Pay by bank account

A new way to top up your savings

We've introduced a new way to top up your NS&I savings accounts: Pay by bank account.

It means you can make deposits through our website without needing to enter your card details or any reference numbers, so it’s quick and easy to use. And it's highly secure as you will approve each payment through your bank’s app.

How it works

When you use Pay by bank account we’ll securely transfer you from our website to your bank’s app to approve the payment. Because you are doing this directly through your bank, you benefit from your own bank’s security. With many banks, you can also check your balance before any money leaves your account – putting you in complete control.

Approving a payment through your bank’s app on your smartphone or tablet is normally very easy, especially if you use your face or fingerprint ID to log in. You can also approve a payment through your bank’s website, but your bank may ask for additional security steps such as a card reader or one-time passcode.

What do I need to get started?

  • An NS&I account that you can top up online
  • A UK bank account that you can access online through your bank’s app or website

Is it safe?

Yes, it’s very safe. Pay by bank account is based on Open Banking technology, which has been established in the UK for over 5 years. We use a trusted provider called Ecospend to securely connect with all the major banks in the UK, and most of the smaller banks too. Ecospend is an authorised payment institution regulated by the FCA.

Handy tips

  • If you use your bank’s app on your smartphone or tablet and can use your face or fingerprint ID to log in, you won’t even have to enter your bank’s password.
  • Even if you log in to our website on a computer, you can still approve the payment in your bank's app by scanning a QR code. You’ll see the QR code on the screen after you’ve entered the amount. Just scan the code with your smartphone or tablet, and you’ll be directed to your banking app to approve the payment. To do this, turn on your camera and point your phone or tablet at the code (no need to take a photo). With some devices, you may need to download a QR code scanner app.
