TOP 30 Companies in UK by Revenue in 2025

The United Kingdom remains home to a diverse and dynamic corporate landscape, with energy majors, global banks, insurers, consumer goods groups, and industrial manufacturers all featuring among its largest businesses. Based on the most recently reported financial results (trailing twelve-month figures, mostly covering fiscal year 2025), this article ranks the UK's 30 largest companies by revenue and gives a short overview of what each one does, how it performed, and where it's headed strategically. Revenue figures are in US dollars unless noted, and reflect the latest results available as of mid-2026 — some fiscal years close at different points, so figures are not all for an identical 12-month window.

1. Shell
   
   Shell, headquartered in London, is a fully integrated energy major spanning oil and gas exploration, production, refining, trading, and an expanding low-carbon business. For fiscal year 2025, Shell reported revenue of roughly $266.9 billion, a decline from 2024 as average oil prices fell, though the company still generated close to $43 billion in operating cash flow. Headcount stood at around 84,000 by year-end 2025, down from 96,000 the year before as Shell trimmed costs and divested several non-core businesses, including its Nigerian onshore operations and Singapore chemicals complex. The company continues to prioritize LNG and upstream oil and gas over renewables, while pursuing structural cost cuts it says are now running ahead of schedule.
