The figures show that both Aldi and Lidl are continuing to post impressive performances, with sales up by 15.1% and 12.3% respectively over the past year.

Lidl has attracted 41,000 new shoppers this quarter as shoppers were enticed by back-to-school offers. Meanwhile, Aldi’s sales have been boosted as more shoppers chose to visit the retailer for their main grocery shop, with customers increasing their spend by €1.20.

David Berry, commercial director at Kantar Worldpanel, explains: “Aldi and Lidl have both enjoyed record levels of market share over recent months and this strong performance has continued thanks to increased footfall over the past 12 weeks [ending 14 September]."

Dunnes Stores has posted the strongest results among the larger grocers, enjoying increased sales for the fifth successive month. A rise in the number of round euro priced branded goods on sale has drawn customers into its stores, contributing an additional €15m in sales for the retailer.

Berry commented: "Some 37% of branded goods sold in Dunnes are now on sale at a clear round euro price point, compared with just 32% last year.”

Tesco remains Ireland’s number one grocery retailer despite a dip in market share from 26.7% to 25.2% year on year. Shoppers are continuing to choose Tesco, upping the number of trips they make to the leading grocer. However customer in-store spending has decreased by almost €2 on average over the past year.

Meanwhile, SuperValu has attracted an extra 40,000 households through its doors this year, boosted by its own brand offering. The trade-off is that reduced customer spending in store has meant a slight dip in sales for the retailer compared with last year. On average, SuperValu customers have reduced their spending by €16 over the past 12 weeks by choosing more own brand products.
