CMA Expands Rules to Aldi and Lidl

What's happened

The CMA has provisionalised rules to stop big grocers from blocking rival stores. Aldi and Lidl are now included in the land-use restrictions, alongside Asda, Co-op, Morrisons, Sainsbury’s, Tesco and Waitrose. Final decision expected in October.

What's behind the headline?

Analysis

• The CMA is widening an existing framework to maintain competitive access for new store openings. This aligns with a trend of scrutinising discount retailers that rapidly expand.
• The provisional nature of the decision invites stakeholder views, suggesting the final shape of the policy could change before October.
• By treating Aldi and Lidl the same as incumbents, the CMA aims to prevent market dominance shortcuts that could squeeze out rivals.

Key implications for readers: more supermarket choice and potentially stable prices as the discount chains grow. Watch for final CMA ruling in October and how retailers respond with expansion plans.

How we got here

The Competition and Markets Authority has proposed applying land-use restrictions to Aldi and Lidl after their store expansion. Current rules, introduced in 2010, prevent large grocers from blocking rivals through covenants and exclusivity. The CMA notes Aldi and Lidl have grown, with market shares around 10.8% and 8.8% respectively, prompting a broader application of the rules.
