Thames Water has awarded a number of  AMP8/9 contracts for its AMP8/9 Major Projects Framework with an estimated total value of £4.8 billion including VAT.

The framework is intended to support the development and delivery of major water and wastewater capital projects across Thames Water's operational area during AMP8, with provision for use during AMP9 subject to the framework terms and applicable approvals.

The framework will provide a route for the award of project-specific contracts covering pre-construction services, engineering, construction and associated works, goods and services. Individual project contracts will be progressed in accordance with the framework's call-off arrangements and relevant project approvals.

The following companies have all been awarded a contract under the framework:

• Amentum Enterprise Asset Solutions Ltd.
• Bam Nuttall Ltd.
• Barhale Ltd
• Binnies UK Ltd.

• Costain Ltd.
• Ferrovial Construction (UK) Ltd.
• Galliford Try Construction Ltd.
• A. J. Murphy & Sons Ltd.
• Kier Infrastructure And Overseas Ltd.
• Mott Macdonald Bentley Ltd
• Taylor Woodrow Infrastructure Ltd.

The Framework will cover major works and asset upgrades across Thames Water's operational regions, with a focus on fostering long-term partnerships and reducing unnecessary bidding efforts. Contracts awarded under the Framework will include works, goods, and services essential to AMP8 delivery, with potential to extend into AMP9 based on performance.

Earliest date the contract will be signed is 4 November 2026 – the standstill period will end on 3 November 2026

Current estimated start and end contract dates are 4 November 2026 to 31 March 2030 with further possible extension options up to 31 March 2035.
