Question to the Department for Transport:

To ask His Majesty's Government what is the current estimate of the cost to complete the HS2 work between Old Oak Common and Handsacre, including the interchange station on the Great Western Mainline at Old Oak Common.

The Government announced in May 2026, the expected cost of delivering HS2 is now in the range of £87.7 - 102.7 billion. This is expressed in a mixed price base, including the cash outturn of works to date and the costs of future work excluding inflation.

These ranges cover the cost of the whole programme, stretching from London Euston to Birmingham Curzon Street and to the connection to the West Coast Main Line at Handsacre Junction, which will enable HS2 services to continue to the Northwest and Scotland. This includes the cost of HS2 work between Old Oak Common and Handsacre as well as the interchange station at Old Oak Common.
