Summary of the contracting process

The procurement process initiated by Great British Energy - Nuclear is for the role of a Delivery Partner to support the development and delivery of a significant programme. The role involves providing technical, commercial, and project management expertise. The procurement, under the Competitive Flexible Procedure as per the Procurement Act 2023, was updated on 29th June 2026 and is currently in the tender stage of progress. The contract's estimated value is £1,080,000,000, inclusive of VAT, with an anticipated contract period from September 2027 to September 2041. This opportunity is situated in London, United Kingdom, with services primarily related to civil engineering consultancy and infrastructure support, among others. The call for tenders will close on 6th August 2026, while the final award period is set to end on 16th September 2026.

This tender represents a significant opportunity for businesses specialising in infrastructure consultancy, project management, civil engineering, and environmental assessments. It is particularly suitable for firms with strong technical capabilities and experience in handling complex projects, potentially structured as joint ventures or consortia to meet the outlined requirements. Participating firms will benefit from a 14-year contract term, which offers stability and potential business growth. The competitive nature of the procurement process, which includes multiple stages of evaluation, allows firms to showcase their expertise and secure a substantial share of future infrastructure projects. Furthermore, the opportunity for future renewals and additional services enhances the potential for long-term collaboration and development within the energy sector.

Notice Title

UK4 - Tender Notice - Delivery Partner

Notice Description

The Delivery Partner (DP) will be responsible for supporting the development and delivery of the programme, providing technical, commercial and project management capability to ensure effective planning, risk management and delivery of defined outcomes. The estimated value is PS1,080,000,000 inclusive of VAT based on the contracting authority's current assumptions regarding programme scope, delivery profile, and resource requirements over the contract term. Due to the evolving nature of the programme and the length of contract, envisaged at 14 years, the volume and value of services required may vary over time. The stated value therefore represents an estimated total potential spend rather than a committed or guaranteed amount. In addition, progression through design stages and associated milestones or gates will determine the timing and extent of services required, potentially influencing the overall contract value over time. This estimate has been prepared in accordance with the valuation principles set out in the Procurement Act 2023.

The PSQ will cover topics including, but not limited to, technical and professional ability, economic and financial standing, and organisational capability to deliver a complex infrastructure programme. Applicants will be required to demonstrate that they meet these conditions on a pass/fail basis, including evidence of relevant experience, effective supply chain management, and appropriate systems, standards and governance. Only applicants that satisfy all applicable conditions of participation will be invited to progress to the next stage of the procurement process. Following evaluation of Initial Tenders, GBE-N intends to down-select a shortlist of the highest-scoring Tenderers. These shortlisted Tenderers will be invited to participate in an Enhanced Information, Dialogue and Due Diligence stage, during which GBE-N will engage with each Tenderer to clarify and refine their proposals, test deliverability, and further develop commercial and technical solutions Following completion of Dialogue, Tenderers will be invited to submit an Invitation to Submit Final Tender (ISFT). Final Tenders will be evaluated to identify the Most Advantageous Tender, after which a Preferred Bidder will be selected, approvals obtained, and the procurement will proceed to contract award following a standstill period."
