To ask His Majesty's Government, with regard to their policy paper Spending Review 2025: Departmental Efficiency Plans, published on 11 June, which states that a zero-based review will help the Treasury "get smaller", whether they will publish the outputs of this review; and what proportion of administrative functions are expected to be outsourced, automated, or removed entirely by 2028–29.

As part of the Spending Review 2025, HM Treasury, alongside all government departments, undertook a zero-based review (ZBR) of its expenditure. This review was performed as per the requirements of the Spending Review. The outputs are intended for internal decision-making processes, not for publication. The Spending Review settlement for HMT means the department will need to get smaller, delivering a 10% reduction in its admin budgets by 2028-29. The detailed business planning process to achieve those reductions, including a review of administrative functions, over the Spending Review period is currently in progress. The outputs from the ZBR are being used to support this.
