Investment Account FAQs
-
You can only use your Investment Account by post.
When you make a cheque deposit or withdrawal, we’ll send you a record of your transaction. We’ll also send you a statement every January showing you all your transactions, plus your interest.
-
Only a parent, guardian, grandparent or great-grandparent can open an account and make deposits for a child.
Until the child’s 16th birthday, the parent or guardian nominated on the application looks after the account and we’ll send all correspondence to them.
-
The minimum you can withdraw is £1 and at least £1 must remain in your account to keep it open.
You can withdraw money from your Investment Account using an online form, without having to send us any post.
Withdraw from my Investment AccountYou’ll need your NS&I or account number to hand, as well as your bank account details.
Or complete a withdrawal form and send it to us.

The interest you earn on most savings will count towards your taxable income. But this doesn’t mean you’ll have to pay tax on it. It all depends how much interest you earn in total and what rate of tax you pay. You can find out more in our Help section.

We’ll ask you as part of your application if you’d like to save with someone else. You’ll each get your own login details so you can manage your account.

We’ll give advance notice of any rate changes by publishing adverts in a range of newspapers and by updating our website. When the rate is going down, we’ll also contact you personally in advance to let you know.
