Okay, you have CCTV evidence of the alleged incident, Get the insurance details from him tomorrow, and go through them, either way he will still have to fork out for the damage (his insurance excess), it doesn't matter if he has only been driving for a year, he should still have insurance to cover any eventuality.
One thing though, do a check of his reg number through (
CLICKY), oh and be careful about your insurance approved bodyshop they might just turn round and say that you wont get the car repaired, they might write it off, it has been known for such a small dent, scratch etc.
