How does Guardian compare?

While Guardian is a strong provider, the best critical illness cover policy for you depends on your age, health, occupation, and financial commitments. We always recommend comparing the whole market — Guardian may or may not be the best option for your specific profile.

Claims performance

Guardian publishes annual claims statistics showing their payout rates. Major UK insurers typically pay out 97–99% of life insurance claims and 90–95% of critical illness claims. Always check the latest published data before buying.
