There are different options available to those who wish to invest more for their retirement - for example:
Depending on your current pension arrangements, you may not be able to change the payments made to your main pension plan. For example, some types of company pension would require you to set up a separate contract for any additional payments you wish to make.
Reducing your payments will result in a lower plan value and will reduce your future pension.
Please speak to a financial adviser for more information about the limits that apply to your plan. There may be a cost associated with obtaining advice.
