Grocery price inflation has climbed again to reach 17.5% over the four weeks to 19 March 2023, a new record based on Kantar’s market data. Households are now facing an £837 increase in their annual bills if they don’t change their shopping behaviours. Take-home grocery sales more widely grew by 8.6% over the 12 week period.
“Unfortunately, it’s more bad news for the British public, who are experiencing the ninth month of double-digit grocery price inflation,” said Fraser McKevitt, head of retail and consumer insight at Kantar. “However, shoppers are taking action and clearly hunting around for the best value. Footfall was up in every single grocer this month, with households going to the shops just over four times per week in March. Apart from Christmas, that’s the highest frequency we’ve seen since the start of the pandemic.
“The supermarkets are also tackling grocery price inflation, battling it out to demonstrate value and get customers through their doors. This is a fiercely competitive sector and if people don’t like the prices in one store they will go elsewhere, with consumers visiting three or more of the top 10 retailers in any given month on average.”
