UK Public Sector Contracts & Tenders

This tender seeks to establish a single-Lot Framework covering the provision of General Diving Services for United Utilities, for inland / inshore projects undertaking commercial diving operations in accordance with the Diving at Work Regulations 1997, the Approved Code of Practice for Commercial Diving Projects Inland/Inshore and any other applicable legislation.

United Utilities Water Limited intends to establish a multi-supplier framework agreement for the provision of Battery Energy Storage Systems (BESS) to support delivery of its Power Resilience Programme across operational water and wastewater sites. The framework will enable the deployment of distributed battery storage assets across approximately 225 operational locations, supporting enhanced power resilience, operational continuity and decarbonisation objectives during the AMP8 and AMP9 regulatory periods. The scope of the framework includes the supply of containerised or modular Battery Energy Storage Systems, including battery modules, power conversion systems (PCS), energy management systems (EMS), monitoring and control systems, and associated balance-of-plant components required for integration with existing electrical infrastructure. Systems will support resilience requirements such as backup power during grid outages, peak demand management and, where appropriate, participation in grid flexibility services. Suppliers appointed to the framework will be expected to provide equipment warranties, performance guarantees and options for long-term service and maintenance to support reliable lifecycle operation. The scope may also include technical support for design integration, commissioning assistance, remote monitoring capabilities and integration with site-level control systems, including SCADA where required. The framework will appoint a limited number of experienced suppliers capable of delivering scalable and standardised BESS solutions suitable for deployment across a diverse portfolio of operational sites with varying power and capacity requirements. Call-off contracts for individual deployments may be awarded through direct award or mini-competition in accordance with the framework terms.

As part of its commitment to reducing water demand and leakage, United Utilities is seeking to engage with the market to better understand the availability and capability of suppliers able to provide specialist onsite support associated with enforcing access to customer premises for the repair of customer‑side leaks. Under Section 75 of the Water Industry Act 1991, United Utilities has a statutory duty to ensure that leakage is repaired as quickly as possible. While established processes exist to notify customers and to support eligible vulnerable customers with leak repairs, there are occasions where access is denied and unresolved leakage presents a continued risk to the environment, third‑party property, and the water network. In such circumstances, United Utilities may obtain a court‑issued warrant to gain access. United Utilities own operational teams will undertake the physical leak repair works; however, additional support is required to coordinate and manage the safe, lawful, and proportionate execution of the warrant onsite.
