Grocery price inflation reached 5.2% in July, its highest level since January 2024.

The figures from Worldpanel also revealed a rise in food prices could add £275 to household annual grocery bills.

Fraser McKevitt, Worldpanel head of retail and consumer insight said: “Just under two-thirds of households say they are very concerned about the cost of their grocery shopping, and people are adapting their habits to avoid the full impact of price rises.

“Own-label products continue to outperform brands, growing by 5.6% versus 4.9%. These inflation worries aren’t just changing what we buy, but how we prepare it too, nearly seven in ten dinner plates now have fewer than six components.”

The data also showed, the recent warm weather led to increased drinks sales, with iced coffee sales rising by 81%, while ice cream and sorbet sales went up by 9%.

There is also a growing trend of no-alcohol and low-alcohol drinks, which saw their sales rise by 21%.
