Well, for a solo piano piece it sounds way too "programmed" so to say. You should have tried to humanize it a bit; if not the intervals, then at least the attack velocity of the notes (if available, different samples for the same notes would have added a lot of more life to the composition as well).
If you had had time to add in the other instruments as well, then I guess it could have worked in this state though.
Not to bad a song, and I don't claim to know what the "Regis and Kelly show" is, but I'm afraid it sounds a bit thin for a show theme. And also, not really a fitting genre for such a song at all (not that it wouldn't fit with other things though). But as said, I don't know what that particular show is all about, so maybe it is indeed fitting.
(I'm tired and should probably stop my rambling by now )
