Aldi has regained its title as the most affordable supermarket in the UK, surpassing Lidl this month. According to the latest supermarket price analysis by Which?, a basket of 75 items cost an average of £127.92 at Aldi in August 2025, making it 38p cheaper than the same basket at Lidl, which totaled £128.30 on average when utilizing its loyalty program, Lidl Plus.
In July, Lidl held the top spot as the cheapest supermarket but has now slipped to second place. The comparison included a variety of branded and own-brand items like Birds Eye Peas, Hovis bread, milk, and butter.
For Tesco Clubcard members, the average cost of the 75-item basket was £142.36, while non-members paid £145.01. Sainsbury’s Nectar cardholders spent an average of £144.75, compared to £149.02 for non-Nectar cardholders.
In a larger comparison of 190 items, Asda maintained its position as the most budget-friendly supermarket. Aldi and Lidl were not part of this comparison due to their smaller product ranges. The larger Asda 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 the smaller basket costing £172.61 – £44.69 more than Aldi – and the larger one totaling £548.14.
Reena Sewraz, Which? Retail Editor, commented, “Aldi is once again the UK’s most cost-effective supermarket in August, offering great value without the need for membership fees. Asda stands out as the cheapest non-discounter for larger grocery hauls, outperforming Tesco, Sainsbury’s, and Morrisons. As household expenses rise during cooler months, savvy shoppers can save up to 35% by choosing one supermarket over another.”
