Aldi has beaten rival Lidl to be named the cheapest UK supermarket in April 2024, according to Which? research.

Of the eight biggest supermarkets in the UK, Aldi was the cheapest for a basket of 67 items. The basket cost £112.90 on average across the month.

Fellow discounter Lidl was just behind Aldi in April, with the basket costing £2.33 more (£115.23 on average).

Waitrose was found to be the most expensive supermarket at £144.13 – a difference of £31.23 compared to Aldi.

The 67 items included a number of both branded and own-brand items, such as Birds Eye garden peas, Heinz baked beans, Hovis bread, milk and butter.

The analysis includes special offer prices but not multi-buys or two-tier loyalty prices, which are only available to loyalty scheme members.

The latest pricing analysis from Which? demonstrates that shoppers can make considerable savings on their groceries depending on where they buy their food.

Which? retail editor Ele Clark commented: “As food costs continue to weigh heavily on household finances, it’s unsurprising many people are opting to shop at discounters to save money, especially as shoppers could stand to make significant savings.”

Aldi UK managing director of buying Julie Ashfield stated: “We are as committed as ever to maintaining our position as the UK’s cheapest supermarket. We’ve invested £125m in price cuts so far in 2024, further demonstrating that we’ll continue to do whatever it takes to keep grocery prices as low as possible for the millions of customers who shop with us.”

The retailer recently initiated a nationwide campaign to engage the UK public in selecting optimal sites for upcoming store launches.
