Workplace pensions usually have an employer contribution, so that's essentially "free money", in a sense, as your company pays in a percentage as well. A private pension is your money only, but has been invested, so you get an amount of interest on it throughout the time you're paying in. You get your lump sum, then a regular amount throughout your retirement. The state pension is determined by the amount of tax you've paid in your lifetime, which is why there has been such uproar about women's pensions and the age change for claiming, as so many women are much worse off due to having brought up families rather than working, when this was commonplace in the 60's/70's/80's. State pension should never be affected by anything other than the amount of tax (or stamp) paid over your adult life,and private pensions are investment so essentially your own savings, and shouldn't ever be affected by any other entitlement. If people currently have never or rarely worked in their lives, they will get a minimum state pension, though will then receive benefits to whatever the current level is. Also, your state pension will start at the government set age (68 I think at the minute) whereas your private/ workplace pensions will start at the age it was set at when you started it, usually 60
