Notice Board:

Attention: Known malware threat                  



Fraudsters are trying to trick users into approving fraudulent transactions, by using known malware. The malware tries to trick users by offering an update to the e-Signer software using a pop-up window currently entitled ‘Install Shield Wizard Update’. On selecting ‘Next’, the user is prompted to enter their Smart Card and PIN to begin the download. On doing so, the user is unwittingly approving  fraudulent transactions.

Please be aware that Barclays or the eSigner software will never offer automatic updates in this way and any such pop-up window is fraudulent. If you are prompted to update eSigner software in this manner, remove your Smart Card immediately, disconnect the infected machine from the network and contact us immediately for additional support.

Always remember, you will only ever be prompted to enter your Smart Card and PIN when logging in, authorising a payment or approving an administrative change. If you see any other unusual or blank screens, please contact us

Service Update: This service is now being decommissioned

The Business Internet Banking Service is being decommissioned and all clients have been migrated. With immediate effect, clients should start to use our new cash management service Barclays.Net.

If you have any questions regarding the migration then please refer to your system administrator in the first instance. Alternatively you can contact the Barclays.Net Migrations helpdesk on 0330 156 0020 or your Relationship Team.  

Fraud monitoring                

As a bank your security to us is paramount. Therefore we are always monitoring for any suspicious activity on your account and may sometimes need to delay transactions that are out of character or deemed high risk until we can confirm that the payment being made is genuine.  To help us get in contact with you quickly and minimize any inconvenience we ask that your contact details are kept up to date.

If we do contact you, we’ll  never ask you to change the beneficiary bank details of a payment or ask you to reveal full security details (including smart card PINs)
If you get a message from someone claiming to be from our Fraud Team and you think it’s suspicious, call us back using the number from our website. 

24/01 - Making International Payments? - When making International Payments, please ensure that all mandatory information is included in the payment instruction.  In particular, when submitting an International Payment you must always provide a SWIFT ID or National Clearing Code to avoid your payment being delayed or returned. Please refer to the currency/country guides on the International Payment help site  for formatting instructions as well as important news updates including:             

26/10 - Mac OS 10.12 Sierra

Apple have recently released their new Mac OS 10.12 Sierra operating system for Macs. Please note, this operating system is not currently supported and may cause issues and prevent access to Business Internet Banking if installed. In line with our security strategy we will endeavour to support Sierra once it has gone through our complete testing and oversight process. Our Hardware and Software guidelines will be updated in due course. For a full list of supported operating systems and browsers, please see our Hardware and Software Requirements guide                              


If a supplier sends you a notice saying its bank account details have changed, or you get an email purporting to be from your business’ senior management requesting a payment be made to a new beneficiary, we strongly recommend you confirm these details face-to-face or verbally via a phone number you know and trust before making the payment. 

In line with industry practice and the Payment Service Regulations, payments are made on the basis of the account number and sort code you quote in an instruction only, and not the account name.  Account names frequently change and it is your responsibility to confirm the account number and sort code are correct.

To help protect you and your company against the latest scams, Barclays has produced a new short video to raise awareness on these latest trends. This is the latest release in our series of videos to help keep you safe from fraud which can be viewed below and should be viewed again periodically.
