Research council, and supplemented it with teaching, tutorials and lab classes. Had about 6k of tax free funding, plus what I could earn teaching. Worked out fine, I actually felt quite flush after living off 3.5k a year as an undergrad.
Can I ask what your area of study is?
Also, and I'm not bring a downer, just sharing my experience...DO NOT do a phd without a solid source of funding unless you know you're going to find it easy to find work. Especially if you are in debt from your first degree. There are a LOT of unemployed PhDs out there. I ended up leaving academia, and even with an absolutely stellar academic record, a serious work ethic and good people skills, it took me almost five years to get back to my postdoc salary.
I'm a scientist by training, and now that I work in the corporate world (my soul is preserved in a jar, I can have it back when I leave) I see there is a presumption against hiring PhDs. They are seen as unworldly, too independent and un mouldable to the corporate hive brain. I had to combat that stereotype when I moved careers.
Also, if you do end up doing a phd, the most valuable bit of advice I can give you is this : network. From week one,you need to be cultivating contacts. Do not blithely sail through with your head in your research and expect the perfect job to pop up once your viva is done. It doesn't work like that.
Also be strict with yourself. Thesis gets written up as you go, keep references in order, do not stay an extra year on zero pay to 'just do a few more experiments.' Pick your supervisor/ lab very carefully. Speak to others in the lab and vet your supervisor for any hidden signs of insanity.
