May 2023: UK’s cheapest supermarket revealed.

Every month, we bring you the UK’s cheapest supermarket, according to consumer website Which?.  

Last month, we revealed the cheapest supermarket for April 2023 – excluding discounted shops Aldi and Lidl – was Asda. 

This month we are back, bringing you the cheapest place to buy groceries in May 2023. 

And the winner is… 

Aldi! Aldi tops the cheapest supermarket list for the 12th month in a row.

Every month, the analysis by Which? compares the prices of a basket of 39 popular grocery items at eight of the UK’s biggest supermarkets. The consumer champion found that in April, shoppers could save a tidy £17 on a basket of items from Aldi, compared to the most expensive store.  

The results showed that the basket of 39 goods from Aldi cost £68.60, on average, across the month. Lidl wasn’t too far behind, with a price difference of £1.91 (£70.51). The gap between supermarkets has increased however, with results for April showing just a 65p difference. 

Waitrose came in as the most expensive supermarket, coming in at an average of £87.91 over the month – a staggering difference of £18.31 more. 

A large trolley of 135 items was also compared. These items consist of the original 39 products, plus 96 more. This analysis excluded Aldi and Lidl however, as they do not sell the full range of items included – such as branded items. 

The cheapest trolley came from Asda, coming in at £332.40. Asda has been the cheapest traditional supermarket since January 2020. The next cheapest was Morrisons, which came in at £2.07 more, or £334.47 for the trolley. Waitrose once again was the most expensive trolley – over £30 more than Asda (£363.99).

Once again, this analysis from Which? shows that considerable savings can be made by consumers, depending on where they tend to shop for food. Whilst more supermarkets are introducing discounts and value brands, more must be done to support consumers with rising food costs. 

Ele Clark, Which? Retail Editor, said: 

“The price of food and drink has continued to soar as people suffer through the worst cost of living crisis in decades. It’s no surprise to see many people turning to discounters like Aldi and Lidl when our research shows they could save up to £17 on a basket of everyday groceries by doing so. 

“Supermarkets aren’t currently doing enough to help shoppers. Which? believes the big retailers have a responsibility to ensure everyone has easy access to basic, affordable food ranges at a store near them, and to provide transparent and comparable pricing so people can easily work out which products offer the best value.”

Agree with this for some things. Shopping across lots of different shops has strengths in lots of areas…. Even M&S has some bargains these days
