Kantar Worldpanel also revealed market growth had bounced back to 2.8% from the historic low of 1.7% recorded in the last period.
“The low grocery price inflation this period will be welcome news for household budgets,” said consumer insight analyst Fraser McKevitt.
“The outlook is positive as we predict continuing sub 1% levels into the near future, providing some relief for cash-strapped consumers,” he added.
