Thurlow Nunn Football League

The Eastern Counties Football League is an English regional association-football competition, currently known as the Thurlow Nunn League for sponsorship purposes. Operated by Eastern Counties Football League Limited, it runs at Steps 5 and 6 of the English football league system across Norfolk, Suffolk, Essex, eastern Cambridgeshire and Hertfordshire, southern Lincolnshire, and parts of north and east London. Its senior structure comprises a Premier Division and First Division North and South, alongside an Under-23 Development League and Under-18 Youth Leagues. The league publishes fixtures, results, tables, player-registration guidance, competition rules and ground standards, and administers the League Challenge Cup. It is a league competition, not an individual club or county football association.
