National Audit Office
Crossrail could cost up to £218 million more than the funding available, reports the National Audit Office in its latest progress report on the mega-project.
The NAO puts Crossrail’s forecast cost (not including new trains and depot) at £18.9 billion, compared with the 2010 budget of £14.8bn.
That is also some £1.9bn higher than when the NAO reported in May 2019.
It means the project would be 28% nominally more expensive than expected in 2010, as well as potentially three years late by the time it opens some time in 2022.
