In the 2017 Autumn Budget, the Treasury said only that it will "continue to work with Transport for London on developing fair and affordable plans for Crossrail 2, including through an independent review of funding and financing". On 2 March 2018, the UK's Transport Secretary, who represents a seat centred on a prospective terminus of one of the branch lines (Epsom and Ewell), announced Mike Gerrard would lead the Treasury's required Independent Affordability Review, which is expected to conclude in the summer of 2018.
