Jetset
I believe that EZ are unlikely to be flexible about age, but you could always give it a go. Don't forget that this scheme is not limited to EZ, though. JMC are also involved, and their age limit is 26/11/30 at date of application. You can also apply for a place in your own right through CTC-McAlpine. It would be unsponsored to begin with, but they wouldn't take you on if they didn't believe they could place you.
