Life insurance and critical illness cover are often mentioned in the same breath, and it’s a fair question: if you already have life cover, do you really need critical illness cover as well? The honest answer is that they protect against different things, and for many people, both have a role to play.
What life insurance actually covers
Life insurance (life assurance) pays out a lump sum to your beneficiaries if you die during the policy term. It’s designed to protect the people who depend on you financially — covering things like a mortgage, ongoing living costs, or your children’s future, after you’re gone.
What critical illness cover actually covers
Critical illness cover pays out a tax-free lump sum to you, while you’re still alive, if you’re diagnosed with a specified serious illness covered by your policy — commonly things like cancer, a heart attack, or a stroke. It’s designed to help with the financial impact of serious illness: time off work, treatment costs, adapting your home, or simply having breathing room while you focus on recovery.
The key difference
Life insurance protects your family if you die. Critical illness cover protects you and your family’s finances if you become seriously ill and survive. Survival rates for many serious conditions have improved significantly, which means the financial gap during recovery — when you might be unable to work but still have a mortgage and bills to pay — is a very real risk that life insurance alone doesn’t address.
When each one matters most
- If you have dependants who rely on your income, life insurance is usually the priority.
- If you’d struggle financially during a period of serious illness and recovery — for example, if you’re self-employed with no sick pay, or your household relies on two incomes — critical illness cover fills a gap life insurance doesn’t.
- Many people combine both, sometimes on a single policy (life insurance with critical illness cover added), which can be more cost-effective than buying two separate policies.
What critical illness cover doesn’t do
It’s important to understand the limits. Critical illness policies only pay out for conditions specifically listed and defined in the policy, and the severity of the diagnosis usually has to meet the policy’s definition — not every illness or every stage of an illness will qualify. Policies vary between insurers, so the exact list of covered conditions and the definitions used matter.
Making the decision
There’s no one-size-fits-all answer. It depends on your income, your savings buffer, whether you have dependants, your job (and any sick pay or income protection you already have through work), and your budget. The right combination of life and critical illness cover looks different for a self-employed parent than it does for an employed couple with no children.
Policy terms, covered conditions and definitions vary between insurers and change over time — always check the specific policy documents rather than relying on general descriptions.
