You need to have an H2h box, which is dual sat/cable, you also need an active Virgin connection, broadband is the easiest way (supplied by Virgin) and you then need a line for this.........depends whether you want to spend money on a new box and also if you dont have an active connection with them you would also need to sort this out.....so it may be cheaper to go for IPTV, depends on what you want.
I have an active virgin connection and I was going to try and ebay my H2s in the hope of buying an H2h, no doubt ebay are flooded with these boxes now!
