Which? cheapest supermarket - January 2023

Taking the crown is Aldi, with the retailer found to be the cheapest retailer overall in January 2023. A shop, on average, cost £82.03 beating rival discounter Lidl by £2.04.

The same shop at Waitrose was £107.71, on average, making it £25.68 pricier than Aldi.

Of the Big Four supermarkets, Tesco was the cheapest at £93.80 meanwhile Asda came in at £95.32, which was fourth cheapest in January. This was closely followed by Sainsbury’s with the shop, on average, costing £95.65.

In their comparison, Which? also looked at the cost of a larger trolley consisting of 144 items – the original 45, plus 99 more.

These items included branded items such as Andrex toilet paper and Cathedral City cheese, and did not include discounter supermarkets Aldi and Lidl as they do not always stock some of these products.

For this, Asda came out on top as the cheapest. It cost £363.29 on average, beating the next cheapest, Sainsbury's (£375.84), by £12.55. Waitrose was an eye-watering £45.43 more expensive than Asda, coming in at £408.72, on average, for the trolley of comparable goods.

This latest analysis from Which? comes in a bid to show shoppers where they can save money and how much, on average, they could be spending when they walk through the doors.

Which? also recently launched its Affordable Food For All campaign, calling on supermarkets to provide the support people around the country desperately need in order to keep food on the table during the ongoing cost of living crisis.

Reena Sewraz, Which? Retail Editor, said: "Nobody wants to pay over the odds for their weekly food shop, especially as the cost of living crisis stretches household budgets for millions of people.

"Our findings show that while prices are going up, some supermarkets are significantly more expensive than others. As well as choosing a supermarket that is cheap overall, other ways to save include swapping from branded to supermarket own-brand products, sticking to a shopping list, and resisting the temptation to pick up special offers you may not need."
