This order is designed to prevent large grocery retailers from using land agreements to block competitors from opening nearby stores, often through restrictive covenants or exclusivity terms. "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. The CMA’s review found that Aldi, Lidl GB, and Lidl NI now meet the criteria of ‘Large Grocery Retailers’ (LGRs) due to their store footprint, nationwide presence, procurement model, and the breadth of their grocery range. All three now operate large grocery stores, each with more than 1,000 square metres of shop floor space, and offer a full range of products, though with less category choice than some competitors. With the UK grocery market estimated to be worth £215 billion, Aldi and Lidl are now ranked among the top five retailers by market share.
