I suggest London External University. It’s much cheaper (3500 pounds and less)

Try a reputable university. Every major college or university has a distance education program. It runs through regular admittance, but when registering for classes, sign up for distance ed (includes internet courses, correspondance courses, and broadcast courses).
Seriously, it depends on how much can you afford. AIU and University of phoenix are great school when one can afforded it.
