seven.2) Information about modifications

seven.2.1) Description of the modifications

Nature and extent of the modifications (with indication of possible earlier changes to the contract):

Original award (30/05/2023-29/05/2027 + an optional 12-month extension to 29/05/2028). Contract value: £9,000,000

Modification one (29/07/2024): This modification was actioned to include two special terms into the contract. There were no amendments made to the duration or the value of the contract.

Modification two (29/10/2024): £4,500,000 (excl. VAT). Modified contract value: £13,500,000. DESNZ amended the contract to allow GBN and DESNZ to continue to access services to facilitate delivery of the SMR Technology Selection Process.

Modification three (06/06/2025): £2,600,000 (excl. VAT). Modified contract value: £16,100,000. DESNZ amended the contract to implement several changes, including an uplift in the value to enable continued utilisation of the contracted services until award of the GBN SMR TSP. The variation also seeks to clarify that GBN is not a party to the contract as of 01/04/2025 and amends the scope of the contract to include the latest work package between the Buyer and Supplier. Finally, the variation reverts to the original wording on indexation within the contract.

seven.2.2) Reasons for modification

Need for additional works, services or supplies by the original contractor/concessionaire.

Description of the economic or technical reasons and the inconvenience or duplication of cost preventing a change of contractor:

Additional services have become necessary to enabled continued access to the contract services and avoid a gap in service until the conclusion of the GBN Small Modular Reactor Technology Selection Process.

A change of contractor cannot be made for economic and technical reasons because the contractor's deep understanding of DESNZ's objectives, GBN, the SMR TSP and DESNZ workstreams cannot be delivered by another supplier in the required timescales.

Likewise, a replacement contractor would require several months to be fully onboarded onto the project, which would cause considerable inconvenience and delays to the SMR TSP, while duplicating costs amidst the dual running of two financial advisors.

seven.2.3) Increase in price

Updated total contract value before the modifications (taking into account possible earlier contract modifications, price adaptions and average inflation)

Value excluding VAT: £13,500,000

Total contract value after the modifications

Value excluding VAT: £16,100,000
