Aldi has regained its position 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 with its loyalty program, Lidl Plus, which averaged £128.30.
Although Lidl held the top spot in July, it now ranks second for affordability. The comparison included a mix of branded and own-brand items like Birds Eye Peas, Hovis bread, milk, and butter.
Tesco Clubcard members spent an average of £142.36, while non-members paid £145.01 for the same basket. Sainsbury’s Nectar cardholders paid £144.75 on average, compared to £149.02 for non-cardholders.
For a larger selection of 190 items, Asda remains the most budget-friendly supermarket this month. 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 smaller and larger baskets, costing £172.61 for the former – £44.69 more than Aldi – and £548.14 for the latter.
Reena Sewraz, Which? Retail Editor, commented: “Aldi is once again the UK’s most economical supermarket in August, offering excellent value without requiring membership fees. Asda stands out as the cheapest non-discounter supermarket for larger shopping trips, outperforming Tesco, Sainsbury’s, and Morrisons. With increasing expenses as the seasons change, households can find savings by selecting one supermarket over another, potentially saving up to 35%.”
