Following the RFU's Adult Competition Review, from season 2022-23 it adopted its current name Counties 3 Kent.

Each year some of the clubs in this division also take part in the RFU Junior Vase - a level 9-12 national competition.

This was the first season following the RFU Adult Competition Review[2] with the league adopting its new name of Counties 3 Kent.

The cancellation of National 5 South at the end of the 1995–96 season meant that Kent 1 reverted to being a tier 8 league.

The introduction of London 4 South East ahead of the 2000–01 season meant Kent 1 dropped to become a tier 9 league with promotion to this new division.

Since the 2000–01 season there has been a play-off between the runners-up of Kent 1 and Sussex 1 for the third and final promotion place to London 3 South East.
