Income Protection was formerly known as Permanent Health Insurance (PHI) and is an insurance policy that pays out a percentage of your income if you are unable to work due to injury or illness. Income Protection pay-outs are tax-free and are paid directly to you, usually on a monthly basis.
This is the one protection policy every working adult in the UK should seriously consider and ironically it is the one that most people don't have. It is important to make sure that you are aware of how much and how long your employer would pay you for, if you were unable to work. Could you survive on savings or sick pay from work? If not, you will need some other way to keep paying the bills, Income Protection can help to do this.
