Between 2016 and this summer, the government has provided over £6bn of additional funding for departments and devolved administrations to prepare for EU exit. This has all been core funding, for any scenario.
In addition to this core funding, the Chancellor announced £2.1bn on 1 August 2019 specifically to prepare for leaving the EU without a deal.
Further to these allocations of funding, on 30 September 2019 the government reaffirmed its funding guarantee if the UK leaves the EU without a deal and should the EU cease to fund UK organisations after EU exit. This guarantee relates to UK organisations in receipt of certain EU programme funding. The total amount expected to be covered by the guarantee would be £4.3bn for this financial year.
