The Pineapple Dance Studios star said that he has already been impressed by a number of contestants.
Speaking on the National Television Awards red carpet, he is quoted by Entertainment Wise as saying: "I'm having lots of fun. It's something really easy for me.
"I only have to speak a maximum of 30 seconds and then I have to critique dance."
Spence added: "At the moment there are people that are standing out a bit more, like Matt Wolfenden, Jorgie Porter, Sebastian Foucan, Chico, Chemmy [Alcott] has got real fire and Heidi Range."
Dancing on Ice continues this Sunday from 6.15pm on ITV1.
