Income protection (IP) insurance replaces a portion of earned income if the insured is unable to work due to illness or injury. Unlike a life assurance claim — which is a single event — an IP claim may last for months or years and involves ongoing medical assessment, benefit reviews, and complex interactions with other income sources.
For internationally mobile professionals, the claims process has additional considerations: evidence must be sourced from healthcare systems in other countries, currency differences arise, and the definition of incapacity must be understood in the context of an overseas career.
Before the Claim: During the Deferred Period
The deferred period (also called the waiting period or excess period) is the period between the onset of disability and the date the policy begins to pay. Common deferred periods are 1, 3, 6, or 12 months. The insured receives no benefit during this period.
A common mistake is to wait until the deferred period has expired before contacting the insurer. This is incorrect and potentially costly. You should notify your insurer at or before the point you know a claim is likely to arise — ideally within the first few weeks of becoming unable to work. Early notification:
- Alerts the insurer and begins their internal clock for assessment.
- Gives you guidance on exactly which medical evidence will be required.
- Prevents delays in the payment starting date once the deferred period expires.
- Allows the insurer to confirm the benefit quantum based on your declared income.
Most international IP insurers have dedicated claims management teams who will guide you through the process from first notification.
Medical Evidence Required at Claim
The insurer requires medical evidence to substantiate the claim. The precise requirements vary by insurer and by condition, but the standard documentation includes:
- GP report: a statement from the insured's treating GP confirming the diagnosis, the date of onset, the functional limitations imposed by the condition, and the treating physician's prognosis.
- Specialist letters and hospital records: referral letters, consultant reports, hospital admission notes, test results (bloods, scans, biopsies), and treatment records.
- Evidence of inability to work: the insurer is assessing whether you meet the policy's definition of incapacity — not merely whether you are unwell. Evidence should specifically address the work tasks you are unable to perform and why.
For internationally mobile claimants, medical records may be in a language other than English. Certified translations will be required. The insurer will typically advise which languages they can process directly and which require translation.
The Insurer's Medical Assessment
The insurer's medical adviser will review the submitted evidence against the policy's incapacity definition. There are two primary definitions in use:
Own occupation: you are incapacitated if you are unable to perform the material duties of your specific occupation. This is the more favourable and more expensive definition. An international finance director who cannot perform cognitively demanding work qualifies even if they could theoretically do a manual job.
Any occupation (suited occupation): you are incapacitated if you are unable to perform any occupation for which you are reasonably suited by education, training, or experience. This is a harder test to meet and is typically found in group schemes or lower-cost policies.
The definition that applies to your policy is specified in the contract documents — verify this before making a claim, and before taking out the policy.
For large or long-running claims, the insurer may commission an independent medical examination (IME). A specialist is appointed by the insurer to examine the claimant independently and provide an assessment of incapacity and prognosis. The insurer covers the cost; the insured must cooperate.
How the Monthly Benefit Is Calculated
The monthly benefit is not necessarily the full amount stated in the policy. Most IP policies apply an offset mechanism to prevent the total income received during incapacity from exceeding a specified percentage of pre-disability earnings (typically 60–70%).
The offset takes into account:
- State incapacity or disability benefits received.
- Employer sick pay (statutory and contractual).
- Benefits from any other IP policies in force.
- In some policy wordings, investment income above a defined threshold.
At the outset of a claim, the insurer will ask for details of all income sources. These are offset against the pre-disability income to calculate the net benefit payable. If circumstances change during the claim — for example, employer sick pay expires after six months — the benefit may adjust upward accordingly.
Pre-disability income is typically calculated using the insured's average earnings over the 12 months immediately before the onset of disability, based on payslips, tax returns, or business accounts. For the self-employed, see our guide to protection insurance for self-employed expats for detail on how variable income is treated.
Return to Work: Proportionate and Partial Benefit
Many IP claims do not conclude with a return to full-time work in the original role. Instead, the insured may return part-time, in a different or less demanding role, or at a lower salary. International IP policies typically accommodate this through proportionate or partial benefit provisions.
Under a proportionate benefit, if the insured returns to work but earns less than their pre-disability income — due to reduced hours, a different role, or ongoing medical limitations — the policy pays a proportion of the full monthly benefit to partially replace the lost income.
Example: pre-disability income £8,000 per month. Policy maximum benefit £5,600 per month (70%). Insured returns to work part-time, earning £4,000 per month. Proportionate benefit pays the shortfall up to the policy maximum, so the insured receives an additional £1,600 per month from the policy.
Most policies also provide rehabilitation support — either financial contributions toward occupational therapy, retraining, or workplace adaptations — to facilitate return to work. Engaging with this support is not merely optional; for some policies, failing to engage with reasonable rehabilitation assistance can affect the ongoing claim.
Fluctuating and Chronic Conditions
Some conditions — multiple sclerosis, Crohn's disease, chronic fatigue, certain mental health conditions — are characterised by variable severity over time. An insured may be significantly impaired during a flare and relatively functional in remission.
IP policies handle this through recurring disability provisions. If an incapacity recurs within a defined period (typically 6–12 months) of the insured returning to work, the new period of incapacity is treated as a continuation of the original claim rather than a new claim. This means the deferred period is not restarted — benefit resumes promptly.
If the recurrence occurs outside the recurring disability window, it is treated as a new claim, requiring a new deferred period to be served. Understanding the recurring disability provision in your policy is important for chronic condition management.
Annual Reviews and Ongoing Claims
For long-running claims, the insurer will conduct annual (or more frequent) reviews of the claim. The review requires:
- Updated medical evidence confirming ongoing incapacity.
- Income declarations (to ensure the offset remains correctly calculated).
- In some cases, a further IME.
The insurer may conclude at any review that the insured has recovered sufficiently to return to work, and seek to end the benefit. If you disagree with this assessment, you should challenge it immediately through the insurer's internal review process, supported by current medical evidence from your treating physicians.
Disputing a Claim Decision
The dispute routes for an IP claim are equivalent to those for a critical illness or life claim. The insurer's internal complaints process is the starting point, followed by the relevant ombudsman (IoM or UK FOS depending on the regulatory jurisdiction of the policy) and ultimately legal action as a last resort.
IP disputes are often more complex than life or CI disputes because the question of incapacity is more subjective and more fact-specific than a death or a diagnosis. Independent medical evidence and specialist legal advice are both valuable in a contested ongoing claim.

Frequently Asked Questions
When should I notify my income protection insurer — before or after the deferred period expires?
Notify your insurer during the deferred period, not after it expires. Early notification allows the insurer to guide you on evidence requirements and begin their assessment so payment is not delayed once the deferred period has elapsed.
How is the monthly benefit calculated if I have other sources of income while claiming?
Most IP policies apply an offset — they reduce the monthly benefit by the amount you receive from other income sources (state incapacity benefit, employer sick pay, other IP policies) to prevent the total income in incapacity from exceeding the policy maximum (typically 60–70% of pre-disability income).
What happens if I recover partially and return to work part-time?
Most income protection policies include proportionate or partial benefit provisions. If you return to work in a reduced capacity and earn less than your pre-disability income, the policy pays a proportionate benefit to make up a portion of the shortfall, subject to the policy's maximum benefit level.
Can my insurer stop my IP claim if my condition fluctuates?
Not necessarily. Many chronic conditions involve good and bad periods. A well-worded IP policy should continue to pay during periods when the condition is disabling, even if there are intermittent periods of partial capacity. The policy wording on recurring disability is the key factor — check whether a recurring condition restarts the deferred period or continues the existing claim.
Does an international IP policy cover me if I become unable to work in a new country after moving?
This depends on the policy's portability provisions and the definition of the covered territory. Most international IP policies from IoM-based providers are portable. You should notify your insurer of a change in country of residence and confirm that cover continues on the same terms.
