## Summary

The procurement process initiated by Trinity House, a central government public authority based in London, has culminated in the completion of a contract for a Bathymetric and Topographic Survey of Wolf Rock Lighthouse. This contract falls under the services category, specifically targeting bathymetric survey services. The method of procurement was limited competition below the threshold. Key dates include the signing of the contract on 25th June 2026, with the service period running from 1st August 2026 to 28th August 2026. The project is entirely carried out in the UK, with the awarded contract valued at £29,905 excluding VAT (£35,886 gross).

This tender presents significant business growth opportunities for companies specialising in survey and geospatial services, particularly small and medium-sized enterprises (SMEs) excelling in bathymetric and topographic surveys. The contract was awarded to Castle Surveys Limited, indicating an ongoing demand for niche expertise in surveying coastal and maritime structures. Similar businesses could position themselves strategically for future tenders by demonstrating a strong track record in marine-based survey projects and compliance with procurement requirements for public authority contracts.
