Critical illness insurance is designed to provide you with financial protection in the event that you are diagnosed with a critical illness during the term of the policy. This is particularly important if you own a property and are currently paying a mortgage. Whereas life insurance only pays out to your beneficiaries in the event of your death, if you are unfortunate enough to be diagnosed with a critical illness, your insurer will pay out a tax-free lump sum directly to you, to cover the cost of treatment and/or loss of earnings.
Critical illness cover was developed by insurers as modern medicine enabled more people to survive conditions such as cancer or strokes, but are not well enough to be able to return to work.
