ALDI has again beaten its rival Lidl as the UK’s cheapest supermarket, according to consumer website Which?.

It used an independent price comparison site to track thousands of grocery prices.

The survey of Aldi, Asda, Lidl, Morrisons, Ocado, Sainsbury’s, Tesco and Waitrose found out how much each was charging for everyday items through the year.

Aldi regained its crown as the cheapest in all 12 months of the year for a typical shopping list of 56 groceries.

According to the study, shoppers at the German discounter saved an average of £393 over the year compared with customers at Waitrose — the most expensive alternative.

Lidl came a close ­second, with the same shopping list costing £1.19 more (£101.48) with its loyalty scheme Lidl Plus.

Harry Rose, editor of Which? magazine, said: “Our research shows Aldi has retained its crown as the UK’s cheapest supermarket in 2024.

“After the added expense of the festive period, many households will be looking to cut costs.

“Our analysis shows that by switching supermarkets, shoppers can make significant savings, highlighting the advantages of shopping around where possible.”

Waitrose was the most expensive supermarket for a larger trolley of items every month in 2024, apart from September.

In December, a Waitrose shop cost a total of £458.12 on average.
