The market share of grocery stores in United Kingdom (UK) is shown in this data on a monthly basis from January 2017 to June 2022. Ocado, Symbols & Independents, The Co-op, Iceland, and other retailers were able to grow their market shares the fastest during the coronavirus outbreak. From March 2020 to May 2020, Asda was particularly heavily hit and saw a decline in its market share of over 1%.
Tesco and Sainsbury’s held 42.2 percent of the market collectively as of June 2022, representing the company with the biggest share during the time under examination. The “big four” supermarkets—Tesco, Sainsbury’s, Asda, and Morrisons—dominated the grocery retail sector before discounters became well-known.

However, consumer behavior has changed in favor of less expensive options like Aldi and Lidl as a result of the post-Brexit uncertainties and rising prices. As a result of the ensuing “price wars,” supermarkets have lowered their pricing. Importantly, this has exacerbated market volatility for groceries, and as of January 2017, Aldi passed the Co-operative to take the fifth-largest spot among British supermarkets. After a period of fierce battle, Lidl passed Waitrose and then, by the end of 2020, overtook Co-op for the first time.
