Brown came through the youth system of Brentford, moving up from the under–18s squad to the first-team for the 2006–07 season. On 22 August 2006, Brown had his first involvement with the first-team squad at as an unused substitute, at the age of just 16, in the 4–3 penalty shoot-out victory over Swindon Town, after the game had ended 2–2 in normal time, in the First Round of the 2006–07 League Cup. At the end of the 2007–08 season he signed his first professional contract with the League Two side. Brown was loaned to Southern League Division One South and West side Windsor & Eton to gain first team experience, making 25 appearances for the club. Brown made his competitive debut for Brentford on 2 September 2008 in the First Round of the 2008–09 Football League Trophy against Yeovil Town, which ended 2–2 and went to a penalty shoot-out. Despite being only 18 at the time, Brown saved a crucial penalty by Andre McCollin to allow "The Bees" to triumph 4–2. Despite this, however, Brown was released by manager Andy Scott on 6 May 2009 along with eight other players having failed to break into the first team.
Brown joined AFC Wimbledon in 2009. On 21 May 2011, he saved two penalties for the club in the 2010–11 Conference play-off final penalty shoot-out as they beat Luton Town to gain promotion to the Football League. He was named as the goalkeeper for the 2010–11 Conference Team of the Year. On 19 February 2013, it was announced that Brown had joined Conference side Woking on an initial one-month loan deal. Following his release, Brown signed for ambitious Conference South side Bromley. Following the club's signing of Alan Julian in January 2015, however, Brown joined Whitehawk on a month's loan. After making just one appearance for the Hawks, Brown returned to Bromley, and joined Hampton & Richmond Borough on loan.
