Houses in Gwent can sell for £35,000. That's £140 a month. Council tax would be about £100 a month. Food - if just you, you could easily eat for £40 a week or £160 a month. £400 a month.

Water rates £50 a month
Electricity and gas, about £80 a month.

£530 a month. Add in house insurance, and a bit for a rainy day, and for £600 a month you could be buying a property in Gwent, eating and living in warmth.

Everything else is, frankly, a luxury. So, it's open to definition of what living comfortably is. I reckon you could live a minimal existence for £8000 per year. And, in 25 years, you'd own your own property. If you could get in a lodger, you could feasibly charge £100-£120 a week for rent and you'd be living on less than £4k a year.
