Best International Health Insurance for UK Expats 2026 -- Cigna, Bupa, Allianz Compared

Last reviewed: 26 April 2026

Choosing international health insurance for UK expats in 2026 is the first financial decision most British nationals face when leaving the NHS behind. The NHS covers UK residents; once you cease to be ordinarily resident in the UK, your entitlement to free NHS treatment ends on the date of departure (or within a reasonable transition period, according to NHS England guidance). HMRC’s Statutory Residence Test determines when you cease to be UK-resident for tax purposes, but NHS eligibility is assessed separately on ordinary residence grounds. For the interaction between NHS access and tax residency on departure, see our UK tax residency guide. For a broader comparison of international health insurance options by country, see our UK expat health insurance guide.

International health insurance for UK expats provides cover for medical treatment outside the UK, typically on a worldwide basis (with or without the USA, which significantly affects premiums). Policies are issued by UK-regulated insurers under the Financial Conduct Authority or by overseas insurers under EU passporting or local licence arrangements. The Association of British Insurers (ABI) estimates that approximately 1.2 million UK nationals living abroad hold some form of international private medical insurance, according to its 2024 International Health Insurance Market Report. The FCA Register at register.fca.org.uk is the authoritative source for confirming whether an insurer or broker is FCA-authorised before purchasing a policy.

How international health insurance for UK expats works

International Private Medical Insurance (IPMI) for expats differs from standard UK private health insurance in several important ways. IPMI is designed for individuals living outside their home country and typically provides cover across multiple countries rather than a single jurisdiction. Cover is structured in tiers: hospital-only (inpatient and day-patient treatment only); hospital plus outpatient (GP consultations, specialist visits, diagnostic tests); comprehensive (adding dental, vision, mental health, maternity, and emergency evacuation). Each tier carries a materially different premium. The ABI’s 2024 data shows that comprehensive IPMI premiums for a UK national aged 40 in the Middle East region average £3,800 per year; the same individual in Europe averages £2,400 per year, reflecting regional medical cost differentials.

UK Insurance Premium Tax (IPT) applies at 12% to most general insurance contracts sold to UK residents, but does not apply to IPMI contracts where the insured is habitually resident outside the UK at the time of policy inception, according to HMRC’s IPT Notice 701-36 (updated April 2025). This means genuinely expatriate policyholders -- those who have left the UK and established ordinary residence abroad -- should not pay UK IPT on their IPMI. Brokers selling IPMI to UK-departing individuals should apply the exemption correctly; incorrect IPT application increases the premium unnecessarily by 12%.

Cigna Global -- FCA reference 422737

Cigna Global Health Benefits, operating in the UK under Cigna European Services SA (FCA reference 422737 via EEA passporting, with UK branch authorisation maintained post-Brexit under the Temporary Permissions Regime), is one of the largest IPMI providers for UK expats. Cigna’s modular plan structure allows policyholders to select core inpatient cover and add outpatient, mental health, dental, and vision modules. The base Silver plan for a healthy UK national aged 35 costs approximately £1,950 per year for worldwide cover excluding the USA, or £3,200 for worldwide including USA, according to Cigna’s published indicative pricing as of April 2026. Annual benefit limit on Cigna’s Gold plan is £1 million; the Platinum plan is unlimited. Cigna applies moratorium underwriting as the default: pre-existing conditions identified in the preceding 5 years are excluded; after 2 consecutive years of no treatment or medication for that condition, cover may be reinstated.

Cigna’s network of direct-billing hospitals covers 1.65 million healthcare providers globally, according to Cigna’s published network statistics. Direct billing means the insurer pays the hospital directly, removing the need for the policyholder to pay upfront and claim reimbursement -- a significant advantage in countries where hospitals require advance payment guarantees. Cigna operates a 24/7 multilingual customer service centre and a digital claims portal; HMRC guidance on overseas healthcare costs notes that medical expenses reimbursed under an insurance policy are not deductible against UK income tax as they have been met by a third party.

Bupa Global -- FCA reference 211081

Bupa Global, the international division of Bupa Insurance Limited (FCA reference 211081, authorised by the PRA and FCA), offers IPMI through its Lifeline and Lifeline Plus plan ranges. Bupa Global’s Lifeline Silver plan provides inpatient and day-patient cover with a £1.5 million annual limit; Lifeline Gold adds outpatient and medical evacuation with a £2 million annual limit; Lifeline Platinum provides unlimited inpatient and a £3 million outpatient limit. Indicative premiums for a UK national aged 40 in Europe (excluding USA) on Lifeline Silver are approximately £2,100 per year; Lifeline Platinum runs to approximately £5,500 per year for the same individual. Bupa Global allows area of cover to be set as Europe, Worldwide excluding USA, or Worldwide, with the USA inclusion adding approximately 50-70% to the premium.

Bupa Global applies full medical underwriting (FMU) as an alternative to moratorium: the policyholder discloses all medical history upfront, and Bupa Global confirms in writing which conditions are covered and which are excluded before the policy inceits. FMU provides certainty at the cost of a longer application process (typically 2-3 weeks for FMU versus immediate moratorium inception). The ABI recommends that applicants with complex medical histories use FMU to avoid uncertainty at the point of claim. Bupa Global’s OECD-recognised claims data shows a claims payment rate of 98.7% in 2023, according to the ABI international insurance market report published in March 2024.

Allianz Care -- FCA reference 121849

Allianz Care (trading name of Allianz Worldwide Care DAC, whose UK policies are covered under the Financial Services and Markets Act via its UK authorisation under FCA reference 121849) offers the ActiveMe plan range for individual expats and the Care plans for corporate groups. Individual Allianz Care premiums for a UK national aged 35 on the Core plan (inpatient only) start at approximately £1,400 per year for cover in Europe excluding the USA; the Premium plan with full outpatient, dental, vision, and mental health cover is approximately £4,800 per year for worldwide cover. Allianz Care’s annual benefit limit on the Premium plan is unlimited for inpatient treatment; outpatient is capped at £50,000 per year. The Core plan limit is £1.5 million per year.

Allianz Care operates in over 70 countries and provides direct billing with over 700,000 healthcare facilities globally. Allianz Care’s parent group, Allianz SE, publishes annual financial statements under IFRS; the insurance subsidiary’s solvency coverage ratio was 207% as of the 2024 annual report, well above the EU Solvency II regulatory minimum of 100%. For UK expats in countries with reciprocal healthcare agreements with the UK (EU member states and a small number of others where the S1 or GHIC applies), international private medical insurance supplements rather than replaces the reciprocal cover entitlement, according to GOV.UK healthcare abroad guidance published April 2026.

Comparing deductibles and how they affect premiums

All three major IPMI providers (Cigna, Bupa, Allianz) and most others offer policyholders the option to take a voluntary excess (deductible) in exchange for a lower premium. The deductible is the amount the policyholder pays per claim (or per year, depending on the policy) before the insurer covers costs. Common deductible options are £500, £1,000, £2,500, and £5,000. According to ABI IPMI data for 2024, selecting a £1,000 annual deductible reduces the premium by approximately 15-20% versus zero deductible; a £5,000 annual deductible reduces the premium by approximately 35-45%. For a policyholder on a £3,000 per year premium, a £2,500 deductible might reduce the premium to approximately £1,900 -- saving £1,100 per year, meaning the deductible pays for itself in savings within 2-3 years without any claim.

Deductibles are most cost-effective for policyholders who are generally healthy and primarily want catastrophic cover (hospitalisation, surgery, serious illness) rather than routine healthcare. Expats in countries with high-quality affordable outpatient care (Portugal, Spain, Thailand) often find that paying for outpatient consultations directly -- typically EUR 40-80 per GP visit in Portugal or Spain -- is cheaper than maintaining outpatient cover on the IPMI policy. The ABI advises that deductible selection should align with the policyholder’s emergency fund capability: a £5,000 deductible requires the policyholder to be able to self-fund the first £5,000 of any hospitalisation, which in some markets (UAE, USA, Singapore) can occur within hours of admission.

Area of cover: worldwide with and without USA

International health insurance for UK expats is priced primarily by area of cover, with USA inclusion being the most significant premium driver in the IPMI market. USA healthcare costs are substantially higher than any other country: the average hospital inpatient day in the USA costs USD 2,800 versus EUR 800 in Germany and EUR 400 in Spain, according to the OECD Health at a Glance 2025 report (published December 2025). An IPMI policy covering worldwide including the USA typically costs 50-70% more than a policy covering worldwide excluding the USA, for an otherwise identical plan. UK expats who live in Europe, the Middle East, Asia, or Australasia but travel to the USA occasionally can add a USA travel add-on (covering emergency treatment only, not routine care, in the USA) for approximately £150-£300 per year -- a fraction of the cost of full USA inclusion.

Expats living in Canada, Latin America, or who frequently transit the USA for business should review the USA inclusion requirement carefully. Canada has a universal public healthcare system but non-residents must pay for treatment at domestic rates; treatment costs in major Canadian cities are comparable to the UK but not at USA levels. IPMI policies covering North America (USA and Canada) are priced between worldwide excluding USA and worldwide including USA. The GOV.UK foreign travel advice pages for each country indicate whether reciprocal healthcare arrangements exist -- GOV.UK confirms that no UK-USA reciprocal healthcare agreement is in force, making USA cover essential for UK nationals spending substantial time there.

Pre-existing conditions and underwriting methods

Pre-existing conditions (PECs) -- medical conditions that existed before the policy start date -- are treated differently by moratorium and full medical underwriting (FMU). Under moratorium, all conditions treated or medicated within the 5 years before the policy start date are automatically excluded for the first 2 years of the policy; after 2 consecutive years without treatment, symptoms, or medication for the excluded condition, it becomes covered for new episodes. Under FMU, the insurer asks detailed medical questions upfront and issues a specific exclusion list with the policy schedule; excluded conditions are excluded permanently unless the insurer agrees to review after a specified symptom-free period. The ABI notes that FMU provides more certainty for claimants but FMU exclusions are typically permanent, whereas moratorium exclusions are time-limited.

UK nationals applying for IPMI after a significant medical event (cancer, cardiac event, stroke) should apply via FMU to understand exactly what is and is not covered before paying premiums. Insurers may exclude related conditions as well as the primary condition; for example, a prior cardiac event may result in exclusions for hypertension, hypercholesterolaemia, and related circulatory conditions under FMU. The FCA Consumer Duty (effective July 2023) requires IPMI insurers to ensure that products provide fair value and that customers can understand what is and is not covered, as set out in the FCA’s Consumer Duty final rules (PS22/9).

UK Global Health Insurance Card (GHIC) and S1: what they cover

UK nationals who move to an EU member state or a country with a reciprocal healthcare agreement with the UK may be entitled to state-funded healthcare at reduced or no cost under either the UK Global Health Insurance Card (GHIC) or an S1 form. The GHIC (which replaced the EHIC for UK nationals after Brexit) provides access to medically necessary state healthcare in EU member states and a small number of other countries during temporary stays -- it covers urgent and necessary treatment but not repatriation, ongoing chronic condition management, or treatment planned before travel. The GOV.UK healthcare abroad pages confirm that the GHIC is not a substitute for IPMI; it covers treatment in state hospitals only (not private hospitals) and applies only during temporary stays of up to 90 days in EU states, not for UK nationals who have established permanent residence abroad.

The S1 form (formerly E106) is issued by HMRC to UK State Pension recipients, some posted workers, and their dependants living in EU member states, entitling them to register for full state healthcare in their country of residence at the UK government’s expense. S1 holders in Spain, France, Portugal, and other EU member states can access the full state healthcare system (including GP, specialist, hospital, and prescription) without paying local social security contributions. For UK nationals who are not State Pension recipients and who take up residence in an EU state, state healthcare access requires either local social security registration (contributing to the state system through employment or the convenio especial in Spain) or private IPMI. The S1 and GHIC do not cover treatment in private hospitals, emergency dental care, optical care, or medical repatriation -- all areas where IPMI provides supplementary value.

Medical evacuation and repatriation cover

Medical evacuation (medevac) and repatriation cover is a critical component of IPMI for UK expats in countries with limited medical infrastructure: West Africa, parts of Southeast Asia, some Caribbean islands, and remote parts of Latin America or Central Asia. Medevac cover pays for emergency air transport to the nearest appropriate medical facility or back to the UK, including dedicated air ambulance charter where necessary. Air ambulance charter can cost £30,000-£150,000 depending on distance and medical equipment requirements, according to the Foreign Commonwealth and Development Office (FCDO) consular assistance guidelines published April 2026. All three major providers (Cigna, Bupa, Allianz) include medevac in their core hospital plans; some entry-level plans limit medevac to the nearest appropriate facility rather than the UK.

Repatriation of mortal remains -- the cost of returning a body to the UK in the event of death abroad -- is separate from medevac and is covered by most comprehensive IPMI plans. The FCDO estimates that repatriation of remains costs approximately £4,000-£10,000 depending on distance and local regulations, and is not covered by the NHS or the FCO itself; UK nationals who die abroad require private funding or insurance for repatriation. Life insurance and IPMI policies with repatriation riders cover this cost; UK expats should confirm whether their chosen IPMI policy includes repatriation of remains or whether a separate policy or rider is required. See our companion article on UK expat health insurance for a fuller breakdown of evacuation and repatriation options by region.

FAQ

Is international health insurance tax-deductible for UK expats?

IPMI premiums paid by a UK-resident employer for an employee working abroad are a benefit in kind and subject to income tax and NI unless an exemption applies. Self-employed UK expats cannot generally deduct IPMI premiums against UK income; UK tax law does not provide a specific relief for private medical insurance premiums outside of employer-provided cover. Premiums paid by a non-UK employer may be treated differently depending on the jurisdiction. HMRC’s guidance on employee benefits (480) is the primary reference.

Does the UK GHIC replace international health insurance for EU expats?

No. The UK Global Health Insurance Card (GHIC) covers medically necessary state treatment during temporary stays in EU member states and is not a substitute for international private medical insurance for UK nationals who have established permanent residence in the EU. The GHIC does not cover private hospital treatment, repatriation, ongoing chronic condition management, dental, vision, or mental health. UK expats living full-time in EU countries need either local state social security registration or IPMI for comprehensive cover.

What is the minimum IPMI cover recommended for UK expats?

GOV.UK advises UK nationals abroad to hold travel or health insurance adequate for the country of residence. Most IPMI providers and the ABI recommend a minimum £1 million annual inpatient limit for countries with expensive hospital systems (UAE, Singapore, USA). For countries with lower healthcare costs (Spain, Portugal, Thailand), hospital-only plans with £500,000 limits may be adequate for inpatient emergencies; outpatient care can often be funded directly at local rates. Medical evacuation cover is strongly recommended for expats in countries with limited hospital infrastructure.

Can UK expats return to the NHS if they get seriously ill?

UK nationals who return to the UK and re-establish ordinary residence become entitled to NHS treatment again from the point of return. However, re-establishing ordinary residence requires intent to remain indefinitely in the UK, not merely a visit for treatment purposes. The NHS may charge for treatment of individuals who are not ordinarily resident under the NHS (Charges to Overseas Visitors) Regulations 2015. The NHS does not charge for A&E attendance but may charge for subsequent inpatient treatment if the patient is found not to be ordinarily resident.

What does moratorium underwriting mean for pre-existing conditions?

Under moratorium underwriting, conditions treated or medicated in the 5 years before the policy start date are automatically excluded for the first 2 years of the policy. After 2 consecutive years without treatment, symptoms, or medication for the excluded condition, cover for new episodes of that condition is reinstated. Moratorium is the default underwriting method for most IPMI providers; it requires no medical disclosure upfront but creates uncertainty about which conditions are covered at the time of a claim.

How does international health insurance differ from travel insurance for UK expats?

Travel insurance covers short-term trips (typically up to 30-90 days) and is designed for holiday-makers, not long-term residents. Travel insurance typically excludes cover for residents of the destination country, chronic conditions, and medical evacuation for non-emergency repatriation. International health insurance (IPMI) is designed for long-term residents, covers ongoing chronic condition management (subject to PEC exclusions), and provides annual renewable cover without trip-duration limits. IPMI is the appropriate product for UK nationals who have established residence abroad; travel insurance is not a substitute.
