Insurance Underwriting for Expats: Medical and Non-Medical Limits

Underwriting is the process by which an insurer assesses the risk presented by a prospective policyholder and decides whether to offer cover, at what premium, and with what exclusions. For an expatriate seeking life assurance, critical illness, or income protection cover, the underwriting process is shaped by the same core factors as for a domestic client — age, health history, sum assured, and occupation — but with additional layers of complexity arising from country of residence, travel patterns, and international healthcare history.

This guide explains how underwriting works for internationally mobile clients and what the key thresholds and processes are.

The Underwriting Basis

Life and protection insurance underwriting can be conducted on two main bases:

Full Medical Underwriting (FMU)

The applicant discloses full details of their health history on the application form. The insurer assesses this information and may request additional evidence (GP report, specialist reports, blood tests, ECG, or medical examination). Coverage is granted on the basis of all known information; any pre-existing conditions that are disclosed may be excluded from coverage or attract a premium loading.

Advantage for the policyholder: The policy's terms are known at outset. There is no ambiguity about whether a condition is covered or excluded — it has been assessed.

Disadvantage: The application process is more detailed and may take longer. Some conditions will be excluded or rated; the applicant must decide whether the resulting policy meets their needs.

Moratorium Underwriting (CPME: Continued Personal Medical Exclusions)

No health questions are asked at application. Instead, the policy automatically excludes any condition for which the policyholder received medical advice, treatment, or medication during a defined "moratorium period" (typically the five years before the policy start date). After a further defined period of no advice, treatment, or symptoms, those conditions may become eligible for cover.

Advantage: Simpler and faster to apply. Suitable for group schemes with large numbers of employees.

Disadvantage: The extent of exclusion is not known at outset and may only become clear when a claim is made. For an internationally mobile client who has received medical care in multiple countries in multiple languages, identifying what falls within the moratorium period can be complex.

For individually underwritten international life and protection policies, full medical underwriting is standard. Moratorium underwriting is more common in group income protection and group critical illness schemes.

Non-Medical Limits

Non-medical limits (NMLs) are sum assured thresholds below which a life or critical illness policy can be issued without requiring additional medical evidence beyond the standard application form health questionnaire. Above the NML, the insurer requires medical evidence before it can offer terms.

NMLs vary by:

• Insurer
• Product type (life, critical illness, income protection)
• Age of the applicant
• Total existing cover (including policies already in force)

As of 2026, typical NMLs for international life assurance providers for a 40-year-old applicant might be in the range of £1–3 million for sum assured without a medical examination (though exact figures vary by provider and are subject to change). At older ages, NMLs are generally lower.

When a client applies for an amount above the NML, the insurer will request one or more of:

• Non-medical evidence: Blood tests (full blood count, cholesterol, liver function, kidney function, HIV/Hepatitis B/C, glucose)
• Blood pressure and urinalysis: Simple measurements often conducted at the medical examination
• Resting ECG: Standard for older applicants and larger sums
• Stress ECG: For very large sums or where cardiac risk factors are present
• Full medical examination: Conducted by an insurer-approved doctor
• Specific investigations: Where the health questionnaire reveals risk factors

For internationally mobile clients, the insurer will typically need to arrange the medical examination in the country where the applicant is resident. Most major international providers have access to medical examiner networks in key expatriate locations (Dubai, Singapore, Hong Kong, major European cities, etc.).

Additional Underwriting Factors for Expatriates

Beyond the standard health and financial assessment, internationally mobile clients face underwriting factors that domestic clients do not:

Country of Residence

The insurer assesses the country where the applicant currently lives. Certain countries attract underwriting ratings or restrictions because:

• Healthcare infrastructure: Where medical facilities are limited, diagnosis and ongoing management of conditions may be less reliable. This creates uncertainty for the insurer about the reliability of the health declaration and the management of any ongoing conditions.
• Political and conflict risk: Some insurers will not provide cover, or will exclude war and civil unrest, for applicants resident in certain high-risk countries.
• Disease prevalence: Countries with higher prevalence of certain conditions (malaria, tuberculosis, specific cancers with dietary or environmental correlates) may be rated accordingly.
• Life expectancy data: Where reliable mortality statistics are limited, the insurer must use external data sources or apply a country-of-residence loading.

Most international providers maintain an internal list of acceptable and restricted countries. Clients should be aware that moving to a restricted country during the policy term should be reported to the insurer; failure to do so may affect cover.

Occupation for Expatriates

Many expatriates work in sectors that attract occupational ratings:

Hazardous occupations in international settings:

• Oil and gas extraction (offshore or onshore in high-risk regions)
• Construction supervision in developing markets
• Security, military contracting, or protective services
• Mining and extraction
• Aid and development work in conflict-affected areas

Professional occupations with location risk:

• Medical professionals in high-exposure environments
• Journalists in conflict zones
• Government or diplomatic staff in high-risk postings

Occupational ratings may take the form of:

• A premium loading (percentage addition to the standard rate)
• An exclusion for death or disability arising from a specific occupation-related risk (e.g., war exclusion)
• A refusal of cover for particularly high-risk roles

Disclosure of the full nature of the occupation — not just the job title — is essential. An "international consultant" working in a stable European capital is a very different risk from an "international consultant" advising clients in an active conflict zone.

Foreign Travel

Even if the primary country of residence is low-risk, extensive travel to high-risk countries is a relevant underwriting factor. Insurers typically ask about:

• Countries visited in the past year and planned in the next year
• Frequency and purpose of travel to those countries
• Whether travel is for business (and if so, the nature of the work)

Occasional business travel to high-risk countries as part of a professional role (e.g., a management consultant visiting a client site in a conflict-affected region) is typically accommodated, sometimes with a loading. Frequent or prolonged stays in such countries create more significant underwriting concerns.

Currency and Country of Payment

Some international providers ask about the currency in which premiums will be paid and the country from which payments originate. Anti-money laundering requirements may require the insurer to conduct source-of-funds checks for larger premium amounts.

Aggregation: Totalling All Cover

When a client applies for a new policy, all existing policies with the same or other insurers must be disclosed. Insurers aggregate the total sum at risk before deciding whether additional medical evidence is required.

For an internationally mobile client who holds a domestic UK policy, a group death-in-service benefit through their employer, and is now applying for an additional international policy, the total sum at risk includes all three amounts. If the aggregate exceeds the non-medical limit for the new policy, medical evidence will be required even if the new sum assured alone is below the threshold.

Failure to disclose existing cover is a material non-disclosure and can affect claim validity.

Financial Underwriting

For large sums assured, the insurer will also conduct financial underwriting — assessing whether the proposed sum assured is proportionate to the policyholder's financial interest. The basis:

• Personal policies: Typically a multiple of earned income (the insurer will not insure for more than a client could reasonably justify on a financial need basis)
• Key person policies: Assessed against the financial loss the business would suffer
• Loan protection: Assessed against the outstanding loan amount

For high-net-worth internationally mobile clients applying for significant sums, the financial justification must be documented and credible. An international provider may request evidence of income, assets, or business financial statements.

Underwriting Outcomes

The possible outcomes of an underwriting assessment are:

1. Standard terms: Cover offered at the standard premium, no exclusions
2. Rated terms: Cover offered with a premium loading to reflect elevated risk
3. Exclusion: Cover offered but with a specific condition or risk excluded
4. Rated and excluded: Both a loading and an exclusion applied
5. Postponed: Cover cannot be offered at present (e.g., pending investigation of a recent health issue, or while in a temporary high-risk environment)
6. Declined: The risk is outside the insurer's acceptable parameters and no offer is made

For expatriates who receive a decline or significant loading from one insurer, it is worth approaching specialist international brokers who have access to the full range of international providers. Underwriting standards and appetite vary between providers, and a risk that is unacceptable to one may be acceptable to another.
