Following their sponsorship of the Kent League Cup for the 1984–85 season, cable-making company Winstonlead extended their sponsorship to cover the League and this ran for 15 seasons between 1985 and 1999 during which period the competition was styled as the
Winstonlead Kent League. They were succeeded by brewing company
Bass as sponsors for three seasons during which the league was titled the
Bass Brewers Kent League. In 2002 Kent based travel agency business Go Travel were the sponsor with the competition known as the
Go Travel Kent League. The sponsor changed in 2005 to the Kent on Sunday newspaper and for a single season, 2005–06, the league was known as the
Kentish Observer League. There followed two years without a title sponsor until 2008 when it was sponsored for two seasons by
Bulmers and named the
Bulmers Cider Kent League. For the 2010–11 season, training and consultancy business Safety Net Associates were the sponsors with the league known as the
Safety Net Associates Kent League. Thereafter for two seasons commencing with the 2011–12 season the league was sponsored by Hürlimann Sternbräu lager (brewed by Kentish brewers
Shepherd Neame) and billed as the
Kent Hurlimann Football League. After six seasons without a title sponsor, in November 2019 shipping company Sea Pioneer was named as sponsor with the competition known as the
Sea Pioneer Southern Counties East Football League – this arrangement ceased with the interruption of football in March 2020 owing to the
COVID-19 pandemic. The league next announced a sponsorship agreement in June 2024 with Tunbridge Wells based property management firm Presence & Co., with the league to be known for the following two seasons as the
Presence & Co. Southern Counties East Football League. The League's knock-out cup competitions have intermittently attracted separate sponsorship: from 2011 to 2018 the Challenge Cup was sponsored by sportswear brand
Macron; the Reserves Section cup was known for the 2008–09 season as the HAUC (Highways Agency Utilities Committee) Reserves Cup and for the following two seasons to 2010–11 was sponsored by (infrastructure provider) Blu3. ==Current structure and teams==
