I just looked into it and I think I could get the Sky Stream service for £46 a month....... (which includes netflix), but our internet speeds are "only just" fast enough: we're too far from any exchanges to get regular broadband connections* and so we have a 4G modem/router instead. It's "fast enough" for most things - but the Sky Stream Puck legal bit recommends 25Mbps minimum.... we only just get that!
Need to think about it a bit more.....
* When we moved here I had a conversation with BT that went something like this :
BT: Your residence is over 4kms from the nearest exchange, we can't guarantee anything more than about 2Mbps connection speeds.
Me: Well, that's barely enough speed for basic internet, So - what do you recommend can be done about that?
BT: Move house.
(absolutely true).
