Aldi has been named the UK’s cheapest supermarket by Which?, as the consumer champion found shoppers could save almost £27 on a basket of items there compared to the most expensive store. Which?’s analysis involved comparing the prices of a shop consisting of 48 popular groceries at eight of the UK’s biggest supermarkets.
The cheapest supermarket was Aldi, where the basket of goods was £77.21 on average. The same shop at Waitrose was £104.11 on average, making it £26.90 more expensive in comparison. Which? also compared the cost of a larger trolley of 149 items – the original 48, plus 101 more. This shop 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, which do not always stock some of these products.
Asda cost the least for this larger trolley of groceries, continuing its winning streak, which started in January 2020, as the cheapest traditional supermarket. It cost £355.34, on average, for this shop, beating the next cheapest, Sainsbury's (£366.83), by £11.49. Waitrose was an eye-watering £38.03 more expensive than Asda, coming in at £393.37, on average, for the trolley of comparable goods.
