Like-for-like grocery price inflation in Ireland accelerated to 4.28% in the 12 weeks to September 6, 2026, rising from 3.87% in August, according to market data published by Worldpanel by Numerator on September 21.

The increase marks the first rise in grocery inflation after four consecutive months of moderation, following a steady decline from an April rate of 6.7%. Analysts noted that while the percentage point increase is modest, it places renewed financial pressure on household food budgets alongside climbing domestic energy tariffs and higher interest rates.

Take-home grocery sales expanded by 5.5% year-on-year in the four-week period to September 6. Irish consumers recorded 44.6 million store trips during the period—an increase of 1.65 million visits compared with the previous month—as households stocked up on staples as back-to-school routines resumed.

According to Emer Healy, business development director at Worldpanel by Numerator, back-to-school preparation contributed to increased demand for branded goods. Spending on branded items rose by 13% in value, adding €216 million to the market, led by higher demand for biscuits, savoury snacks, breakfast bars, sliced meats, and yoghurts.

Despite the growth in overall spending and trip frequency, value-seeking behaviour remained prominent among shoppers. Irish consumers allocated €820 million to promotional items over the 12-week period, with discounted products accounting for roughly one-fifth of overall market spend as households continue to manage lingering cost-of-living pressures.
