Major Projects Framework AMP8/9

Thames Water Utilities Limited has established the Major Projects Framework, solicitation number FA2280, to support the development and delivery of significant water and wastewater capital projects across its operational area. Primarily designed for Asset Management Period 8 (AMP8), the framework also allows for continued use during AMP9 subject to specific terms and approvals. This arrangement provides a structured route for awarding project-specific contracts that encompass pre-construction services, engineering, construction, associated works, and the procurement of necessary goods and services through defined call-off arrangements. The framework award notice, published on October 23, 2026, identifies several appointed suppliers, including BAM Nuttall Limited, Barhale Ltd, and Costain Limited. The estimated contract duration begins on November 4, 2026, and runs through March 31, 2030, with potential extensions extending the agreement until 2035. All individual project contracts under this framework will be progressed in accordance with established project approvals and call-off procedures.
