I have had virgin installed since November 2019 and the ITV new is for the Central area. I live on the border between Chesterfield and Sheffield and the ITV central areas doesn't cover any news areas that are relevant to me. Can the area be changed to ITV Yorkshire???
No, you cannot change the TV region you receive on cable. This is determined by the cable franchise headend you are downstream of. In your case this is Nottingham, which gets East Midlands ITV on 103 & West Midlands ITV HD on 113. Some of this area receives the East Yorks & Lincolnshire service on 870, but if this is not available you are stuck with what you have.
As a Very Insightful Person, I'm here to share my knowledge. I don't work for Virgin Media.
