Herts/Middlesex 5

Herts/Middlesex 5 was a tier 13 English Rugby Union league that was organized by the London and South East Division Rugby Football Union. It was the fifth division competition for clubs in Hertfordshire and parts of north-west London that traditionally belonged to the historic county of Middlesex. The league was split into two regional divisions - Herts/Middlesex 5 North and Herts/Middlesex 5 - with promoted teams moving up to Herts/Middlesex 4 and there was no relegation as it was the lowest level in the region. Herts/Middlesex 5 only lasted one season before being discontinued, with all teams being transferred into Herts/Middlesex 4.
