I already have an NS&I account

It only takes a few minutes to set up your online account.

If you’re 16 and over, you can manage your NS&I accounts online.

Have these details ready:

• Your personal details, including contact information
• Your account/holder’s number Tooltip
• Details of one of your NS&I accounts
• Your bank account details

You can’t register to manage an Investment Account online, but it will appear in your dashboard if you have other savings accounts.

• I’ve moved address since I opened my NS&I account

  If you’ve moved since you opened your account, please try to register with the address you lived in at the time.

  In some cases, we may not be able to match your address and you’ll need to complete and send a paper form.

  We’ll let you know if this happens when you register and tell you what to do next.

• I’ve recently opened an NS&I account

  You’re already registered if you recently applied for one of our accounts online or by phone. If you set your password when you applied or already have a password, you can log in without needing to register again.

  Sometimes we may send you a temporary password in the post, which can take a few days. If so, simply log in to change the temporary password to one of your choosing.

  If you don’t receive a password, please call us.

• I’ve recently turned 16 or I have an account that I held as a child

  If someone set up a savings account for you when you were a child, you’ll now be able to manage it yourself.

  You’ll need to complete a registration form and send it to us first, as we need someone to witness your signature as proof of identity.

  Once we have this, you’ll be able to manage your accounts online (except for an Investment Account, which can only be managed by post).

  Download a registration form.

  Please ask a witness (anyone over 18 but not a family member) to write the following in a covering letter, which they’ll need to sign and date: “I certify that (your name) signed the enclosed form in my presence and that I am not a member of the same family”.

  We’ll also need your witness to print their name, address and occupation in the same letter. Please send the letter to us with the completed form.

Check if you have an NS&I account

Think you might have savings or investments with us, but you’ve lost the details? Or maybe you believe that a relative or client had an NS&I account before they died?

Ask our Tracing Service team to track it down.
