The Hammers competed in the National League (the second league tier) from 1984 until 1990. In 1991 Arena Essex won the British League Division Two Championship and were promoted to the British League. They remained in the top flight until the end of the 1995 season, when a promotion change meant the Hammers had to drop to the Conference League for 1996. From 1997 to 2003, Arena Essex competed in the Premier League, before moving up into the Elite League, the top league of British speedway.
