Clancey started her modeling career since 2006. During that year, she participated in the Living TV's Britain's Next Top Model. In the second cycle of that competition, she was included as one of the thirteen finalists in the competition, competing over 10 weeks for a modeling contract. She made it to the final runway show with fellow contestant Lianna Fowler, but she wasn't lucky enough to win it. What she gained was her career in modeling and her career continued to blossom from that day on. It is expected that she is earning a huge salary from her modeling career but her actual real time net worth is unknown to the press.
