Aldi has been named the UK’s cheapest supermarket for March, coming out £20 cheaper than Waitrose but just 25p less expensive than Lidl.
According to recent data from consumer watchdog Which?, a basket of 41 grocery items at Aldi cost £72.54 on average across the month, compared with £92.55 at Waitrose and £72.79 at Lidl.
Sainsbury’s was third cheapest at £80.27, then Tesco with £81.58, which was followed by Asda and Morrisons at £81.88 and £83.63, respectively.
Which? also analysed the cost of a larger trolley of 137 grocery items, made up of the original 41, plus 96 more.

From that dataset, Asda came out as the cheapest for this trolley of groceries, costing £343.91 on average. In second place was Sainsbury’s, which was £9.25 more expensive at £353.16.
Meanwhile, the most expensive supermarket on this metric was Waitrose again. Its total for a larger trolley was £41.83 more expensive than Asda, coming in at £385.74, on average, for the same range of products.
A Waitrose spokesperson said: “We continue to work with our suppliers to keep prices as low as possible with more price cuts to come, but remain equally committed to industry leading animal welfare standards, paying our farmers fairly and providing outstanding quality products.”
Which? said the findings demonstrated that shoppers can make considerable savings on their groceries depending on where they buy their food. However, it said many of the major supermarkets had not done enough to support their customers during the cost of living crisis.
“We know people are suffering through the worst cost-of-living crisis in decades and the price of food and drink has skyrocketed no matter where you shop,” Which? Retail editor Ele Clark said.
“However, our monthly supermarket analysis shows you could save £20 on a basket of everyday groceries at the cheapest supermarket compared to the priciest one.”
Clark added: “Supermarkets aren’t currently doing enough to help customers. Which? believes the big retailers have a responsibility to ensure everyone has easy access to basic, affordable food ranges at a store near them, and to provide transparent pricing so people can easily work out which products offer the best value.”
