The heatwave this summer provided a boost to the grocery market in Ireland.

The latest figures from Kantar Worldpanel for the 12 weeks to the middle of August show a €30m uplift in consumer spend compared with the same period last year.

Barbecue items, ice cream and cider sales led the growth.

Aldi posted the strongest growth of all the multiples growing 26.6%, bringing it to a 7.4% total market share.

Lidl also recorded impressive growth of 14.8%, giving it a 7.7% market share.

Tesco has seen a drop in sales compared with a strong performance last year, with fewer customers spending less in store.

Its market share was down 4.7% to stand at 27% of the market.

The market share for Dunnes Stores was almost unchanged at 21.1%, a drop of 0.2% on last year.

"SuperValu has also performed strongly over the summer period, attracting new shoppers through the door. This has helped boost its share from 19.5% last year to 19.8% now with sales growth of 3.1%," David Berry, commercial director of Kantar Worldpanel said.

"Interestingly, there has been no negative effect for Superquinn following the recent announcement that the stores will be renamed as SuperValu, with sales and market share remaining in line with last year," he added.

The data also included a measure on grocery price inflation which stood at 5.5% for the 12-week period, up from 4.6% seen in the last period.
