Well, sort of. Some treatments are free. Some other treatments are not covered at all by the NHS, which counterintuitively makes those conditions more expensive to treat in the UK than they would be in the US.

> longer life expectancy

Life expectancy is a horrible way to compare healthcare systems, because there are far too many confounding variables to draw any meaningful conclusions. In reality, factors such as genetics, economic history, and demographics will overpower any effects that healthcare delivery could possibly provide.

> and better health outcomes

Not quite. The UK scores better on some healthcare outcomes, but it scores dramatically worse on others. For cancer treatment, in fact, it's one of the worst in Europe, and far behind the US. (This has been demonstrated by a series of studies that have been replicated multiple times over the past 20 years, the most recent being published only one year ago).
