The Club entered the Welsh League for the first time in season 2005/6 and a very successful year ended with the Third Division Championship being won after close rivals West End had been deducted three points. Season 2006/7 turned out to be even more memorable as promotion was gained to the top division of the Welsh League with a second placed finish behind champions Garw. In addition the Youth side won the MacWhirter Cup defeating Pontardawe Town 5-2 in the final as well as finishing runners up in their division. In the 2007/8 season, the clubs first ever in Division One began with an incredible 5 straight wins and although the small squad could not sustain this long term, a creditable ninth place was achieved. The club also embarked on a new venture, taking over and forming the new RCT UEFA Academy programme. This has gone from strength to strength over the past few seasons and the club now runs age groups from 7 through to 19 at elite level.
A major change also took place on the Management Committee in 2008, with former England Manager Terry Venables agreeing to become chairman of the club. Terry was already Patron of the highly successful Cambrian Village Trust and has close links with Clydach Vale, where his mother was born. Last season after challenging for the title over the last few seasons Cambrian & Clydach became champions of the Welsh League for the first time in its history
