Question: who pays medical bills in great britain where does the money come from to pay these bills?
Answer: general taxation, taxes

Wales each have their own systems of private and publicly funded healthcare, generally referred to as the National Health Service (NHS). With largely private providers, this also fits into the 'Beveridge Model' of health care systems, sometimes considered to be single-payer, although unlike Scandinavia, there is a more significant role for both private coverage and providers. Each country's having different policies and priorities has resulted in a variety of differences existing between the systems. That said, each country provides public healthcare to all UK permanent residents that is free at the point of use, being paid for from general taxation.
