## Summary

Nuclear Restoration Services Limited commissioned groundwater monitoring at Hinkley Point B, a nuclear power station in Somerset. The requirement is for ground investigation services focused on monitoring groundwater; the procurement description names the site and monitoring activity but does not break the work into specific tests, sampling tasks or reporting outputs. Delivery is at Hinkley Point B, postcode TA5 1UD, in the South West of England. This is a specialist environmental and ground investigation service tied to monitoring conditions at a nuclear site, rather than a general water-supply or construction contract. Suppliers whose work covers groundwater monitoring and ground investigation at complex industrial or nuclear locations are the closest fit.

The procurement is complete and has been awarded to WSP UK Ltd. The buyer used a selective call-off from a framework agreement. The award was made on 1 October 2026 for £134,258; the earlier estimated tender value was £100,000. The contract period runs from 5 October 2026 to 31 March 2028. The tender deadline was 28 September 2026 at noon. The procurement was classified as services, with a single stated monitoring requirement and no division into lots. Small and medium-sized enterprises and voluntary, community and social enterprises were marked as unsuitable. No evaluation criteria or scoring basis are stated in the process information.

For suppliers tracking future groundwater monitoring at Hinkley Point B, this award provides evidence of a defined buyer requirement and its delivery through a framework call-off. A credible competitor would need to demonstrate practical groundwater monitoring and ground investigation capability, with the equipment, technical staff and operational controls needed to work safely at a nuclear site. Experience managing access, site-specific safety requirements and reliable monitoring over a sustained contract would strengthen a supplier’s position, although the procurement does not set out specific accreditations or technical standards. The buyer marked SMEs and voluntary, community and social enterprises as unsuitable, indicating that the requirement was positioned for an established supplier with sufficient organisational capacity. WSP UK Ltd was selected for this requirement, giving the market a clear example of the supplier profile accepted for the work.
