Rating: Compared to financial year 24/25 Q4, the NISTA/SRO Delivery Confidence Assessment (DCA) rating at 25/26 Q4 remained at Amber. This is primarily due to the following factors. 1. The Delivery Confidence Assessment reflects successful completion of nine projects by the programme team up to 2025/26. 2. Despite recent successes, our resource position remains a risk. We continue to face challenges in recruiting sufficient staff and securing the level of industry support required to sustain delivery. Resourcing needs will have to be proactively managed to ensure we can maintain momentum and meet our commitments.

Schedule: Compared to financial year 24/25-Q4, the programme end-date at 25/26-Q4 remained the same at 01/04/2032.

Cost: Compared to financial year 24/25-Q4, the project's departmentally-agreed Whole Life Cost at 25/26-Q4 (measured in £m) increased from £1876.3M to £3287.2M. This is primarily due to the following factors. 1. The forecast Whole Life Costs has increased to reflect new requirements and improved understanding of the conditions of the existing infrastructures and the levels of intervention required to achieve the required programme outcomes.

Rating: The Project's Delivery Confidence Assessment rating at 24/25-Q4 is AMBER, compared with the Infrastructure and Projects Authority's assessment last year of AMBER. This is due to the following factors. The DCA reflects ongoing work by the programme team to deliver a number of key projects during 2024/25.

Schedule: Compared to financial year 23/24-Q4, the project's end-date at 24/25-Q4 remained at 01/04/2032.

Cost: Compared to financial year 23/24-Q4, the project's departmentally agreed Whole Life Cost at 24/25-Q4 (measured in £m) increased from 1870 to 1876. This is primarily due to the following factors. The programme remains within approval tolerances.

Rating: The Infrastructure Project Authority's Delivery Confidence Assessment rating at 23/24-Q4 is Amber. This is primarily due to the following factors. Sustaining delivery to plan will take significant effort (people and funds) over the next 4 years as CIP delivers the most complex phase of the programme in close proximity to submarine operations. The two main issues affecting delivery confidence are, delivery planning for recapitalisation of existing facilities while they continue to be used for submarine operations, and attracting and retaining skilled staff, particularly with nuclear skills but also with programme/project skills, to a remote site in a very tight labour market in western Scotland.

Schedule: Compared to financial year 22/23-Q4, the programme's end-date at 23/24-Q4 remained scheduled to finish on 2032-04-01

Cost: Compared to financial year 22/23-Q4, the project's departmental-agree Whole Life Cost at 23/24-Q4 increased from 1869m. to 1870m. This is primarily due to the following factors. The programme has been subject to Reference Class Forecasting (RCF) analysis, focused on the Faslane and Coulport portfolios and the challenges in delivering in a nuclear and operational environment. From this RCF analysis a revised forecast has been introduced which has increased the WLC of the programme. This considers the impacts of operational constraints, resource availability, extraordinary inflation and material availability.
