Introduction
Income protection and critical illness cover are both designed to provide financial support during genuinely difficult times, but their claims processes work quite differently from a straightforward one-off payout like life insurance. Income protection pays an ongoing income replacement based on your continued inability to work, which means claims can be reassessed over time, while critical illness cover pays a lump sum, but only if your diagnosis meets the precise definition set out in your specific policy. This guide walks through how each claims process actually works, what evidence you'll typically need, and what to do if a claim doesn't go the way you expected.
This is a general educational guide, not medical, legal or financial advice, and individual policy wording varies considerably between insurers. Always refer to your own policy documents and contact your insurer directly with questions about your specific claim.
Key Terms Explained
- Deferred Period
- The period between becoming unable to work and income protection payments starting, chosen when the policy was taken out.
- Own-Occupation Definition
- An income protection definition that pays out if you can't do your specific job, even if you could do a different type of work.
- Any-Occupation Definition
- An income protection definition that only pays out if you can't do any job reasonably suited to your skills, training and experience.
- Condition Definition
- The precise medical criteria a critical illness policy requires a diagnosis to meet before it qualifies as a valid claim under that specific condition.
- Terminal Illness Benefit
- A feature in many life and critical illness policies allowing an accelerated early payment following a qualifying terminal diagnosis.
- Claims Review
- A periodic reassessment of an ongoing income protection claim, typically involving updated medical evidence.
Why This Matters
Unlike a home or car insurance claim, an income protection or critical illness claim often arises during one of the most stressful periods of a person's life, a serious diagnosis or a prolonged inability to work. Understanding how the process works in advance, rather than trying to learn it for the first time while unwell, can make a genuine difference to how smoothly a claim proceeds and how confident you feel engaging with it.
Our Life Insurance Claims: How the Payout Process Works UK guide covers the one-off death claim process; this guide focuses specifically on the different mechanics involved in income protection and critical illness claims, which work in genuinely distinct ways.
Making an Income Protection Claim
Notify Your Insurer Promptly
Contact your insurer as soon as reasonably possible after becoming unable to work, rather than waiting to see how things develop. The deferred period, the time between becoming unable to work and payments starting, begins running from when you actually became incapacitated, not from when you get around to calling your insurer, so early notification matters even if you don't expect to need payments for some time.
Provide Medical Evidence
You'll typically need evidence from your GP or a relevant specialist confirming your condition and its impact on your ability to work. Insurers may request a medical report directly from your doctor, usually with your written consent, and in some cases arrange an independent medical assessment, particularly for more complex or long-running claims.
Confirm Your Occupation Definition Applies
Check whether your policy uses an own-occupation or any-occupation definition, since this materially affects what "unable to work" means for your specific claim. Own-occupation cover focuses on your specific job; any-occupation cover, generally cheaper to buy, sets a considerably higher bar, requiring that you can't do any job reasonably suited to your skills and experience, not just your usual one.
Supply Income Evidence
Since income protection replaces a portion of lost income, you'll generally need to provide evidence of your earnings, such as payslips, tax returns, or accounts if you're self-employed, so the insurer can confirm the correct benefit amount.
Making a Critical Illness Claim
Check the Specific Condition Definition
Critical illness policies list precisely defined conditions, each with specific medical criteria, rather than covering any serious illness in general terms. Two policies naming the same condition, such as a particular type of cancer or a cardiac event, can define the qualifying severity or stage differently, so checking your own policy's exact wording for the relevant condition is an essential first step.
Provide a Confirmed Diagnosis
You'll need medical evidence, typically from a consultant or specialist, confirming the diagnosis and that it meets the specific criteria set out in your policy. Insurers generally require this from appropriately qualified medical professionals rather than accepting a general summary alone.
Understand Survival Periods
Some critical illness policies include a survival period, commonly a number of days following diagnosis, that must be met before a claim is payable. Check your own policy wording for whether this applies and what the specific period is.
Submit the Claim Promptly
While critical illness claims don't have a deferred period in the way income protection does, submitting your claim promptly after diagnosis, with the required medical evidence, helps avoid unnecessary delay in what can already be a difficult time.
The Claims Process at a Glance
| Stage | Income Protection | Critical Illness Cover |
|---|---|---|
| Trigger | Ongoing inability to work due to illness or injury | Diagnosis meeting a specific, defined condition |
| Key Evidence | Medical evidence of incapacity, income evidence | Specialist diagnosis meeting exact policy criteria |
| Timing Feature | Deferred period before payments start | Possible survival period after diagnosis |
| Payment Type | Ongoing, regular income replacement | One-off lump sum |
| Reassessment | Periodic claims reviews while payments continue | Generally none, once a valid claim is paid |
Terminal Illness Benefit
Many life insurance and some critical illness policies include a terminal illness benefit, allowing an early, accelerated payment if you're diagnosed with a terminal illness and given a limited life expectancy, rather than requiring the family to wait for a death claim. The specific definition of "terminal illness" and any life-expectancy criteria vary between insurers, so checking your own policy wording, or asking your insurer directly, is important if this situation applies to you or a loved one. This feature can provide meaningful financial support during a family's most difficult period, allowing funds to be used while they matter most.
Ongoing Reviews and Rehabilitation
Because income protection pays an ongoing benefit rather than a one-off sum, insurers typically carry out periodic reviews of claims that continue for an extended period. This normally involves updated medical evidence and sometimes a conversation about your recovery and any potential for rehabilitation or a phased return to work.
This is a standard part of managing a long-term claim rather than necessarily a sign the insurer doubts your situation, and many insurers offer rehabilitation support, such as physiotherapy or vocational support, as part of managing income protection claims constructively for both sides. Engaging openly with these reviews, rather than viewing them as adversarial, generally leads to a smoother ongoing claims experience.
If Your Claim Is Declined
Ask for a Clear Explanation
Request a written explanation of exactly which policy terms or definitions weren't met, and what specific evidence the decision was based on. A clear explanation is the essential starting point for deciding whether, and how, to challenge the decision.
Provide Additional Evidence if Appropriate
If you believe the insurer's assessment missed relevant medical information, ask your medical team whether further evidence, or a more detailed report addressing the specific policy definition, could support your case.
Escalate to the Financial Ombudsman Service
If you've raised your disagreement with the insurer directly and remain unsatisfied with the outcome, our Financial Ombudsman Service and Insurance Complaints UK guide explains how to bring an independent, free complaint about a UK-regulated insurer.
Check Whether Non-Disclosure Is a Factor
If a decline relates to information given, or not given, when you applied, our Life Insurance and Mental Health UK guide explains how the ABI Code of Practice on non-disclosure applies to this kind of situation, including for income protection and critical illness cover.
Real-World Examples
Example: An Own-Occupation Income Protection Claim
A tradesperson develops a back injury preventing physical work. Because their policy uses an own-occupation definition, the claim is accepted once the deferred period has passed, even though they could potentially do desk-based work in a different role.
Example: A Critical Illness Claim Meeting the Defined Criteria
A policyholder is diagnosed with a condition specifically listed in their critical illness policy. Their consultant provides evidence confirming the diagnosis meets the exact severity criteria set out in the policy wording, and the lump sum is paid following the survival period specified in the policy.
Example: An Ongoing Income Protection Review
A claimant receiving income protection payments for over a year is asked to provide updated medical evidence as part of a routine claims review. The review confirms continued incapacity, and payments continue uninterrupted, with a discussion about a potential phased return to work in future.
Common Mistakes to Avoid
- Delaying notification of an income protection claim until near the end of the deferred period.
- Assuming any serious diagnosis automatically qualifies under a critical illness policy without checking the exact definition.
- Not confirming whether your income protection policy uses an own-occupation or any-occupation definition before you need to claim.
- Treating a routine ongoing claims review as a sign the insurer is trying to end your claim.
- Not seeking a clear written explanation when a claim is declined.
Common Myths
- Myth: Critical illness cover pays out for any serious illness. It only pays for the specific conditions listed in your policy, meeting the precise criteria defined for each one.
- Myth: Income protection reviews mean the insurer is trying to stop paying. Periodic reviews are a standard, expected part of managing a long-term claim, not evidence of bad faith.
- Myth: All income protection policies define "unable to work" the same way. Own-occupation and any-occupation definitions differ significantly, and the difference genuinely matters at claim time.
- Myth: A declined claim is always final. You can request a detailed explanation, provide further evidence, and escalate an unresolved dispute to the Financial Ombudsman Service.
Frequently Asked Questions
How do I start an income protection or critical illness claim?
Contact your insurer as soon as reasonably possible after becoming unable to work or being diagnosed, rather than waiting. Most insurers have a dedicated claims line or online process, and starting early gives more time to gather the medical evidence needed, particularly relevant to income protection's deferred period.
What evidence do I need for an income protection or critical illness claim?
You'll typically need medical evidence from your GP or specialist confirming your diagnosis or incapacity, details of any treatment, and for income protection, evidence of your income and occupation. Insurers may also request a medical report directly from your doctor with your consent, and in some cases arrange an independent medical assessment.
What is a deferred period and how does it affect an income protection claim?
The deferred period is the length of time between becoming unable to work and payments starting, chosen when you took out the policy. You need to be unable to work for the full deferred period before benefit payments begin, so notifying your insurer promptly, rather than waiting until the deferred period has almost passed, is important.
What's the difference between own-occupation and any-occupation income protection?
Own-occupation cover pays out if you can't do your specific job, even if you could do a different type of work. Any-occupation cover, which is generally cheaper, only pays out if you can't do any job reasonably suited to your skills and experience, which is a considerably higher bar to meet at claim time.
How does critical illness cover define which conditions qualify?
Critical illness policies list specific defined conditions and set out precise criteria that must be met, such as a particular diagnosis, stage or severity, rather than covering any serious illness in general terms. It's important to read your specific policy definitions, since criteria can vary meaningfully between insurers even for the same named condition.
Can I claim critical illness cover for a terminal diagnosis?
Many life insurance and critical illness policies include a terminal illness benefit, allowing an early payment if you're diagnosed with a terminal illness and given a limited life expectancy, subject to the specific policy's definition and any relevant time-to-live criteria. Check your own policy wording, since this feature and its exact terms vary.
What happens if my income protection claim is ongoing for a long time?
Insurers typically carry out periodic reviews of ongoing income protection claims, which may involve updated medical evidence, and in some cases a review of whether rehabilitation or a phased return to work is appropriate. This is a normal part of managing a long-term claim, not necessarily a sign the insurer doubts your claim.
Why might an income protection or critical illness claim be declined?
Common reasons include the condition not meeting the policy's specific definition or severity criteria, insufficient medical evidence, the condition falling under a policy exclusion, or non-disclosure discovered during the claims assessment. Understanding your policy's exact definitions before claiming can help you and your medical team provide the most relevant evidence.
What can I do if my claim is declined and I disagree?
Ask the insurer for a clear written explanation of the decision and which specific policy terms weren't met. If you still disagree after raising this with the insurer directly, you can escalate a genuine dispute to the Financial Ombudsman Service, which independently reviews complaints about UK-regulated insurers.
Does non-disclosure at application affect income protection or critical illness claims?
Yes. If an insurer discovers relevant health information wasn't accurately disclosed when you applied, this can be assessed under the ABI Code of Practice on non-disclosure, which can affect the claim outcome depending on whether the non-disclosure was deliberate, careless, or a genuine misunderstanding.

Conclusion
Income protection and critical illness claims work quite differently from a one-off life insurance payout, and understanding those differences before you need to claim genuinely helps. Income protection depends on your specific occupation definition and the deferred period, with ongoing claims subject to periodic review, while critical illness cover pays against precisely defined conditions rather than general severity. In both cases, prompt notification, thorough medical evidence, and understanding your own policy's exact wording give you the best chance of a smooth, successful claim.
If a claim doesn't go the way you expected, a clear explanation, further evidence where appropriate, and, where necessary, an independent complaint to the Financial Ombudsman Service are all legitimate next steps.
