## Summary

The procurement process for the "CS2455 South West Disagreement Resolution and Mediation Services" was led by Wiltshire Council, aimed at acquiring services in the special education and legal advisory sectors in the UK region UKK15. Originally, the tender followed an open procedure allowing for broad competition and participation, with submissions via the Proactis portal. The initial tender phase concluded in June 2026, and an award was made by mid-July 2026 to Collis Mediation Limited, yet ultimately the contract process was terminated by Wiltshire Council on 21st July 2026 for public interest reasons, thereby ceasing the procurement at that stage.

This opportunity presented significant growth potential for businesses specialising in mediation and dispute resolution services, particularly for SMEs due to the openness of the procedure. The contract was estimated at a gross value of £9,000,000, emphasising the project's scope and the substantial financial engagement for the successful bidder. Businesses with expertise in special education services, community and social services, and legal advisory capacity would have found this tender particularly aligned with their service capabilities, promoting a dynamic regional engagement across several participating Joint South-West Region Authorities.
