Help me plan funding for my masters

I'm going to university this coming September and don't want to take out a loan. My company will be paying for my tuition fees, so I just have to cover maintenance. So rent, food, travel etc. realistically, can the ~£15k I have saved up carry me through 2 years of paying rent and... Living? I'll be working part time as well as am expecting around £300-400 a month during this time as well. Do you think it's possible or should I just take out a maintenance loan?
