Aldi has once again emerged as the most affordable supermarket in the latest monthly price comparison conducted by Which?. In May, a shopping list of 95 items averaged at £168.30 at Aldi, narrowly edging out Lidl by £2.28, where the same list cost £170.58 with Lidl Plus or £170.66 without it.
Asda secured the fourth spot at £192.58, followed by Tesco at £196.88 for Clubcard holders. The average bill at Morrisons tallied to £197.50, while Sainsbury’s, with Nectar, amounted to £198.79. Without a Clubcard, Tesco priced at £202.27, and Sainsbury’s without a Nectar stood at £206.18. Waitrose retained its position as the priciest supermarket, totaling £235.49, which is 40% higher than Aldi.
Despite being the costliest, Waitrose recently announced a £20 million price reduction initiative on everyday essentials. Ocado ranked as the second most expensive at £217.86.
Which? regularly compares prices of various grocery items across eight major supermarkets throughout the year using an independent price comparison platform. The analysis involves assessing the average prices of individual items and summing them up to determine each store’s average cost.
The list of items includes both branded and own-label products such as Cathedral City, Birds Eye, and Hovis. The study incorporates special offer prices and loyalty discounts where relevant but excludes multi-buy promotions. Which? refrains from sharing the full product list with retailers.
This latest survey highlights the potential for shoppers to save on their shopping bills based on where they choose to shop. Reena Sewraz, Which? Retail Editor, emphasized the significance of consistent low prices without complex loyalty schemes. She noted that Aldi and Lidl excel in providing everyday value, attracting customers as shopping habits evolve.
Sewraz pointed out that opting for the wrong supermarket could lead to paying significantly more for essential items, underscoring the substantial savings achievable by switching where one does their weekly shopping.
