## Summary

The Environment Agency procured construction support for the Castle Mills eel pass. The requirement concerns river regulation and flood control works, with the service focused on supporting construction of an eel pass rather than supplying general construction materials. It falls within the services category and is to be delivered in Leeds, at the Environment Agency’s Lateral office on City Walk and the associated Castle Mills location identified by the delivery postcode. The buyer is the Environment Agency, based in Leeds. This requirement is relevant to engineering, environmental and infrastructure businesses that provide specialist support for fish passage schemes, river works or related flood and water-management projects.

The procurement has been completed and awarded following a selective call-off from a framework agreement. The tender closed on 3 August 2026 at 12:00. The contract was awarded to Ove Arup & Partners Limited on 12 August 2026 for £29,517 including the stated currency of GBP. The contract period runs from 5 August 2026 to 30 October 2026. The award is active, and the tender status is complete. There is a single requirement and a single award. The procurement was evaluated through the framework call-off route. The opportunity was recorded as unsuitable for small and medium-sized enterprises and for voluntary, community or social enterprises.

For a supplier that did not win this award, the procurement indicates demand from the Environment Agency for specialist construction support connected with eel-pass and river-management infrastructure. Businesses best placed for comparable work would have practical experience supporting delivery of fish-passage schemes, river regulation or flood-control works, and the ability to work alongside construction teams and public-sector project managers. Relevant capability may include environmental engineering, water-management design support, site coordination, technical advice and managing delivery risks around watercourses. The selected supplier was Ove Arup & Partners Limited, indicating that substantial professional engineering and infrastructure consultancy capability was valued. A future competitor would also need access to the relevant framework route and capacity to support a short, focused assignment.
