## Summary

Defra Commercial commissioned services titled “T506: Groundwater Chemistry”. The requirement concerns groundwater chemistry and is classified under CPV 80532000, described in the procurement data as management training services. It is a services contract for work associated with Defra Commercial, based at 17 Smith Square, London. Delivery locations include the United Kingdom, Europe, the Isle of Man, the Channel Islands, British Overseas Territories and the rest of the world. The named requirement points to environmental and groundwater-related consultancy, although the classification also indicates a training-services element. Businesses operating in environmental consultancy, groundwater assessment, water quality or related technical training would find the subject matter most relevant.

The procurement is complete and has been awarded following a direct single-tender action below the threshold. The tender deadline was 1 September 2026 at 12:00. Defra Commercial awarded the contract to Stephen Buss Environmental Consulting Ltd on 2 September 2026 for £35,547.04 including the stated GBP currency. The contract runs from 1 October 2026 to 30 September 2031. The published data records one active award and one supplier. The opportunity was identified as suitable for small and medium-sized enterprises and voluntary, community and social enterprises. The process used a direct procurement route rather than an open competition.

For suppliers that did not win, this award demonstrates that Defra Commercial buys specialist groundwater chemistry services through a below-threshold single-tender route and can commit to a multi-year requirement. A credible future supplier would need practical expertise in groundwater chemistry, environmental investigation and interpretation of water-quality data, together with the ability to provide clear technical advice to a public-sector buyer. Because delivery may cover the United Kingdom and wider territories, relevant geographic reach and the capacity to support work across varied locations would strengthen a competing offer. Environmental consultancies and specialist independent firms may be well placed, particularly where they can combine scientific capability with effective reporting, stakeholder communication and technical training.
