Most people when they retire will get money from a variety of sources.
The state will provide a basic State Pension (perhaps including some additional pension if you are a man born before 6 April 1951 or a woman born before 6 April 1953) and, if you do not have much extra pension or savings, other benefits as well.
If you were a member of an employer's pension scheme at any time during your working life, you will get some pension from that.
These questions give a basic overview of the different type of pension. There are more detailed questions and answers about each type elsewhere on workSMART.
