5/27/2026, 11:40:36 PM
Milestone Achievement
In the 12-week period to 17 May 2026, Lidl’s sales rose 8.8 % YoY, raising its market share to 8.6 % (Worldpanel). The gain moved Lidl ahead of Morrisons, whose share fell to 8.3 % and whose sales grew only 1.3 %. Lidl now ranks fifth behind Tesco (28.2 %), Sainsbury’s (15.2 %), Asda (11.5 %) and Aldi (10.8 %).
Growth Context
Since its UK launch in 1994, Lidl has grown to 1,000 stores and 35,000 staff, expanding its share from 1.4 % in 1999 to 8.6 % today. It has been the fastest-growing bricks-and-mortar retailer for 35 months, earning £661 million in switching gains as over three-in-five households now shop there. Ocado posted the strongest growth among all grocers, with sales up 10.2 % and a 2.1 % share.
Official Responses
Lidl CEO Ryan McDonnell said the milestone shows sustained momentum and a focus on reliable value. A Morrisons spokesperson said Worldpanel’s figures omit convenience-store sales, a sizable part of Morrisons’ turnover, and claimed its share has been stable since early 2025 while serving over 10 million customers weekly. Worldpanel head Fraser McKevitt noted grocery-price inflation slowed to 3.1 % YoY, calling it welcome news for shoppers.
Criticism and Methodological Dispute
Morrisons’ objection highlights a broader debate over market-share calculations that exclude convenience formats, potentially understating its footprint. Lidl’s loyalty programme, Lidl Plus, has also faced criticism after the Points Plus scheme was seen as less generous than its predecessor, raising concerns about future growth.
Impact on the Grocery Sector
The reshuffle intensifies price competition; 30.3 % of May sales involved promotions, up from 28.4 % a year earlier, while full-price spending was flat. Slower inflation and pending tariff suspensions may further compress margins and boost discount retailers. Traditional chains are responding with stronger loyalty schemes and price-matching ranges.
