Glossary: National insurance

A scheme originally established in 1944 to provide protection against sickness and unemployment as well as helping fund the National Health Service (NHS) and state benefits. NI contributions are compulsory and based on a person’s earnings above a certain threshold. There are several classes of NI, but which one an individual pays depends on whether they are employed, self-employed, unemployed or an employer. Payment of Class 1 contributions by employees gives them entitlement to the basic state pension, the additional state pension, jobseeker’s allowance, employment and support allowance, maternity allowance and bereavement benefits. From April 2016, to qualify for the full state pension, individuals will need 35 years’ of NI contributions.
