New UK cheapest supermarket revealed out of Asda, Tesco and Aldi as major brand knocked off top spot

For a bigger shop of 159 items, a Tesco shop with a Clubcard came out cheapest at £399.73 - a saving of £9.63 compared to the average £409.36 shop at Asda

Tesco has beaten Asda to be named cheapest supermarket for a big shop in the latest Which? price comparison.

For a bigger shop of 159 items, a Tesco shop with a Clubcard came out cheapest at £399.73 for November 2024 - a saving of £9.63 compared to £409.36 at Asda. Waitrose was the most expensive last month, costing £452.09. Asda has taken the crown for cheapest large shop every month since July 2024. Meanwhile, Aldi was once again named by Which? as the cheapest supermarket for a smaller shop.

A shop of 55 items cost £97.89 on average at Aldi last month - this is 45p more compared to £98.34 at rival Lidl, or 38p more for shoppers who are signed up to Lidl Plus, where the typical shop came to £98.27. Aldi and Lidl are not included in the larger shop comparison as they have a smaller range of products compared to the other supermarkets.

Waitrose was the most expensive supermarket for a smaller list of items this month too, totalling £123.32 on average - a difference of £25.43 compared to Aldi. The list of 55 items included both branded and own-brand items, such as Birds Eye Peas, Hovis bread, milk and butter.

The Which? analysis includes special offer prices and loyalty prices where applicable, but not multibuys. For the smaller shop, Tesco Clubcard members would have paid £105.61 on average - while without a Clubcard, the Tesco shop cost £108.45. For those using a Sainsbury’s Nectar card, November’s shopping list of items averaged £106.71, which is £8.82 more than at Aldi.

Without a Nectar card, the same items at Sainsbury’s cost £112.06. This latest pricing analysis from Which? demonstrates that shoppers can make considerable savings on their groceries depending on where they buy their food.

Harry Rose, Editor of Which? magazine, said: “Our latest monthly analysis once again sees Aldi crowned as the UK’s cheapest supermarket, however Lidl remains hot on its discounter rival’s heels. With Christmas just around the corner, people are looking to cut costs where they can. Our analysis shows that by switching supermarkets consumers could save up to 21%, highlighting the advantages of shopping around where possible."
