There are very few people who would not benefit from critical illness protection. If you are worried that if you were diagnosed as suffering from a serious or critical illness you would need to rely on your friends, family or the State; then you should consider critical illness protection.
If you are diagnosed with a serious illness that prevents you from working, you and your family will no longer receive the income that you used to support the family home. Critical Illness cover will make sure that your family are financially secure by replacing your salary.
