Tait did an interview with 'MMA Prospects UK', where he describes that his inspiration in taking up martial arts was 'Teenage Mutant Ninja Turtles, Power Rangers and hyper activity'. He also mentions where his nickname 'Capcom' comes from, his early MMA career amongst other things.

MTV UK have done a documentary on MMA in the UK, with Tait, Jimi Manuwa, and Jack Marshman being filmed in the build-ups of their next fights and the training and lifestyles involved.

Tait made his professional debut against Lightweight John Brightwell, whom he defeated via armbar in the first round. Three weeks later he made his highly anticipated UCMMA debut against Dino Gambetesa, which Tait won by knockout via a devastating crescent kick and was nominated for knockout of the year.

Tait received his first title shot shortly after his win over Gambetesa, but was takeon down, out-wrestled and his impressive striking skills were rendered useless on the ground by James Lutman. However, Tait worked and trained hard on his wrestling and BJJ skills after his defeat to Lutman, and was rewarded with another title shot, this time for the UCMMA Featherweight title, where he was able to demonstrate these skills effectively.

On September 17, 2011, Tait defeated Nathan Beer by TKO (spinning backfist and punches) to win the UCMMA Featherweight Championship.

Tait next faced face Spencer Hewitt at UCMMA 26 - The Real Deal. He has decided to vacant his newly won Featherweight title so he can compete at his more natural weight at 135lbs and go for the Bantamweight title. He lost 10 seconds into the first round when Tait was caught with a punch.

He rebounded from that lost when he defeated Huseyin Garabet by submission at UCMMA 28.

Tait next fought Jody Collins at UCMMA 31, on December 1st. After an exchange of punches, the fight went to the ground were Tait showed his improved grappling skills and was able to transition to a Toe Hold. Collins submitted and was found to have broken his leg due to the Toe Hold.At UCCMMA 33, Cory  rematched Hewitt and ended  up knocking him out in the 1st round.

At Cage Warriors 64, Cory Tait faced of against James Pennington in the main event. James Pennington may have had the right idea against Cory Tait early in their Cage Warriors 64 main event. But Tait had other plans. He fought through Pennington’s early takedown, then managed to latch on to his neck midway through the fight. That was all Tait needed for a guillotine choke win that seemed to have Pennington in shock.

The vacant bantamweight title is was up for grabs as Cory Tait (8-2) fought Toni Tauru (9-1-1) at Cage Warriors 72. Toni Tauru’s mix of overwhelming offensive pressure and relentless grappling was the difference maker en route to a fourth-round submission of Cory Tait to capture the vacant Cage Warriors bantamweight championship.
