Use an American RV TV & Freeview Box
You have an alternate path if you are willing to import a TV from the USA.
Currently you can obtain 12v flatscreen Digital RV TV's in the US upto 26inch (I also believe you can get 32" sets),
The tuner is of no value to you. However if you attach a Freeview box (I believe Maplins sell one which is 12V) you can output through the HDMI socket to the TV. This will then give you UK broadcast TV. Obviously Analogue TV would not be available.
