## Summary

Defra Commercial commissioned specialist management training on groundwater flow and contaminant transport modelling, focused on fundamentals. The requirement is a services contract for training delivery rather than construction, environmental remediation or modelling consultancy. The subject matter combines groundwater science, contaminant transport and the practical management of modelling work. Delivery is associated with London and can cover the United Kingdom, Europe, the Isle of Man, the Channel Islands, British Overseas Territories and other locations worldwide. The buying organisation is Defra Commercial, based at Smith Square in London. This opportunity is most relevant to training providers, specialist environmental consultancies and individual experts with demonstrable ability to teach groundwater modelling concepts to a professional audience across potentially wide geographic locations.

The procurement is complete and has been awarded following a direct single-tender action below the threshold. The submission deadline was 1 September 2026 at 12:00. Defra Commercial awarded an active contract to Steven Thornton on 2 September 2026 for £62,333.27, with a contract period from 1 October 2026 to 30 September 2031. The procurement was evaluated as a services requirement for management training. The award covers one requirement: Groundwater Flow and Contaminant Transport Modelling: Fundamentals. The tender was identified as suitable for small and medium-sized enterprises and voluntary, community and social enterprises. The selected supplier is named as an individual rather than a corporate organisation.

For suppliers that did not win this procurement, the award demonstrates a defined need within Defra for specialist training linking groundwater flow, contaminant transport and modelling fundamentals. A credible future competitor would need strong subject knowledge in groundwater and contaminant transport modelling, together with the ability to explain technical principles clearly through structured professional training. Providers should be able to manage delivery for a public-sector client and support learners across the United Kingdom and potentially international locations. The stated suitability for SMEs and voluntary, community and social enterprises indicates that smaller specialist providers and independent experts may be well placed, provided they can evidence relevant teaching capability, technical experience and reliable delivery arrangements.
