Aldi is cheapest supermarket in July but Asda no longer best value larger shop, Which? finds
Aldi has been named the UK’s cheapest supermarket in July 2023 by Which?, while Asda has been knocked off its perch as cheapest for a larger trolley of items for the first time in three-and-a-half years.
The consumer champion’s monthly analysis involves comparing the average prices of a shop consisting of popular groceries at eight of the UK’s biggest supermarkets. Experts also look at a larger trolley of groceries at six supermarkets, as the discounters do not always stock big-brand products.
The cheapest supermarket for a smaller basket of goods this month was Aldi, where a basket of goods cost £71.22 on average across the month.
Fellow discounter Lidl was just behind Aldi, with a difference of £1.38 (£72.60 on average).
Waitrose was the most expensive this month, with a basket of groceries totalling £87.24 on average, which is 22 per cent more than Aldi – a difference of £16.02.
Which? also compared the cost of a larger trolley of 135 items – the original 38, plus 97 more. These items included a larger number of branded items, such as Andrex toilet paper and Cathedral City cheese, and did not include discounter supermarkets Aldi and Lidl, as they do not always stock some of these products.
This month, Morrisons was the cheapest for this larger trolley of groceries, pushing Asda into second place for the first time since January 2020. In July 2023, it cost £341.92 on average for this shop, beating the next cheapest, Asda (£342.14), by just 22p.
Waitrose was £34.74 more expensive than Morrisons, coming in at £376.66 or 10 per cent more, on average, for the trolley of comparable goods.
This latest pricing analysis from Which? demonstrates that shoppers can make considerable savings on their groceries depending on where they buy their food. However, even budget ranges at the discounters have risen in price significantly, and with most of the traditional supermarkets’ convenience stores failing to offer or stock budget lines, the consumer champion believes supermarkets must do more to help their customers.
Which? has found that while some good practice exists, many of the major supermarkets have not done enough to support their customers during the cost of living crisis.
Supermarkets could be doing more by ensuring smaller convenience stores stock a range of essential budget lines that support a healthy diet, especially in areas where they are most needed. Morrisons recently led by example by committing to stocking 40 of its budget items in its smaller convenience stores in the coming weeks.
Supermarkets also need to ensure unit pricing is clear so that customers can easily work out the best value products. This includes providing unit pricing on loyalty card prices.
Given the urgency of this cost of living crisis, Which? is calling on the government to act now and work with supermarkets to secure these changes that could make a real difference to millions of people struggling to put food on the table.
Natalie Hitchins, Which? Head of Home Products and Services, said:
“Households up and down the country are having their budgets squeezed by the cost of living crisis and our latest research shows that once again Aldi is the cheapest supermarket.
“For a larger trolley of items, Asda has been knocked off its perch as the cheapest option for the first time in several years with Morrison pipping it to the post for value.
“Which? believes that supermarkets are currently failing to adequately help shoppers during the current crisis. They must ensure everyone has easy access to basic, affordable food ranges at a store near them – including providing a range of essential budget lines that support a healthy diet in smaller convenience stores where they have them. They must also provide transparent and comparable pricing so people can easily work out which products offer the best value.”

- Every month, the consumer champion compares how much some of the UK’s biggest supermarkets charge for a basket and trolley of groceries, including everything from bread to toothpaste. Which? compares hundreds of grocery prices at Aldi, Asda, Lidl, Morrisons, Ocado, Sainsbury’s, Tesco and Waitrose to reveal the cheapest supermarket.
- For its ‘cheapest supermarket of the month’ analysis, Which? works out the average price for each item at each supermarket across the month, and adds this up to get an average trolley price for each store.
- Which? includes special offer prices but not multi-buys or loyalty discounts, to keep it as fair as possible. The shopping list combines branded items such as Heinz baked beans and PG Tips tea bags with own-label products, including milk and pasta. Of course, own-brand items aren’t exactly the same at different supermarkets, but Which? uses experts to ensure that the products are as comparable as possible based on a range of factors, including weight and quality.
- Which? launched its Affordable Food For All campaign calling on supermarkets to step up and help consumers keep food on the table. The consumer champion has defined how this can be achieved setting out specific steps supermarkets can take such as clear and transparent pricing and access to affordable food ranges across all stores.
