Broadfoot started playing rugby for Whitgift School, where he won the U15 Daily Mail Cup in 1999,[6] before he was signed to London Irish's academy[7] where he quickly rose through it, eventually becoming part of the London Irish squad while still a student at Cambridge University.[8] From there, he moved to Leicester Tigers and played for their first team in the English Premiership as well as playing on loan for Bedford Blues. After a lack of opportunities at Leicester, in 2008 he moved to Cambridge University R.U.F.C., where he became captain in the same year, to focus on his studies.[8]
While playing for Cambridge Broadfoot made a brief return to his original club, London Irish, where he was called up to provide cover to the first team squad.[8] In 2010 after graduating from Cambridge University, he moved to Richmond F.C. in order to also work as a commodities trader in London.[4] In 2011, he moved to Jersey[9] where despite Jersey being a full-time club, he remained a part-time player.[10] In his debut season for Jersey, he and teammate Michael Le Bourgeois were listed as two of the top ten kickers in National League 1 and helped his club win the league title and promotion to the Championship.[11]
In 2013, as Jersey moved toward becoming a fully professional championship team, Broadfoot took a year out of the game and left the club.[12] In 2015 he returned to league rugby, signing for Old Elthamians in National League 2 South.[13]
