Can I automatically buy more Bonds with my prizes?
Yes, you can choose to automatically reinvest any future prizes you win. And it’s a good way to boost your chances of winning again.
To do this, simply log in and click 'View account' for your Premium Bonds. Then click 'Change details' and select 'Yes' from the 'Reinvest prizes' dropdown menu. Remember to click 'Save' when you've finished.
