Ok taking in what ignition said about the 4 users maxing the ubr, and a few other thoughts, I have serious concerns about quality of the connection.
On the current tier levels the contention at ubr level seems to work out at under 20:1 which is quite acceptable. But with everyone on 10mbit that could mean contention of around 50:1 (based on around 200users on a ubr) ubr specs here I think ntl use eurodocsis

Now if any ntl bod can confirm, on the new speeds will effective contention ratio be around the same or am I right there is a marked increase, and if so will there be traffic shaping to protect gamers and people using live apps from latency problems.
