## Summary

The Environment Agency has announced a procurement process for the long-term operation and maintenance of the Boston Tidal Barrier from 2026 to 2030. This project falls under the industry category of flood-defences maintenance works and is located in London. The procurement stage is currently at the planning phase, with the contract period set to commence on 15th September 2025 and potentially extend until 3rd December 2031. A pipeline notice was published on 21st May 2025, indicating upcoming procurement opportunities, with a future notice expected by 16th June 2025. The procurement method is through a tender initiated by the Department of Environment, Food and Rural Affairs, which facilitates the process via Defra group Commercial. The project is valued at £3,000,000, within the main procurement category of works.

This tender presents substantial opportunities for business growth, particularly for SMEs specialising in engineering, construction consultancy, and maintenance services. Companies with expertise in flood-defences and the repair and maintenance of electrical and mechanical building installations will find this procurement can align with their core competencies. Furthermore, the engagement with the public authority Environment Agency enriches business portfolios with high-profile infrastructure projects that contribute significantly to community safety.

## Notice

The Boston Barrier comprises a group of over 100 individual assets, including a radial gate flood barrier, which between them protect more than 14,000 residential properties and 800 commercial and community buildings. Since being active the barrier and associated assets have been operated and maintained under an NEC Term Service Contract. This contract comes to an end in December 2025. To ensure the continuing readiness of the gate and associated assets a new service contract for their long-term operation and maintenance is required.
