The largest companies of the United Kingdom greatly impact the British and world economy. The UK’s top 30 publicly traded companies, major components of the FTSE index, are presented here together with their activities, logos, sectors and useful links.
In the United Kingdom, companies become publicly listed companies – PLC – to get listed on the London Stock Exchange.

The FTSE 100 Index
To ease the understanding of the evolution of the British stock market and the broader economy, the stocks of the 100 largest companies by market capitalization are aggregated in the FTSE 100. Meaning “Financial Time Stock Exchange 100” Index, and often more simply referred to as FTSE, it is widely recognized as the benchmark index of the British stock market.
Based upon the stocks of 100 companies, the FTSE is a capitalization-weighted index, where larger companies are weighted more heavily in the index, and it represents around 70% of the total market capitalization of the companies listed on the London Stock Exchange.
