Overview of the Price Comparison
In January 2026, Tesco has been identified as the UK's cheapest supermarket for a large weekly shop, surpassing Asda for the first time in over a year. According to consumer group Which?, Tesco Clubcard holders could purchase a basket of 228 items for £588.96, making it £1.45 cheaper than Asda's price of £590.41. This shift marks a significant change in the competitive landscape of UK supermarkets, where Asda had previously held the top position throughout 2025.
Key Findings from the Analysis
The analysis conducted by Which? involved comparing prices across eight major supermarkets, including Asda, Tesco, Sainsbury’s, and Morrisons, while excluding discount retailers Aldi and Lidl due to their limited product ranges. The findings revealed that Sainsbury’s and Morrisons followed Asda in the rankings, with average prices of £603.55 and £612.88, respectively. Waitrose was noted as the most expensive supermarket, with a total cost of £679.20 for the same basket.
For a smaller shopping list of 89 items, Aldi emerged as the cheapest option at £164.74, followed closely by Lidl at £166.33 for members of its Lidl Plus loyalty scheme. Tesco, with a Clubcard, was the next cheapest at £182.92, while Asda's price for the same smaller basket was £183.04.
Implications of Loyalty Pricing
The analysis highlighted the growing impact of loyalty pricing on grocery bills. Tesco's lowest prices are available only to Clubcard holders, which raises concerns about accessibility for certain groups, including under-18s. Without a Clubcard, the cost at Tesco would rise to £641.09, significantly higher than Asda's prices, which are available to all customers.
Reena Sewraz, retail editor at Which?, emphasized the importance of shopping around, stating, “Choosing one supermarket over another could save shoppers hundreds of pounds over the course of a year.” This sentiment reflects the ongoing price competition among supermarkets, particularly between discount retailers like Aldi and Lidl.
Official Statements & Responses
In response to the findings, an Asda spokesperson defended the supermarket's pricing strategy, asserting that Asda was the lowest-priced supermarket every month in 2025 on the Which? big trolley comparison. They noted that Asda's prices are accessible to all customers without the need for a loyalty card.
Conversely, Tesco highlighted its broader value offerings, including its Aldi Price Match range and Everyday Low Prices, to justify its competitive position in the market.
Criticism & Opposition
Despite the positive reception of Tesco's pricing strategy, critics have pointed out that the reliance on loyalty schemes may disadvantage certain consumers. Sewraz noted, “Tesco must do more to ensure under-18s and other groups who may not be eligible for the Clubcard don’t miss out on those savings.” This criticism underscores the need for supermarkets to consider inclusivity in their pricing models.
Conclusion
The recent price comparison by Which? illustrates a notable shift in the UK supermarket landscape, with Tesco reclaiming the title of the cheapest supermarket for a big shop. Asda's previous dominance has been challenged, prompting discussions about the implications of loyalty pricing and the accessibility of savings for all consumers. As the competition continues, shoppers are encouraged to evaluate their options to maximize savings on their grocery bills.
