London 3 North West

London 3 North West is a level 8 league within the RFU league structure and is made up of teams predominantly from north-west London and Hertfordshire. Promoted sides tend to move up to London 2 North West while relegated teams drop to Herts/Middlesex 1. Each year all clubs in the division also take part in the RFU Senior Vase - a level 8 national competition.

Teams for 2021–22
The teams competing in 2021-22 achieved their places in the league based on performances in 2019-20, the 'previous season' column in the table below refers to that season not 2020-21.

Old Merchant Taylors', who finished 9th in 2019-20, withdrew from the league in November 2021, consequently it will be completed with eleven teams.

Season 2020–21
On 30 October the RFU announced that a decision had been taken to cancel Adult Competitive Leagues (National League 1 and below) for the 2020/21 season meaning London 3 North West was not contested.
