Aldi has been confirmed as the UK's cheapest supermarket

Data showed an average basket of groceries would cost you £20 less compared to the most expensive, Ocado.

Aldi has been crowned as the cheapest UK supermarket for the twelfth month in a row.

Experts from Which? compared the prices of a basket of 40 popular grocery items in May, including Heinz baked beans and Dolmio sauce, as well as own-brand products like apples and lettuce.

They found that the total average cost was the lowest at Aldi with an average cost of £68.60 at Aldi. Meanwhile, the same shop at Waitrose will cost you, on average, £86.41, which is an additional £18.31.

In May, Lidl came in second behind Aldi, with the shop costing £70.51, and Asda followed at £76.45. According to Which?'s analysis, Morrisons, Ocado, and Waitrose were the most expensive supermarkets in May.

Sainsburys and Tesco were the closest in price and sat in the middle of the table at £77.13 and £77.56, respectively.

Which? compares supermarket prices by working out the average price for each grocery item across the month in each store, then adding them up to get an average basket price.

Julie Ashfield, Managing Director of Buying at Aldi UK, said: 'We know it is a difficult time for many and we’re proud to have consistently been the cheapest supermarket in the UK – supporting our customers when it matters the most.'

However, when comparing the cost of a larger trolley of 131 items, Asda came out as the cheapest at £332.40. This time, more branded items were taken into account, such as Andrex toilet paper and Cathedral City cheese, which you cannot always get in Aldi or Lidl, so they were left out of the comparison.

Morrison's was the second cheapest, with the shop coming to £334.47. Unsurprisingly, Ocado and Waitrose came out as the most expensive in this comparison too, with the trolley of items costing £354.90 and £363.99, respectively.

Supermarket prices have continued to rise, with Which?'s tracker indicating that prices were, on average, 17.1% higher in April 2023 compared to the year before. Out of 20 categories, cheese continues to be the fastest rising in price.

Ele Clark, Which? Retail editor, said that the price of food and drink is 'continuing to soar', as people suffer through the 'worst cost of living crisis in decades'.

'It's no surprise to see many shoppers turning to discounters like Aldi and Lidl when our research shows they could make savings of more than £18 on a basket of everyday groceries,' Clark stated.
