UK2 - Preliminary Market Engagement Notice
Summary of the contracting process

Severn Trent Water Limited and Hafren Dyfrdwy Cyfyngedig intend to establish a framework for end-to-end capital design services across their operating areas in England and Wales. The work covers optioneering and feasibility studies, outline design, and detailed design through to coordinated, construction-ready designs. Service areas include water and waste networks, water and waste treatment processes, potable tanks and distribution service reservoirs, bioresources, and secondments. This is engineering design and engineering support work, classified under CPV 71320000 and 71336000. The framework is intended to support the authorities’ capital investment programmes and the development of efficient, sustainable schemes that meet regulatory and performance commitments.

This procurement is at the planning stage and is not yet an invitation to tender. The authorities expect to use a UK4 notice after preliminary market engagement, with a future notice date of 11 January 2027. A supplier engagement event is scheduled for 29 September 2026 at Cranmore Park Conference Centre, Shirley, and the engagement milestone is due by 9 October 2026. The expected procurement is a single-lot, closed framework under the utilities regime, with an estimated value of £200 million excluding VAT and £240 million including VAT. The proposed contract period is 1 November 2027 to 31 October 2031, with renewal possible to a maximum extent of 31 December 2035. The lot is marked as suitable for SMEs.

The work will suit engineering consultancies and design practices able to provide capital design capability from early option development through feasibility, outline and detailed design. The authorities are looking for suppliers with strong technical competence across the full design lifecycle, including the ability to cover water and waste networks, treatment processes, reservoirs, bioresources and related secondment services. Regulated water-sector experience is particularly relevant, as is the capacity to work across England and Wales and support a substantial, multi-year capital investment programme. Suppliers should be prepared to demonstrate a strong commitment to health and safety, sustainability, value optimisation, collaborative working and innovative scheme development. The planned market engagement is intended to test market capacity and appetite, inform lotting and process design, and identify ways to support SME participation.
