German discounter Lidl has been crowned the UK’s cheapest supermarket of 2020. Aldi followed close behind in the Which? Rankings, which tracked the prices of 45 popular products in eight major supermarkets between January and December 2020. The average price of each item was calculated over the year and the total average cost of all 45 items in the “trolley”, taking into account the weight and quality of items. This was the first time Which? has included Lidl and Aldi in its annual study, which now includes own-label items as well as branded ones.
Lidl’s basket cost £42.67 on average, 34p less than its rival Aldi. Asda was the third-cheapest supermarket (£48.71). Waitrose was the most expensive supermarket in the study (£68.69). Which? also found marked price differences between own-label products at Waitrose and Lidl. Online retailer Ocado was the second most expensive supermarket in the study (£66.83), followed by Sainsbury’s (£56.38).
