Why claim statistics matter

Insurers in the UK publish annual claims statistics showing what percentage of critical illness claims were paid versus declined, and the most common reasons for decline — genuinely useful data for understanding how reliable this type of cover actually is in practice, beyond marketing claims.

What the published data generally shows

Industry-wide, the large majority of critical illness claims are paid — often in the region of 90% or higher across the industry as a whole, though this varies somewhat by insurer and by year. This suggests that, for policies bought and maintained with full and accurate disclosure, claims are paid more often than the occasional high-profile "declined claim" news story might suggest.

Common reasons for a declined claim

  • The diagnosed condition not meeting the policy's precise medical definition for that illness
  • Non-disclosure of a relevant pre-existing health condition at the time of application
  • The condition not being on the specific list covered by that particular policy
  • Not surviving the policy's minimum survival period after diagnosis, where one applies

Why disclosure is the biggest controllable factor

Non-disclosure is consistently one of the most common reasons for declined claims — and it's also the factor most within your control at the point of applying. Being thorough and honest about your health history when applying, even for things that seem minor or long resolved, meaningfully reduces the risk of a claim being declined later.

Using claims data when choosing a provider

Comparing published claims-paid statistics across insurers, alongside price and the specific conditions covered, gives a fuller picture than price alone — a slightly cheaper policy from an insurer with a notably lower claims-paid rate isn't necessarily the better overall choice.

Key takeaways

  • UK insurers publish annual critical illness claims statistics, showing generally high payout rates.
  • Non-disclosure at application is one of the most common, and most avoidable, reasons for a declined claim.
  • Compare claims-paid statistics alongside price when choosing a provider, not price alone.
  • Full, honest disclosure at application is the single biggest factor within your control.
