The decision follows a 12-month period of research and consultation with stakeholders.
It is hoped the move will allow the series, which includes IFSEC International, FIREX International, Safety & Health Expo and Facilities Show, to grow and attract greater numbers of international attendees.
Simon Parker, managing director of UBM Live London, said it was a "natural progression" for the events.
"We are very excited at the prospect of a move to Excel which will enable us to continue to grow these enormously successful events by taking advantage of both the benefits of a London location and the ability to attract new visitor sectors," he said.
The decision has been backed by members of the industry. Simon Everest, head of the Security Directorate in the UK Trade & Investment Defence & Security Organisation said: "I am delighted to see that UBM Live is relocating to London, taking on board feedback from their customers. A move to London offers UK businesses an exciting global stage to develop export opportunities."
The Protection & Management Series will take place at Excel London from 17 -19 June 2014.
