Southern Water awards new Capital Delivery Frameworks to eight companies, as work steps up ahead of 2025-30 spending period

In preparation for the upcoming 2025-30 industry spending period, Southern Water has today awarded contracts to eight companies across two new Capital Delivery Frameworks to boost our performance for customers and the environment. 

These partners will now carry out work under either the ‘Strategic Delivery Partner’ or ‘Infrastructure Low Complexity Delivery Route’ frameworks.  

Those in the former group will be responsible for major infrastructure projects like constructing new pipelines and pumping stations, or non-infrastructure schemes like upgrades to our water supply works or wastewater treatment works.  

Meanwhile, partners in the latter group will either focus on water or waste, and this will typically involve design and build projects on our water supply network or sewers. 

Costain and MWH Treatment (as part of the CMDP+ joint venture), Kier Integrated Services Ltd, and Galliford Try Construction Ltd have all been awarded places on the Strategic Delivery Partner framework for non infrastructure above ground works. Meanwhile, Morrison Water Services Ltd have been awarded a place on the Strategic Delivery Partner framework for infrastructure works. 

Separately, the Infrastructure Low Complexity Delivery Route framework has awarded places to Clancy Docwra Limited, United Living Infrastructure Services, and Barhale Limited for works on the water side, and Clancy Docwra Limited, J Browne Construction Co Ltd and Morrison Utility Services Ltd on the wastewater side. 

This announcement follows Southern Water’s previous award of two other Capital Delivery frameworks – the ‘Professional Services’ framework and the ‘Non Infrastructure Low Complexity Delivery Route’ – marking the completion of procurement of the company’s entire Capital Delivery supply chain for AMP8.  

The total value of the frameworks is approximately £3.7bn over the initial contract term, which is seven years for the ‘Strategic Delivery Partner’ framework and five years for the ‘Low Complexity Delivery Route’ framework. Both have options to extend. 

Southern Water’s Chief Financial Officer, Stuart Ledger, said: “This announcement marks an important milestone in our preparation for the next regulatory investment period 2025-30 and beyond. Southern plans to more than double its investment over the next 5 years to meet the needs of customers and the environment. I am confident that working together with our partners we will fully meet this challenge.”
