The work covers monitoring, testing and technical analysis of pumping and aeration systems and associated equipment, with the aim of reducing whole-life costs, improving energy efficiency and optimising performance. The anticipated delivery model includes site identification and data collection, mobilisation and stakeholder engagement, efficiency and control studies, approval for testing, site-based testing and performance monitoring, outcome review and business-case validation, followed by handover to engineering or capital-delivery teams. Services will be delivered across Thames Water’s operational sites in the Thames Valley, London and the Home Counties. The requirement is classified as services, including energy-management, energy-efficiency consultancy, technical analysis, inspection and testing. The programme is expected to involve about 200 tests across 60 operational sites. The procurement has reached tender: Thames Water invited suppliers to submit a Pre-Selection Questionnaire through SAP Ariba under a selective, competitive flexible procedure. Suppliers passing selection will be invited to the Invitation to Negotiate stage, with initial tenders, possible clarifications, negotiations and presentations before final evaluation. This is a single-lot, sole-supplier framework, with call-offs awarded directly without reopening competition. The published tender and lot value is £0 GBP. Enquiries close on 12 October 2026 at 17:00, and requests for PSQ access and PSQ submissions close on 19 October 2026 at 12:00. The intended award period ends on 2 May 2027 at 23:59. The contract is scheduled from 10 May 2027 to 9 May 2030, with extensions potentially taking it to 9 May 2035. Technical quality and commercial cost each carry 50% of the evaluation weighting. This opportunity suits specialist pump, aeration, energy-efficiency, engineering analysis and technical testing providers, including SMEs. Suppliers need to cover the Thames Valley, London and Home Counties and demonstrate the capacity to work across multiple operational sites and a substantial programme of testing. Thames Water is looking for a proven record of delivering measurable savings and innovation in pump optimisation, aeration efficiency or closely related services. Strong candidates will be able to collect and analyse operational data, conduct efficiency and control studies, undertake site-based testing and monitoring, validate business cases, and support engineering handover. The framework also requires collaborative working, stakeholder engagement, continuous improvement, KPI reporting and strategic partnership over the contract lifecycle. Suppliers must demonstrate suitable legal and financial capacity and hold, or commit to obtaining, specified insurance cover: £15m public liability, £15m products liability, £10m professional indemnity and £5m third-party property damage. ## Notice IMPORTANT: Please read this section before deciding whether you wish to register for this event.
