Aldi has secured the title of the UK's cheapest supermarket for June 2026, marking its sixth consecutive month at the top, according to consumer group Which?. The discounter was only outperformed by Lidl in July and October of the previous year but has since regained its crown.
Price Comparison Details
Which?'s monthly analysis found that a basket of 95 items at Aldi cost £163.34 in June, making it the most affordable option. This was £1.45 cheaper than Lidl, even when using Lidl's Plus loyalty discount. Without the loyalty app, Lidl's basket came in at £164.92.
Asda ranked fourth, with the same items costing £190.39. Sainsbury's with Nectar followed at £193.30, Tesco with Clubcard at £194.67, and Morrisons with More at £198.41. Waitrose remained the most expensive supermarket, with the basket averaging £229.88, a difference of £66.54 (nearly 41%) compared to Aldi.
Industry Response
Julie Ashfield, chief commercial officer at Aldi UK, said: “Being named Which?’s Cheapest Supermarket for the entire first half of this year is fantastic recognition of our unwavering commitment to offering customers the very best value.”
Fraser McKevitt, head of retail and consumer insight at Worldpanel, noted: “Nearly a third of all grocery spending is now on promotion, and that upward streak shows no sign of breaking. Combined with strong online growth, it points to shoppers who know what they want and are increasingly confident about where and how to find the best deal. In short, retailers are having to compete hard for that summer shop.”
Market Outlook
The announcement comes as the boss of Sainsbury's warned of inflationary “pressure” still to come through the supply chain, amid uncertainty over how the Middle East conflict will affect shoppers. The supermarket giant described recent trading as “encouraging” but noted some caution among consumers.
