In February 2022 Drifters RFC withdrew from the league with their fixtures liquidated meaning it will be completed with eleven teams. Due to the COVID-19 pandemic, the 2020–21 season was cancelled. The 2015–16 Berks/Bucks & Oxon Premier consisted of twelve teams; five from Oxfordshire, four from Berkshire and three from Buckinghamshire.

The 2014–15 champions Reading Abbey were promoted to the Southern Counties North along with runner-up, Swindon College Old Boys, while Phoenix were relegated to the Berks/Bucks & Oxon Championship. When league rugby began in 1987 this division (known as Bucks/Oxon 1) contained the following teams from Buckinghamshire and Oxfordshire: Originally known as Bucks/Oxon 1, it was a level 8 league for clubs based in Buckinghamshire and Oxfordshire. Promotion was to Southern Counties and relegation to Bucks/Oxon 2. The creation of National League 5 South for the 1993–94 season meant that Bucks/Oxon 1 dropped to become a tier 9 league. Promotion continued to Southern Counties and relegation to Bucks/Oxon 2. The cancellation of National League 5 South at the end of the 1995–96 season saw Bucks/Oxon 1 renamed as Bucks/Oxon and once more was a tier 8 league. Further restructing meant that promotion was now to Southern Counties North and relegation was to Bucks/Oxon 2. Bucks/Oxon would revert to its former name of Bucks/Oxon 1 for the 1997–98 season, remaining a tier 8 league.

Promotion continued to Southern Counties North, while relegation would be to the new Berks/Bucks & Oxon 2.

Promotion would continue to Southern Counties North, while relegation was to Berks/Bucks & Oxon 2.
