Critical illness cover has an image problem. People assume insurers look for reasons to decline a claim. The 2025 data says the opposite.
More than 89% of individual critical illness claims were paid in 2025, and most insurers paid over 90% of the claims they received, according to ABI figures. Yet only 23% of people surveyed correctly guessed that the majority of claims are paid. Most assume the true figure is far lower. Insurers paid £1.25 billion in individual critical illness claims in 2025 alone, with an average payout of £67,000. Payouts have exceeded £1 billion every year for five consecutive years. Cancer accounts for almost two-thirds of all critical illness claims (65%), up 3% year on year. This is not a policy for rare events. It mostly pays out for the illness that touches nearly every extended family in the country.
| Product | Trigger for payout | Payment type | What it does not do |
|---|---|---|---|
| Critical illness cover | Diagnosis of a specified serious illness (cancer, heart attack, stroke, MS, and others, as defined by the ABI Minimum Standards). | Tax-free lump sum | Does not pay for illnesses outside the defined list and does not replace lost income beyond the lump sum |
| Income protection | Inability to work due to illness or injury (usually any illness or injury, rather than a fixed list). | Repayment mortgages | Regular monthly income, often paid until you return to work or reach retirement. |
| Life insurance | Death within the policy term | Tax-free lump sum | Pays nothing while you are alive, however serious the illness. |
| Combined life and CIC | Either death or diagnosis of a specified illness, whichever happens first. | Tax-free lump sum (one payout only, after which the policy usually ends). | A CIC claim can use up the life cover, leaving no life payout later. |

Critical illness cover pays on diagnosis, not on death. Here are four situations where that distinction can make the difference between getting through it and financial collapse.
Treatment timelines are measured in months. Recovery adds more months after that. A serious cancer diagnosis in 2025 involves an average of 8.4 months of active treatment, according to NHS England pathway data. If your sick pay ends at month three and you cannot return to work until month nine, that is six months of your salary missing. With a mortgage, a family, and no income protection in place, a CIC payout at diagnosis puts you back in control of that timeline.
One in six heart attacks in the UK occurs in people under 45. Surviving a heart attack is not the same as returning to work the following month. Most survivors face a three- to six-month recovery period, sometimes longer. Life insurance pays nothing while you are alive, however serious things get. Critical illness cover is specifically built for the financial gap that life insurance does not touch.
65% of all critical illness claims paid in 2025 were for cancer. When someone in your household gets a serious diagnosis, the whole household’s finances shift. One person is managing treatment, the other is managing everything else, and someone’s income has dropped or stopped. The only policy that responds to that moment is one that was already in place before it happened.
A 35-year-old non-smoker can buy £100,000 of critical illness cover for roughly £25 to £45 a month. The average CIC payout in 2025 was £67,000. Spread across a 12-month recovery period, that is £5,583 a month available to cover a mortgage and bills while you are not working. The question is not whether the premium seems expensive. It is what the alternative actually looks like.

A 41-year-old self-employed tradesperson is diagnosed with stage 2 breast cancer. She has no critical illness cover. Savings were the plan. Statutory Sick Pay does not apply to the self-employed. Nine months of treatment and partial recovery later, her personal savings are gone. The business, which depended on her being physically present, has lost most of its client base. The financial hole is deeper than the medical one.
Same diagnosis. Same self-employment status. A critical illness policy taken out three years earlier cost roughly £38 a month at her age and health profile. It pays a tax-free lump sum on confirmed diagnosis, before treatment even begins. That money covers the income lost during treatment, two private consultations that cut her waiting time from 11 weeks to 18 days, and enough breathing room to keep the business active while she recovers. She comes back to work in month ten with clients still in place, not starting from scratch.
Clear,honest answers to the questions we hear most from clients and introducers.
More than 89% of individual critical illness claims were paid out in 2025, according to ABI figures. Most insurers paid over 90% of the claims they received. The perception that insurers look for reasons to decline claims is not supported by the data. The average payout in 2025 was £67,000.
Life insurance pays nothing while you are alive, however serious the diagnosis. Critical illness cover pays on confirmation of a covered diagnosis, before treatment begins, as a tax-free lump sum. The gap between the two products is the period of illness, treatment and recovery where income has dropped and costs have increased. That is exactly when a CIC payout makes the biggest difference
All UK critical illness policies must cover a minimum set of conditions defined by ABI Minimum Standards. These
include most cancers, heart attack, stroke, multiple sclerosis and major organ transplant. Cancer accounts for
65% of all CIC claims paid in 2025. Policies vary on the additional conditions covered beyond that minimum, which is one reason it is worth comparing definitions rather than just the premium.
Underwriting decisions depend on your full medical history, not a single event. A health scare does not automatically mean exclusions or declines. Many conditions are covered at a standard premium. Others may result in a rated premium or a specific exclusion on that condition alone. A broker can approach insurers on your behalf and find out what is available before you formally apply.
