Summary of the contracting process

Southern Water Services Limited is seeking continuous water-quality monitoring services to meet requirements under the Environment Act 2021. The work combines data services with pollution-monitoring equipment and detection and analysis apparatus (CPV 72300000). The requirement is for monitoring across locations in Worthing and other parts of southern England, including Hampshire, the Isle of Wight, Surrey and Sussex. This is a utility-sector services contract, structured as a single requirement rather than separate lots. Suppliers should consider whether they can provide an integrated monitoring service, including the equipment and data capability needed to gather and analyse water-quality information over a geographically spread operating area.

Southern Water invited offers through a competitive flexible procedure using a selective procurement method. The process reached the tender stage, with expressions of interest and enquiries due by 9 November 2026 at 14:00. The buyer expected to complete the award process by 25 March 2027. The contract period is 4 May 2027 to 5 May 2037, with an option for a further five years, potentially extending the term to 6 May 2042. The estimated contract value is £130.5 million excluding VAT (£156.6 million including VAT). Quality accounts for 70% of the evaluation and price for 30%. The procurement is arranged as a closed framework agreement with one participant and no reopening of competition.

This opportunity is suited to suppliers able to deliver continuous water-quality monitoring as a long-term utility service, combining monitoring devices with reliable data collection, processing and analysis. The geographical spread means providers need the operational capacity to install, maintain and support equipment across multiple locations in southern England, and to sustain monitoring and reporting over a substantial contract term. The evaluation places greater weight on quality than price, so businesses with strong technical performance, dependable service delivery and demonstrable water-monitoring expertise are well placed to compete. The lot is marked as suitable for small and medium-sized enterprises, making it relevant to specialist providers as well as larger integrated suppliers. No particular accreditation or prior-experience threshold is stated in the procurement details.
