The South London Demons began in the Social Division in 2007, winning the inaugural flag.

The club now fields the highest number of players picked from the London league to represent their country in the Great Britain Bulldogs.

With the number of Australians looking to play in London increasing, in 1998 Martin Tunley and Sam Percy devised the idea of starting a second team, the Clapham Demons.

This grade started with thirds sides from the big clubs in London, the seconds of Wimbledon, and teams from further afield such as Bristol, Reading, and Nottingham.

In 2015 The Wandsworth Demons added a fourth team to their playing line-up, joining the inaugural AFL London women's league.

And in 2017 The Wandsworth Demons were the first club in London to add a second women's team and help form the Women's Conference division, making Wandsworth Demons the only five team club in AFL London.
