Direct Debit Form
Demon Direct Debit Form
Direct Debit is a simple way to pay your bills. It is convenient and easy to setup. If you would like to pay by Direct Debit, then please download and print the Direct Debit Instruction Form here and return it to:
Demon Customer Services

Alternatively you can update your payment details and set up a Direct Debit online here if you only require one signatory for your account. You will need to have either your Hostname and Password or your Demon Account Number and Postcode to hand. If your account requires two signatories you will need to print out and return the Direct Debit mandate above.
