The National Health Service (NHS) is one of the UK’s most enduring institutions — admired at home, studied abroad, and discussed endlessly in politics, policy, and everyday life. For residents, it is often taken for granted: you fall ill, you call your GP, and you are treated without being asked for an insurance card or a credit card. For newcomers, however, the question of eligibility looms large. Can anyone use the NHS? Do students, workers, and expats receive the same entitlements as British citizens? And what about tourists who might need urgent care?

This guide explores those questions in detail, offering a comprehensive look at who can get NHS treatment in the UK in 2025. It examines the principle of “ordinary residence,” explains the rules for different groups — citizens, expats, students, and visitors — and clarifies how the Immigration Health Surcharge fits into the picture. For those moving to Britain or studying here temporarily, understanding eligibility is as important as securing housing or opening a bank account.

The Principle of Ordinary Residence

At the heart of NHS eligibility lies a deceptively simple legal phrase: ordinary residence. The NHS is not strictly a citizenship-based service; rather, it is anchored in whether a person is lawfully and habitually living in the UK.

To be considered “ordinarily resident,” an individual must:

• Live in the UK on a lawful and settled basis.

• Demonstrate an intention to remain for the foreseeable future.

British citizens, permanent residents, and those with indefinite leave to remain automatically meet this standard. For them, NHS entitlement is a matter of right. They are not asked to show proof of eligibility when accessing care; registration with a GP is generally sufficient.

For others, such as expats and students, eligibility is conferred through visa status and the Immigration Health Surcharge, effectively extending “ordinary residence” for the duration of their stay.

NHS Entitlement for British Citizens and Permanent Residents

For citizens and those with settled status, NHS access is comprehensive. This includes:

• Primary care: GP appointments, prescriptions (with standard charges in England), and referrals.

• Secondary care: Specialist consultations, hospital admissions, operations, maternity services, and emergency care.

• Preventive services: Vaccinations, screenings, and public health campaigns.

While certain services such as dentistry and optical care involve fees, the vast majority of treatment is provided free at the point of use. The system’s universality remains its defining feature: a wealthy executive and a low-income worker receive the same care under the same conditions.

Visa Holders and the Immigration Health Surcharge

For expats arriving under work, family, or study visas, the Immigration Health Surcharge (IHS) is the key to NHS entitlement.

• Costs in 2025: £1,035 per adult per year; £776 per child.

• Payment method: Upfront, at the time of visa application.

• Coverage period: The entire length of the visa, whether two, three, or five years.

Once the surcharge is paid, visa holders access the NHS on equal terms with residents. They can register with a GP, receive hospital treatment, and use emergency services without additional charges (beyond the standard prescription or dental fees).

For expats, this arrangement brings certainty: unlike private health insurance schemes, which often involve exclusions and tiers of coverage, the IHS is a one-off payment that opens the door to the entire NHS.

NHS Access for Expats Settling in the UK

Expats who move to the UK under long-term visas often find the NHS both familiar and unfamiliar. Familiar, because the absence of bills at the point of care feels liberating; unfamiliar, because waiting times can be longer than in insurance-based systems.

What expats should know:

• Registration with a GP is essential — this is the gateway into the system.

• Specialist care requires GP referral; one cannot book directly.

• Emergency services (ambulance, A&E) are always covered.

• Routine dental and optical care require payment, just as for UK residents.

For expats who later gain indefinite leave to remain or British citizenship, the NHS entitlement simply continues without interruption. The shift is administrative rather than substantive.

NHS Access for Students in the UK

International students are a large and important group in the UK. Their access to the NHS is straightforward:

• IHS requirement: Students must pay the surcharge as part of their visa application.

• Coverage: Once paid, they are entitled to the same NHS care as residents for the length of their course.

• Special benefits: Students under 18 are exempt from prescription charges in England, and eye tests are often free for younger age groups.

This system ensures that students can focus on their studies without worrying about unexpected medical bills. It also reinforces the UK’s reputation as a welcoming destination for international education.

Tourists and Short-Term Visitors

Visitors on tourist or business visas of six months or less are not entitled to free comprehensive NHS care. However, two principles apply:

• Emergency treatment is always provided: If a tourist has a car accident or sudden illness, they will be treated without hesitation.

• Non-urgent care may be billed: Visitors may face charges for hospital stays or outpatient treatment beyond immediate emergencies.

For this reason, the UK government strongly recommends private travel health insurance for anyone visiting on a short-term basis.

Regional Variations in NHS Entitlement

While the NHS is a national service, healthcare policy is devolved to Scotland, Wales, and Northern Ireland. The broad principle of ordinary residence applies everywhere, but specific rules vary:

• Scotland and Wales: No prescription charges.

• Northern Ireland: Prescriptions are also free; emphasis is placed on community health access.

• England: Prescription charges (£9.90 per item in 2025) remain, though many groups (children, older adults, those with chronic conditions) are exempt.

For expats and students, these variations may come as a surprise — the “UK NHS” is not entirely uniform.

NHS Treatment Eligibility: A Matter of Fairness

Eligibility rules reflect a balance between universality and sustainability. On one hand, the NHS embodies the principle that healthcare is a right, not a privilege. On the other, it cannot afford to be an unlimited global service.

• For residents: Entitlement flows from taxation and National Insurance.

• For expats and students: The Immigration Health Surcharge ensures a fair contribution.

• For tourists: Emergency care is guaranteed, but non-urgent treatment must be funded privately.

This layered system allows the NHS to maintain its founding promise while protecting public finances.

Common Misconceptions About NHS Eligibility

• “The NHS is free for everyone in the UK.”
  Not quite: only those ordinarily resident, or who have paid the IHS, receive full entitlement.

• “Tourists can’t get NHS treatment.”
  False: they can access emergency care, but may be charged for other treatments.

• “Expats pay twice — taxes and IHS.”
  Initially true; but once settled or naturalised, expats no longer pay the surcharge.

• “Students must buy private insurance.”
  Not if they pay the IHS. NHS access is included.

What This Means for Expats and Students in 2025

For expats, the NHS represents both reassurance and adjustment. It ensures healthcare access from day one of arrival, but also requires an understanding of the GP referral system and patience with waiting times.

For students, it removes a significant financial barrier to studying abroad. Paying the IHS upfront gives them peace of mind and allows them to participate fully in UK life.

For both groups, the NHS is not just a medical service; it is a cultural introduction to Britain — a system based on solidarity, fairness, and collective responsibility.

Eligibility for NHS treatment in the UK in 2025 is not arbitrary. It is shaped by clear rules: residency, visa status, and the Immigration Health Surcharge. For citizens and settled residents, entitlement is automatic. For expats and students, it flows from their visa and surcharge payment. For tourists, it is limited to emergencies, with private insurance strongly advised.

The system may seem complex at first glance, but its guiding principle is simple: the NHS is there for those who make the UK their home, whether temporarily as students, for work as expats, or permanently as citizens.

In an age of global mobility, this clarity is vital. It reassures newcomers that they will not face bills at the bedside, while also protecting the service for those who rely on it daily. Above all, it ensures that the NHS continues to embody its founding ethos — healthcare as a collective good, available to all who belong to Britain’s communities.
