I had a look on my Youview system -
Interesting that where Series 1-4 and 6 are listed as box sets - series 5 isn't but is there if you do a search. That search reveals that only eps 1-7 and 10 are (currently) there - eps 8-9 , 11-13 are not present. The promotional trailer does say series 1-6 can be watched right now in Bt box sets.
