A total of 30 clubs were promoted from Step 5 to Step 4, including 4 from the Isthmian League Second Division. The division was then disbanded, with its remaining clubs distributed across the other Step 5 leagues in the South East. It was planned to reduce the number of divisions at that level from 15 to 12, but there was no consensus on how this should be achieved, so 2006–07 ran with fourteen Step 5 divisions, each with between 18 and 22 clubs.
