Notice Information

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.

Renewal: Due to the evolving nature of the programme and the length of contract, the volume and value of services required may vary over time. Additional units (subject to further approvals) represent a future option for GBE-N to instruct the Delivery Partner to support additional SMR deployments beyond the initial scope, delivered via contractually defined call-off mechanisms to ensure flexibility, transparency and compliance.
