Like you say, scholarships are a possibility, and I would recommend looking at the university where you completed your undergraduate degree, as they might offer an alumni discount. I funded mine with a scholarship, but my plan for if I wasn't awarded a scholarship was to live at home with my parents. Finances would have been tight, but the loan would have just about covered train fares and tuition fees. This is of course reliant on you living close enough to a university that you would like to attend. I found that a lot of people on Masters courses had to live with their parents whilst studying.
The other option is working alongside your masters. Most people I knew who worked during their masters worked in part-time, evening jobs, or on zero-hour contracts so they could fit this in alongside their contact hours. I also know quite a few people who did their masters part-time, and sometimes distance learning, whilst also working in a full time job. Going part-time also meants that your tuition fees are split over the two years. You could also consider an MRes, which has lower tuition fees but also means that you might not have the same amount of support and structure that you would with a taught Masters. I also noticed at Masters level that quite a few people had parents who were in a positon to help them financially with tuition and living costs.
