We are only able to accept Cash ISA transfers into our Online ISA from ISA providers that subscribe to the BACS Electronic ISA Transfer Services. If your current ISA provider is not on the drop down list, they must not subscribe to this service. This is to ensure our ISA transfers can be managed and transferred into your new account as quickly as possible for you. 

We are only able to accept cash ISA's transfers in and therefore we are unfortunately not able to accept stocks and shares ISA's.

Yes, you can transfer in up to three existing ISAs to your new Cynergy Bank Online ISA within the one application.

We will work with your existing provider to transfer your existing ISA savings to Cynergy Bank’s Online ISA. The process should be completed within 15 working days of receipt of your application or sooner. 

In addition, we will calculate your interest from the date we request the transfer from your existing provider to ensure that you do not lose out on any interest.

To log in please visit our website at and click the ‘Online Banking Log in’ button near the top of the page.

You can log in to Online Banking by visiting our website at and clicking the ‘Online Banking Log in’ button near the top of the page. This will take you to our secure log in page. You will need your User ID and passcode.

Only use a link from the official Cynergy Bank website and never use any other links. This applies to any computer that you use.

Ensure that your connection to Online Banking is secure by checking that you have a padlock or unbroken key in the bottom right of your browser window or alongside the address bar - this indicates that you are accessing a valid and secure site. All secure website addresses start with 'https' rather than 'http'.

Online Banking passcode: You can request a new passcode for Online Banking by using the 'Forgotten passcode' link on the Online Banking log in page.

Online Banking User ID: Your Online Banking User ID is contained in the Welcome email we sent you at account opening. If you don’t have a copy of this, you can request a reminder of your Online Banking User ID by contacting us.

If you need a reminder of your account details, log into Online Banking to view these in the ‘Account details’ section.

Once your account is opened, we will provide you with your account number and sort code. You can also view these in the ‘Account details’ section of online Banking. You use these details to make a deposit. Simply request the funds to be sent over from the account they are currently held in.

We accept most forms of electronic payments including Faster Payments, BACS and CHAPS. Please note; that we do not accept payment by debit card, direct debit, cheque or cash into our Online ISA.

When you make an online deposit into your Online ISA, it is likely your bank or building society will make your payment by Faster Payments. This will normally be virtually instant but in some cases could take a couple of hours. Your bank may have limits as to how much it will allow to be sent by Faster Payments so you may need to send more than one payment. If your bank does not use Faster Payments they will offer alternative payment options such as CHAPS.

Please check with the Bank or Building Society you are sending money from, to ensure they support Faster Payments. Alternatively, you can use the Sort Code Checker on the public website of the Payments Council to check if your bank or building society offers Faster Payments.

No, the Cynergy Bank Online ISA is not a Flexible ISA. All subscriptions will count toward your annual subscription limit, irrespective of any withdrawals you make. For example, if you subscribe £5,000 into your Online ISA in the 2022/2023 tax year and withdraw £4,000 in the same tax year, the maximum additional subscriptions you can now make into your Online ISA in the current tax year is £15,000, subject to subscription to other ISA e.g. if you hold and subscribe to a Stocks and Shares ISA.

No, there is no charge for any withdrawals from your Online ISA.

For most withdrawals, we will use the Faster Payments service to pay withdrawals to your nominated account. These payments usually complete within hours. For very high value withdrawals (greater than £50,000) we will use CHAPS which are guaranteed same day on the basis that your instruction is received before 3.30pm. Otherwise, they will be sent on the next working day.

The Faster Payments Service is a payment system used between banks and building societies to speed up the way electronic payments in Sterling are made and received in the UK. Payments usually complete within hours. We will process most withdrawal requests by Faster Payments, depending on the amount and time of withdrawal request.

Not all Banks and Building Societies offer this service though, so please check with the Bank or Building Society you are sending money to/from to ensure they support Faster Payments, alternatively use the Sort Code Checker on the public website of the Payments Council.

We will normally use Faster Payments for withdrawals however, in some cases we use CHAPS. CHAPS (Clearing House Automated Payments System) is the system used for the electronic processing of financial transactions where guaranteed payments are transferred between UK banks on the same day. We may use CHAPS to process higher value withdrawals depending on the withdrawal amount and time of withdrawal request. CHAPS payments usually clear on the same day if advised by 3.30pm on a Working Day.

There are cut off times for example if you ask us to make a CHAPS payment after 3.30pm on a Working Day or on a non-Working Day we will treat your instruction as having been received at the beginning of the next Working Day and this is when we will start processing it.

A nominated account is an account that you must provide us with at application that we link to your Online ISA. All external withdrawals, excluding transfers-out using the ISA transfers process, will be made to this nominated account. It must be an account you are a named beneficiary on with a UK bank or building society and must be able to receive Faster Payments.

You can request to amend your Online ISA nominated account via Online Banking. You will be required to enter a One Time Passcode to confirm your request. We will electronically validate that you are named on the new nominated account. If the account passes electronic validation it will immediately be activated and you can pay funds to it. If it does not pass electronic validation it will normally be ready to use after five working days. During these five working days you will not be able to pay funds away to the new nominated account however the existing nominated account will be remain active until the new nominated account is activated. In some cases we may request documentation from you and it may take longer to activate your new nominated account.

Yes. You can use a sole or joint account as your nominated account however, you must be a named beneficiary on the account.

We will provide your annual Online ISA statement following the end of the tax year. Your statement will be provided in Online Banking for you to view or print. We will send you an email to let you know when it is available.
