A pension paid to you when you retire by the State. The amount you get will depend on your National Insurance record (or on that of your marriage partner).
The basic state pension is paid to everyone. The level of pension you get depends on the amount of National Insurance contributions you pay over your working life.
State Pension (formerly known as Retirement Pension) is a contributory benefit payable to men and women who, upon reaching State Pension age, have paid enough of the right class of National Insurance contributions to qualify.
This is paid to everyone. How much you will get depends on how much you have paid or have been credited in National Insurance contributions by the time you retire.
