The market share of the leading supermarkets in Great Britain (GB) from January 2017 to March 2025 has remained fairly stable. Tesco and Sainsbury's had the largest share over the period under consideration, holding **** percent of the market together as of March 2025.
Prior to the popularity of the discounters, the grocery retail market was dominated by the 'big four' supermarkets: Tesco, Sainsbury's, Asda, and Morrisons. On the back of the post-Brexit uncertainty and growing inflation, consumer behavior has shifted in favor of cheaper alternatives such as Aldi and Lidl. In September 2022, Aldi took over fourth place in the grocery store ranking from Morrisons for the first time. In April 2023, Aldi's market share reached double digits for the first time. In March 2025, this figure stood at ** percent.
Market share data is based on all expenditure through main store tills, excludes petrol and in-store concessions.
