Largest companies based in the UK by revenue 2024

Shell had the highest annual revenue of all companies based in the United Kingdom in 2024, at approximately 289.7 billion U.S. dollars. BP had the second-highest annual revenue at 202.8 billion dollars, followed by HSBC Holdings, which had a revenue of 144.9 billion U.S. dollars. In terms of global employee numbers, however, Compass Group had the highest number among UK-based businesses, at approximately half a million in 2024, followed by Tesco at 345,000 and HSBC at almost 214,000. 

Big Oil, a banking giant, and Britain's top supermarket chain

The two companies listed as having the most revenue in the UK this year also two of the biggest oil and gas companies in the world, alongside Chevron, Eni, ExxonMobil, and TotalEnergies. After a huge surge in energy prices in 2022, these companies saw their profits recede slightly in 2023, but clearly remain in strong financial positions. HSBC Holdings, meanwhile, was the largest bank in Europe in terms of market capitalization, and was estimated to have the third-highest number of UK-based customers in 2023. The company with the fourth-highest revenue in this year, Tesco has by some distance the largest grocery-market share in Great Britain, a position it has maintained despite growing competition from discounters like Lidl and Aldi. 

UK economy health check

In the first two quarters of 2024, the UK economy grew by 0.7 percent, and 0.6 percent, emerging from a brief recession at the end of 2023. Consumer Price inflation, which reached a peak of 11.1 percent in October 2022, fell below two percent in September 2024, for the first time since April 2021, potentially leading to further interest rate cuts. Despite these generally positive signs, business confidence in the UK in September 2024 was lower than at any point since early 2021. Company insolvencies in England and Wales have also reached levels not seen since the global financial crisis in the late 2000s. This generally mixed picture will be influenced by the next government budget set for the end of October 2024, which may see certain taxes increase due to the UK's tricky fiscal situation.
