Transferring money from a Co-operative Bank account?
The above details are for a collection account that we hold with the Co-operative Bank. Please note, if you hold an account with the Co-operative Bank and are using their online facility to transfer funds into your Ecology account, you will need to use the Co-operative’s ‘bill payment‘ function. This is because it will allow you to quote a reference when making your transfer; without a reference, we may be unable to pay the money into your Ecology account.
