The IGD’s previous forecasts on UK food inflation have proved broadly accurate.
‘A Real Divide’
UK food price inflation reached its highest since 1977 in March last year at over 19%.
Though this official measure slowed to 8% in December, rising food prices remain a major strain on the finances of many households.
IGD’s head of economic and consumer insight Michael Freeman said, “The recent inflation figures highlight that the cost-of-living crisis is still real for many consumers.
"There is a real divide between mainstream society and those on the lowest incomes."
Household living standards have fallen over the past two years due to high inflation, contributing to the electoral challenge facing Prime Minister Rishi Sunak, who has suggested he will hold a national election in the second half of the year.
The news comes despite retailers introducing price cuts in late 2023 due to easing food inflation at the time.
Britain's overall inflation rate was 4.0% in December.
In November, the Bank of England forecast that the rate of inflation would exceed 3% throughout 2024. It will update its forecasts on 1 February.
The IGD report also said food businesses will need to keep abreast of a slew of upcoming policy changes this year.
