home, the thing to watch out for is if someone in the house is not a student. This happened to DS as they kept their flat on for a second year, at which point one had graduated and was working but wanted to stay. No problem, but they needed to agree in advance that he and he alone, was responsible for paying the CT.
If they want broadband it is worth looking at NowTV, part of Sky. You have a months rolling contract, far better than many who demand 18 months. Its not fantastically cheap but useful if you have bad mobile coverage or bad TV reception, as it all comes as a package. The problem is that, presumably deliberately, it is very easy to access paid for content like movies and sport.
