## Summary

The procurement process detailed here involves the Department for Energy Security and Net Zero, which is seeking financial advisory services for the Sizewell C project. The contracting authority, situated in London, is working with Barclays Bank Plc to provide these services under the category of financial consultancy. This process is currently in the contract modification stage due to extended project timelines, with a procurement goal to support the capital raise process of Sizewell C. The contract, originally valued at £5,000,000 excluding VAT, has undergone modifications to a total of £9,000,000 and an extension to 10th December 2025. This is a result of necessary additional services that were identified owing to the project's extended timeline.

This tender presents significant opportunities for businesses involved in financial consultancy services, specifically those experienced in substantial capital projects and advising governmental bodies. The extension and expanded scope suggest that established financial service providers with a robust track record in managing and strategizing large-scale investment initiatives are well positioned to benefit. These businesses can leverage their advisory expertise in financial structuring and policy-oriented investment decisions, thereby enhancing their portfolio whilst potentially providing significant value to the government’s objectives around the Sizewell C programme.

### Lot Information

Lot 1

This is a modification to an existing contract between the Department for Energy Security and Net Zero and Barclays Bank Plc. The scope of the contract is for the provision of financial advisory services to assess, input, and challenge the design, management and execution of the SZC capital structure and capital raise process; and to provide advice in relation to key judgements and decisions that will be required from HMG in order for it to execute its policy objectives and make sound investment decisions that represent Value for Money for the taxpayer. Additional services have become necessary due to extended project timelines. The supplier's services are essential to the completion of the capital raise process and progression of the Sizewell C programme. The variation is composed of a 7-month extension in time and a 30% extension in value under Regulation 72 (1) (b) and 72 (2) of the Public Contracts Regulations 2015. Original award value: PS5,000,000 (excl. VAT). 11/05/2022-10/05/2024 (+ an optional 12-month extension) Modification one: PS2,500,000 (excl. VAT) + 12-month extension. 11/05/2022-10/05/2025. Modified contract value: PS7,500,000. Modification two: PS1,500,000 (excl. VAT) + 7-month extension. 11/05/2022-10/12/2025. Modified contract value: PS9,000,000. **Please note that this notice was originally published on 30/05/2025 (Notice identifier: 2025/S 000-028653). However, there was an error in the field titled 'Total contract value after the modifications', which mistakenly suggested that the total contract value post-modification was PS900,000. This notice will correct that to PS9,000,000.00.**
