IP location is nowhere near accurate enough for this. Most people in Southern England would end up with ITV London like 90% of the time.

Realistically the only people with the capability of locating someone's exact address through IP data are law enforcement bodies, the security service and the ISPs themselves. I can't see ITV being given the appropriate powers under (R)IPA/GDPR to request that data for the purposes of making sure you're watching Calendar and not Central News...
