Aldi has been named as the cheapest UK supermarket in August, beating Lidl, Sainsbury’s and Tesco, even when factoring in loyalty discounts.

According to the latest data from Which?, which compared the prices of 62 popular grocery items including Heinz baked beans, milk and cheese, Aldi was the least expensive at £110.58.

Aldi UK managing director of buying Julie Ashfield said: “We’ve always promised our customers that we will never be beaten on price, and when looking at the Which? analysis, the results speak for themselves.

“Our ongoing commitment to providing shoppers with the very best, for less clearly shines through when customers see how much money they can save simply by switching to Aldi.”
