Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the answer of 18 March 2026 to Question 120007, how much of the average annual real-terms reduction in HS2 capital spending between 2025-26 and 2029-30 will be achieved through (a) efficiency savings, (b) reprofiling of expenditure, (c) changes to project scope and (d) changes to the delivery timetable.

The HS2 Spending Review settlement reflects the scope of work that the HS2 programme plans to deliver over the period 2026/27 to 2029/30. The average annual real-terms growth rate of -7.9% detailed in the Spending Review report reflects changes in annual spend over this period, based on the expenditure profiles HS2 Ltd agreed with the Department for Transport to deliver Phase 1 scope. It reflects the stages of the programme and supports the reset of the programme Mark Wild is conducting.
