Which? has revealed how supermarket grocery prices compared from shop to shop last month. Every month, the consumer champion compares thousands of prices at the UK’s eight biggest supermarkets – Aldi, Asda, Lidl, Morrisons, Ocado, Sainsbury’s, Tesco and Waitrose – to reveal the cheapest place to buy your groceries and household essentials.

Which? compares a small basket of items at shops including Aldi and Lidl with retail giants including Tesco and Asda to see where you money will go the furthest. The comparison includes 37 everyday items and groceries each month.

This month, Aldi was the cheapest supermarket in August overall, with the shop costing £65.21, pipping its discounter rival Lidl to the post by £1.32. The same basket of items at Waitrose would have set you back an average of £79.51, that’s 22% pricier on average than Aldi.
