In a twist to regular ceremonies, the awards also honour 'Teen Heroes', teenagers who have been nominated for performing brave, inspirational or selfless acts.
The heroes were chosen by a panel of celebrities including Professor Green, Louis Smith and Jessie Ware, as well as Radio 1 DJs, journalists and youth organisation professionals.
There are also music, television and movie accolades to be won, with One Direction and The X Factor hoping to collect more gongs to add to their growing collections.
