IMPA London 2012 will take place in September and will welcome 1,500 international visitors and more than 90 exhibitors. The gathering has previously been held at Kensington Town Hall.
IMPA chief operating officer Steven Alexander said: "IMPA London had outgrown its original home. The QEIICC provides a flexible space, so we can grow our event and double visitor and exhibitor numbers."
The organisation has already sold 90% of exhibition space for the 2012 event. David Greenwood, sales manager at First Choice Marine Supply, said: "We are excited about the move. Our company will be investing in a larger booth and in the success of the show."
