The average annual grocery bill has increased by more than €1,000 to €8,071 this year, according to figures released by consumer data specialist Kantar.

The company points out that grocery inflation in Ireland, at 14.7%, has now risen higher than in the UK, where it is at 14.1%.

While the total amount shoppers are spending is rising, survey results show that people continue to increase the share of value supermarket labels in their weekly shop.

Looking ahead to the busy Christmas season, Kantar predicts that the value of grocery purchases will hit €1.25bn in the period for the first time ever.

Brussels sprouts are bucking that trend, with purchases of the windy vegetable expected to drop almost €200,000.

“Despite inflationary and other pressures, Irish shoppers are still stocking up on festive treats this year," senior retail analyst at Kantar Emer Healy said.

Dunnes Stores remains the most popular retailer, holding 23.3% of the market. Aldi and Lidl hold a combined 25.2%.
