Annual revenue of security companies in the UK 2021-2024
In 2024, Mitie Total Security Management topped the list of the leading companies in the regulated security sector in the United Kingdom. With a revenue of approximately *** billion British pounds, the company had a significant lead on other competitors, and increased their estimated annual turnover by more than ** million British pounds between 2021 and 2024.
The UK security industry
In 2024, the region in the United Kingdom with the most enterprises in the security and investigation activities sector was London. This may have been deemed as somewhat necessary as recorded violent crime offences in the English capital city grew as COVID-19 measures were lifted, with the cost of living crisis and some of the most expensive rental costs per square meter in Europe also having increased in stature correspondingly. This was potentially good news for those involved in the business of security services, as the number of people employed in elementary security occupations grew significantly between 2021 and 2024.
The big global players
Securitas had the second-highest revenue of security companies in the United States in 2023 and the fourth-highest revenue in the United Kingdom in the same year. The size of the global security services market was recently valued at approximately *** billion U.S. dollars. To give some context to the immense monetary value of this service, the global consulting market was valued at roughly the same amount in the corresponding year.
