Aldi has been named the cheapest UK supermarket for June 2026, retaining the title for the sixth consecutive month, according to consumer champion Which?. Shoppers can save up to £66.54 on a basket of 95 items compared to the most expensive retailer, Waitrose.
Price Comparison Details
Based on a shop of 95 popular branded and own-brand products, including milk, cheese and Hovis sliced bread, Aldi shoppers paid an average of £163.34. Lidl with Lidl Plus discounts came second at £164.79, while without the loyalty scheme the total was £164.92 – a difference of just 13p. Asda ranked fourth at £190.39, followed by Sainsbury’s with Nectar at £193.30, Tesco with Clubcard at £194.67, and Morrisons with More at £198.41. Waitrose was the most expensive at £229.88, a difference of £66.54 or nearly 41% more than Aldi.
Loyalty Card Impact
The analysis highlighted the savings from loyalty cards. Which? found that a loyalty card saved an average of 2.97% at Tesco and 5.17% at Sainsbury's, while at Lidl the saving was just 0.08%. Lidl changed its loyalty scheme in May, shifting from reward coupons to a points system where each pound spent earns one point, aligning with Nectar and Clubcard. Tesco recently introduced a Clubcard for 16- and 17-year-olds after campaigners urged supermarkets to lift age restrictions.
Grocery Price Inflation and Promotions
Grocery price inflation fell to 3% in the four weeks to June 14, according to Worldpanel by Numerator. Promotions accounted for 30.4% of sales last month, up from 28.4% a year ago. With the FIFA Men's World Cup underway, deals on beer, cider, snacks, crisps and chilled pizza have surged, as retailers compete for customers. Fraser McKevitt, head of retail and consumer insight at Worldpanel, said: “Nearly a third of all grocery spending is now on promotion, and that upward streak shows no sign of breaking. Combined with strong online growth, it points to shoppers who know what they want and are increasingly confident about where and how to find the best deal. In short, retailers are having to compete hard for that summer shop.”
