Regional 1 South West honours
In the first season of the English rugby union league pyramid, sponsored by Courage, there was four, tier five leagues. The geographical area for teams in South West Division One covered an area of south-west England from Oxfordshire and Berkshire in the east to Cornwall in the west. There were eleven teams in the league and they played each team once, giving each team ten matches. The other tier five leagues were London 1, Midlands 1 and North 1. This system prevailed for five seasons, and in 1992–93 the number of teams increased from eleven to thirteen. The following season the league was reorganised and the four tier five leagues became two; National 5 North and National 5 South. After three seasons, in 1996–97, a further reorganisation occurred, and there was a return to four, tier five leagues; with South West Division One covering the area of south-west England from Berkshire westwards. This system prevailed until 2009–10 when the number of teams was increased from twelve to fourteen and renamed National League Three South West. There was a name change for the beginning of season 2017–18 when the division was renamed the South West Premier.South West 1 (1987–1993)
