Britons made over 79 million extra grocery shopping trips in the four weeks to March 21 year-on-year as they stocked their 'pandemic pantries', driving a 20.5% jump in supermarket sales, industry data published on Tuesday showed.
Market researcher Nielsen said British consumers spent an additional £1.9 billion pounds on groceries.
The data showed that in the week ending 21 March, two days before Prime Minister Boris Johnson announced the full UK lockdown to try to contain the coronavirus spread, sales rose 43% compared to the same period last year.
Basket Increase
Nielsen found that in the four-week period shoppers typically added just one extra item to their basket during each shopping trip, with the average shopping basket increasing from ten items to eleven items, and average basket spend rising from £15 pounds to £16 pounds.
"With households making almost three extra shopping trips in the last four weeks, this small change in individual shopping behaviour has led to a seismic shift in overall shopping patterns," said Mike Watkins, Nielsen’s UK head of retailer and business insight.
"As well as increased store visits, consumers opted to shop online - many for the first time. However, unlike stores there is a finite capacity for online grocery shopping, due to warehouse capacity and available delivery slots, and this will have limited the growth of online sales.”
Nielsen data showed that in the last week of February and the first week of March, shoppers focused on "stockpiling" necessities, such as medicines, cleaning supplies, pet care items and ambient groceries, such as pasta and rice. This continued through to the third week, with a consistent rise in these "pandemic pantry" items.
Frozen Food Sales
In the week ending 21 March, many shoppers had already filled their cupboards with the necessities, so they began to fill their freezers too. Sales of frozen food during this week rose by 84% compared to the same period last year.
This was also the week in which the government announced the closure of pubs and restaurants, resulting in a 67% surge in beer, wine and spirits sales.
Nielsen said all UK supermarkets experienced significant growth in sales over the four week period, with market leader Tesco's sales up 20.1% and those at Sainsbury's , Asda and Morrisons up 22.4%, 17.2% and 19.3% respectively. Online grocery sales increased 14% year-on-year.
