Aldi has regained its position as the most economical supermarket in Britain, according to recent research by consumer group Which?. The study compared the prices of a set list of 70 items at various supermarkets. Last month, the average cost of these items at Aldi was £121.22, narrowly beating out Lidl, which had an average price of £122.35 for the same goods. Tesco was slightly pricier, but Clubcard members were able to save an average of £2.55, with a total cost of £133.65 compared to £136.20 without the discount.

In contrast, Waitrose emerged as the most expensive option, with an average total of £166.79 for the same items. Opting to purchase all groceries from either Aldi or Waitrose would result in savings of over £45.

Which? conducts this comparison monthly, analyzing the pricing strategies of eight different supermarket chains across a range of products, including both own-label items and popular brands like Birds Eye and Hovis.

A larger list of 183 groceries was also compared, excluding Aldi and Lidl due to their limited range of branded products. Asda emerged as the most cost-effective choice for this extended shopping list, with an average cost of £455.52 last month. The supermarket has committed to reducing prices to compete with rivals, including discount retailers.

For the larger shopping list, Waitrose was the most expensive option at £522.91, significantly higher than Asda’s total. Which? recommends Asda for those seeking a wider selection of branded goods at competitive prices.

Reena Sewraz, Which? retail editor, emphasized the benefits of shopping at Aldi and Lidl for cost-conscious consumers, while noting Asda’s affordability and range of products. With the holiday season approaching, household budgets may be a concern, but strategic shopping choices could result in significant savings.
