Aldi has been named the UK’s cheapest supermarket in January by Which?, as the consumer champion found shoppers could save almost £26 on a basket of items there compared to the most expensive store.
The consumer champion’s analysis, which involves comparing the prices of a shop consisting of 45 popular groceries at eight of the UK’s biggest supermarkets, is done on a monthly basis.
The cheapest supermarket was Aldi, where the basket of goods was £82.03 on average. The same shop at Waitrose was £107.71 on average, a difference of £25.68.
Which? also compared the cost of a larger trolley of 144 items – the original 45, plus 99 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, given that they do not always stock some of these products.
Asda was the cheapest for this larger trolley of groceries, continuing its winning streak, which started in January 2020, as the cheapest of the bigger supermarket chains. It cost £363.29 on average for this shop, beating the next cheapest, Sainsbury’s (£375.84), by £12.55.
Waitrose was an eye-watering £45.43 more expensive than Asda, coming in at £408.72, on average, for the trolley of comparable goods.
This latest pricing analysis from Which? demonstrates that shoppers can make considerable savings on their grocery budget depending on where they buy their food. However, with even budget ranges and prices at the discounters rising significantly, the consumer champion believes supermarkets must do more to help their customers.
Which? recently launched its Affordable Food For All campaign, calling on supermarkets to provide the support people around the country desperately need in order to keep food on the table during the ongoing cost of living crisis.
Reena Sewraz, Which? Retail Editor, said:
“Nobody wants to pay over the odds for their weekly food shop, especially as the cost of living crisis stretches household budgets for millions of people.
“Our findings show that while prices are going up, some supermarkets are significantly more expensive than others. As well as choosing a supermarket that is cheap overall, other ways to save include swapping from branded to supermarket own-brand products, sticking to a shopping list, and resisting the temptation to pick up special offers you may not need.”

- Every month, the consumer champion compares how much some of the UK’s biggest supermarkets charge for a 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 Kenco coffee, Oxo stock cubes and PG Tips tea bags with own-label products, including onions and milk. 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? recently 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 in a 10-point plan that sets out specific steps supermarkets can take in three main areas: clear and transparent pricing, access to affordable food ranges across all stores and more targeted promotions for consumers who are struggling.
