Grocery inflation is running at 13.9% over the 12 weeks to 2 October – meaning that the average annual bill was £643 more expensive, Kantar Worldpanel data shows.
It marked a sharp increase compared to a month ago when the rate was reported at 12.4%, adding £571 to the average annual bill.
Rising food prices have been a major factor behind recent upwards pressure on the consumer prices index (CPI) measure of inflation – currently standing at 9.9% – which tracks the extent of the cost of living crisis pain being felt by households.
