In the 12 weeks to 17 May, Irish grocery price inflation stood at 5.5% compared with the same 12-week period last year, according the latest Worldpanel by Numerator data.

This is based on over 30,000 identical products compared year on year in the volumes bought by Irish shoppers, so it excludes the impact of behaviour change by shoppers to avoid higher prices.

This is the slowest rate of increase with like-for-like grocery prices since July 2025.

Over the four weeks to 17 May, take-home grocery sales increased by 2.8%, though shoppers made fewer trips to the stores, averaging 22.8 visits, one fewer than the previous month.

Market share

Dunnes hangs on to top position for grocery sales over the past 12 weeks with 23.8% market share, but Tesco is close behind on 23.7%, with Supervalu in third place with 19.6%.

Discounter Lidl has increased its market share to 14.8%, up 0.4 percentage points compared with the previous 12 weeks and a new record.

Meanwhile, Aldi increased its market share slightly and now has 11% of the Irish grocery market.

Branded products recorded a strong performance in this quarter, growing 9.4% in value and adding €159m in revenue during this period, with own brand more modestly at 2.7% adding an extra €46.6m of value.
