Question to the Department for Transport:

To ask Her Majesty's Government what is their latest estimate of the costs and construction time of the current consented scheme at Wendover on HS2 Phase One.

The cost of delivering the new railway is spread across a number of contracts that cover different geographical areas. For Wendover this includes Enabling Works (Fusion JV for Colne Valley to Long Itchington), Main Civil Works (EKFB for Chilterns Tunnel North Portal to Long Itchington Tunnel South Portal) and railway systems contracts (separate route-wide contracts including signalling, rails, track bed, and overhead line equipment).

HS2 Ltd does not routinely apply cost apportionment on the basis of geographical sections, as cost and schedule control measures are applied to the contractors delivering specific requirements or assets which will typically sit across geographical boundaries.

However, the delivery of the new railway in the Wendover area, and across the Phase One route, remains within both the budget and schedule estimates provided at the point of Notice to Proceed in April 2020.
