If you click on the menu in the top right hand of your dashboard, you will then be able to then select the 'pause contribution' button. This will direct you to an option to 'pause payment'. This means all of your future recurring payments into your pension have been paused.
When you'd like to resume paying in, go ahead to the 'add money' button on your dashboard. Then simply select the payment method you'd like to use and how much you'd like to pay to resume your payments.
To make things easier, the details of your payment method will be saved from last time!
