On 16 April 2014, Spelthorne Sports were crowned Combined Counties Division One Champions with a 2–1 win away to Epsom Athletic.

The Spelly also won the RPM Records Division One Challenge Cup against Staines Lammas at Windsor FC on 5 May 2014.

A single second half Lee Staples goal was enough to make sure The Spelly lifted the trophy, winning the league and cup treble in the process.

The team went on a phenomenal 46 game unbeaten run in all competitions that season, beating teams in cup competitions from higher divisions such as Frimley Green, Staines Town (on pens), Walton Casuals, Wembley, and Epsom & Ewell (on pens).

The lads then suffered their second defeat of the season to the same opposition when the sides met again 3 days later in the Cherry Red Records Premier Challenge Cup Final, again losing 1–0.
