When Free Healthcare Isn’t Actually Cheaper
I recently heard about a guy named Devon who took a job in London after moving from Austin. He budgeted rent, National Insurance, the exchange rate on his savings, and everything else he could think of. For healthcare, he budgeted zero. The NHS is free, he figured, so that was one line item he wouldn’t have to worry about anymore.
Eight months in, he was paying for private health insurance through his new employer and wondering why “free” hadn’t turned out to mean what he thought it meant.
The assumption almost everyone makes
“Free at the point of use” gets shortened in people’s heads to just “free.” It isn’t. Someone is always paying for healthcare; the only question is how and when.
In the U.S., you pay through a premium, a deductible, and whatever your plan doesn’t cover. In a country with a national health service, you pay through taxes and payroll contributions whether or not you ever set foot in a hospital.
Neither system hands you care for nothing. They just collect the money on different schedules, which makes the true comparison a lot harder than “premium versus free.”
What each system actually charges you
In the U.S., the average annual premium for employer-sponsored family health coverage is $26,993. Employers typically cover most of that, but employees still pay an average of $6,850 a year through payroll deductions, on top of an average single-coverage deductible of roughly $1,886. Many plans also carry an out-of-pocket maximum well above $3,000 before insurance covers everything.
In the U.K., there’s no premium bill for the NHS. Instead, most employees pay Class 1 National Insurance contributions: 8% on earnings between £12,570 and £50,270, and 2% above that.
National Insurance is one of the mandatory payroll deductions that helps fund the broader public system alongside general taxation. It isn’t a one-to-one replacement for a health insurance premium since it also supports the state pension and other public benefits. But it is a real deduction from every paycheck, and it’s part of the answer to the question, “How is this actually paid for?”
These aren’t identical measures. A U.S. family premium and an individual’s National Insurance contribution aren’t directly comparable, but they illustrate the different ways each system collects money from working households.
Where it gets complicated: the cost of waiting
Here’s the part that caught Devon off guard.
The NHS is free at the point of use, but “at the point of use” assumes you’re willing to wait for that use.
As of 2026, the NHS waiting list in England sits at roughly 7.2 to 7.4 million cases. Median waits for many forms of elective treatment remain well above pre-pandemic levels, while some patients continue waiting more than a year. How long any individual waits depends heavily on the specialty and the stage of care being measured.
That wait time is part of why private medical insurance has been growing in the U.K. not as a replacement for the NHS, which most people continue to rely on for the vast majority of their care, but as an option for those who want faster access.
Private, insurance-funded hospital admissions reached record highs in 2025. At the same time, more U.K. employers began offering private medical insurance as a standard benefit, in part because some staff preferred not to wait for specialist referrals or elective procedures.
Devon’s new employer was one of them. He didn’t go looking for private coverage. It showed up as a line on his offer letter, and once he understood why it was there, he understood why several people on his team had opted in, even though plenty of others relied entirely on the NHS.
So the honest picture isn’t “the U.K. pays nothing and the U.S. pays a fortune.” It’s that the U.K. builds a base level of healthcare funding into everyone’s paycheck through National Insurance, and some people particularly through employer benefits choose to pay again for private insurance when faster access to specialists or elective treatment matters to them.
What the real comparison looks like
| Cost Layer | United States | United Kingdom |
|---|---|---|
| Base funding | Employer + employee premium (family average $26,993/year; employee share ~$6,850) | National Insurance: 8% of earnings between £12,570–£50,270, then 2% above |
| Point-of-use cost | Deductible (average ~$1,886) plus out-of-pocket maximum (often $3,000+) | Typically $0 at the point of use |
| Wait for non-urgent care | Usually measured in weeks, depending on provider network and scheduling | Well above pre-pandemic norms; some specialties exceed one year |
| Common workaround | Choose a richer (more expensive) insurance plan | Employer-provided or self-paid private medical insurance |
Neither column is free.
One front-loads the cost into a bill you can clearly see. The other spreads it across payroll taxes and then, for some people, adds a second bill for those who’d rather not wait.
On the other hand, many people moving to the U.K. discover they spend far less time worrying about catastrophic medical bills. The NHS removes much of the financial uncertainty that comes with deductibles, provider networks, and surprise medical bills, even if it doesn’t eliminate every healthcare cost.
That’s a real tradeoff, not just a footnote, and it’s worth weighing against wait times rather than treating one country’s system as simply “better.”
The real formula before you assume “free” means “cheaper”
True Annual Healthcare Cost =
Mandatory Contribution (Premium or Payroll Tax) + Likely Out-of-Pocket Spend + Probability-Weighted Cost of Skipping the Wait
That third term is the one people moving abroad almost never price in, and it’s often the one that determines whether “free healthcare” actually saves money or simply moves the bill to a different month.
Run your own numbers
Healthcare is one more variable that changes the real math of a move, alongside taxes, housing, and every other cost that determines what relocating actually looks like once you arrive.
If you’re comparing a move from the U.S. to the U.K., or any move where taxes, healthcare, and cost of living all change at once, run your own numbers before assuming one line item tells the whole story or that a “free” system automatically means a cheaper one.

Have you budgeted for healthcare during a move and been surprised, in either direction? I’d love to hear which country, and what the real number turned out to be.
