## Summary

On 29th July 2025, the Defence Equipment and Support, a sub-central government authority based in Bristol, initiated a direct award contract with Geoacoustics Ltd for services related to the Pulsar S2094 Sidescan Sonar. The contract is valued at £880,000 and spans a period from 1st September 2025 to 1st September 2030, with an additional option to extend by up to two years. This procurement falls under the service category, specifically surveying and hydrographic instruments, and is justified under the Procurement Act 2023 due to Geoacoustics Ltd being the sole source capable of providing the required support and maintenance for their proprietary sonar systems.

This procurement represents a significant opportunity for Geoacoustics Ltd, as it underscores their unique position in the hydrographic instrument industry. The direct award provides business continuity and growth through the maintenance and support services they offer, reinforcing their expertise and exclusive capability in handling high-tech marine survey equipment. Small and medium enterprises (SMEs) with specialised skills in advanced technological maintenance and a focus on niche markets like hydrographic services may find similar opportunities in single-source contracts with public authorities, particularly where a high level of technical expertise and proprietary control over service tools and techniques is advantageous.
