## Summary

The West Yorkshire Combined Authority has concluded the procurement process for the "Natural Flood Management Interim Evaluation," involving evaluation consultancy services. This contract, awarded to Wavehill Ltd, emphasised a selective procurement method using a restricted procedure. The award stage was completed on 6th November 2025, marking the transition from tender to contract execution, which commenced on 14th October 2025 and will continue through to 31st March 2026. Although the contract is based in Leeds, the deliveries and services extend beyond, covering regions such as the Channel Islands, Isle of Man, and globally, underlining the expansive nature of the evaluation work undertaken. The evaluation industry category aligns with the CPV code 79419000, indicating specialised consultancy tasks.

This tender offers significant business opportunities, particularly for large-scale consultancy providers skilled in evaluation services. The interim programme will enable firms to demonstrate and quantify their expert ability in assessing the impacts of flood management schemes across diverse geographical locations. Companies involved in consultancy services, with the capacity to cater to international requirements or a broad service delivery, will find this specific contract a fitting opportunity to showcase their expertise in delivering comprehensive evaluations. Additionally, as the tender does not cater to SMEs or VCSEs, businesses looking to expand their market reach within the consultancy sector will greatly benefit from engaging with such expansive projects facilitated by established authorities like the West Yorkshire Combined Authority.
