Clarion Events Ltd


The Clarion Events’ portfolio of defence and security events is acknowledged as the world’s leading forums where high level government officials and senior military personnel converge. Leading global equipment and services providers meet to share ideas, discuss industry developments, conduct business, develop partnerships and network for future growth.  Whilst military systems and technology are at the core of the industry and the events, the sector is also diversifying and adapting to meet the changing needs of the world. In addition to the threat of war, national security can be threatened by humanitarian disasters resulting in mass displacement of people or food and water shortages, terrorism or pandemic.



The UK defence industry represents ten per cent of UK high technology manufacturing and is the number one exporter in Europe, second only to the US globally. DSEI, which is based at ExCeL London, is a crucial part of that industry. The industry employs over 300,000 people and generates over £35 billion per year to the UK economy. The industry also works hand-in-hand with the UK Armed Forces from factory to frontline, for example over 6,000 industry personnel are currently working alongside our troops in Afghanistan.



The economic benefits are not  just about the defence industry. The 35,000 exhibitors, visitors and contractors attending DSEI occupy over 100,000 room-nights at London hotels during the week of the event, generating an estimated £23m direct benefit to the London economy in the process, even before taking into account all of their associated expenditure on travel, restaurants and the like across the capital during their stay.



All defence and security exhibitions in the UK including DSEI can serve only the legitimate defence and security industry which is the most tightly regulated industry in the world.  This means exhibitors and visitors must adhere to the highest regulatory scrutiny, complying with UK and international laws, treaties and conventions. DSEI itself works closely with government departments including MOD, Foreign and Commonwealth Office, BIS and Home Office to ensure this strict compliance with all rules, regulations and laws. Furthermore, the UK Government itself is responsible for inviting international delegations.
