Tan started out in kickboxing at the age of 15 before studying Brazilian Jiu Jitsu and MMA. It is said in previous interviews that Tan's inspiration to study Jiu Jitsu and MMA was through watching Rickson Gracie's Choke documentary.
Tan has travelled extensively to pursue training in mixed martial arts. He has trained with Brazilian Jiu Jitsu black belt and Pride Veteran Chris Brennan at the original Next Generation Fighting Academy, California. On his return to the United Kingdom, Tan co-created Next Generation MMA  UK in Liverpool. Tan currently teaches and trains at The MMA Academy Liverpool with Thai Boxing Champion Peter Davies.
On 5 December 2012, Tan was awarded his black belt in Brazilian Jiu Jitsu from SBGi Vice President and BJJ Black Belt Karl Tanswell of SBG Mainline, Manchester.
Mixed martial arts career
Tan began his career on the local show in Liverpool, known as Cage Fighting Championships & Cage Gladiators, defeating opponents such as Joey Van Wanrooy and Leslee Ojugbana. At this time Tan was not a prominent figure on the British MMA scene as he was only fighting in local shows. However this changed when he agreed to fight London's Alex Reid at the Manchester Evening News Arena on the "WCFC: No Guts, No Glory" event. Tan took the fight on two hours notice and some interviews state that he was actually in the middle of a McDonald's feast when he received the call. Tan dominated the fight both standing and on the ground earning a decision victory. Tan's first defeat came against Jim Wallhead who hails from Leicester and is a part of Team Rough House in Nottingham. Over a tough three round battle the judges scored a split decision victory for Wallhead.
Tan had to take time off after the Wallhead fight due to a knee injury and was not able to compete until mid-2007. Tan signed with the UFC in 2007. In his debut he fought at UFC 72 against former pro boxer Marcus Davis. Tan came out with sharp Muay Thai skills landing leg kicks and high kicks on Davis. However a brief exchange from the pair saw Tan get dropped by a right hook which prompted Davis to land further shots before referee Yves Lavigne stopped the bout at 1:15 of the first round.
Tan came back stronger defeating Brazilian Jiu Jitsu black belt Alexandre Izidro. Izidro was a recognized fighter in the UK and the former Cage Warriors Lightweight Champion. Tan dominated the fight outstriking Izidro on the feet and landing effective ground and pound from the top on the ground, where he had him in an armbar. Tan took a unanimous decision.
