Which? has revealed Aldi as the UK's cheapest supermarket for the latest month, with a basket of 93 popular grocery items costing just £158.05. The consumer group's monthly study compared prices across eight major retailers, including own-brand and branded products such as milk, cheese, and sliced bread.
Discount Leaders and Rivals
German discounter Lidl followed closely behind, with the same shopping list totaling £160.70. Asda also performed well, beating the loyalty prices of Tesco and Sainsbury's. Asda's everyday prices for the basket came to £185.81, which was cheaper than Sainsbury's Nectar Card prices at £187.86. Tesco's Clubcard prices were higher still, at £188.45.
Loyalty Price Gaps
For shoppers not enrolled in loyalty schemes, the cost was significantly higher. Tesco's regular prices reached £195.63, matching an identical shop at Morrisons, while Sainsbury's regular prices were even more expensive at £197.85. Waitrose remained the most expensive, with customers paying £226.95—£68.90 more than the cheapest store.
Expert Insight
Reena Sewraz, Which? Retail Editor, hopes shoppers will consider where they buy groceries, noting that despite inflation remaining "stable for now," households may be cautious about potential price hikes. She added: "The discounters are still the cheapest supermarkets, while Asda beats Sainsbury’s and Tesco’s loyalty scheme prices according to our analysis."
Which? noted that during the study period, 25 products were on loyalty discount at Sainsbury's, while Tesco had 23 items reduced for Clubcard members. In contrast, no loyalty discounts were available at Morrisons, Waitrose, or Lidl for the included products.
