How long will it take for a bank transfer to show in my savings account on the Tandem App?

In most cases your money will be in your account within 2 hours, however sometimes this may take up to 24 hours to arrive and show in your account.

Why do I have to connect an external bank account?

By connecting your bank account, we have verified that the account belongs to you and provides fraud protection for both Tandem and you.

What should I do if my external bank account fails to connect in the App?

If your bank account fails to connect to the app, this could be due to a service or technical difficulty. We recommend that you retry this action after a few minutes.

If you’re still experiencing issues, then contact our customer service team at or by calling 020 3370 0970.

How do I find my savings statements in the app? And how often are these issued?

Tap on the person icon in the upper left to go to your account and settings, then tap on Important documents where you can view your statements that will be issued on a monthly basis for an Instant Saver, and annually for a Fixed Saver. You can also see your personal details, app details and additional information about how to contact us from this screen.

Will I receive a Certificate of Interest? When will that be issued, and what’s included on the certificate?

We send you a certificate of interest annually, shortly after the closure of the tax year. The document confirms the interest you’ve earned within the previous tax year. Certificates of interest will be available in the app.

You can also request a copy of your certificate of interest for the previous tax year at any time - just call us on 0203 370 0970, and we’ll sort it out 8am-6pm Monday to Friday (including bank holidays).
