This league was founded in 1978 by Jim Roberts, Junior Organiser at North Middlesex Golf Club. He was worried that talented youngsters were being denied the opportunity to develop their game through outside competition. A total of 8 local clubs were invited to compete in a matchplay competition for a cup that a member of North Middlesex G.C. donated.
The following year the first competition was held with North Middlesex becoming the first champions. Over the years, membership of the league has risen to as many as 26 with a total of 31 different clubs having taken part at one time or another.
Jim died in 2000 aged 84 and the league was taken under the chairmanship of Marylyn Fuller. In 2020, Marylyn and her husband Ed moved to the South Coast. County Secretary of Middlesex Golf suggested that as they are the governing body for amateur golf in the County he felt it was right that they take over the Friern League. He hopes that the County's resources and reach can help restore the league's former status
The league is primarily open to any club in Middlesex that wishes to join but nearby clubs may compete by arrangement. The clubs in the leagues play each other both home and away with points being awarded for a win or a halved match. The winners of each league compete in a final and the runners-up play off in a 3rd/4th place match on neutral courses.
The League is open to male and female golfers under the age of 18 on the 1st of January of the current year and with maximum handicaps of 36.4.
