Critical Illness Cover

About critical illness cover

Critical illness cover pays a tax-free lump sum if you're diagnosed with one of the serious conditions listed in your policy, such as cancer, a heart attack or a stroke. You pick the amount and the term, and the insurer sets a monthly premium based on your age, health and the conditions covered. It pays out on diagnosis, whether or not you carry on working. The money is yours to use however you need.

What you're covered for with critical illness cover comes down to the policy's definitions. Two policies can both name 50 conditions and pay out very differently, because one defines a heart attack, or an early-stage cancer, more tightly than the other. The cheaper policy is sometimes the one that pays less when you claim.

At Vintage Wealth Management, we treat critical illness cover as one part of your protection plan. It works closely with your life insurance and income protection, and often with the mortgage it's meant to cover. We look at what you already hold, including any cover through work, then recommend across the whole market and read the definitions so you're not caught out at claim time.

What is critical illness cover and how does it work?

Critical illness cover is an insurance policy. It pays you a tax-free lump sum of money if a doctor diagnoses you with one of the serious illnesses named in the policy.

You decide how much cover you want and how many years it should last. In return, you pay the insurer a fixed amount each month. If you're diagnosed with one of the listed illnesses while the policy is running, you make a claim and the insurer pays you the lump sum. The policy pays out once, and then it stops.

For a claim to be paid, three things all need to be true:

  • The illness you're diagnosed with is named in your policy.

  • Your diagnosis fits the exact definition the policy uses for that illness.

  • You live for a set number of days after diagnosis, usually between 10 and 28 days, depending on the insurer.

If even one of these isn't met, the insurer won't pay. This is why the wording of a policy is as important as the price. Two policies can cost almost the same and still cover you very differently.

You can spend the money on anything you need. Many people use it to pay off their mortgage, but it can also go towards medical treatment, changes to your home, childcare, or everyday bills while you're too unwell to work. The insurer doesn't tell you what to spend it on.

Critical illness cover pays out when you're diagnosed with a serious illness. This makes it different from two other types of cover. Life insurance pays out when you die. Income protection pays you a monthly income for as long as an illness or injury stops you working. Each one protects you against a different situation, and many people hold more than one at the same time.

What does critical illness cover include?

Critical illness cover pays out for serious illnesses named in your policy. Every policy has to cover cancer, heart attack and stroke as a minimum, because the Association of British Insurers sets that as the industry standard. Those three are behind the large majority of claims. Most policies go further and cover around 40 illnesses, while some cover 100 or more.

Here are the conditions almost every policy includes, and what generally has to be true for each one to pay out:

Condition What's usually needed to claim
Cancer A cancer that has reached a defined severity. Very early-stage or non-invasive cancers may pay less, or nothing.
Heart attack Medical evidence of a heart attack of a set severity, confirmed by tests.
Stroke A stroke that leaves lasting effects, not a temporary one that fully resolves.
Multiple Sclerosis A confirmed diagnosis, usually with some continuing symptoms.
Kidney Failure Both kidneys failing permanently, needing regular dialysis or a transplant.
Major organ transplant You've had, or are on the waiting list for, a transplant of a major organ.
Total permanent disability An illness or injury that permanently stops you working or looking after yourself.

The exact wording is set by each insurer, meaning two policies covering the same illness can still pay out differently. A policy might list "heart attack," but its definition decides how severe the heart attack has to be before you're paid. This is the part that's hard to judge on your own.

More expensive critical illness cover policies tend to cover longer lists, adding conditions such as Parkinson's disease, motor neurone disease, Alzheimer's and other forms of dementia, and loss of sight, hearing or speech.

How much critical illness cover do I need?

Start with enough critical illness cover to pay off your mortgage. For almost everyone, the mortgage is the largest bill, and clearing it means you keep your home even if you can't work again. Many people then add three to five times their yearly salary on top, which leaves a lump sum to live on while they recover.

To get closer to your own figure, add up what you'd need to cover and take off any protection you already have. That means looking at:

  • What's left on your mortgage

  • Any other debts, such as a car loan or credit cards

  • The income you'd need to replace, and for how many years

  • Extra costs like childcare, or changes to your home if an illness affects how you move around

Two people can land on very different numbers depending on their debts, their family and their income. A single first-time buyer might cover just the mortgage, while a couple with children often need considerably more. These examples show the range:



Situation Chosen Cover What it's for
Single, £180,000 mortgage, no children £180,000 Pays off the mortgage in full, keeping the home safe
Couple, £250,000 mortgage, two young children £300,000 Pays off the mortgage and replaces income for a year or two during recovery
Single, £120,000 mortgage, wants a recovery buffer £120,000 Pays off the mortgage and covers around two years of living costs

It's easy to pick a round number that sounds big and still falls short. A figure like £50,000 can look generous until you're paying off debts and covering bills through a long illness, when it runs out fast. If you want a figure worked out around your own mortgage, income and family, speak to one of our advisers and we'll size it with you.

Can you combine critical illness cover with life insurance?

Yes. You can buy critical illness cover on its own, or add it to a life insurance policy so both sit on one plan. Combined cover is the more common choice, mainly because it's cheaper, usually around 20% to 40% less than paying for two separate policies.

Combined cover has one important limit. Most of these policies pay out only once, on whichever happens first, a critical illness diagnosis or your death. If you claim for a critical illness and the policy pays, the policy then ends, and there's no life cover left. Your family wouldn't get a second payout when you die.

Two separate policies cost more, but each can pay out on its own. You could claim on the critical illness policy after a diagnosis, recover, and still leave your family the full life insurance payout later. If people depend on your income, two separate policies protect them even after a critical illness claim.

How often does critical illness cover pay out?

Insurers paid out £1.3 billion in critical illness claims in 2024, with an average payout of £67,600, according to the Association of British Insurers. Across all protection insurance, more than 97.9% of claims are paid. When a claim is turned down, it's almost always for one of two reasons, and both can be avoided.

The first is non-disclosure. If you don't tell the insurer about a health condition when you apply, they can refuse the claim later, even if the thing you left out feels small or unrelated. The second is the diagnosis not fitting the policy's definition. The illness is real, but the wording sets a bar it doesn't reach, such as a cancer caught very early, or a heart attack the policy doesn't count as severe enough.

You avoid the first by answering every medical question on the application fully and honestly. You avoid the second by choosing a policy whose definitions are broad, rather than the cheapest one you can find.

This is why people use an adviser for critical illness cover. We check the application is complete before it goes in, and we compare the definitions across insurers, so the policy you end up with is one that pays when you claim.
