Critical Illness Insurance — Overview
Critical Illness Insurance pays a tax‑free lump sum if you are diagnosed with, or receive treatment for, a serious medical condition listed in your policy. It originated in South Africa and has been widely used in the UK since the 1980s. Policies follow core definitions agreed by the Association of British Insurers (ABI), with many insurers offering additional conditions.

- A one‑off lump sum payment on diagnosis of a covered condition.
- Conditions must meet the insurer’s ABI‑aligned medical definition.
- Cover can be added to life insurance or arranged as a standalone policy.
- Some policies include Permanent and Total Disability as an additional benefit.
