BECA members will be briefed on the details this month ahead of its AGM on 30 March.
AEC chairman Steve Barratt confirmed initial discussions had taken place but declined to comment further.
Creating an association that represents contractors and suppliers has been discussed for a number of years.

The AEC's umbrella body, the Event Industry Alliance, aims to establish a single event industry trade body.
