Echoing data from rival market researcher Kantar last week, NIQ said German owned discounters Aldi and Lidl remained the fastest growing grocers with sales growth of 22.2 per cent and 18.7 per cent respectively over the 12 weeks to June 17.

“It’s no surprise that online grocery sales have taken a bit of a hit as there was less of a need to order in a big grocery shop. We expect to see supermarket volumes continue to improve slowly, as food inflation peaks. However, what shoppers buy and where they shop will continue to be strongly influenced by the continued squeeze on disposable incomes,” Watkins added.

“This means that spending over the next few months is still going to be focused on essential needs but as we continue to enjoy the sunshine this summer, there’ll be an increase in impulse spending on cold drinks and treats which is an upside for supermarkets in general.”
