Revised plans for HS2 Euston terminus would cost almost £5bn, says watchdog

NAO warns cost of station in London almost double initial budget and pause on work could push it higher

The cost of HS2’s revised and postponed London Euston terminus has almost doubled to £4.8bn since 2020, according to the the public spending watchdog, with millions wasted on botched decisions.

The government announced last month that work on the high-speed line’s central London station would be paused. But the National Audit Office warned on Monday that the move would “lead to additional costs and potentially higher costs overall”.
