## Summary

The procurement process initiated by Trinity House on behalf of the central government involved a contract for hydrographic surveys across nine sites. This project, classified under hydrographic surveying services, saw a completion with a contract signed on 18 August 2025 and active until 31 July 2026. The buying organisation, based in London, facilitated this procurement under a limited competition method, specifically structured below the threshold for such processes. The tender's legal basis rests on the legislation of 2023/54, with location-specific delineation being highly dependent on prevailing weather conditions, informing the contract's completion schedule. Trinity House has appointed G J Binding and Sons, a South Glamorgan-based SME, as the supplier tasked with fulfilling the contract valued at £47,706.25 exclusive of VAT.

This tender represents significant opportunities for businesses adept in hydrographic surveying services, particularly SMEs looking to expand their portfolio through government contracts. G J Binding and Sons, possessing commendable expertise and operational capacity, illustrates the bid potential for specialised suppliers capable of delivering precise delineation surveys in challenging environments. Involvement in this procurement allows companies to strengthen their market position and credibility, especially those situated within the UK, aligning with government partnerships. Businesses situated within similar niche service provisions are encouraged to consider tendering for analogous contracts, thereby building strategic relationships within the public sector and leveraging location advantages.
