Brexit added almost £6bn to UK food bills in the two years to the end of 2021, affecting poorest households the most.

London School of Economics (LSE) researchers say the cost of food imported from the EU shot up because of extra red tape, adding £210 to the average household food bills over 2020 and 2021, 

Since low-income families spend a greater share of their income on food, the impact of Brexit on their purchases was disproportionately greater, they said.

Lord Frost’s Brexit trade deal signed at the end of the transition period in December 2020 ensures trade is tariff-free with the EU but created trade barriers in the form of customs, rules of original paperwork and regulatory standards checks for agri-food products.

In 2015, the year before the referendum, 77% of food imports were from the EU.
