This interest rate applies to accounts opened on and after 4:00pm Tuesday 23 January 2023.

Can Cynergy Bank change the interest rate?

Yes, the interest rate may change.

Please note that if we increase the interest rate of your Business Saver issue, we may make the change immediately and notify you within a reasonable time afterward, either by email or on our website.

If we reduce the interest rate we will notify you 14 days before the change is made. If the Balance of your account is less than £100, we will not be required to give you notice ahead of making a change.

Please see Business Saver Conditions for further details.

How do I open and manage my account?

Business Saver customers who are 18 or over and a UK resident can open an account online.

You will need:

  • The mobile phone number and email address for all signatories on the account
  • Details of a UK business current account in your same business name. This will be your 'nominated account' - all deposits must come from this account and all withdrawals will be paid to this account.

The minimum initial deposit is £1 and you can deposit up to £10 million in this account.

It’s important we receive your initial deposit within 14 days from opening the account online.

You can only use Online Banking to manage your account and make withdrawals.

For added security, when you use Online Banking, you’ll need to download and register our Authenticator App (available for free on Google Play or the Apple App Store) or request a Digipass®.

You will need access to the Authenticator App or Digipass every time you login and make any actions on your account. This added security step helps us know that it is you making the transaction so we can keep your account safe.

For more information about Authentication and guidance help, please see our guidance pages here.

You may contact us by Secure Message via Online Banking, by telephone or in writing using the address or other contact details we have given you or which appear on our website. Please note we are unable to take transaction requests through these channels.

Can I withdraw money?

You can make unlimited requests to withdraw your money at any time.

You won't be charged a fee for withdrawals.

All withdrawals under £50k will be paid into your nominated account using Faster Payments. Payments over £50k will be sent via CHAPS. 

Withdrawals over £50k made before 3.30pm on a working day will arrive in your nominated account by the end of the next working day. Withdrawals over £50k made after 3.30pm or at the weekend will arrive no later than the end of the 2nd working day.

At times, it may be necessary for your payment to be put through some additional security checks, to make sure it’s genuine. This means it might take a little longer than usual to reach its recipient. Please don’t attempt to make the payment again while these checks are taking place.

Additional Information

Interest will be paid without deduction of tax. You will need to deduct tax yourself by declaring it as part of your annual tax return.
