Uk student, wants to convert Masters obtained 30 years ago into a PhD. will be self funding, what is the rough cost. Labour history is the area of study.

The cost varies by university. You should look at the Registry website sections of the universities you are considering. At my (Scottish) university the total fee alone for such a humanities PhD would be about 11,000 pounds. That's either paid over 3 years if a full-time student, or pro-rata'd over a longer period if part-time. This cost is fees only, and doesn't cover additional expenses, such as buying books, out-of-pocket research costs (e.g. photocopying, microfilming, travelling to archives etc.) and - if studying full-time - living/maintenance costs.

Thanks for that info I'll look into that area.
