To date, he has had 10 fights since his first professional fight in 2005, with a record of 3 wins and 7 losses. His only wins have come from a referee stoppage against Mindaugas Arbocius, a TKO win against Nigel Whitear and a knockout against Mark Carling. Barrett has fought as a welterweight, fighting mostly for the now defunct Cage Rage and currently for UCMMA.
For many weeks, Barrett had been calling out Alex Reid, following him to his gym and demanding to fight with him, and attempted to fight him inside the UCMMA cage during an interview between Reid and UCMMA owner Dave O'Donnell. In one incident, Barrett took a megaphone down to a restaurant on Old Compton Street in Soho to interrupt Reid and his girlfriend Chantelle Houghton, who were dining there. Reid's security went outside to ask him to leave Reid alone, but refused to move. This then prompted Reid to walk outside, and ended up with Barrett attacking Reid's security, attempting to go for Reid. After being pulled away from each other, Barrett vowed he would 'follow him everywhere until he signed the contract'. Reid verbally agreed. Barrett faced Alex Reid in a Middleweight 'Super Title' fight at the UCMMA 22 – Warriors Creed event on 6 August 2011. This was his first fight since his KO win over the debuting Mark Carling and his Middleweight debut. During the press conference, Barrett apologised for his antics in obtaining the match-up with Reid, discouraged anyone else from doing the same, and vowed to knock Reid out. At the end of the conference, Dave O'Donnell asked them both to square up and pose for photos. Barrett put his hands up as requested, but Reid refused, instead standing up close to Barrett's face, and Barrett pushed him away. Reid began walking away, but O'Donnell asked him to come back, which he did, and both men squared up. Because of Barrett pushing Reid, Dave O'Donnell vowed to take 10% of Barrett's fight purse for every time he engaged in antics like that. During the weigh-ins the day prior to the fight, both men weighed in at just under the 185 pound mark. For the camera shot of both men squared up to each other, Reid again refused to put his hands up, and this time, Reid kissed Barrett on the lips, which infuriated Barrett, who had to be held back by UCMMA officials. Reid was laughing at his reaction, and vowed he would apologise 'after the fight'. Barrett lost the fight to Reid in the first round due to submission via triangle choke.
Conviction
In June 2012, in a planned police operation, Barrett was arrested with another man, Kayhan Kiani, after an illegally supplied gun was passed to a man in a car. Weapons were seized in the operation. Barrett was charged with firearms offences. In 2013 he pleaded guilty and was sentenced to six years and a half years imprisonment.
