Born in Hertford, Bentley started his playing career with Aveley before moving on to Enfield in August 1998. He later moved to Aldershot Town, Gravesend & Northfleet (where he won Player of the Year in 2002–03) and Dagenham & Redbridge. On 15 January 2004, he stepped up into The Football League when he signed for Southend United, where he made 93 league appearances including 23 as a sub. He also scored 12 league goals including five in his last season at Roots Hall and was involved in two consecutive promotions.
He was offered a new one-year contract to stay at Southend, but opted to go for the security of a two-year deal at Gillingham, signing for them on 22 May 2006.
After coming second in the Player of the Year awards for the 2009–10 season, Bentley signed a new one-year contract for new manager Andy Hessenthaler with a clause stating that if he played a certain number of games it would be extended for another season, taking him to the end of the 2011–12 season.
On 11 May 2011, Bentley was released by Gillingham after serving five seasons with the club, after the club failed to gain promotion from League Two. He subsequently joined Hayes & Yeading United. Following Jamie Hand's departure to Luton Town in early September, Bentley was appointed club captain.
In June 2013, Bentley signed for Conference South club Boreham Wood. Bentley signed for Wealdstone on October 2013, to help with the club's push for promotion to the Conference South. Bentley left the club by mutual consent in the summer of 2014.
Bentley was appointed as player/assistant-manager alongside his role as a coach at Grays Athletic following the departure of manager Jody Brown and a number of coaches. He was then promoted to player/caretaker-manager in January 2015, before being given the job until the end of the 2014–15 season.
