The UK provides healthcare through the National Health Service (NHS), a publicly funded system that covers most medical treatment at no direct cost to patients. Roughly 79% of health spending comes from public revenues, primarily general taxation. You don’t need health insurance to see a doctor, visit a hospital, or receive emergency care. The system is available to all UK residents, and most services are free at the point of use.
How the NHS Is Organized
The NHS is not a single organization. It’s made up of hundreds of different bodies at central, national, regional, and local levels, each with different roles. In England, the system is organized around 42 Integrated Care Systems (ICSs), partnerships established on a statutory basis in July 2022. These bring together NHS bodies, local councils, and other organizations to plan and deliver health services for their geographic area.
Within each ICS, an Integrated Care Board (ICB) is responsible for deciding how NHS money gets spent locally, including which services to fund and where. On the ground, care is delivered through NHS Trusts (which run hospitals) and roughly 1,250 Primary Care Networks, groups of GP practices that work together with community, mental health, pharmacy, and hospital services to provide care closer to home.
Scotland, Wales, and Northern Ireland each run their own version of the NHS with slightly different structures, but the core principle is the same: tax-funded healthcare, free at the point of use.
Your GP Is the Starting Point
The first step for any non-emergency health concern is your general practitioner, or GP. Every UK resident registers with a local GP practice, which becomes their main point of contact with the NHS. Your GP handles everything from routine checkups and vaccinations to managing chronic conditions and mental health concerns.
GPs also act as gatekeepers to the rest of the system. In the UK, access to NHS specialists is generally only possible after a referral from a GP. If your GP thinks you need to see a cardiologist, an orthopedic surgeon, or any other consultant, they write a referral. You can’t typically book a specialist appointment on your own through the NHS. This keeps specialist services focused on patients who genuinely need them, though it can feel like an extra step if you already know what’s wrong.
Emergency and Urgent Care
For life-threatening emergencies like heart attacks, strokes, or serious accidents, you call 999. An ambulance may be dispatched, though calling 999 doesn’t always mean one will be sent. You might be told it’s safe to make your own way to A&E (the emergency department, known in other countries as the ER).
For urgent problems that aren’t life-threatening, the NHS 111 service fills the gap. You can check symptoms online at 111.nhs.uk or call 111 to speak with someone. The service assesses your situation and directs you to the right level of care, whether that’s a pharmacy, an urgent care center, a GP appointment, or A&E. If you need help for a child under 5, calling is recommended over using the online tool. A&E treatment is always free, regardless of your registration status or nationality.
What You Actually Pay For
Most NHS care costs you nothing. GP visits, hospital stays, surgeries, cancer treatment, and emergency care are all free. But a few services carry charges.
Prescriptions in England cost £9.90 per item. That’s per medicine, not per prescription slip, so if your doctor prescribes three medications, you pay £29.70. Some items are always free, including contraception and medicines prescribed during a hospital stay. Large groups of people are also exempt from charges entirely, including children under 16, adults over 60, pregnant women, and people on certain benefits or with specific long-term conditions. Scotland, Wales, and Northern Ireland have abolished prescription charges altogether.
NHS dental care uses a tiered pricing system. As of April 2025, a Band 1 treatment (checkups, X-rays, basic prevention) costs £27.40. Band 2 (fillings, root canals, extractions) costs £75.30. Band 3 (more complex work like crowns, dentures, or bridges) costs £326.70. Urgent dental treatment is £27.40. Finding an NHS dentist accepting new patients can be difficult in some areas, which is one of the system’s well-known pressure points.
Eye tests and glasses are not automatically free, though they are covered for children, people over 60, and those on low incomes.
Waiting Times
The NHS Constitution states that patients should wait no longer than 18 weeks from GP referral to the start of consultant-led treatment. In practice, many patients wait longer than this target, particularly for non-urgent procedures like hip replacements or cataract surgery. Wait times vary significantly by region and by specialty. Urgent and cancer-suspected referrals are fast-tracked through separate pathways with shorter targets.
This is the trade-off at the heart of the NHS model. You rarely pay out of pocket for treatment, but you may wait weeks or months for non-urgent specialist care. For genuinely urgent or life-threatening conditions, the system moves quickly.
Private Healthcare as an Alternative
Private healthcare exists alongside the NHS. Some people purchase private health insurance through their employer or individually, primarily to skip NHS waiting lists or to choose a specific consultant. Private care is most commonly used for elective procedures, diagnostics, and outpatient appointments rather than emergency treatment. Many consultants work in both the NHS and the private sector, so you may see the same doctor either way, just with a shorter wait privately.
Self-pay (paying out of pocket without insurance) has grown in recent years, particularly for procedures where NHS waits are longest. Common privately funded procedures include joint replacements, diagnostic colonoscopies, and certain cancer treatments. Private care doesn’t replace the NHS for most people. It supplements it for those who can afford faster access.
Healthcare for Visitors and Immigrants
If you’re moving to the UK on a visa, you’ll likely pay an Immigration Health Surcharge (IHS) as part of your application. This costs £1,035 per year for most visa categories, or £776 per year for students, their dependants, Youth Mobility Scheme visa holders, and applicants under 18. The surcharge is paid upfront for the full length of your visa, so a three-year work visa would cost £3,105. If your visa is for six months or less and you’re applying from outside the UK, you don’t pay the surcharge.
Once you’ve paid the IHS, you’re entitled to NHS care on the same basis as a UK resident. Short-term visitors without a visa (tourists, for example) are entitled to free emergency treatment and GP consultations, but hospital treatment may be charged at 150% of the NHS rate. EU citizens with a valid European Health Insurance Card (EHIC) or Global Health Insurance Card (GHIC) have some reciprocal coverage for necessary treatment during their stay.
