Payment default

Notwithstanding that in the normal course of business, settlement is deemed to have occurred with issue of the Certificate, should your bank reverse or reject your payment for any reason, the issue of a certificate made in relation to that transaction may also be revoked. This could have implications for the validity of the BASIX® certificate issued and the Department reserves the right to cancel or revoke an issued certificate, to prevent the issue of a BASIX® completion receipt or to suspend access to the BASIX®Assessment Tool or Service until the debt is settled. The Department will use reasonable endeavours to notify you of any default and provide you with the opportunity to settle the debt but will not be held liable for failure to notify.

You will not be entitled to receive a refund for a BASIX® certificate that is subsequently not lodged with a consent authority or that you otherwise do not benefit from, whether such non-lodgement was voluntary or involuntary. Any refunds, if provided, may be subject to an administration charge as published in the BASIX® Schedule of Fees and Charges.
