Middlesex 1 (1992–1996)
The creation of Herts/Middlesex at the beginning of the 1992–93 season meant that Middlesex 1 dropped to become a tier 9 league. The introduction of National 5 South for the 1993–94 season meant that Middlesex 1 dropped another level to become a tier 10 league for the years that National 5 South was active. Promotion was into the new Herts/Middlesex league while relegation continued into Middlesex 2. The merging of the Hertfordshire and Middlesex regional divisions at the end of the 1995–96 season meant that Middlesex 1 was cancelled.
