Aldi reclaims its title as the most budget-friendly supermarket in the UK, surpassing Lidl this month. According to the latest supermarket price analysis by Which?, a basket of 75 items averaged £127.92 at Aldi in August 2025. This cost was 38p lower than the same basket at Lidl, which totaled £128.30 on average with the Lidl Plus loyalty scheme.
Despite Lidl holding the top spot in July, it now ranks second in affordability. The comparison included a mix of branded and own-brand products like Birds Eye Peas, Hovis bread, milk, and butter.
Tesco Clubcard holders spent an average of £142.36, while non-members paid £145.01 for the same items at Tesco. Sainsbury’s Nectar card users paid £144.75 on average, compared to £149.02 for non-cardholders.
For a more extensive list of 190 items, Asda remains the most economical choice this month. Excluding Aldi and Lidl due to their smaller product ranges, Asda’s larger basket averaged £474.86, undercutting Tesco with a Clubcard by £11.03 (£485.89).
Waitrose emerged as the priciest option for both small and large shopping lists, with costs averaging £172.61 and £548.14, respectively.
Reena Sewraz, Which? Retail Editor, noted, “Aldi is back as the UK’s most cost-effective supermarket for August, offering great value without membership fees. Asda stands out as the cheapest non-discount supermarket for larger grocery hauls, outperforming Tesco, Sainsbury’s, and Morrisons.”
With winter approaching and expenses likely to rise, households can benefit from cost savings by exploring different supermarket options. Simply opting for one store over another could result in savings of up to 35%.
