Announcing the fixture, the England and Wales Cricket Board's managing director of cricket, Hugh Morris, said: "Our three-day match against Warwickshire at Edgbaston in 2009 provided excellent preparation for the Test squad ahead of the Ashes Test series and we are very grateful to Essex for providing us with a similar warm-up fixture next summer during a period when there is a break in the LV= County Championship schedule."
The ECB have also confirmed the dates of next season's domestic finals.
Friends Life t20 Finals Day will be held at Edgbaston on August 17, with the Clydesdale Bank 40 showpiece once again at Lord's on September 21.
