The UK's Competition and Markets Authority (CMA) has provisionally proposed that discount supermarket chains Aldi and Lidl should be subject to the same land agreement restrictions that currently apply to seven major grocery retailers. The move aims to prevent these discounters from using restrictive covenants and exclusivity arrangements to block rival supermarkets from opening stores nearby, thereby safeguarding consumer choice and competitive pricing.
What Are the Land Agreement Rules?
Introduced in 2010, the rules were designed to stop large grocery retailers from using land agreements to hinder competition. These agreements often include restrictive covenants or exclusivity clauses that prevent landowners from leasing or selling property to competing supermarkets. The restrictions currently apply to Asda, Co-op, Marks and Spencer, Morrisons, Sainsbury's, Tesco, and Waitrose.
In its provisional decision, the CMA stated that Aldi, Lidl GB, and Lidl NI should also be brought under these rules. The regulator noted that while these discounters were originally excluded due to their more limited product ranges, their significant expansion in recent years—both in the number of stores and the size of outlets—warrants their inclusion now.
Market Share and Expansion
Aldi is currently the UK's fourth largest grocer, holding a 10.8% market share, while Lidl is the sixth largest with an 8.8% share, according to recent data from Worldpanel. Both retailers have grown rapidly through new store openings and have attracted customers with their competitive discount pricing.
The CMA is now seeking further views from stakeholders before making a final decision. Juliette Enser, executive director of competition enforcement and markets at the CMA, emphasized the importance of ensuring consumers have the best choice and prices: "We want everyone to have the best choice of supermarket and range of prices when buying their groceries. To ensure this happens, we put rules in place to prevent big supermarket chains blocking rival stores from opening nearby – and now we propose applying those rules to Aldi and Lidl too."
Retailers' Responses
Both Aldi and Lidl have responded to the provisional decision. An Aldi spokesman said: "The CMA's provisional decision does not impact our long-term growth plans across the UK. We remain firmly committed to opening hundreds of new stores across the country, bringing Aldi's unbeatable value and award-winning quality to even more customers."
A Lidl spokesman added: "We note the CMA's provisional decision regarding our status under the Controlled Land Order. As a discounter, we have always welcomed and embraced competition within the market and our focus remains on continuing to open new stores and bringing our high-quality, lowest-priced groceries to even more communities. Any outcome will not impact our steadfast momentum and growth."
Impact on Consumers and Competition
If the proposal is finalized, Aldi and Lidl would be prohibited from using land agreements to obstruct rival supermarkets from opening nearby. This could lead to increased competition in areas where these discounters have a strong presence, potentially benefiting consumers through lower prices and greater choice.
The CMA's consultation period allows interested parties to submit their views before the final decision is made. The outcome will be closely watched by the retail sector, as it could reshape the competitive landscape in the UK grocery market.
