How to Compare Critical Illness Cover
When comparing critical illness cover, the number of conditions listed is far less important than how those conditions are defined. A policy covering 100 conditions with narrow definitions may pay out less often than one covering 50 with broader definitions.
The ABI Minimum Standards set the baseline, but providers differ significantly above this floor. The FCA Pure Protection Market Study is actively reviewing CI product value and claims ratios across the market.
Key factors to compare: conditions covered, definition severity thresholds, claims acceptance rates, and children's cover included.

Critical Illness Cover Comparison FAQs
Which is the best critical illness cover provider?
It depends on your priorities. Aviva has the most transparent claims data (97.9% paid). Legal and General has the broadest condition definitions. Royal London offers a Helping Hand support service. AIG is competitive for younger applicants. Always compare at least 3 providers.
How many conditions should CI cover include?
Quality matters more than quantity. The core 3 conditions (cancer, heart attack, stroke) account for 85%+ of claims. Whether a policy covers 40 or 100 conditions matters less than how those conditions are defined.
What does the ABI minimum standard require?
The ABI Minimum Standards require all CI policies to cover cancer, heart attack and stroke as a minimum baseline. Most providers go well beyond this, covering 40-100+ conditions.
Should I get standalone CI or combined with life insurance?
Combined is cheaper but only pays out once. If you claim for CI, you lose the life cover. Standalone CI keeps your life insurance intact. For comprehensive protection, consider two separate policies.
