## Summary

The Department for Energy Security and Net Zero (DESNZ), in collaboration with the DSIT Group Commercial, is overseeing a procurement process for financial advisory services. The tender title is "Financial Advisor for GBN / DESNZ," focusing on financial consultancy and management within the services category. The procurement process is currently at the Award stage, with an active contract modification undertaken on 6th June 2025 to extend services related to the GBN Small Modular Reactor Technology Selection Process. The associated contract, originally signed on 30th May 2023, is valid until 29th May 2027, with contract services available throughout the UK. Modification amendments have uplifted the contract value to £16,100,000 to ensure continuity of service without interruptions until the conclusion of key workstreams.

This tender presents significant business growth opportunities for financial consultancy firms with expertise in the energy sector. Given the technical and economic nature of the services required, larger consulting firms like Deloitte LLP have successfully positioned themselves to manage these complex demands. Businesses capable of providing expert financial advisory services, particularly those with robust infrastructure to support long-term government projects, are well-suited to compete. Continuity and depth of understanding of DESNZ's objectives and nuclear energy policies are essential for maintaining ongoing roles in facilitating the implementation of the Small Modular Reactor Technology Selection Process.
