LifestyleFood & DrinkSupermarketsResearch names the cheapest UK supermarket for branded products such as Heinz beans and Nescafé coffee07:14, 08 Jul 2026When it comes to doing the weekly shop, some people swear by branded products over supermarket own-label alternatives. With food bills continuing to climb, Brits are constantly hunting for fresh ways to trim a few quid off their spending.‌Fortunately, new research from Which? has revealed which supermarket offers the best value for branded goods. The consumer watchdog discovered that shoppers can end up paying more than double for identical products, depending on where and when they shop and whether they flash their loyalty card.‌Which? found that certain everyday household staples were hit by price differences of more than 100% across UK supermarkets in June.‌The consumer group examined 232 popular branded items, including Heinz beans, Nescafé coffee and Mr Kipling cakes, and found that Asda came out cheapest.This marks the fifth consecutive month that Asda has held the top spot. The basket of groceries averaged £783.31 throughout June.‌While Aldi and Lidl have been crowned the cheapest supermarkets overall by Which? in its monthly comparisons, neither chain features in the branded research due to not carrying a wide range of household name products.Which? discovered that Tesco shoppers using a Clubcard paid £804.68, Sainsbury's customers with a Nectar card forked out £812.61, and Morrisons More card holders spent £814.92.However, shoppers without loyalty cards faced significantly steeper bills for their groceries. Tesco shoppers would need to spend £895.03 on the basket of goods, while Sainsbury's customers would part with £903.40 — both considerably higher than Waitrose at £871.69 and Ocado at £844.22.‌Of the products with the greatest price disparities, half were at their cheapest when purchased using a loyalty card.Listerine Total Care Clean Mint Antibacterial Mouthwash (500ml) was found to carry the biggest price difference, averaging £2.80 at Tesco with a Clubcard but jumping to £6.00 without one — a whopping difference of 114%.Article continues belowNatalie Hitchins, head of home products and services at Which?, said: "With many households still facing intense financial strain and bracing for predicted price hikes in the coming months, every penny counts."Our research has previously found that 'discount loops' on certain branded items are now so frequent that shoppers should never actually pay full price for them."To avoid being caught out, consumers need to be aware of big price fluctuations, compare value across different products, and check rival retailers to ensure they are getting a genuine deal."Choose Daily Mirror as a 'Preferred Source' on Google News for quick access to the news you value.‌AsdaLidlNescafeTescoSainsbury'sSupermarkets
