The latest Which? comparison has found the cheapest supermarket for a basket of 81 essential items.
Getting in the weekly groceries has become fairly expensive over the years. Which is exactly why many households often look for ways to save money.
For this reason, Which? runs a monthly price comparison across eight of the biggest supermarkets across the UK, with the latest showing how shoppers can save over £48 in total.
For the fifth month in a row, the consumer watchdog's analysis has found that Aldi is once again the most affordable supermarket, charging just £135.48 for a basket of 82 branded and non-branded essentials.
It means that the budget German discounter has taken the crown for every single month this year, following on from its major win in 2024 where it was found to be the cheapest supermarket for the whole year.
By direct comparison, premium chain Waitrose was once again found to be the most expensive option, with the same basket of items coming in at £184.03 - meaning Aldi shoppers are saving 36 percent and £48.55.
However, it is worth noting that, while Aldi held onto its coveted title as the cheapest supermarket, its fellow budget German rival Lidl was hot on its heels, with just 31p more for Plus members (£135.79) and 34p more for regular shoppers (£135.82.)
Out of the traditional supermarkets, the May 2025 Which? comparison found that Asda was offering the most affordable prices, coming fourth place with its own basket of 82 items costing £149.94.
To emphasise Aldi's savings, it was discovered that loyalty schemes from many major supermarkets were still more expensive, as Tesco Clubcard users were being charged £150.26, while regular customers were being charged £152.35.
Meanwhile, Sainsbury's was charging £151.82 for the same 81 items for Nectar members and £155.59 for those not signed up to its loyalty scheme.

Out of the traditional supermarkets, Morrisons was still more expensive, even with a More Card. Those signed up to its loyalty scheme were charged £155.76, while those without would be charged £156.71.
It is worth mentioning that the Which? analysis also covers a much larger shopping list of 198 items, although Aldi and Lidl are not included because they do not offer the same availability of branded items.
Similar to previous months, Asda once again held onto its crown as the most affordable option for the bigger shop, charging shoppers £485.79. Meanwhile, Waitrose was also the most expensive for this shop, with its total coming in at £559.02.
Julie Ashfield, Chief Commercial Officer at Aldi UK, said: 'Which? analysis demonstrates Aldi's determination to provide its customers with quality, affordable groceries as an essential need for the long term.
'We are proud to retain this position of cheapest supermarket for an incredible nineteenth month, allowing our shoppers to save their money for other life essentials.'
