In the United Kingdom, Aldi has maintained its position as the cheapest supermarket for eight consecutive months. According to a Which? monthly comparison of 92 branded and own-label products, Aldi’s basket averaged £159.36, narrowly surpassing Lidl, which averaged £161.10.

To compete with these discounters, traditional retailers are increasingly relying on loyalty schemes. For instance, Sainsbury’s reduced its basket cost from £195.33 to £185.55 when Nectar loyalty pricing was applied, while Tesco’s Clubcard has also provided notable discounts.

The rivalry between Aldi and Lidl is also extending into physical expansion, with both retailers submitting planning applications for new stores in the Norfolk market town of Holt. This has prompted local debate over whether budget brands are appropriate for the historic area, despite arguments that the town requires more affordable grocery options.
