Tesco Overtakes Asda as Cheapest Supermarket
Analysis based on 6 articles · First reported Feb 04, 2026 · Last updated Feb 04, 2026
The retail sector, particularly supermarkets, will see increased competition as Tesco's new position as the cheapest for big shops with a Clubcard could shift consumer spending. Walmart — Asda's continued struggle with sales and its loss of the top spot may put pressure on its market share, while Aldi and Lidl maintain their strong positions in the discount segment.
Tesco has surpassed Walmart — Asda as the UK's cheapest supermarket for a big shop in January, according to a Which? analysis. This marks the first time since December 2024 that Tesco has held this title, primarily due to its Clubcard loyalty scheme, which offers significant discounts. Without a Clubcard, Tesco's prices are considerably higher. Walmart — Asda, which offers its prices to all shoppers, was £1.45 more expensive than Tesco with a Clubcard. For smaller shops, Aldi remained the cheapest, followed closely by Lidl. John Lewis Partnership — Waitrose consistently ranked as the most expensive supermarket for both big and small shopping lists. The report highlights the growing importance of loyalty schemes in supermarket pricing and raises concerns about accessibility for certain groups, such as under-18s, who may not be eligible for these discounts.
