Income Protection is a type of insurance that pays you a regular income if you can no longer work due to an illness or injury.
If you are self employed, you are not entitled to state illness benefit. If you are employed, you should consider how long you will be paid by your employer if you are absent from work due to ill health.
Income protection will mean that you will continue to receive an income until you get back to work. If you are not well enough to go back to work you, will be paid until your chosen retirement age. With Income Protection there is also the considerable advantage that you can claim full tax relief on your contribution.
