Hyde Park has used Showsec for major events before, including the 02 Wireless and Hard Rock Calling series of festivals and one-off concerts such as Party in the Park, Live 8 and Nelson Mandela's 90th Birthday Concert.
Royal Parks manages the venue and has recently extended Live Nation's contract to allow the company to stage further events.
"By maintaining and developing our relationships with suppliers, we are able to ensure the continuity of the professional delivery of the highest standard of events, introducing consistent improvements to services in all areas of the site," said Live Nation festival director John Probyn.
