Although it is accepted that Betws RFC was in existence some years before the 1890s, the first hard evidence that the club existed was through an Amman United fixture card dating from 1903 and so this was the date taken as the birth of the club. There is also little known about the club until after the Second World War. The club was certainly up and playing in the late 1940s and officially reformed in 1953. As members of Llanelli & District they soon became successful and a decade later they had added 11 district titles. The 1959/60 season saw the club record a treble when they claimed the League Championship Challenge Shield, Open Cup and Lady Howard Cup and the continued success was evident in 1967/68 when they retained the Open and Lady Howard Cups supposedly from the season before. There was then a barren period until the 1992/93 season, when the club claimed the Doreen Rogers Cup and Section B Championship. During this period the club worked hard on and off the field with the aim of securing WRU status. This was achieved in 1997/98 and they signed off from Llanelli & District Rugby in style by securing Section A titles in 95/96, 96/97 and 97/98. As well as triple League Championship Challenge Shields the club also the Lady Howard Cup in both 95/96 and 97/98 and the Champions Cup in 95/96. The club demonstrated competency fit for the WRU National Leagues with immediate promotion from division 7 in 98/99 and in 2007/08 they secured the Division 5 title. The 1st XV currently play in . The Seconds continued in Llanelli & District, they won the Section B title in 2005/06 and again in 2007/08 emulating the 1sts divisional success, they also secured the only Llanelli & District title that had eluded the 1sts - the Buckley Cup.
