Question to the Department for Transport:

To ask the Secretary of State for Transport, what the Government's latest projected cost is for the London to Birmingham stretch of High Speed 2, with contingency identified separately.

The current estimated cost of Phase 1 of High Speed 2 (London to West Midlands) is £15.65 billion. A contingency provision of £5.75 billion has been set at P95 level. Based on these prices the cost per single track kilometre is £47.56 million for Phase 1, including £80, 000 per kilometre for noise barriers. These figures are in 2011 prices and at the P95 level, meaning that at this early stage there is a 95 percent confidence level that the project can be delivered for this cost.
