Non-food prices rose for the first time in 15 months in March, according to the British Retail Council Shop Price Index out today.

Overall shop price inflation rose to 1.4% from 1.1% in February, the study said.

But while food inflation was unchanged at 3.5% in March, non-food inflation rose 0.2% in March, compared with a 0.4% fall in February.

“Non-food prices have edged into inflationary territory for the first time in 15 months, driven by gradual growth across a number of categories rather than any one seeing a substantial increase,” said BRC director general Helen Dickinson.

“Food inflation is unchanged since February, but this is primarily due to a decrease in prices for tinned and packet goods balancing out a fresh food rise,” she added. “There are still price pressures which will continue to work through, but I would expect food inflation to remain fairly steady in the medium term.”
