or £12,000 including VAT. The award covered the single AHU plant replacement requirement and is recorded as active. The process was evaluated through the direct-award route rather than a competitive tender, so no comparative tender evaluation basis is stated. The outcome demonstrates a short-duration, below-threshold hospital engineering works contract delivered by a named specialist supplier.

For competing suppliers, this award shows demand for rapid, specialist mechanical works involving critical AHU plant in an NHS hospital ward. Credible providers would need the technical capability to remove and replace air-handling equipment, plan work around a clinical environment, and restore ventilation systems safely within a tightly controlled delivery window. Relevant experience in healthcare estates, critical ventilation, plant-room access, isolation procedures and commissioning would strengthen a future response. Suppliers should also be able to manage a small, focused works package directly with an NHS estates or facilities team, maintain appropriate health-and-safety controls, and demonstrate reliable delivery of essential plant repairs or replacements without disrupting patient services.
