The month of May, with two bank holidays and VE Day, saw an estimated 14 million more pints sold in pubs compared to a month without them, the BBPA estimates.
VE Day itself is estimated to have brought in up to one million extra pints sold in pubs thanks in part to the licensing hours extension which allowed them to stay open until 1am.
The additional pints mean the sector delivered an extra £69m in sales for the economy and generate £11.5m in VAT and £6.5m in beer duty compared to a month with no bank holidays or VE Day.
The boost comes as the sector wrestles with a barrage of extra tax and fees following the April cliff-edge which is costing the industry an extra £853m, the BBPA said.
The new statistics come after the BBPA revealed the average price of a pint has broken the £5 barrier for the first time, partly due to rising costs placed upon the sector.
The BBPA is urging the Government to do this by permanently rebalancing the business rate system, reviewing chaotic EPR costs, mitigating new employment fees, and ensuring the Employment Rights Bill doesn’t remove flexibility for the sector.
Emma McClarkin, chief executive of the British Beer and Pub Association, said: “Many of us chose to spend our local pub, a home away from home, as the perfect location to spend the sunny long weekends and to celebrate VE Day.
“These figures demonstrate how vital such occasions are to our sector, which is battling new costs including higher business rates bills, unfair and chaotic packaging fees, and soaring new employment costs.”
