Following relegation, Billings remained with the Essex club and during 2010–11 had the best try-scoring form of his career with 15 tries in 29 appearances for a Southend side that finished 4th in a competitive National League 2 South that featured teams such as Ealing Trailfinders, Jersey and Richmond. By 2014–15 Billings was captaining a Southend side that only just survived relegation thanks to a losing bonus point in their final game against Redruth, which tied them level with Lydney who went down instead due to having a poorer overall record. The next season Southend were unable to survive as they were relegated in 15th place, some 20 off safety. In the summer of 2016 Billings left to join another Essex club, Rochford Hundred, playing several divisions below Southend in London 2 North East, to take up a position as player-coach.
