May 2023: UK’s most cost-effective supermarket revealed.

Every month, we bring you the UK’s most cost-effective supermarket, in response to consumer website Which?.  

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

This month we’re back, bringing you the most affordable place to purchase groceries in May 2023. 

And the winner is… 

Aldi! Aldi tops the most affordable supermarket list for the twelfth month in a row.

Every month, the evaluation by Which? compares the costs of a basket of 39 popular grocery items at eight of the UK’s biggest supermarkets. The patron champion found that in April, shoppers could save a tidy £17 on a basket of things from Aldi, in comparison with the costliest store.  

The outcomes 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 nonetheless, with results for April showing only a 65p difference. 

Waitrose got here in as the costliest supermarket, coming in at a mean of £87.91 over the month – a staggering difference of £18.31 more. 

A big trolley of 135 items was also compared. These things consist of the unique 39 products, plus 96 more. This evaluation excluded Aldi and Lidl nonetheless, as they don’t sell the total range of things included – resembling branded items. 

The most affordable trolley got here from Asda, coming in at £332.40. Asda has been the most affordable traditional supermarket since January 2020. The following most cost-effective was Morrisons, which got here in at £2.07 more, or £334.47 for the trolley. Waitrose once more was the costliest trolley – over £30 greater than Asda (£363.99).

Once more, this evaluation from Which? shows that considerable savings could be made by consumers, depending on where they have a tendency to buy food. Whilst more supermarkets are introducing discounts and value brands, more should be done to support consumers with rising food costs. 

Ele Clark, Which? Retail Editor, said: 

“The value of foods and drinks has continued to soar as people suffer through the worst cost of living crisis in a long time. It’s no surprise to see many individuals turning to discounters like Aldi and Lidl when our research shows they might save as much as £17 on a basket of on a regular basis groceries by doing so. 

“Supermarkets aren’t currently doing enough to assist shoppers. Which? believes the large retailers have a responsibility to make sure everyone has quick access to basic, reasonably priced food ranges at a store near them, and to offer transparent and comparable pricing so people can easily work out which products offer the very best value.”
