To ensure transparency around the project, we have provided our latest schedule and cost estimates for HS2 to the National Audit Office who reported on the programme last week. These estimates depend, among other things, on the scope of what, if anything, the Government decides to build and which risks come to pass. In August 2019 the Government commissioned the independent Oakervee Review to provide advice on whether and how to proceed with HS2. The Government will make a decision shortly.
