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 value: £450,000 (excl. VAT). 21/06/2024-11/06/2027.

Modification one (30/10/2025): £225,000 (excl. VAT). Modified contract value: £675,000 (excl. VAT). Additional economic valuation advice is required towards the Small Modular Reactor Technology Selection Process. The modification also includes an amendment to the contract reference number. The contract duration remains unchanged.

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 are required due to extended project timeframes and additional requirements for economic valuation advice in the interim. Any change 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.

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: £450,000

Total contract value after the modifications
