The most obvious feature of a pension plan is the pension that you will get when you retire.
In PensionSaver and other personal pension plans the pension is known as an annuity. Once you have bought your annuity it will be paid for the rest of your life. So it's important that you get one that best suits your circumstances.
You'll need to choose some of the features of the annuity. Do you want one that increases each year, or stays at the same level?
Providing benefits for your dependant if you die before them is something else to think about.
Each feature that you choose will have an impact of the amount of income you receive. For example, choosing an annuity that increases each year will cost a lot more than one that doesn't.
