The Tigers only fielded one team but moved up into the Eastern Division of the Rugby League Conference in 2005.
In 2006 the Tigers first team were crowned champions of the Eastern Division after defeating St Ives Roosters in the regional grand final.
Tigers went on to become finalists in the league play off final in 2017 and 2018, retaining the East RL Cup again in 2017, and again in 2018 for an unprecedented fourth time in a row.
They have set up 3 other "Satellite Clubs", Ampthill Hornets, Dunstable Dragons and Luton Vipers with the aim of generating local junior activity and competition in the summer months.
These clubs have U14 and U16 age ranges and provide the start of the player pathway to the Tigers senior squad.
