Critical illness cover pays a tax-free lump sum if you’re diagnosed with a specified serious illness during the policy term. Unlike income protection (which pays monthly if you can’t work), critical illness is a one-off payment — typically used to clear or reduce your mortgage, adapt your home, or fund treatment and care.

We discuss critical illness cover with every mortgage client, because understanding it helps you make an informed decision about whether it’s right for your situation.

What It Covers

Critical illness policies cover a defined list of conditions. All policies cover the core conditions specified by the ABI (Association of British Insurers), which include most cancers (with some exclusions for early-stage), heart attack, stroke, multiple sclerosis, kidney failure, and major organ transplant.

Beyond the core conditions, insurers compete on the breadth of their coverage. Some policies cover 40+ conditions, others cover 100+. More conditions doesn’t automatically mean better — what matters is whether the specific conditions that concern you are included, and how they’re defined.

Definitions matter enormously. Two policies might both list “cancer” but define the qualifying criteria differently. We compare policy wordings — not just condition counts — to ensure the cover you buy will actually pay out when it matters.

What It Doesn’t Cover

Critical illness cover has limitations you need to understand.

It only covers conditions on the policy’s defined list. If you develop a serious condition that isn’t listed, or that doesn’t meet the policy’s specific definition, you won’t receive a payout.

Pre-existing conditions are typically excluded. If you’ve already been diagnosed with a condition before taking out the policy, it won’t be covered.

Survival periods apply to most conditions — you must survive for a specified period (usually 14 days) after diagnosis before the claim is valid.

It’s a one-off payment. Once you claim, the policy ends. If you develop another condition later, you’re not covered.

How Much Does It Cost?

Critical illness cover is more expensive than straightforward life insurance because the probability of claiming is higher — you’re more likely to be diagnosed with a critical illness during your working life than to die.

Premiums depend on age, health, smoking status, cover amount, and policy term. As a rough guide, a healthy 35-year-old non-smoker might pay £40-£80 per month for £200,000 of cover over 25 years. Smokers and those with health conditions pay significantly more.

We always compare across multiple insurers because premiums for identical cover can vary substantially.

Critical Illness vs Life Insurance vs Income Protection

These three products do different things and aren’t interchangeable.

Life insurance pays out when you die. It protects your family and clears your mortgage if you’re not around.

Critical illness pays out if you’re diagnosed with a specified serious illness. You’re alive but potentially unable to work or needing to adapt your life.

Income protection pays a monthly income if you can’t work due to any illness or injury. It replaces your earnings for as long as you’re unable to work.

The ideal scenario is a combination that covers all three risks. But budget constraints are real, and we’d rather you had good cover for the most relevant risks than thin cover across everything.

Do You Need It?

There’s no universal answer. Consider what would happen financially if you were diagnosed with a serious illness tomorrow. Could you still pay your mortgage? Would you need to stop working? Would your family cope?

If the answer to any of those is uncertain, critical illness cover is worth considering. It provides a financial safety net at exactly the point where you need it most.

We’ll never pressure you into buying cover you don’t need or can’t afford. But we’ll make sure you understand the risks and options so you can make an informed decision.
