Your regional ITV programmes are available on channel 103.
ITV Anglia is not available in HD in the Anglia West region on any TV platform so channel 113 will give you the nearest region that is (in your case, ITV Meridian East). Until ITV upgrades the studio playout facilities in Norwich, this will continue to be the case.
