I am seeing the LNER adverts here in North Wales.
The previous Virgin ones were at least generic and worked for both VTWC and VTEC.
We also get the GWR Famous 5 adverts, which are about as useful to us up here as those for bank holiday furniture sales in Bridgend!
It hasn't been explicitly mentioned, but I do assume you and others are talking about ITV?
Channel 4 has a couple of mega regions for advertising, I think 2 or 3 regions covers all of England, but every other channel has only a national version
