Private medical insurance (PMI) pays for eligible medical treatment in private hospitals and clinics, giving policyholders control over the timing of their care, choice of consultant, and access to facilities outside the National Health Service in the UK or public health systems elsewhere.

PMI is distinct from critical illness cover (which pays a lump sum on diagnosis of specific conditions) and income protection (which replaces earnings during illness). PMI covers the cost of treatment itself — consultations, diagnostics, surgery, hospital stays, and in many cases cancer treatment.

This guide covers UK PMI, international private medical insurance (IPMI) for expatriates, the key terms to understand before buying, and a framework for comparing the leading insurers in each market. It is intended for UK-resident and internationally mobile professionals and their families.

This is general information only. Policy terms, coverage, exclusions, and premiums vary significantly between insurers and by individual circumstance. You should take qualified advice before purchasing PMI.

PMI versus NHS: When It's Worth the Cost

For UK residents, the NHS provides free-at-point-of-use care including emergency treatment, cancer care, and specialist consultations. PMI is an elective expenditure, not a necessity for most acute conditions. The case for PMI rests on several specific factors:

Waiting times: NHS waiting times for elective procedures, specialist consultations, and diagnostics have extended significantly in recent years. The standard target is an 18-week referral-to-treatment time; many patients wait longer, particularly for non-urgent orthopaedic, ophthalmological, and dermatological procedures. PMI allows treatment to be arranged within days rather than months.

Choice of consultant: private patients can select their treating consultant. NHS patients are generally allocated to a treating team.

Hospital facilities: private hospitals typically offer single en-suite rooms, flexible visiting hours, and lower infection rates due to lower occupancy.

Diagnostic speed: private MRI, CT, and ultrasound appointments are typically available within days. NHS diagnostic waits can extend for weeks.

Mental health access: waiting times for NHS talking therapies and psychiatric consultations are particularly long in many areas. Good PMI policies include meaningful mental health cover.

What PMI does not cover: emergency treatment (the NHS handles this, usually without delay), general practice (GP appointments are not covered by most UK PMI), long-term chronic conditions managed by your GP, fertility treatment (usually excluded or limited), and pre-existing conditions under most underwriting approaches.

The cost of PMI for a healthy individual in their 30s starts at approximately £50-100 per month for basic cover; for comprehensive cover including full cancer treatment, it is often £150-250 per month or more. Premiums increase significantly with age. Whether the cost is justified depends on how you value your time and health, and whether you have specific conditions or family history that makes rapid diagnostic access important.

Types of UK PMI Cover

Core and Comprehensive Policies

Most UK insurers offer tiered products:

Core/budget cover: outpatient diagnostics and consultations, inpatient treatment, day-case procedures. Cancer cover may be limited (e.g. diagnosis only, with NHS routing for treatment). Mental health may be excluded or limited.

Mid-range cover: adds mental health, physiotherapy, dental and optical (as optional extras), and broader outpatient cover.

Comprehensive cover: full outpatient (unlimited consultations, therapies, diagnostics), full cancer cover (see below), mental health up to a meaningful annual limit, and a wider range of complementary therapies.

Hospital Lists

Most policies operate on hospital list tiers — your premium depends on which list you access. A London-only list that includes the Harley Street clinics and major central London private hospitals will cost significantly more than a list that covers regional private hospitals. Insurers frequently re-tier hospitals on their lists, which can affect your choice of facility at renewal.

Underwriting Approaches: Moratorium vs Full Medical

This is one of the most important decisions when arranging PMI.

Full Medical Underwriting (FMU)

Under FMU, you disclose your full medical history at the outset. The insurer reviews your history and confirms which conditions and treatments are covered, which are excluded, and any loadings applied to your premium. You receive certainty about your cover position before you need it.

FMU is preferable if you are in broadly good health and have a clear medical history. You know exactly where you stand from day one.

Moratorium Underwriting

Under moratorium underwriting, you do not disclose your medical history at application. Instead, pre-existing conditions are automatically excluded for the first two years of the policy (the moratorium period). After two continuous years without symptoms, treatment, or advice for a condition, it comes back into cover.

Moratorium is quicker to arrange and involves less paperwork. However, it creates uncertainty: you may not know at the point of claim whether a condition is covered or not, and disputes about what constitutes a "related" condition can arise.

Moratorium is often used by people switching insurers and wanting to avoid a lengthy underwriting process. It is less suitable for people with significant medical history who want certainty.

Continued Personal Medical Exclusions (CPME)

When switching between PMI providers, a CPME arrangement carries across the same exclusions you had on your previous policy. This avoids reimposing a moratorium period and is preferable for clients who have had long-standing cover and want continuity.

Cancer Cover

Cancer treatment is expensive and often extends over years. How a PMI policy handles cancer is one of the most important coverage questions.

Full cancer cover: covers all cancer-related treatment — surgery, chemotherapy, radiotherapy, targeted therapies, immunotherapy, cancer drugs, and palliative care — without a monetary or time limit (subject to clinical appropriateness).

Limited cancer cover: may cover diagnosis and initial treatment up to a monetary limit, with the insurer routing the patient to the NHS for ongoing treatment once the limit is reached. This can leave patients mid-treatment needing to transition between private and NHS care.

For clients to whom comprehensive cancer coverage is important, full cancer cover from a well-capitalised insurer with a good claims record is worth the additional premium.

Key questions to ask about cancer cover:

Are all NICE-approved cancer drugs covered, including those not yet available on the NHS?
Is palliative care covered?
Is there a monetary limit on cancer treatment?
Are follow-up appointments and remission monitoring covered?

Mental Health Cover

Mental health cover was historically excluded or severely limited on UK PMI policies. Standards have improved in recent years, partly as a result of regulatory and public pressure for parity with physical health.

Good policies now include inpatient psychiatric care, outpatient psychiatric consultations, psychological therapies (CBT, EMDR), and digital mental health support. Scrutinise the annual session limits and monetary caps — policies vary widely.

International Private Medical Insurance (IPMI) for Expatriates

For individuals living or working outside their home country, domestic PMI is typically inadequate or unavailable. IPMI policies are designed for international mobility and cover treatment globally (or within defined regions), regardless of where the policyholder is resident.

Key differences between IPMI and domestic PMI:

Geographic scope: IPMI covers treatment in multiple countries. Most policies exclude the USA as standard (or include it at significantly higher premium) due to the cost of American healthcare.
Portability: IPMI travels with the policyholder. If you move country, the policy typically continues without re-underwriting (subject to geographic zone changes).
Benefits design: IPMI often includes cover categories less relevant in the UK — medical evacuation and repatriation, routine maternity, dental, and optical as standard extras.
Premium basis: premiums for IPMI are typically higher than equivalent domestic cover, particularly for older policyholders.

Leading IPMI Providers (as at 2026)

The international PMI market is dominated by a small number of large insurers:

Bupa Global: one of the largest IPMI providers, strong network particularly in Europe and Middle East. Known for responsive claims handling and broad hospital networks.

AXA Health (international): comprehensive international plans with strong global network. Offers flexible modular cover design.

Cigna Global: particularly strong in Asia Pacific and Americas. Good digital tools and established corporate relationships.

Allianz Care (formerly Allianz Worldwide Care): strong for complex international assignments, including specialist care. Good reputation for medical evacuation.

April International: specialist IPMI insurer with strong presence in Europe, particularly France and Spain. Competitive for European expats.

This is not an exhaustive list, and the right insurer for any individual depends on their location, medical history, budget, and cover requirements. Insurers' products and pricing change regularly; independent comparison is essential.

Maternity Cover

Maternity is excluded by most UK PMI policies (or requires a significant waiting period, typically 10-12 months, before claims are eligible). International PMI policies have more varied approaches — some include routine maternity as a standard benefit or optional extra.

Key questions for maternity cover:

Is routine maternity covered or only complications?
What is the waiting period before maternity claims are eligible?
Is newborn care covered from birth?
What are the monetary limits per pregnancy?
Are pre-natal consultations included?

Clients planning a family should review their PMI position — and any waiting period requirements — well in advance of conception.

Dental and Optical

UK PMI policies typically offer dental and optical as optional add-ons at additional premium. International PMI policies more commonly include them. Coverage levels vary — routine check-ups, hygienist appointments, and eyecare are more commonly covered than major restorative dental work.

Premiums, Renewals, and No-Claims Discounts

PMI premiums increase with age, and insurers also apply annual claims experience factors. Good claims years may attract a no-claims discount; large claims may cause premiums to increase significantly at renewal.

Points to consider:

No-claims discount: can reduce premiums materially, but claims years reset the discount.
Switch timing: switching insurer after a claims-free period can access better rates, but any moratorium will reimpose waiting periods on conditions treated during the previous policy.
Claims year: some policies run on a calendar year, others on a rolling 12 months from inception. Understand when your claims year resets.

Common Exclusions

Standard exclusions across most PMI policies include:

Emergency treatment (routed to NHS or local public system)
General practice consultations
Pre-existing conditions (under moratorium underwriting, for the moratorium period)
Infertility treatment (often excluded or strictly limited)
Cosmetic or aesthetic treatment
Self-inflicted injury
Treatment arising from hazardous activities (varies by policy)
Experimental treatments not clinically proven
