Sales from pub and restaurant groups have plummeted 72.6% over Christmas, according to the Coffer Peach Business Tracker.
Trading for the five weeks from 30 November to 3 January revealed that drink-led hospitality venues have been the worst hit by the most recent lockdown.
Total sales for pubs and bars were down 83.7% and 87.2% respectively over the same period last year.
Food-led pubs and pub restaurants were down 78.2%, while group-owned restaurants saw total sales fall 57.9%.
However, sales from deliveries accounted for 23% of the overall sales for restaurant chains.
Karl Chessell, director of CGA, said: “Hopes that Christmas and New Year would help at least part of the market recoup a little of the income lost earlier in 2020 were dashed when the government started to impose increasingly severe tier restrictions across England in the run-up to the Christmas break, with further prohibitions for New Year, on top of the restrictions in place in Scotland and Wales.”
