## Summary

Great British Energy - Nuclear commissioned specialist commercial, project and advisory support for its upcoming major procurements in the Gwyndod Small Modular Reactor programme. Delivery Support Services 2 provides access to professional expertise across project delivery, commercial activities, governance and stakeholder engagement, as well as other business-critical services needed to meet the organisation’s programme objectives. The work is consultancy and related business-management support, rather than construction or reactor supply. Services are drawn down as required over the contract term. The buyer is Great British Energy - Nuclear, based in Warrington. The procurement identifies the delivery location only as the United Kingdom, without a more specific worksite.

The procurement is complete and the contract was awarded to Deloitte LLP. The award was made on 7 October 2026, with a contract value of £6 million; the contract is active. The arrangement is a call-off from the Government Commercial Agency’s Management Consultancy Framework 4, under Regulation 33 of the Public Contracts Regulations 2015. It used a limited procedure without prior publication of a competition notice. The procurement was divided into one lot, which is marked cancelled in the lot data despite the active award and contract. Price was the stated award criterion. Three bids were recorded for the lot. The contract was signed on 7 October 2026. Subcontracting is permitted, but the proportion is unknown because work is drawn down as required.

This award shows demand from Great British Energy - Nuclear for consultancy that can support major nuclear programme procurements, combining commercial expertise with project delivery, governance and stakeholder engagement. A credible competitor for a future requirement of this kind would need to provide flexible access to a broad team of specialist advisers, able to respond to changing needs across several disciplines rather than deliver a single fixed service. Experience supporting complex public-sector procurement and major infrastructure or energy programmes would be relevant to demonstrating that capability. The route used here was a call-off from an established management consultancy framework, so suppliers seeking comparable work would need access to an appropriate framework or a route to participate through its suppliers. The contract also demonstrates that pricing formed the stated basis of selection.
