UK2 - Preliminary Market Engagement Notice
Summary of the contracting process

South East Water Limited is planning a successor framework for network maintenance services and network capital works across the South East of England. The anticipated scope covers water-main renewals and strategic mains, repair and maintenance of the water supply network, and network installation for developers. Work is intended to support customer service and outcomes, regulatory targets, Outcome Delivery Incentives, leakage reduction and Price Control Deliverables. Relevant activities include water-main refurbishment, pipelaying, construction of water and sewage pipelines, water-distribution pipeline works and water-meter repair and maintenance. The procurement is categorised as services and is being developed under the utilities regime. It is intended to replace South East Water’s existing Network Maintenance and Capital Works Framework Agreement.

This procurement is at the planning stage and is currently an early market engagement exercise, not an invitation to tender or a commitment to procure. South East Water expects to use a framework agreement, with the final scope, lotting structure, delivery model and commercial arrangements to be informed by market feedback. The buyer expects to hold a supplier webinar on 1 October 2026 from 2pm to 3pm and issue a questionnaire about capability, capacity, market appetite, commercial preferences and innovation. The anticipated contract period is 1 April 2028 to 31 March 2038, a possible 10-year term. Estimated annual spend is £110 million to £135 million. The estimated total value is £1.35 billion excluding VAT and £1.62 billion including VAT.

The engagement will suit contractors and service providers with substantial experience maintaining and expanding treated-water distribution networks. Relevant preparation should include capability in water-main renewal, strategic mains, network repair and maintenance, developer connections, pipelaying, pipeline construction, water-main refurbishment and water-meter maintenance. Suppliers should be able to demonstrate the operational capacity to support a large, long-term programme and deliver safely across the South East of England. The buyer is seeking views on efficient delivery models, innovation, collaboration and customer outcomes, so businesses with evidence of improving leakage performance, meeting regulatory targets, supporting Outcome Delivery Incentives or delivering Price Control Deliverables should prepare relevant examples. Participation is intended to help shape the future framework rather than secure work at this stage.
