United Kingdom – Health Insurance

Is health insurance mandatory for expats in the UK?

There is no legal obligation for expats living or working in the United Kingdom to hold private health insurance. That said, most people arriving on a visa valid for longer than six months are legally required to pay the Immigration Health Surcharge (IHS) as part of their visa application process. The IHS is a fee that certain migrants must contribute when applying for UK immigration permission to reside in the country beyond a short-term stay. It is not technically a form of insurance — rather, it is a mandatory payment that unlocks entitlement to NHS healthcare.

The vast majority of foreign nationals seeking temporary permission to live in the UK must pay the IHS on top of the standard visa application fee. Those applying under work, family, and student visa categories are typically required to settle the surcharge in full when lodging their visa application or extension request. Certain exemptions exist — for instance, European nationals who were already living in the UK before 31 December 2020 and are applying for Pre-Settled or Settled status are not obliged to pay the NHS Surcharge. Irish nationals do not need to apply for a UK visa at all and enjoy full entitlement to NHS treatment.

Private health insurance remains entirely a matter of personal choice, even after the IHS has been paid. Nevertheless, many expats opt for private medical insurance (PMI) to sidestep NHS waiting lists and gain access to a wider spectrum of care. Those who arrive on a short-stay visa of six months or fewer and have not paid the IHS will generally be billed for any NHS treatment they receive. Without prior insurance arrangements, non-eligible visitors face charges of 150% of the standard NHS rate. No criminal sanctions apply for the absence of private health insurance, but uninsured visitors who are ineligible for free treatment can accumulate considerable medical costs.

Failing to settle outstanding NHS charges may jeopardise future UK visa applications. Always verify the IHS obligations associated with your specific visa category on the official UK government website before submitting your application.

How does the public health system in the UK work?

The National Health Service (NHS) sits at the core of UK healthcare — a government-operated, not-for-profit system that provides medical treatment to all those who qualify. Financed through general taxation, it ensures that the cost of care does not stand between patients and treatment. This distinguishes it from France’s social insurance model (where employees contribute to the Assurance Maladie and receive reimbursements) or Germany’s statutory health insurance (Gesetzliche Krankenversicherung); unlike those systems, the NHS draws almost entirely on tax revenues and National Insurance contributions, with no ongoing premium payments for most users.

Within the NHS, GPs serve as the first point of contact and gatekeepers to specialist and hospital services. There is no need to weigh up which provider covers a particular treatment — so long as care falls within the NHS and you are eligible, it is available to you anywhere in England. This referral-based model means that, in contrast to some European systems where patients may approach specialists directly, you must first be assessed and referred by your GP. Expats who are used to booking specialist appointments without such a referral step may need time to adjust to this approach.

Although the NHS operates as a national service, healthcare policy is managed separately in Scotland, Wales, and Northern Ireland. The overarching principle of ordinary residence applies across all four nations, but specific rules differ: Scotland and Wales have abolished prescription charges, and Northern Ireland likewise provides free prescriptions, placing additional emphasis on community-based health access. In England, prescription charges remain (£9.90 per item in 2025), though numerous groups — including children, older people, and those with certain chronic conditions — qualify for exemptions.

Eligibility for NHS treatment without charge is based on the concept of “ordinary residence.” This status is not determined by nationality, whether you pay UK taxes or National Insurance, whether you are registered with a GP, whether you hold an NHS number, or whether you own property in the UK. Being ordinarily resident means living in the UK on a lawful and settled basis for the foreseeable future, and you will be expected to demonstrate this.

The standard of NHS care is broadly high by international comparison; however, a prolonged period of constrained funding growth has left the service grappling with staffing shortfalls, bed pressures, and ageing equipment. The UK’s position in the World Health Care Index has declined steadily over recent years. As a result, patients can face lengthy waits for non-urgent procedures, and the quality of provision can differ noticeably from one region to another.

How do expats register for public health coverage in the UK?

Signing up for NHS care begins at a local GP surgery and is a relatively uncomplicated process. Once registered, you will be allocated an NHS number, which serves as your unique identifier across all NHS services in England. You can search for GP practices near your home using the NHS Find a GP service. It is always worth checking current requirements at NHS.uk before registering, since procedures may differ slightly across the devolved nations.

1. Check your eligibility. Establish that your visa category and intended length of stay make you eligible for NHS care. If your visa covers more than six months and you have paid the IHS, you are entitled to NHS treatment from the date your visa is granted.
2. Find a local GP surgery. You are free to select the GP practice of your choice, though some practices only accept patients who live within a defined catchment area, so you will need to pick one that is reasonably close to your home address.
3. Contact the GP surgery. Telephone or visit the surgery to confirm it is taking on new patients and to ask about the registration process. A growing number of GP practices now offer online registration through the NHS App or their own practice website.
4. Complete the registration forms. You will be required to fill in a GMS1 registration form or an equivalent. At your first appointment you will typically receive a brief health check and be asked to complete the necessary paperwork. A confirmation letter will follow in the post, and your medical records will be transferred to that practice.
5. Provide supporting documents. Bring your passport, your visa or Biometric Residence Permit (BRP), and evidence of your UK address such as a tenancy agreement or a utility bill. You do not need to supply separate proof that you have paid the IHS — this is automatically linked to your visa record.
6. Receive your NHS number. Your NHS number is issued once you have registered with a GP and acts as confirmation of your eligibility for NHS services throughout the UK. You will need it for all future interactions with NHS services.
7. Register dependants separately. If your spouse, civil partner, or children have accompanied you to the UK, they are entitled to free NHS hospital treatment provided they hold their own visas as dependants. Each dependant is required to pay the Immigration Health Surcharge individually and must register with a GP to access the full range of NHS services.

Registration itself is generally quick once you have identified a surgery that is accepting new patients. There is no separate enrolment with a central health insurance authority — registering with a GP automatically connects you to the broader NHS system.

What costs are involved in the public health system in the UK?

Unlike the social insurance contribution models used in France, Germany, or the Netherlands, the NHS does not charge expats ongoing monthly premiums based on income. Instead, access is funded through the Immigration Health Surcharge, which generally amounts to £1,035 per year and is due when each applicant submits their UK visa application. The full surcharge for the entire duration of your intended stay must be paid upfront before you travel to the UK. This means that, for example, a three-year Skilled Worker visa would require a single upfront IHS payment of £3,105 for the main applicant.

The charge is calculated in six-month increments and must account for your entire period of stay. If your permitted stay is 15 months, you will be charged for 18 months. A reduced rate of £776 per year applies to students. Where an application covers a period that includes part of a year in excess of six months, you will be billed for a further half-year. These figures were established as of February 2024 and should be confirmed using the official UK government IHS calculator, as rates may be updated.

Beyond the IHS, everyday NHS use carries some additional costs. In England, patients are expected to contribute to certain aspects of their care, such as prescription and dental charges, and the same applies to expats. NHS prescription charges in England stand at £9.90 per item as of June 2025, following an increase on 1 May 2024. Prescriptions remain free of charge in Scotland, Wales, and Northern Ireland.

NHS dental treatment is organised into bands, with costs ranging from around £26 for a basic examination to approximately £306 for more complex procedures. Eye tests and corrective lenses are not routinely funded by the NHS for most adults. It is also worth noting that paying the IHS does not accelerate your access to treatment — clinicians will assess the urgency of your condition in the same way as for any other ordinarily resident patient, and if necessary you will be placed on the appropriate waiting list.

What does public health cover in the UK include and exclude?

The NHS ranks among the most comprehensive publicly funded health systems in the world. Its coverage spans a wide range of services, from emergency care and GP consultations to specialist referrals, inpatient hospital treatment, and maternity services. Mental health provision, treatment for infectious diseases, oncology, and palliative care are all included within the NHS offer. While most hospital-based services are provided without direct charge to eligible patients, a number of specific services or treatments delivered in NHS hospitals are exempt from charges regardless of eligibility, including accident and emergency attendance, family planning services, treatment for most notifiable infectious diseases, and care required for a physical or mental condition resulting from violence.

Certain services fall outside standard NHS coverage. These include prescription charges in England, dental treatment, sight tests, and some forms of cosmetic surgery. Travel vaccinations required for overseas trips and certain specialist treatments may also involve an out-of-pocket cost. Access to fertility treatment and IVF varies significantly depending on location — some NHS Integrated Care Boards provide a limited number of funded IVF cycles, while others offer no funding at all. Elective cosmetic procedures undertaken purely for aesthetic reasons are entirely excluded.

Dental access warrants particular attention. While NHS dental services do exist, waiting lists can be exceptionally long, and a great many dental practices have stopped accepting NHS patients. Numerous reports have highlighted that millions of people across the UK are unable to secure an NHS dental appointment, leaving them either on lengthy waiting lists or compelled to seek private treatment. For newly arrived expats, locating an NHS dentist willing to take on new patients can prove to be one of the more challenging practical aspects of settling in the UK.

Waiting times are a significant factor in the NHS experience. As of mid-2024, the median waiting time for consultant-led elective care exceeded 14 weeks, and hundreds of thousands of patients were waiting more than a year for certain procedures. Emergency care, by contrast, is rapid — dialling 999 in a genuine emergency will bring an ambulance and priority treatment regardless of a patient’s residency status or IHS payment. For non-urgent treatment, waits of up to 18 weeks are a recognised feature of the current system.

What are the advantages of international private health insurance for expats in the UK?

Even though NHS entitlement provides broad, no-cost-at-point-of-use coverage for qualifying expats, many choose to complement it with private medical insurance (PMI). The principal motivation is speed of access. Despite the NHS’s wide reach, there are compelling reasons to consider a private health insurance policy. PMI enables you to skip NHS waiting lists for specialist consultations, diagnostic imaging such as MRI and CT scans, and planned surgical procedures.

Private insurance also puts you in greater control of your healthcare journey. You can typically select your own consultant or surgeon and opt for a hospital that suits your location and preferences. The UK has a substantial private healthcare sector, with more than 200 registered private hospitals and clinics spread across the country, with particular concentrations in London, Manchester, and Birmingham. The advantages of private healthcare include significantly shorter waiting times, a more personalised approach to treatment, and access to more advanced medical technologies and procedures.

International Private Medical Insurance (IPMI) — which is distinct from a standard domestic UK PMI policy — is purpose-built for individuals living outside their country of origin. IPMI plans typically offer global or regional coverage, letting you select a policy that covers you worldwide or worldwide with expensive markets such as the USA excluded in order to reduce premiums. Medical evacuation is a particularly valuable benefit: should local facilities be unable to provide adequate care, IPMI can fund transport to the nearest centre of medical excellence. Crucially, IPMI coverage travels with you as you relocate between countries. These plans frequently include benefits that domestic UK PMI does not, such as routine dental care, preventive health checks, and in some cases maternity coverage.

Private cover can also address gaps that exist within NHS provision. Many policies extend to services such as mental health support, physiotherapy, and dental and optical care — all areas where timely NHS access can be difficult to secure. For expats who have only recently arrived and have not yet established a relationship with a local GP, private insurance can offer a quicker initial route into care, including access to remote or telehealth consultations.

How do international private health insurance plans work in the UK?

Private health insurance in the UK operates in parallel with the NHS rather than as a replacement for it. It is essential to understand that PMI is intended to complement NHS care, not substitute for it. Its primary function is to offer an alternative pathway for acute treatment, allowing policyholders to bypass NHS waiting lists for non-emergency procedures. In practice, most people with private cover continue to rely on the NHS for GP consultations, emergency care, and the long-term management of chronic conditions.

A variety of plan structures are available in the UK market, each offering different levels of coverage and benefits: individual plans, tailored to the healthcare needs of a single person; family plans, which bring all members of a household under a single policy; and group plans, frequently offered by employers as part of a staff benefits package. Both domestic UK insurers — such as Bupa, AXA Health, and Aviva — and internationally focused providers — including AXA Global Healthcare, Cigna, and Allianz Care — operate in this space.

When assessing policies, expats should pay close attention to several key areas. Inpatient cover — encompassing hospital admission and surgical procedures — is included in virtually all policies. Outpatient cover — which extends to specialist appointments, diagnostic investigations, and physiotherapy that do not require an overnight stay — is often sold as an optional add-on. Outpatient cover is a particularly important enhancement. It funds diagnostic testing and specialist consultations that do not necessitate hospitalisation. Without it, you would be reliant on the NHS during the initial investigation and diagnosis phase. Policyholders can frequently choose a benefit limit, for example £500, £1,000, or an unlimited amount.

Pre-existing conditions represent a crucial element to examine carefully. The manner in which insurers approach pre-existing and chronic health conditions is a fundamental principle of PMI globally, and the UK market is no different. Policies are typically underwritten on one of two bases: moratorium underwriting, under which pre-existing conditions are automatically excluded for an initial period and may subsequently become eligible for cover if you remain symptom-free; or full medical underwriting (FMU), where you disclose your complete medical history at the outset and receive a clear schedule of exclusions from the start of the policy. Age is the most significant single factor in premium pricing, with costs rising substantially as policyholders get older. Geography also plays a role: premiums in London and the South East tend to be higher due to the elevated cost of hospital care in those areas.

Standard PMI exclusions typically include routine maternity care, cosmetic surgery undertaken for aesthetic rather than medical reasons, and treatment for drug or alcohol dependency. Dental and optical care are not generally part of core policies, though they can commonly be added as optional extras. Always verify that any insurer you are considering is authorised and regulated by the Financial Conduct Authority (FCA), the body responsible for overseeing insurance providers in the UK.

What should expats watch out for with health insurance in the UK?

One of the most important misunderstandings to avoid is treating the IHS payment as equivalent to comprehensive health cover. While paying the IHS secures your right to use the NHS, it does not entitle you to faster treatment. For many expats — particularly those on time-bound work placements or those travelling with families — waiting several months for care may simply not be feasible. Grasping this distinction clearly before you arrive will help you determine whether supplementary private cover is the right choice for your situation.

It is also important to understand that the IHS must be paid even if you already hold private health insurance. The surcharge remains a mandatory component of the visa application regardless of any private medical cover you have arranged. This means that many visa holders are effectively paying twice — once through the IHS and again through private insurance premiums. Some expats conclude that this dual expenditure is worthwhile for the reassurance and speed that private care provides; others decide to rely solely on the NHS.

Waiting periods attached to private policies catch many new policyholders off guard. Among the most commonly misunderstood features of any private medical insurance policy is the “waiting period” — the interval between the policy start date and the point at which you can make a claim for certain benefits. Many people who are eager to use their new cover are taken aback to discover that not all services are immediately accessible. Dental add-ons in particular often impose waiting periods of three to six months before routine treatment is covered, with even longer delays for major procedures such as orthodontic work.

Travel insurance is a fundamentally different product from health insurance. Travel policies are designed to cover emergency situations during short trips abroad, not ongoing healthcare for someone living as a resident in the UK. If you are planning a long-term stay in the UK, relying on a travel policy taken out in your home country will leave you without adequate protection, and you should not use one as a substitute for anything beyond brief visits. Similarly, the European Health Insurance Card (EHIC) issued by EU member states is valid only for medically necessary care during temporary stays — it is not an alternative to health cover for UK residents.

Finally, expats returning to the UK after a period spent living abroad should be mindful of a potential gap in NHS eligibility. While most returning permanent residents are typically reassessed as “ordinarily resident” relatively quickly, it is sensible to arrange a short-term private policy to bridge any administrative delay between your arrival and the restoration of your NHS entitlement. Always consult NHS.uk and the NHS entitlements migrant health guide on GOV.UK for the most up-to-date eligibility information before you travel.

Frequently asked questions about health insurance in the UK

Can I use my home country’s health insurance in the UK?

In the vast majority of cases, no. Health insurance policies taken out in your home country are not generally recognised for ongoing healthcare purposes in the UK. If you hold an EHIC issued by an EU or EEA country, it may cover treatment that becomes medically necessary during a temporary visit, but it is not a substitute for resident health cover. Once you are living in the UK on a long-term basis, you will need either to pay the IHS as part of your visa in order to access the NHS, or to arrange a private or international health insurance policy that is valid in the UK.

Do I need private health insurance if I have a UK work visa?

For expats arriving under work, family, or study visas, the Immigration Health Surcharge (IHS) is what unlocks NHS entitlement, at a cost of £1,035 per adult per year as of 2025. Once the surcharge has been paid, you have full access to the NHS and private insurance is not a requirement. Even so, a significant number of working expats choose to supplement NHS access with private PMI in order to reduce waiting times, particularly for specialist appointments and diagnostic investigations.

Is the NHS really free for expats who pay the Immigration Health Surcharge?

GP visits and NHS hospital treatment are free of charge once the IHS has been paid, but a number of specific services do involve fees. Having settled the surcharge, visa holders access the NHS on the same footing as ordinary residents. They can register with a GP, receive inpatient hospital care, and make use of emergency services without further charges beyond the standard prescription and dental fees. In England, each prescription item costs £9.90 as of 2025, and NHS dental treatment is structured into tiered charge bands, though many patient groups are exempt from these costs.

How long does it take to register with an NHS GP as an expat?

There is no standard processing time — it varies according to the GP surgery and the level of local demand. Some practices are able to register new patients within a matter of days, while others maintain waiting lists. To secure an appointment you will need to contact the surgery directly to check availability. It may take a few weeks to be seen for a routine appointment, but if your need is urgent you can be placed on a triage pathway. It is advisable to register with a GP as soon as you arrive, even if you are in good health at the time.

What happens if I need NHS treatment before I have registered with a GP?

Emergency treatment is accessible regardless of whether you are registered with a GP. NHS emergency care is provided free of charge whatever your residential status. Any individual requiring NHS services — including accident and emergency attendance, family planning, treatment for an infectious disease, or care for a physical or mental condition arising from violence — may access these without charge. For non-emergency care before you have completed your GP registration, NHS 111 (available by phone or online) can provide urgent clinical advice and direct you to the most appropriate service.

Are pre-existing conditions covered by NHS treatment?

Yes — the NHS does not apply exclusions for pre-existing conditions. Provided you are eligible as an ordinarily resident person or as an IHS-paying visa holder, you will receive treatment for any medical condition regardless of your history. This represents a meaningful advantage compared with private health insurance, where pre-existing conditions are frequently excluded, at least for an initial period. That said, NHS waiting times for the ongoing management of long-term and chronic conditions can be considerable.

Is dental care included in NHS cover for expats?

Some NHS dental services are accessible in principle, but waiting lists are often very long and a large proportion of dental practices have stopped accepting NHS patients altogether. Those practices that do take NHS patients will generally request your NHS number and may contact your GP to confirm the treatment you are entitled to. Many expats find that securing an NHS dental appointment is genuinely difficult, and end up registering with a private dentist or adding a dental cover option to their insurance policy. Routine eye tests are not funded by the NHS for most adults.

Should I get international expat health insurance or a local UK private medical insurance policy?

The right answer depends on your personal circumstances. A domestic UK PMI policy typically costs less and is well suited to expats who intend to stay in the UK for the long term. An International Private Medical Insurance (IPMI) plan is designed for individuals living and working abroad — these policies are considerably more comprehensive and travel with you between countries. If you frequently relocate or want coverage that remains valid wherever you are in the world, an IPMI plan is usually the stronger option. If you are settled in the UK and primarily want to complement your NHS access, a domestic PMI policy will generally represent better value for money.
