A total of £5.5 billion has been spent between financial years 2009/10 and 2017/18, covering both HS2 Ltd and Department for Transport expenditure. We are unable to report spend beyond the end of 2017/18 financial year until the HS2 Ltd and DfT annual accounts are published. This spend includes Land & Property and HS2 Ltd core programme group expenditure.
Substantial construction spend will be seen across the whole of the UK. The Infrastructure and Projects Authority published a report in 2018* on UK transport investment allocated across regions, with analysis of where HS2 construction costs were expected to fall. The analysis takes a cost approach, apportioning spending according to the full length of route included in each region, and using industry benchmarks to weight the sections of route involving tunnels to reflect the increased cost of tunnelling.
