In terms of private pensions, it may also be possible for you to draw from your private pension while working.
You will be unable to draw from a scheme and continue paying into it at the same time, however.
Private pensions are also taxable income, normally paid with tax deducted via PAYE.
Deferring a final salary, or defined benefit, pension, is less advantageous financially than deferring the State Pension, because the final salary pension will not compensate the holder for the period when they do not claim it.
Different schemes may handle deferring different depending on their individual terms and conditions.
Your private pension scheme’s rules govern the point at which you stop accruing further pension and schemes apply a pension age at which point you are expected to start claiming.
