Question to the HM Treasury:

To ask the Chancellor of the Exchequer, pursuant to the answer of 23 December 2025, to Question 98157, on Customs: Digital Technology, what is the status of the Single Trade Window programme, how many HMRC staff now work on it, and whether it has been funded in the Spending Review 2025.

The delivery of the Single trade Window (STW) has been paused and additional funding was not provided in the Spending Review 2025. Therefore, there are currently no HMRC staff assigned to the operational delivery of the STW programme. However, policy development continues with resources from a range of teams including Customs Policy and Strategy and Customer Services and Operations.

The government’s policy development work is focussed on understanding industry needs and designing a service that delivers genuine value to businesses and strengthens the UK’s border system.

The STW programme had £180 million funding allocated at the 2021 Spending Review across three financial years - 2022/23 to 2024/25. The final spend on STW over 22/23, 23/24 and 24/25 was £111.44 million.
