Financial difficulties meant that the Lee Valley Lions stopped playing at the season's end.

In 2005, at the request of the Rink Operators, the Lee Valley Lions were reformed under former player and then Junior Head Coach Eddie Joseph.

In their return season, the Lions struggled, suffered several heavy defeats, and failed to register any points.

Whilst there were significant improvements, the league positions during this period were unchanged with the Lions never finishing higher than seventh (2007/08) under the new coach.

The 2009/10 season brought a period of stagnation and under performance for the Lee Valley Lions, unaltered by two changes in Head Coach (Ian Prince and then David Richards).

The last season of George Alley's tenure as Head Coach (2017/18) coincided with a league restructure which pitted powerful former National Ice Hockey League South 1 teams such as Bracknell Hornets, Chelmsford Chieftains, Oxford City Stars and Solent Devils against the traditionally weaker South 2 sides.

The 2018/19 season started with James Joseph leading the team in his first coaching position whilst retaining his role as the club's longest-serving Defenceman.
