## Summary

Defra Commercial procured professional services for T503: Hydrogeological Conceptual Modelling. The requirement concerns developing hydrogeological conceptual models, which represent how groundwater systems work and support assessment and management of groundwater conditions. It is a services contract and is identified under CPV 80532000, although that code describes management training services rather than hydrogeological modelling. The buyer is Defra Commercial, based at 17 Smith Square, London. Delivery information covers the United Kingdom, including the London address, as well as Europe, the Channel Islands, the Isle of Man, British Overseas Territories and the rest of the world. This is relevant to environmental consultancies, hydrogeologists and groundwater specialists able to provide modelling services across the stated geographical scope.

The procurement has been awarded and the tender is complete. Defra Commercial used a direct single-tender action below the threshold. The tender deadline was 1 September 2026 at 12:00. The contract was awarded on 2 September 2026 to Groundwater Science Ltd for £37,747.90 including the stated GBP currency. The awarded contract period runs from 1 October 2026 to 30 September 2031. The procurement was classified as a services requirement and was identified as suitable for small and medium-sized enterprises and voluntary, community and social enterprises. The award is active. The published process information identifies one awarded supplier and one requirement for hydrogeological conceptual modelling.

This award is evidence that Defra Commercial buys specialist groundwater and hydrogeological modelling capability through a direct, below-threshold route. A competitor seeking similar work would need credible expertise in hydrogeology and in producing conceptual models that can support groundwater assessment and management. The requirement is suitable for SMEs and voluntary, community and social enterprises, so the market is not limited to large corporate suppliers. Groundwater Science Ltd’s selection shows that a specialist technical consultancy can satisfy this type of public-sector requirement. Relevant suppliers should be able to demonstrate practical modelling capability, understand groundwater systems and communicate technically robust outputs for Defra’s needs. The broad delivery geography also favours organisations able to work across the United Kingdom and other stated locations.
