Aldi has once again been named the cheapest supermarket in the UK - but have had to share their crown with budget supermarket rival Lidl.

Consumer comparison site Which? compared 19 everyday items sold by all major UK supermarkets throughout January, including food, drink and household products.

Aldi and Lidl were found to be joint-cheapest, at £18.45, while Waitrose was found to be the most expensive place to shop, with equivalent items costing £24.79.

Julie Ashfield, Managing Director of Buying at Aldi, said: “We are delighted that yet again Which? has named Aldi as the UK’s cheapest supermarket.

"We are proud to be helping families throughout the UK by consistently providing the cheapest possible prices across our entire range of products.”

What about the non-discount supermarkets? 

The top four UK supermarkets - Tesco, Asda, Sainsbury’s and Morrisons - were also included in the survey, alongside Ocado.

Which? also compared bigger supermarkets and compared shopping totals based on a fuller trolley consisting of 87 items.

These items included the original list of 19 items and a greater selection of brand products, including Branston baked beans and Andrex toilet roll.

Aldi and Lidl were not included in this comparison as it is typically more difficult to find branded products in store.

In their absence, Asda came out on top for the month, with a price of £160.08 for the trolley of groceries - £9 cheaper than their nearest rival, Sainsbury’s.

Sainsbury’s were the second cheapest with a price of £169.40 while Morrisons (£171.99) and Tesco (£176.47) followed.

Ocado was the most expensive of the bunch in January, costing a hefty £22.19 more than Asda for the same items at £182.27.

High-end Waitrose was also a pricey prospect at £181.66 on average.
