Aldi and Lidl price gap widens according to Worldpanel data

Data from Worldpanel by Numerator indicates that the price gap per unit between discounters Aldi and Lidl has expanded over a two-year period. The average price per unit (AUP) is currently 1.57 pounds at Aldi compared to 1.72 pounds at Lidl, representing a relative difference of 9%, up from 6% two years ago.

The absolute difference in price per unit has grown from 10 to 15 pence. The report notes that these figures are derived from scanning consumer shopping baskets rather than shelf labels, meaning the data reflects both retailer pricing and consumer purchasing habits, such as the selection of premium or fresh products.

While Aldi maintains a lower average price per unit, Lidl has shown a year-on-year sales growth of 7.1%, compared to 0.4% for Aldi. Aldi currently holds a market share of 10.5%, while Lidl stands at 8.6%.
