Briton Ferry being the older was formed in 1925/26 and became members of the Welsh League in the early 1930's.
The team was re-named Briton Ferry Athletic A.F.C. in 1926 when playing in the. Swansea and District Football League. Promotion was gained to the second division of the Welsh League in 1932.After the Second World War "The Ferry gained promotion to the first division of the Welsh League in 1947, albeit for one season only.
Despite the Club's mixed fortunes in the 1950's and 1960's it built up a fine sporting tradition and produced three full Welsh Internationals in Roy John, Harold Williams and Carl Harris.
In 1987 Mr. Graham Jenkins, a life president who played for the team between 1951 and 1955 and whose grand-father, Mr. James Taylor, was a founder member of the club became Chairman of the Club and between 1995 and 1997 he under-took the
re-building of the clubhouse, dressing-rooms, the visitors' lounge and the installation of flood-lights.
There is no doubt that the club's fine facilities were a factor when Mr. Carl Harris, the former Leeds United winger and winner of twenty four full Welsh Caps accepted the position of player-manager. The club enjoyed considerable success under Carl's leadership culminating in the team's promotion as runners-up to the new League of Wales. However the stay in the League was to be a short one when relegation followed at the end of the 1993-94 season.
Although the club retained its status has one of the most established teams in the Welsh league culminating in retaining their first division status for many years they were never able to reach the heights archived in their glory days and a succession of poor seasons culminated in their relegation to the third division of the Welsh Football League. Comparative youngsters compared to their counterparts at the Old Road, Llansawel Football Club were only formed in 1985 by a group of fathers who's children were playing junior football for Giant's Grave Boys Club. It has been over 20 years since we entered the then old Division Five of the Neath and District Senior League and the club has successfully rose through the ranks culminating in 2005/2006 by becoming the first team in the 75 year history of the Neath League to complete the treble twice.
2005/2006 proved to be a landmark season which saw the club win 6 trophies including the Premier League, Premier Cup, Open Cup, Borough Cup, Rose Bowl and 75th Anniversary Trophy. A great season was capped with Llansawel’s gaining promotion into the Welsh League. Llansawel spent three seasons in the Welsh League before the decision was made to amalgamate with Briton Ferry FC.
After extensive discussions in the Summer of 2009 it was agreed that Briton Ferry and Llansawel Football Club would merge to form Briton Ferry Llansawel AFC.
It has been evident during the past months of consultation that everyone associated with the new club is determined to grasp the opportunities this merger provides and maximise its potential ensuring that the new infrastructure provides a foundation for controlled growth ensuring a bright future for everyone associated with Briton Ferry Llansawel AFC.
