It’s been said numerous times that London is the financial capital of the world, so it’s no wonder that some of the biggest companies in the world have headquarters here. The top 25 companies based in London employ thousands of people in the city, and millions throughout the world. These companies do business in the banking sectors, securities, insurance, oil and gas, etc. While some of the companies on the list are practically household names, there are a few names that are mostly known in certain circles. For example, everyone has heard of British Petroleum (BP), GlaxoSmithKline, but you probably never heard of Unilever, despite it being a major player. Companies such as Google, Microsoft also have large and important offices in the city of London. Pretty much every major public company has to be present in this city, otherwise their market share is bound to decline. These companies are worth tens of billions of dollars, and they make profits that are unimaginable by most of us. The banks have come under fire ever since the 2008 crash, and oil companies like BP are often criticized for their negative impact on the environment, but the fact is these companies are here to stay, for now anyway. Without further ado, here are our picks of the top 25 London based companies.
