I need to buy a longer ethernet cable than the one supplied by BT. It is a white cable with yellow ends. My hub is in one room and TV in another. I need approx 25m - is there any distance over which I will not be able to get my extra and BT Sports channels?

Yes, cat5e or cat6 cable should work fine over that distance.
For a little extra you can get shielded (a.k.a. screened) ones to cut down possible interference from power cables etc.
You do not want a cross-over cable. You want a standard patch cable.
Search Amazon for something like '30m cat5e shielded' and you'll get the idea.
