The question

To ask the Secretary of State for Transport, pursuant to the Answer of 5 June 2026 to Question 3549 on High Speed 2 Line, when she expects the updating of the HS2 programme business case and the resetting of the benefits baseline to be completed; and whether she plans to publish the revised benefits baseline.

Answered by Simon Lightwood

DfT and HS2 Ltd are currently in the process of updating the programme business case and resetting the benefits baseline in line with the ongoing programme reset, which should be complete by Spring 2027. The programme benefits and how HS2 will realise them will be outlined in detail in the updated Business Case, which will be published. This is in line with our previous approach to publishing information on HS2 benefits.
