House of Commons Library report: Brexit – The Exit Bill
4 July 2018
After the UK leaves the EU, it is expected to make a contribution towards the EU’s outstanding financial commitment. The UK Government estimates that the settlement will cost around £35 billion-£39 billion.
However, it is very difficult to put definitive figures to the settlement as the actual payment will be based on outturns – rather than current estimates – which depend on future events.
This is according to the July 2018 report from House of Commons Library on the the exit bill.
