New UK cheapest supermarket revealed out of Tesco, Asda and Aldi as retailer knocked off top spot
Asda has beaten Tesco to be named the cheapest UK supermarket in February 2025 for a large shop.
Which? has revealed the results of its monthly food price comparison, and Asda came out cheapest at £512.30 for a bigger shop of 206 items, beating Tesco with a Clubcard by £3 (£515.30). It comes after Asda brought back Rollback scheme, which it says has seen prices of more than 4,000 products slashed by an average of 25%.
The list of 100 items included both branded and own-brand items, such as Birds Eye Peas, Hovis bread, milk and butter. Aldi and Lidl are not included in this comparison as they have a smaller range of branded products compared to the other supermarkets.
But once again, Aldi was named the cheapest UK supermarket for a smaller shop, where a list of 100 items cost £182.64 on average across last month. Rival discounter Lidl cost only £1.87 more with the supermarket’s loyalty scheme Lidl Plus (£184.51) and £2.30 more without (£184.94).
For the smaller shop, Tesco Clubcard members would have paid £205.31 on average – while without a Clubcard, the Tesco shop cost £212.54. For those using a Sainsbury’s Nectar card, the list of items averaged £213.46, while without a Nectar card, the same items at Sainsbury’s cost £225.20.
Waitrose was the most expensive supermarket for the smaller and larger shop, costing £245.79 and £585.10, respectively. Reena Sewraz, Which? Retail Editor, said: “Our latest monthly analysis once again sees Aldi crowned as the UK’s cheapest supermarket, however, Lidl remains close behind its rival. It was also a good month for Asda, as it held on to the top spot as the cheapest supermarket for a bigger list of groceries.
“With people still feeling the effects of food inflation and with prices forecast to rise again, people are likely looking to cut costs where they can. Our analysis shows that by switching supermarkets consumers could save up to 26 per cent, highlighting the advantages of shopping around where possible.”
