The dancer, who is now a judge of a reality show of his own on Sky 1, said that the pressure has helped him and his fellow Diversity dancers to strive to improve.
Saying the show had "turned his life upside down", Ashley revealed "I've got two TV shows on the go on Sky with Got Top Dance and Ashley Banjo's Secret Street Crew. And Diversity are about to embark on our biggest tour yet.
"It's all arenas - it's crazy Were playing at The O2 to 10,000 people. Our lives have been turned upside down."
And as Britain's Got Talent prepares for the return for another series, Ashley told this year's hopefuls that it was up to them to make the most of their opportunity.
"You never forget the pressure! And that same pressure pushes me on even now to get better," he explained. "It's up to you to put in the right amount of hard work, be confident and know that you've done your best."
