    Critical Illness Cover

    Written by Check Financial · 4 min read

    The short answer

    Critical illness cover pays a tax-free lump sum if you're diagnosed with a serious illness covered by your policy, such as many cancers, heart attacks and strokes. You can use the money however you need while you recover.

    Who It's For

    Critical illness cover suits anyone who would struggle financially through a serious illness. It is often worth considering when:

    • You have a mortgage or rent that would still need paying if you were off work for months.
    • Your family relies on your income.
    • You are self-employed and have no sick pay.
    • Your savings wouldn't cover treatment, home changes or a long recovery.

    Do I need it if I have life insurance? Life insurance pays if you die. Critical illness cover pays if you survive a serious illness and need time and money to recover.

    How It Works

    1. You choose an amount and a term, often to match a mortgage or a number of years of income.
    2. You take it on its own, or combined with life insurance. A combined policy pays once, on diagnosis or death, whichever comes first, and then ends.
    3. If you're diagnosed with a covered condition that meets the policy's definition, the insurer pays the lump sum. Some policies require you to survive a short period after diagnosis.
    4. You decide how to use the money, for example to clear or reduce your mortgage, replace lost income, or pay for treatment, care or adaptations.

    Many policies also make additional payments for less severe conditions, such as some early-stage cancers. Many include children's cover at no extra cost.

    The definitions matter more than the number of conditions. For the most common claims, cancer, heart attack and stroke, insurers follow minimum standards set by the Association of British Insurers. Beyond that, definitions vary. We compare them for you before you decide.

    How Much Cover, What It Costs and Tax

    How much cover. There is no single formula. People often base it on one or more of these:

    • Their outstanding mortgage.
    • One to two years of take-home income, to allow time to recover.
    • The likely cost of treatment, care or changes to the home.

    What it costs. The price depends mainly on your age, health and smoking status, the amount of cover and the length of the policy. It also depends on whether the cover is level or decreasing, and whether it's combined with life insurance. Critical illness cover usually costs more than life insurance alone, because a claim is more likely.

    Tax. A payout from a personal policy is normally tax-free.

    What It Doesn't Do

    • It doesn't pay for every illness. It only pays for the conditions listed in the policy, when they meet its definition.
    • Less advanced conditions may pay a smaller amount, or nothing, depending on the definition.
    • It doesn't pay a monthly income. For that, see income protection.
    • A combined policy pays once. After a critical illness claim, the life cover ends too.
    • It can exclude conditions you've had before. We'll tell you about any exclusions before you accept.

    Real Scenario

    Example scenario, not a real client

    A Serious Diagnosis, with the Mortgage Still to Pay

    A self-employed parent with a young family and a repayment mortgage is diagnosed with a cancer that meets their policy's definition.

    Outcome: Their critical illness cover pays a lump sum. They use it to reduce the mortgage and cover several months without work during treatment.

    Common Questions

    How many conditions are covered?+
    It varies widely between insurers. How each condition is defined matters more than the total.
    Are my children covered?+
    Many policies include children's cover for certain conditions at no extra cost. The amount and conditions vary.
    Can I claim more than once?+
    Most policies pay one full claim and then end. Additional payments for less severe conditions usually don't reduce the main cover.
    What if I've had a serious illness before?+
    You may still get cover, sometimes with an exclusion. See our pre-existing conditions guide.
    Is this the same as income protection?+
    No. Critical illness cover pays a single lump sum on diagnosis. Income protection pays a monthly income while you can't work, for any covered illness or injury.

    Income Protection

    Income protection pays you a regular monthly income if illness or injury stops you working. It keeps paying until you're well enough to return, the policy ends, or you reach the end of the claim period you chose.
