March 2024

Rating: Compared to financial year 22/23-Q4, the Infrastructure Project Authority's Delivery Confidence Assessment rating at 23/24-Q4 remained at Amber. This is primarily due to the following factors. The Single Trade Window (STW) programme has onboarded a technical delivery partner to co-design, build and operate the UK STW digital service. The first elements of a live STW offering has been built and we are now testing the first release of STW functionality with a number of invited users, using their feedback to inform improvements of the STW future design, whilst enabling the traders using the beta service, to meet their border obligations. The user testing period has been extended to gather additional insight and to further optimise the functionality, resulting in a slightly later public release in late summer 2024. Safety and Security (S&S) is on track and will be delivered by October 2024 in line with the Border Target Operating Model commitment, allowing users to comply with S&S regulations via STW.

Schedule: Compared to financial year 22/23-Q4, the project's end-date at 23/24-Q4 remained schedule to finish on 2027-03-31. This is primarily due to the following factors. The STW programme is on track to complete by the end date of 31 March 2027

Cost: Compared to financial year 22/23-Q4, the project's departmental-agree Whole Life Cost at 23/24-Q4 increased from 198m. to 342m. This is primarily due to the following factors. The increase in cost is due to the previous costs (2022/23) only including the first three years and the revised costs reflecting the programme whole life cost.
