The impact of Brexit on London's economy - 2023 report

Brexit has been exerting pressures on the London and UK economies to the detriment of long-term growth and prosperity.

GLA Economics has used a synthetic control methodology to measure the impact of Brexit-related effects on London’s economy.

The analysis finds that London’s Gross Value Added (GVA) was 6.2% (or £32 billion) lower in 2019 than it would have been had the UK voted to remain in the EU back in 2016.  This is nearly £9,500 of forgone income for every household in London.
