The requirement covers maintenance associated with PMOK WACS water-treatment systems, under the SBS10509 framework, Lot 4. It is classified as water-treatment work and falls within services. Delivery is in the West Hertfordshire area of the East of England, serving the Trust’s hospital operations. The named buying organisation is West Hertfordshire Teaching Hospitals NHS Trust. The requirement is focused on maintaining water-treatment infrastructure rather than supplying standalone equipment or undertaking general construction. Businesses active in planned, preventive or responsive maintenance of water-treatment systems for healthcare premises would find the subject matter relevant, particularly where they can operate across the Trust’s estate and meet the requirements of the framework route used for this procurement. The procurement is complete and has been awarded following a selective call-off from a framework agreement. The tender submission deadline was 16 June 2026 at 12:00. The estimated value was between £50,550 and £60,000, excluding any stated assumptions in the procurement documents. The contract was awarded to Proeconomy Limited on 24 June 2026 for £57,550. The contract period runs from 1 July 2026 to 30 June 2027. The opportunity was not identified as suitable for small or medium-sized enterprises or voluntary, community and social enterprises. Evaluation details are not set out in the available procurement data, but the selected supplier was appointed through the SBS10509 framework’s Lot 4 call-off process. This award demonstrates an NHS Trust’s demand for specialist maintenance of water-treatment systems supporting hospital operations, at a scale suited to an established service provider rather than a small standalone assignment. Future competitors would need demonstrable capability in water-treatment maintenance, including the operational capacity to support healthcare premises reliably and to manage planned service delivery across the relevant estate. Experience of maintaining systems where water quality, continuity of service and compliance are critical would strengthen credibility. Access to the relevant SBS10509 framework, particularly Lot 4, is important because this requirement was placed as a framework call-off rather than through an open tender. Suppliers should therefore assess framework participation, healthcare references and the ability to deliver responsive technical support in West Hertfordshire. ## Notice Contract for PMOK WACS Water Treatment Maintenance for WHTHT.
