How Long Does a Critical Illness Claim Take to Pay Out?

Most CIC claims are paid within 4–12 weeks of diagnosis confirmation — but the process varies. Here's what to expect step by step.

The CIC claims process

Unlike life insurance, which pays out on death (a clear event), critical illness claims require the insurer to verify that your condition meets the policy definition. This adds a step to the process but most straightforward claims are settled relatively quickly.

Typical timeline

  1. Notify your insurer — as soon as possible after diagnosis. Most insurers have a dedicated claims team.
  2. Submit documentation — diagnosis letters, consultant reports, medical records (1–2 weeks to gather)
  3. Insurer assessment — typically 4–8 weeks to assess the claim against the policy definition
  4. Payout — usually within 5–10 working days of approval
Total typical timeline: 6–12 weeks from notification to payout for a straightforward claim. Complex cases may take longer.

What can delay a claim?

  • Missing or incomplete medical documentation
  • Disputes over whether the condition meets the policy definition
  • Non-disclosure issues requiring investigation
  • Conditions not covered under the policy terms

What if my claim is declined?

If your claim is declined, first ask for a detailed explanation in writing. You can complain to your insurer, and if unresolved, escalate to the Financial Ombudsman Service (FOS) — free of charge. The FOS upholds a significant proportion of CIC complaints in favour of policyholders.
