A SIPP is a “wrapper” that contains the different investments you have spent your pension savings on so there are no guarantees on what you will receive in retirement.
How much you are able to draw will depend on a number of factors – the most important being how much you have paid into your SIPP and how your investments have performed over that time.
That is why it’s important if you have a SIPP that you have the time and expertise to be able to monitor your investments and be prepared to make changes if necessary.
