## Summary

The Environment Agency procured construction works for the Castle Mills eel pass, intended to support river regulation and flood-control activity. The requirement concerns a specific eel-pass project rather than general environmental consultancy or routine maintenance. Delivery is associated with Castle Mills in Leeds, Yorkshire and the Humber. The procurement falls within the works category and is relevant to contractors able to undertake civil engineering or water-environment construction projects. The buying organisation is the Environment Agency, whose Leeds address is also associated with the requirement. The named project title identifies the work as the YNE-AOMR-MC-Castle Mills Eel pass, with the procurement described as a mini competition for Castle Mills eel pass.

The procurement has been awarded and the tender is complete. It used a selective procedure as a call-off from a framework agreement. Bids were due by 24 July 2026 at 12:00. The contract was awarded to Esh Construction Ltd on 24 August 2026 for £469,441. The contract period runs from 27 July 2026 to 31 March 2027. The published procurement value and awarded value are both £469,441. The requirement was treated as a single project, with the award recorded as active. The procurement was not reserved for small and medium-sized enterprises or voluntary, community and social enterprises. The award information identifies Esh Construction Ltd as the selected supplier.

This award demonstrates established demand from the Environment Agency for specialist construction supporting river regulation, flood control and eel passage at a named infrastructure site. The successful supplier was a large construction company, indicating that comparable future requirements may suit businesses with substantial delivery capacity, civil engineering capability and experience working on water-related infrastructure. Suppliers seeking to compete for similar Environment Agency work would need to understand framework call-off competitions and show they can manage construction delivery in an environmentally sensitive river setting. Relevant experience in fish passage, river engineering, flood-control works, site management and safe delivery around operational watercourses would strengthen credibility when this type of requirement next reaches the market.
