The key difference
Life insurance pays a lump sum to your beneficiaries when you die. Critical illness cover (CIC) pays a lump sum to you if you're diagnosed with a serious illness — such as cancer, heart attack, or stroke — while you're still alive. These are fundamentally different products solving different problems.
What does life insurance cover?
- Pays out on death during the policy term
- Used to clear a mortgage, replace income for dependants, or leave a legacy
- Cheaper than CIC for the same sum assured
- Essential if anyone financially depends on you
What does critical illness cover do?
- Pays out on diagnosis of a covered condition (30–50 conditions typically)
- Used to clear or reduce the mortgage, fund private treatment, adapt your home, or replace income
- You receive the money — not your family — while you're still alive
- More expensive than equivalent life insurance
Do you need both?
Many people benefit from having both. Combined life and critical illness policies — which pay out on whichever occurs first — are available from most UK insurers and can be more cost-effective than buying separately.
Which is more important?
If you have dependants relying on your income, life insurance should come first. If your mortgage is your biggest concern and you have savings to cover short absences, CIC may offer more practical day-to-day protection.
Frequently Asked Questions
Yes — and many people do. You can buy them separately or as a combined policy from most UK insurers.
Generally yes — because claims are more frequent. A serious illness diagnosis is statistically more likely than death during working age.
