Of course - you have complete control over your data.
You can unlink any of your bank accounts at any time. You can do this by going to your ‘My Account’ section, followed by ‘Manage Linked Accounts’ and selecting the bank account you’d like to unlink.
Please note that unlinking a bank account will remove all data associated with this account on your ClearScore.
However, if you link/unlink an account this information will not affect your credit report data (as this is provided to us by Equifax).
