Two major reports show whether Asda, Aldi, Tesco or Lidl are cheapest

Two new reports have revealed which is the current cheapest place to do your supermarket shopping with the winner changing depending on how the numbers are added up.

The latest figures based on the Consumer Price Index put one chain at the top according to a price-tracking app, while a major Which? survey crowns another big brand.

Which? has today announced that Aldi has maintained its position as the cheapest supermarket in the UK for August.

The price comparison looked at the cost for a trolley of 74 items, including groceries and household essentials, with Aldi coming in the cheapest at just £66.45 – £15.66 less than Tesco, a difference of 23.5%.

Julie Ashfield, Managing Director of Buying at Aldi, said: “We know that this is a difficult time for many and so we are incredibly proud to have maintained our position as the UK’s cheapest supermarket. We remain wholly committed to continuing to provide our customers with the best value products of any supermarket.”

Which? compared the prices of 74 branded and own-label items at Aldi, Asda, Lidl, Morrisons, Ocado, Sainsbury’s, Tesco and Waitrose every day in August.

It tracked the prices of everything from semi-skimmed milk and free-range eggs to Hovis wholemeal bread and Knorr vegetable stock pots to work out which supermarket was the cheapest, on average, across the month.

In an unconnected report the app Alertr, tracking the price of the 43 items outlined in the Government’s Consumer Price Index ‘shopping basket’ on a week-by-week basis, Asda was the cheapest place to shop last month for the fourth month in a row.

Andy Barr, co-founder of www.alertr.co.uk, said: “Despite the average cost of ASDA’s basket being more than last month’s, it has still managed to retain its title as the cheapest supermarket.”

Online price tracking website www.alertr.co.uk has been tracking the prices of 43 everyday items from the shopping basket on the Office for National Statistics’ Consumer Price Index (CPI) since 2019.

Included within the list are items such as eggs, milk and bread, as well as non-perishables like pasta, rice and cereal.

The prices across seven of the largest supermarkets are analysed, with discount retailers Lidl and Aldi not included due to the inability for customers to shop full ranges online.

Own-brand items (or their equivalent) were monitored in the research to give the most unbiased comparison of goods and their prices, with the exception of brands that all seven supermarkets stocked (e.g. Coca-Cola).
