The Department is transparent on cost pressures and publishes six-monthly parliamentary reports on HS2, providing progress updates on the programme. It will take some time to fully understand the impact of the 9 March announcement on HS2 and we are using this time to invest in more mature designs and delivery approaches with a view to ensuring the programme is delivered in the most cost-effective way and protecting the Government’s commitment to delivering HS2 from Euston to Manchester.
