Aldi has regained its position as the most economical supermarket in the UK, surpassing Lidl in recent comparative pricing. According to the latest supermarket price check conducted by Which?, a basket of 75 items at Aldi in August 2025 averaged £127.92, making it 38p cheaper than Lidl, which totaled £128.30 on average with its Lidl Plus loyalty program.
In July, Lidl held the title of the cheapest supermarket but has now slipped to second place. The comparison list included a variety of products, both branded and own-label, such as Birds Eye Peas, Hovis bread, milk, and butter.
Tesco Clubcard holders spent an average of £142.36, while non-Clubcard customers paid £145.01 for their shopping. Sainsbury’s Nectar card users had an average bill of £144.75, compared to £149.02 for those without a Nectar card.
Asda maintained its position as the most budget-friendly supermarket this month for a larger list of 190 items. Aldi and Lidl were excluded from this comparison due to their smaller product ranges. The average cost of a bigger shopping trip at Asda was £474.86, undercutting Tesco with a Clubcard by £11.03 (£485.89).
Waitrose emerged as the priciest option, with average costs of £172.61 for the smaller shop and £548.14 for the larger one.
Reena Sewraz, Retail Editor at Which?, commented: “Aldi has reclaimed its status as the UK’s most affordable supermarket in August, providing excellent value without requiring membership fees. Asda remains the cheapest non-discounter supermarket for larger grocery hauls, outperforming Tesco, Sainsbury’s, and Morrisons. With expenses on the rise as the days get shorter and cooler, many households will be concerned about their budgets. However, significant savings can be achieved by simply choosing one supermarket over another, potentially saving up to 35%.”
Opting for different supermarkets based on price variations can lead to substantial savings, especially in times of financial concern.
