## Summary

Thames Water Utilities Limited, an established private utility company based in Reading, has initiated a significant procurement process with the aim of awarding a framework agreement titled "Control and Automation" under tender ID FA2208. This project falls within the services category and targets multiple sectors, including electrical installation and software integration. Designed to support Thames Water's AMP8 delivery programme, it will address new installations, renovations, and remedial works across its operational estate. The procurement method employed is an open competitive flexible procedure, permitting clarification and negotiation over several stages before finalising the contract award. Key deadlines include the submission date for accessing and submitting the Pre-Specific Questionnaire (PSQ), set for 13 March 2026 at 10:00 AM GMT. The project encompasses various regions within the United Kingdom, focusing on improving infrastructure through lotting structures such as systems integration and fibre optic cabling.

This tender presents substantial opportunities for business growth for suppliers specialising in electrical installations, software consultancy services, and system support, among others. With a robust budget of £435 million available for the framework, Thames Water plans to award multiple suppliers across several lots, aiming for efficient and economical service solutions while maintaining secure and consistent delivery. Companies offering expertise in lot-specific areas such as motor control centres, sewage pumping station installations, and fibre optic cabling will find themselves strategically positioned to benefit from this framework. The competitive flexible procedure allows for direct award below a stipulated threshold and mini competitions, providing ample opportunities for businesses of varying sizes to engage and secure a partnership with Thames Water over a potential eight-year contract term, inclusive of renewal options.
