Anyone taking out loans for a PhD in the UK is a fool. Not only are our PhDs generally less well regarded than those from the EU and US, but there is also an abundance of grant funding available. If you can't get paid as part of a grant (and hence have fees taken care of) for a PhD here, then either the field of study has little economic value, or you are not considered good enough.
