It is important to note that "debt" is perhaps a misleading term when considering student loans in the UK. The money must be repaid as a percentage of earnings (9% of everything earned above £27,295, so if you don't earn above £27,295 you don't pay anything), and after 30 years any remaining debt is wiped. In this way the "debt" is much more equivalent to a tax than a loan.

Money Saving Expert have a very good guide that details this further [1].
