In 2002, Clarke moved back to the British National League by joining the Guildford Flames, scoring forty-nine points in forty-one appearances.

Clarke was signed by the Nottingham Panthers where he became a fan favourite taking thirty points from forty four games in his first season and sixty-one from sixty in his second.

Clarke was re-signed by Nottingham for the 2009/10 season where he helped the Panthers win the Challenge cup and qualify for the final four of the Elite league playoffs.

After the 2010 playoffs, Clarke left with the Team GB squad for the Division 1 World championships in Slovenia where they would end up finishing in fourth position.

The GB team fell foul of the volcanic ash cloud that cancelled flights throughout Europe at this time and had to endure a 27-hour bus journey from England to Slovenia.
