Upgraded package yesterday and new 350Mb speed (at least via ethernet) and 'Biggest TV' channels all working today.
There is no email about activating Netflix, which is included, nor any way to activate it via the account webpage.
I note that the final paragraph of the FAQ above states "Please do not try to activate Netflix via your Set top Box, if you are not on one of the bundles above, as this may result in Netflix billing being added to your account, which is a chargeable service."
That clearly means that if you ARE on a bundle with 'Netflix standard' included then you CAN add it via the Set top box, though would be important to select 'standard' and not 'premium' which is the default. My concern however is that it may have been written by someone who is incorrectly informed or with a suboptimal command of English. The prospect of battling with Virgin's customer service avoidance team to resolve an incorrect charge is too dreadful to run the risk without prior confirmation that it is correct.
