Is critical illness insurance worth it?
It can be worth a look if a serious diagnosis would leave you without income for months. That can be true if you are self-employed with no paid sick leave.
It may not be worth it if you have enough savings to cover months without income. It never replaces a health plan.2
What to do: Tell us how long you could go without income. We suggest only what fits.
What does critical illness insurance not cover?

We check these details with you before you choose.2

Heads up: Waiting periods and limits on conditions you already have can apply.
