Question to the Department for Transport:

To ask the Secretary of State for Transport, with reference to paragraph 2.18 of the National Audit Office report entitled High Speed Two: A progress update, published on 24 January 2020, whether HS2 Limited has updated its indicative estimate that the cost of undertakings and assurances was £1.2 billion; and in which year's prices was that estimate.

HS2 Ltd has not updated this figure. The estimate was provided to the National Audit Office in late 2019 – at that time, HS2 Ltd’s cost estimates were in 2015 prices.
