Middlesex 4 (1992–1996)
The creation of Herts/Middlesex at the beginning of the 1992–93 season meant that Middlesex 4 dropped to become a tier 12 league. The introduction of National 5 South for the 1993–94 season meant that Middlesex 4 dropped another level to become a tier 13 league for the years that National 5 South was active. Promotion continued to Middlesex 3 but the cancellation of Middlesex 5 at the end of the 1991–92 season meant there was no longer relegation. The merging of the Hertfordshire and Middlesex regional divisions at the end of the 1995–96 season meant that Middlesex 4 was cancelled.
