2010–11 Isthmian League

Maidstone United, Croydon Athletic, and Folkestone Invicta were relegated while Aveley were reprieved due to Rushden & Diamonds and Ilkeston Town folding in the Football Conference.

At a meeting on 20 February this proposal was rejected and the club was expelled from the League.

Waltham Forest were reprieved due to clubs folding higher up the pyramid, so no teams were relegated from the division this season.

The draw was not enough for Chatham Town to escape the relegation zone although they were later reprieved due to clubs folding higher up the pyramid.

So, Horsham YMCA were the only club relegated from the Isthmian League this season.
