United Kingdom – Health Risks, Inoculations, Vaccinations, and Health Certificates

What are the main health risks for expats living in the United Kingdom?

As a high-income country, the United Kingdom benefits from excellent sanitation infrastructure, safe drinking water, and a well-established public health system. For the vast majority of people relocating there, everyday health risks are broadly comparable to those in any other Western European nation. That said, a number of infectious disease trends have emerged in recent years that are worth understanding before you make your move.

Measles staged a significant comeback, with 362 laboratory-confirmed cases recorded in England in 2023, followed by a dramatic surge to 2,911 cases in 2024. Pertussis (whooping cough) also climbed sharply over the same period, with laboratory-confirmed cases jumping from 856 in 2023 to a provisional 14,905 in 2024. These outbreaks are partly attributed to the disruption that the COVID-19 pandemic caused to routine childhood immunisation programmes, making it all the more important to verify that your own vaccinations are fully current.

Tuberculosis cases rose by 11% in 2023 relative to 2022, and provisional figures pointed to a further 13% increase in 2024 — a trend that could put the UK’s low-incidence classification with the World Health Organization at risk. TB remains more concentrated in urban areas and continues to be a public health priority for the UK Health Security Agency (UKHSA).

England recorded the highest number of gonorrhoea diagnoses since records were first kept in 1918, along with the highest syphilis case numbers since 1948. Sexually transmitted infections therefore represent a genuine concern, though routine sexual health screening is freely and widely available through the NHS.

Norovirus activity arrived earlier than usual in autumn 2024, and weekly surveillance data from February 2025 indicated the highest levels recorded since current reporting methods were introduced in 2014. As the virus spreads readily in communal and public environments, maintaining thorough hand hygiene throughout the year remains an important precaution.

Malaria is not present in the UK except in cases contracted overseas. There is no local transmission of dengue, Zika virus, or other tropical diseases. Rabies does not circulate among wild or domestic animals, though certain bat species may carry a related virus. Food safety and environmental health standards are high, and tap water is safe to drink across the entire country.

Locally acquired tick-borne encephalitis (TBE) cases have been documented in parts of England and Scotland; however, vaccination is not currently recommended as a routine measure for UK residents, and the primary advice centres on tick bite prevention. Anyone planning to spend considerable time in rural or wooded settings should wear long-sleeved clothing and use appropriate insect repellent as sensible precautions.

Are any vaccinations or inoculations required before entering the United Kingdom?

There are no mandatory vaccinations required to enter the United Kingdom. No yellow fever vaccination certificate is required for this country. Vaccinations are not required for entry. In contrast to some nations that insist on proof of yellow fever immunisation for travellers arriving from endemic regions, the UK enforces no such requirement at its borders.

Vaccine-derived poliovirus type 2 (cVDPV2) was detected in sewage samples from Leeds, London, and West Sussex during November and December 2024. All travellers should have completed a polio vaccination course in line with either the UK schedule or their own national programme, and those who are not UK residents should follow any supplementary guidance issued by their country of residence. There is no polio certificate requirement for entering or departing the UK.

It is important to draw a clear distinction between formal entry requirements and health recommendations. While no vaccinations are mandated at the border for short-term visitors, long-stay visa applicants from certain countries are subject to a separate health screening process — specifically for tuberculosis — which is covered in full in the section below.

Which vaccinations are recommended for expats moving to the United Kingdom?

Expats should confirm that primary vaccination courses and boosters are up to date as recommended for life in Britain — including, for example, the seasonal flu vaccine, COVID-19 (if eligible), MMR, and vaccines required for occupational risk of exposure, lifestyle risks, and underlying medical conditions. This is the core advice from NHS Scotland’s Fit for Travel service, and it reflects guidance from health authorities across the UK’s four nations.

In light of the pronounced increase in measles cases, the MMR (measles, mumps, and rubella) vaccine warrants particular attention. Global health authorities, including the CDC, advise that all international travellers be fully protected against measles through MMR vaccination. Anyone who cannot document two prior MMR doses from their home country should prioritise receiving them before departure or promptly upon settling in the UK.

Tetanus is another vaccine to review if your course is incomplete. A full tetanus protection programme in the UK consists of five doses over a lifetime. People arriving from countries with differing vaccination schedules may not have completed all five — it is worth confirming this with your GP or a travel health clinic ahead of your move.

Hepatitis A and Hepatitis B are selectively advised vaccines — only for those individuals at highest risk. Your personal level of risk will be shaped by your lifestyle, professional setting, and individual medical history. Those employed in healthcare, childcare, or roles involving close contact with vulnerable populations may be recommended these vaccines as a precautionary measure.

It is also worth noting that the UK’s national childhood immunisation schedule differs in some respects from those used in other countries. Certain vaccines that are routinely administered elsewhere — such as standalone varicella (chickenpox) immunisation — do not feature in the standard UK schedule, while others, including the Men B and Men C (meningococcal) vaccines, are offered to infants and young people. Parents relocating with children should discuss the UK schedule with a GP or paediatrician when registering.

Health professionals generally recommend consulting a travel health clinic or GP four to six weeks before departure. This timeframe allows sufficient opportunity to complete any multi-dose vaccine courses and to receive tailored advice based on your personal health history and intended location within the UK.

Do you need a health certificate to move to or work in the United Kingdom?

For the majority of visa categories, there is no requirement to undergo a general medical examination or obtain a health certificate in order to move to the UK. However, one significant health-related requirement does apply to many long-stay visa applicants: a tuberculosis (TB) test.

A TB test is required if a UK visa applicant is coming to the UK for more than six months and they have been continuously present in a relevant country for six months or more, including a period of any length within the six months before the date of application. The relevant countries are listed in TB6 of the Appendix Tuberculosis to the Immigration Rules. This list includes many nations across Africa, Asia, Latin America, and parts of Eastern Europe — you should check the official gov.uk TB test page to confirm whether your country of residence appears on it.

Not only must applicants be tested for tuberculosis, but the test needs to be undertaken by an approved medical clinic. The test typically involves a chest X-ray, but in addition or in limited circumstances, a sputum sample can be provided.

Here is the step-by-step process for completing the TB requirement:

1. Check if you need a TB test — Visit gov.uk/tb-test-visa and confirm whether your country of residence is on the list of relevant countries requiring screening.
2. Find an approved clinic — A list of approved clinics where visa applicants can get tested for TB is published by the UK government. Only results from these clinics are accepted; results from non-approved facilities will not be valid for your visa application.
3. Attend your appointment — A UK visa applicant will usually undergo a chest X-ray to test for TB. A sputum test is required only if the chest X-ray is inconclusive.
4. Receive your certificate — After successfully obtaining a negative test result, you will be issued a tuberculosis clearance certificate, which you will need to include as part of your visa application.
5. Submit within the validity window — An applicant applying for a UK visa must show the certificate was issued within the six-month period immediately before the date of application. It is important to note that a TB test certificate is only valid for six months from the date it is issued.
6. Account for children — Children still need to provide a TB test certificate, but they will not necessarily need to undergo a chest X-ray; instead, a child must see a clinician who will assess whether a chest X-ray is necessary.

The cost of TB testing varies by country and approved clinic. Fees are determined by individual clinics rather than set by the UK government, so you should contact your nearest approved clinic directly for current pricing information. As of 2025, consult the official gov.uk page for the most current list of approved clinics and any associated fee guidance.

Beyond TB screening, most visa applicants intending to stay in the UK for more than six months are also required to pay the Immigration Health Surcharge (IHS). Most people need to pay the IHS as part of their online immigration application, whether they need to pay depends on the immigration status they are applying for, and they can start using the NHS free of charge from the date their visa starts. The IHS rate is subject to periodic revision — always verify the current figure at gov.uk/healthcare-immigration-application before submitting your application.

How does healthcare in the United Kingdom compare to what expats may be used to?

The UK is home to one of the world’s most well-known publicly funded healthcare systems: the National Health Service (NHS). Rather than relying principally on private insurance or direct out-of-pocket payment, the NHS draws its funding from general taxation and delivers most healthcare services at no charge at the point of use to those who qualify. Expats who have paid the Immigration Health Surcharge as part of their visa application gain NHS access from the moment their visa takes effect.

Primary care within the NHS revolves around General Practitioners (GPs). Registering with a local GP practice is among the first and most consequential steps to take after arriving in the UK. Your GP serves as your main port of call for everyday health concerns and is responsible for referring you to specialist services when necessary. Much like the gatekeeper model in use in countries such as the Netherlands or Canada, accessing hospital specialists typically requires a GP referral rather than direct self-booking.

The standard of NHS care is generally high, and the UK is home to internationally regarded hospitals, research institutions, and specialist treatment centres. That said, waiting times for non-urgent specialist consultations and elective procedures can be considerably longer than expats from systems with greater private sector capacity may be accustomed to. A substantial private healthcare sector operates alongside the NHS, with private hospitals and clinics offering quicker consultant appointments and elective procedures — albeit at considerable expense. Many expats choose to take out private health insurance to complement their NHS entitlements, particularly where faster specialist access is a priority.

Medical professionals throughout the UK work in English, and internationally trained doctors make up a significant proportion of the NHS workforce. In major cities such as London, Manchester, Edinburgh, and Birmingham, patients from diverse linguistic and cultural backgrounds are commonplace, and clinical staff often bring a correspondingly broad range of experience. In more rural areas, English remains the primary working language, though NHS interpretation services are available to patients who require support in another language.

Certain categories of service carry charges even for those otherwise covered by the NHS — these include prescriptions, dental treatment, eye tests, and assisted conception. In England, prescription charges are applied at a fixed rate per item, with exemptions for children, older adults, and people with specific medical conditions. Prescriptions are provided free of charge in Scotland, Wales, and Northern Ireland. NHS dental care is subsidised but not free for most adults, and securing a place with an NHS dentist accepting new patients can prove difficult in certain areas. Private dental practices are widely available as an alternative.

What are the risks of travel within the United Kingdom, and are there regional health differences?

The UK does not contain zones affected by tropical diseases, altitude-related illness, or malaria — health risks do not fluctuate dramatically from one region to the next in the way they might across a country spanning vastly different climate zones. Nevertheless, there are some meaningful variations in health environment and disease patterns across England, Scotland, Wales, and Northern Ireland that incoming expats should bear in mind.

Urban areas — particularly London and other major cities — have historically recorded higher rates of TB, HIV, and certain sexually transmitted infections. Air quality can be a genuine consideration in central London and other densely populated urban centres, where pollution concentrations — especially particulate matter and nitrogen dioxide — occasionally exceed recommended thresholds. People living with asthma, respiratory conditions, or cardiovascular disease are advised to monitor air quality forecasts, which are published by the UK Met Office and the DEFRA UK Air quality monitoring service.

Locally acquired cases of tick-borne encephalitis have been confirmed in parts of England and Scotland. Those planning to spend extended periods in rural or forested environments — including the Scottish Highlands, the Lake District, or sections of the South Downs — should take appropriate precautions against tick bites, such as wearing long-sleeved clothing and conducting thorough skin checks after time outdoors. Lyme disease, which is also tick-borne, is present in the UK and is a further consideration for those who enjoy outdoor pursuits.

Scotland, Wales, and Northern Ireland each operate devolved health services — NHS Scotland, NHS Wales, and the Health and Social Care service in Northern Ireland respectively. While the founding principle of care that is free at the point of use applies across all four nations, there are notable policy differences between them — prescription charging arrangements and certain screening programmes, for instance, vary from one nation to another. Expats settling in Scotland, Wales, or Northern Ireland should take time to understand the specific health service operating where they live.

Mental health is a significant area of concern across the UK, with demand for NHS mental health provision considerably exceeding available capacity. Waiting times for NHS talking therapies or psychiatric referrals can be substantial. Many expats find that accessing private counselling or therapy represents a practical solution, particularly during the challenging adjustment period that often accompanies a major international move. The British Association for Counselling and Psychotherapy (BACP) maintains a searchable online directory of accredited practitioners.

Frequently Asked Questions

Do I need any vaccinations before I can enter the United Kingdom?

No vaccinations are legally required to enter the UK. There is no yellow fever certificate requirement, and no compulsory immunisations are checked at the border. However, health authorities strongly recommend that all routine vaccinations — including MMR, tetanus, polio, and influenza — are up to date before you travel. If you are applying for a long-stay visa from a country with high TB rates, you will need a separate tuberculosis screening, which is a visa requirement rather than an entry vaccination requirement.

Will my home-country vaccination records be accepted in the UK?

Yes, in most cases. When you register with a GP in the UK, you can present your existing vaccination records from your home country. A GP or practice nurse can review your history and advise whether any catch-up doses are needed under the UK schedule. If your records are in a language other than English, it may be helpful to bring a translated summary. The UK does not require you to repeat vaccinations you have already received unless there is a clinical reason to do so.

Is health insurance required to live in the United Kingdom?

It is not legally required for most long-stay visa holders, because most will pay the Immigration Health Surcharge (IHS) as part of their visa application, which grants access to the NHS. However, private health insurance is a popular option among expats who want faster access to specialists or private hospital care alongside their NHS entitlements. If you are on a short-stay visa or visiting, travel insurance covering medical expenses is strongly recommended, as NHS access for short-stay visitors is limited to urgent and emergency treatment.

Do I need a TB test for my UK visa, and how long does it take?

You need a TB test if you are applying to stay in the UK for more than six months and have lived for at least six months in a country listed as having a high TB burden. The test is a chest X-ray performed at a UK government-approved clinic in your country of residence. A sputum test may also be required if the X-ray is inconclusive. The certificate issued is valid for six months from the date of the X-ray. Processing times vary by clinic — chest X-ray results are typically available quickly, but sputum tests can take up to eight weeks. Check the official list of approved clinics and required countries at gov.uk/tb-test-visa.

What happens if I develop a serious illness after moving to the UK?

If you are registered with a GP and have NHS access (either through the IHS or other eligibility), you can access NHS emergency and hospital services. In a medical emergency, call 999 for an ambulance or go to the nearest Accident and Emergency (A&E) department — emergency care is available to everyone regardless of immigration status. For urgent but non-emergency situations, NHS 111 is a free phone and online triage service available 24 hours a day. You can also attend an NHS Urgent Treatment Centre without a GP referral.

How do I find a GP (general practitioner) after I arrive in the UK?

You can find and register with a local GP practice using the NHS’s online tool at nhs.uk/service-search/find-a-gp. GP practices generally accept registrations from anyone living within their catchment area, and registration is free. You do not need to wait until you are unwell — registering as soon as you arrive means you will have a named GP and can access referrals, repeat prescriptions, and preventive health services from the outset. In some areas with high demand, finding a practice with open registration may take a little persistence.

Are medical staff in the UK likely to speak my language?

Healthcare in the UK is delivered in English, and all clinical staff are required to meet English language standards. In major cities, you are likely to find GP practices and hospital staff with a wide range of language backgrounds who can communicate informally in other languages. The NHS also provides professional interpreter and translation services for patients who need them — you can request an interpreter when booking an appointment. Organisations such as the Doctors of the World Safe Surgeries network can also help connect vulnerable or newly arrived patients with appropriate care.

Is there a risk of measles or whooping cough in the UK?

Yes — both measles and whooping cough (pertussis) have seen significant increases in England in recent years. Measles cases rose to nearly 3,000 in 2024, and whooping cough cases reached a provisional figure of nearly 15,000 for the same year. These increases are linked to lower vaccination uptake following the COVID-19 pandemic. If you or your children are not fully vaccinated with the MMR vaccine (two doses) and a full course of pertussis-containing vaccines, you should address this before or shortly after arrival. Your GP can advise on catch-up vaccination.
