As we enjoy this program, I have further reviewed its availability just now.
At the moment it looks like this is one of those Walter Presents series where only the first episode is available on the TV channel and all other episodes available exclusively on the All4 app (where you can’t avoid the adverts).
Virgin Media does not have access to the All4 app on their boxes, just a catch up service for broadcast material.
Contrary to what I said above, all episodes of series 2 are now available on the All4 app on my iPad and my Smart TV.
Enjoy.
