## Summary

Nuclear Restoration Services Ltd commissioned remediation of sumps at the LETP facility in Harwell. The requirement is a specialist environmental and ground investigation service, classified under CPV 71351500, focused on remediation rather than general site investigation. Delivery is at Harwell, Oxfordshire (OX11 0GD). The procurement description identifies the facility and remediation task but does not set out the specific sump condition, treatment method, materials or work packages. Suppliers whose work covers investigation and remediation of contaminated or otherwise problematic site infrastructure may find the subject relevant; firms focused only on unrelated construction or routine services are less closely aligned.

The procurement is complete and has been awarded to WSP UK Ltd. Nuclear Restoration Services Ltd used a selective call-off from a framework agreement. The estimated procurement value was £200,000; the awarded value is £220,803.77. The award was made on 24 September 2026, with the contract period running from 28 September 2026 to 27 August 2027. Submissions had to be received by 3 August 2026 at 18:00 UK time. The requirement was treated as a single service contract, with no lots identified. The tender was marked unsuitable for SMEs and voluntary, community and social enterprises. The published description does not give a separate evaluation formula or detailed eligibility thresholds.

The award shows Nuclear Restoration Services buying specialist sump remediation at its Harwell site through a framework call-off, with WSP UK Ltd selected for the work. A credible competitor for a future requirement of this kind would need to demonstrate relevant experience investigating and remediating site sumps, and the technical ability to plan and deliver work in a nuclear restoration setting. The single-site, specialist service points to the importance of fitting the buyer’s framework route and having the capacity to complete a defined remediation contract. The procurement is marked unsuitable for SMEs and voluntary, community and social enterprises, indicating a requirement aimed at larger or otherwise appropriately resourced suppliers. The scope published here does not identify specific accreditations or technical methods.
