Grocery price inflation has reached 9.9% over the past four weeks, the second highest level ever recorded by Kantar.
As a result, with grocery price inflation at almost 10%, customers are now facing a £454 increase to their annual grocery bills.
According to Kantar’s figures, grocery sales grew by just 0.1% in the 12 weeks to 10 July 2022, due to the ongoing cost-of-living crisis and rising inflation.
Kantar’s head of retail and consumer insight Fraser McKevitt said as prices rise, shoppers are adjusting their behaviour, resulting in more customers turning to own-branded products to drive down the cost of their weekly shop.
“Supermarkets’ own lines are growing by 4.1% this period, while sales of branded items have fallen by 2.4%,” he said.
“It’s a complex picture and the grocers are busy negotiating with their suppliers to mitigate impact at the tills as far as possible. We’ve seen this play out in the headlines in recent weeks, with some well-known brands temporarily disappearing from supermarket shelves over pricing disputes.”
This follows Tesco and Heinz’s public spat after the FMCG brand suspended supplying to the Big 4 grocer over price disputes.
