  • 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: £5,000,000 (excl. VAT). 11/05/2022-10/05/2024 (+ an optional 12-month extension) Modification one: £2,500,000 (excl. VAT) + 12-month extension. 11/05/2022-10/05/2025.

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 £900,000. This notice will correct that to £9,000,000.00.**Value not stated

Rationale
Need for additional works, services or supplies by the original contractor/concessionaire: Additional services are required towards the completion of the SZC capital raise process due to extended project timeframes. Any change in contractor would cause significant inconvenience and substantial duplication of costs because the incumbent is uniquely placed to advise HMG and the project is at a critical stage close to completion.
