Critical Illness Cover Explained
Critical illness cover pays you a tax-free lump sum if you're diagnosed with one of a list of serious conditions, such as certain cancers, a heart attack or a stroke. The money is yours to use however you need: clearing the mortgage, adapting your home, paying for treatment, or simply taking the financial pressure off while you recover. This guide explains what's covered, why the small print matters so much, and how it compares with income protection, as general information to help you weigh up your options.
- ✓It pays a one-off tax-free lump sum on diagnosis of a serious condition on the policy's list, whether or not you stop working.
- ✓Commonly covered conditions include certain cancers, heart attack and stroke, but the exact list and definitions vary by insurer.
- ✓Definitions and severity matter: not every cancer or heart condition meets the policy's definition, so cover quality varies a lot.
- ✓It's often bought alongside life insurance, and many policies can include cover for your children.
- ✓It's not the same as income protection, which pays a regular income for as long as you can't work.

What it pays and how
Critical illness cover pays a single lump sum if you're diagnosed with a condition listed in your policy and survive a short qualifying period (often 10 to 14 days). You can spend it on anything, there are no restrictions:
- ✓Paying off or reducing the mortgage
- ✓Adapting your home or car for a disability
- ✓Covering lost income while you, or a partner caring for you, are off work
- ✓Private treatment, recovery costs, or simply peace of mind
Which conditions are covered
Most policies cover a core set of serious conditions, and better policies cover many more. Typical examples:
- ✓Certain cancers (of a specified severity)
- ✓Heart attack and stroke
- ✓Multiple sclerosis, Parkinson's and other serious neurological conditions
- ✓Major organ transplant, kidney failure
- ✓Loss of sight, hearing or limbs
Children's cover and combining with life insurance
- ✓Many critical illness policies include cover for your children at no or low extra cost, paying a smaller lump sum if a child is diagnosed with a covered condition
- ✓Critical illness is frequently added to a life insurance policy. Check whether it pays out separately, or whether a critical illness claim reduces or ends the life cover ('accelerated' cover)
If keeping both protections fully intact matters to you, separate policies may be better than a combined one, an adviser can explain the trade-offs.
Critical illness vs income protection
It helps to see them side by side:
- ✓Critical illness cover, one lump sum on diagnosis of a named serious condition, paid whether or not you're off work, but it won't help with the many illnesses and injuries that aren't on the list
- ✓Income protection, a regular income for as long as almost any illness or injury keeps you off work, including mental health and back problems
For comprehensive protection, many people combine income protection (for the wide range of things that stop you working) with critical illness cover (for the big diagnoses). See our insurance overview to compare.

Frequently asked questions
What does critical illness cover pay out for?
It pays a one-off tax-free lump sum if you're diagnosed with one of the serious conditions listed in your policy, such as certain cancers, a heart attack or a stroke, usually after a short survival period. The money is yours to use however you like, for example to pay off the mortgage, adapt your home, or replace lost income. The exact list of conditions and how they're defined varies between insurers.
Does critical illness cover pay out for any cancer?
Not necessarily. Policies cover cancers of a specified type and severity, so very early-stage or less severe cancers may not meet the full definition, or may trigger only a smaller 'additional payment'. This is why the quality and wording of the definitions matters more than the headline price, two policies that both 'cover cancer' can pay out very differently.
Should I get critical illness cover or income protection?
They do different jobs. Critical illness cover pays a lump sum on diagnosis of a named serious condition, whether or not you're off work, but it won't help with the many illnesses and injuries that aren't on the list. Income protection pays a regular income for as long as almost any illness or injury keeps you off work. Many people combine the two for fuller protection.
Can I include my children on critical illness cover?
Often yes. Many critical illness policies include children's cover at no or low extra cost, paying a smaller lump sum if your child is diagnosed with a covered condition. The details, including the conditions covered and the amount, vary by insurer, so check the policy wording.
