Question to the Department for Transport:

To ask the Secretary of State for Transport, what recent estimate he has made of the cost of the rescoped HS2 project; what recent estimate he has made of the benefit cost ratio of that project; and whether he plans to update the estimated costs of HS2 using 2024 prices.

In light of the Network North announcement, the scope of HS2 is now being reviewed to make sure only what is required for the reduced scheme is being delivered, including the revised approach to Euston. Once this work has been done, we will publish a cost range and benefit cost ratio for the revised HS2 scheme as part of an updated business case for the HS2 programme. The Department will publish this work when it is complete. HS2 records costs in 2019 prices and in nominal terms. Decisions over inflation methodologies and indices to express the wider programme's costs are ongoing between the Department and HM Treasury.
