In their inaurgural year, the Tigers finished third in the Welsh division and reached the final of the RLC Plate competition where they lost to East Lancashire Lions. They also reached the National Conference Plate Final, losing to East Hull and, in the process, becoming one of the last teams to play on Warrington's Wilderspool ground before the Super League club moved out.
2004 saw the Tigers consolidate their position within the Welsh division and reach the semi-final of the Harry Jepson Trophy.
The Tigers got off to a slow start in 2005, but as new young players grew in confidence the team's results improved. The second half of the season saw the Tigers become the first Welsh side to beat Bridgend Blue Bulls since the league had been formed, and continuing success saw them go on to beat Aberavon Fighting Irish to earn them a place in the Welsh Grand Final for the first time. Against the holders Bridgend, The Tigers got off to a good start and lead for much of the first half, but Bridgend dug deep and battled back to retain their title.
In 2012, the club decided that the infrastructure at the club was unsustainable and decided to not to enter the South Wales Premier to rebuild and ensure long term sustainability. The club got a new board and they moved ground from Pontypool United RFC to Cwmbran RFC's Kings Head ground.
Tigers returned to the South Wales Premier for the 2013 season.
