Costain awarded three-year extension to United Utilities maintenance contract
Costain Group PLC ("Costain") today announces that it has been awarded an extension to its existing Managed Service Provider (MSP) contract with United Utilities. Costain was first appointed by United Utilities as its MSP in 2019 and this three-year extension, during which Costain is expected to continue aiding the delivery of the AMP8 capital maintenance programme, takes the duration of this partnership to ten years and through the remainder of the AMP8 regulatory cycle.
Costain's team of more than 120 professionals provides best-in-class expertise in multi-disciplinary engineering and construction delivery, asset optimisation and project management and leverages its deep understanding of the water sector to deliver a wide range of replacement, refurbishment and asset upgrade services across the United Utilities estate in the north west of England. On the MSP framework to date, Costain has delivered more than 900 capital maintenance projects and approximately 9,000 responsive maintenance activities, enabling United Utilities to meet more than 160 key regulatory commitments ahead of schedule whilst maintaining excellent safety, health and environmental performance.
Costain is also a trusted partner to United Utilities as it invests £13.5bn in the region's water and wastewater infrastructure during the AMP8 regulatory cycle (AMP7 capital investment: £3.8bn), with an option to extend this relationship to the end of AMP9 in 2035.
Alex Vaughan, Chief Executive Officer of Costain, commented: "We are a long-term, trusted partner to United Utilities and this latest extension is testament to our track record of delivering predictably and consistently.
Across the north west of England, we are working closely with United Utilities and our local supply chain partners to build critical resilience into the region's water and wastewater infrastructure. We're continuing to achieve performance enhancing results by optimising existing assets and integrating engineering knowledge, innovation and best practice while maintaining the highest standards of safety and quality."
