Survey time period: 12 weeks ending January 4, 2015 to 12 weeks ending July 13, 2025
In the 12 weeks ending on July 13, 2025, Tesco's sales grew by 7.1 percent, the highest figure since December 2023. Tesco experienced peak sales growth throughout the pandemic. In the 12 weeks ending in July 2020, sales grew by just over percent when compared to the same period in the previous year. Throughout 2020 and 2021, this growth dipped, even reaching a loss of percent in November 2021. During the second half of 2022 and 2023, growth picked up again. This coincided with periods of high inflation felt around the world.
A market leader under attack
Tesco’s is the biggest of the so-called big four, a group of supermarkets including Sainsbury’s, Asda, and Morrisons that dominate the UK market. However, in September 2022, Aldi overtook Morrisons as the fourth largest supermarket in the UK; Tesco's position as market leader is currently under attack. In April of 2019, a merger, which would have cost the company the number one spot on the British grocery market, of Sainsbury’s and Asda failed.
Tesco in numbers
Tesco operates just over stores in the UK. The company made a revenue of roughly billion British pounds in the UK and Republic of Ireland in 2023/24, approximately times the revenue that the company makes in Central Europe.
