Does Critical Illness Cover Actually Pay Out?

What the published figures show

The Association of British Insurers and Group Risk Development publish annual protection-claims data, but they do not break the headline payout rate down by product. For 2025:

• Across individual life insurance, income protection and critical illness combined, 97.9% of individual protection claims were paid.
• Across individual and group protection together, insurers paid £7.84 billion, around £21.5 million a day.

The ABI reports that this combined figure has stayed at or above 97.9% for more than a decade. There is no separately published UK figure for critical illness claims alone, so the 97.9% combined figure is the most relevant published evidence, not a critical-illness-specific number. See does life insurance actually pay out? for the equivalent figure published specifically for life insurance (96.7%).

What those figures do not tell you

• They are not critical-illness-specific. The 97.9% figure spans life insurance, income protection and critical illness together, so it says nothing about how critical illness claims perform on their own compared with the other two products.
• They are industry averages. Different insurers and products can have different claims experience.
• They describe claims that were made. A policy that ended without a claim does not appear as a declined claim.
• They do not override the policy wording. Whether a particular claim is payable depends on the policy terms, the diagnosis and the facts of the claim.

The careful conclusion is therefore that declined claims are a minority across protection products generally, not that a critical illness claim in particular is guaranteed to be paid.

Why a critical illness claim might not be paid

There is no single reason. The exact position depends on the policy and the circumstances.

The condition doesn't meet the policy's definition

Critical illness policies define each covered condition in detail, often by reference to a required level of severity. Critical illness cover explained sets out how these definitions work. A diagnosis that a person and their doctor would describe as serious may still not meet the specific wording the policy uses, particularly for conditions with graded or partial-payment definitions.

The condition isn't on the list the policy covers

Every policy lists the conditions it covers. A serious illness that isn't on that list, or that falls outside how the list is worded, isn't covered by that policy, however serious it is in practice.

Policy lapsed or inaccurate application info

Cover can end if required premiums are not paid, so a diagnosis after the policy has lapsed would not be covered. Separately, when taking out cover, applicants answer questions about matters such as health and family medical history. If an insurer later believes an answer was inaccurate or incomplete, it may consider whether the policy or claim should be changed, reduced or declined. The Financial Ombudsman Service explains that these disputes are considered under the law on consumer insurance misrepresentation.

If a question is unclear when applying, asking the insurer, broker or adviser for clarification is safer than guessing what the question means.

What is worth checking in a policy

These are factual checks rather than recommendations about whether to buy cover. Critical illness cover explained sets out the terms these checks refer to:

• which conditions are covered, and how the main ones are defined;
• whether any conditions only qualify for a partial payment;
• whether there is a survival period, and how long it is;
• whether premiums must continue throughout the term;
• who knows that the policy exists and where the documents are kept.

If a claim is declined

The insurer should explain its decision. A complaint can first be made to the insurer. If the complaint is not resolved satisfactorily, the Financial Ombudsman Service may be able to consider it, subject to its normal complaint rules and time limits.

Questions worth considering

• Which conditions does the policy cover, and how are the main ones defined?
• Does any condition only qualify for a partial payment?
• Is there a survival period, and how long is it?
• Were the application questions answered accurately and completely?
• Would the people who may need to make a claim know where the policy documents are?
