When you select a Critical Illness from the list below, you will see a typical definition of what is covered by a Critical Illness policy followed by a 'plain English' explanation, where available.

Please note: not all Insurance Companies will utilise these specific definitions and explanations.

The publishers are indebted to a number of leading companies who have allowed us to use their 'plain English guide' to explain these medical terms, as well as NHS Direct Online and the National electronic Library for Health.
