The extra number of pints bought during the last 16 knockout stage match could provide a boost to the economy of up to £18m, the trade association predicted.
Weekend game
However, the BBPA said that the taxman would be cheering the loudest when England play Colombia as the Chancellor could get an additional windfall, which could be as high as £2.7m.
If England beat Colombia and progress to the quarter finals of the World Cup, the BBPA predicts that an extra 8m pints would be bought during the match versus either Sweden or Switzerland. Pubs would also benefit from the fact that the game is on a weekend and would take place at 3pm on Saturday 7 July.
The BBPA said this would provide as much as a £24m boost to the economy and a windfall for the taxman as high as £3.6m from fans watching the match at their local.
Great British pub
The BBPA had already predicted that during the group stages of the World Cup, England fans would purchase up to 16m extra pints while watching England in their games against Tunisia, Panama and Belgium.
BBPA chief executive Brigid Simmonds said: “When it comes to watching the World Cup, only being at the game itself can compare with being in the pub. With the England team doing us proud and getting to the knockout stages of the tournament, fans will continue to pack out their local to cheer on the boys. It’s fantastic news for the great British pub!”
