Critical illness insurance is taken out to cover you either for life or for a set period of time against certain critical illnesses, diseases and medical conditions. It differs from life insurance in that life insurance pays out should you die. Critical illness insurance pays if you become physically or mentally impaired through illness or disease.

A policy to cover you for critical illness will pay out a tax free lump sum if you should fall victim to one of the illnesses defined within the policy. All that is needed to make a claim is the diagnosis by your Doctor of one of the illnesses or conditions defined in the policy; there is usually no requirement for you to prove loss of earnings or for you to need any special medical treatment.

Points to consider when thinking of taking out this form of insurance is that the sum and terms are decided at the outset when you take out your policy.

In order for the policy to pay out then you must survive for at least 28 days after the condition or illness has been diagnosed.

Once the set time of the policy has passed and you haven't been diagnosed as having a serious illness or condition then there is no payout and the policy simply ceases.

Before deciding on whether or not to take out critical illness insurance you should take several factors into consideration. The most important thing to decide is how much money you would need if you were to become critically ill and then decide how long you would need the cover for.

You will also have to take into account the various illnesses that are covered as these can vary from company to company. Another thing to take into account is that different companies have different exclusions within the policies so it is important that you read all the small print.
