Then your other option is to get VM broadband, and a cable box.
If you get an Enigma 2 box it can be tweeked to run IPTV if cable goes tits up.
Something like this
Xtrend ET7100v2 HD 1x DVB-C/T/T2 Linux Full HD H.265 PVR 1080p Digital Cable / Terrestrial Receiver
Virgin are making changes to their Sports HD channels at the moment and it is likely
the rest of the HD will follow at some point.
Nobody knows how long SD will last, could be weeks could be years.
Finally, you may be lucky if your house has had cable in the past the feed may still be live
and you can then use any BB package.
Safest way is just to sign up for Virgin BB only then you are gauranteed a live feed
