Critical illness cover (CIC) is a type of insurance which provides a significant one-off payment if you are diagnosed with a specified life-threatening condition – specified being the important term, because if your illness isn’t in the terms and conditions – you won’t get the payment. Over recent years, critical illness cover has gained in popularity due to lower costs and apparent simplicity.

Critical illness insurance can be sold as part of a mortgage package or additionally as a stand-alone policy. Critical illness cover can also be commonly associated with life insurance, with certain CIC policies paying out either on the diagnosis of a particular illness or on death, but not both, whilst other CIC policies pay out in both events.
