Cheapest supermarkets 2025
Which is the UK's cheapest supermarket in 2025?
Every month, we compare thousands of prices at eight of the UK's major supermarkets – Aldi, Asda, Lidl, Morrisons, Ocado, Sainsbury’s, Tesco and Waitrose – to reveal the cheapest supermarket to buy your food, drink and household essentials.
Aldi has taken the crown in recent months, closely followed by Lidl – but how do big chains such as Tesco and Sainsbury's compare, and does being a member of a loyalty scheme make a significant difference to the cost of a basket of groceries?
Read on to find out the latest results of our supermarket price comparison.
May 2025
Aldi was the cheapest supermarket in May, charging £135.48 on average for our shopping list of 82 branded and own-label groceries.

Asda, which doesn't offer loyalty discounts in the same way, was the cheapest of the traditional supermarkets – our shopping cost £149.94.
Waitrose was the most expensive supermarket at £184.03 – 36% more than Aldi.

How we work out which is the cheapest supermarket
We track the prices of up to 200 branded and own-label products every day over the course of a month to work out the average cost per item. We then add up those averages to get a total for each retailer. We include special offers and, since June 2024, loyalty prices where applicable, but not multibuys.
We can’t include the value of points, personalised discounts or other rewards as these vary from customer to customer.
Products on our list include everything from Heinz baked beans and Mr Kipling cakes to own-label milk, bread and cheese.
Our data is supplied by an independent price comparison company. For stores that don't have online prices, we send fieldworkers out to gather prices.
The master list of 200 products is currently updated annually but otherwise remains constant. However, the specific products chosen from the master list vary from month to month depending on availability. This means the totals aren't comparable between months or years.
