Aldi has been confirmed as the UK's cheapest supermarket for July 2026 by consumer champion Which?, marking its ninth consecutive month at the top. To celebrate, the discount retailer is offering shoppers the chance to win £100 Aldi vouchers, with 10 winners selected.
Which? Analysis Confirms Aldi's Price Leadership
The latest independent analysis from Which? compared a basket of 93 popular grocery items across major UK supermarkets. Aldi's basket cost just £158.05, undercutting competitors by significant margins. Shoppers could save up to £30.40 compared to Tesco, £29.81 compared to Sainsbury's (even when loyalty discounts are applied), and a substantial £68.90 compared to Waitrose.
This achievement extends Aldi's winning streak throughout 2026, with a 100% success rate so far this year. The nine-month run dates back to November 2025, and Aldi was also named Which?'s Cheapest Supermarket of the Year for 2025, alongside its recent recognition as 'Best Value Brand of the Year'.
Win £100 Aldi Vouchers
In partnership with the retailer, we are giving away £100 Aldi vouchers to 10 lucky winners. These vouchers can be redeemed across Aldi's entire product range, including fresh fruit and vegetables, summer BBQ essentials, cupboard staples, household necessities, and health and beauty products.
Julie Ashfield, Chief Commercial Officer at Aldi UK, commented: "We are delighted to be crowned the UK's cheapest supermarket for the ninth month in a row. The school summer holidays, while lots of fun, can also be a time when many households feel the financial pinch. Our customers can shop with confidence throughout the summer, knowing they're getting award-winning quality without the hefty price tag, and putting those savings towards more of the moments that matter."
