What Makes a Good Critical Illness Cover Policy?
Critical illness cover quality is determined by more than just the monthly premium. The best policies combine:
- High number of covered conditions — more conditions means more scenarios where the policy pays out
- Quality of condition definitions — broader definitions mean more claims are accepted
- Severity-based/additional payouts — partial payments for less severe diagnoses
- High claims payout rate — the percentage of claims actually paid
- Children's cover — whether children are covered as standard
- Competitive premium — the monthly cost relative to the cover provided
