# Do we need to have our own SUN (Service User Number)?

No, if you are unable to obtain your own SUN then you can come onto the Interbacs Facilities Management Service which is where we will sponsor you onto one of our own SUNs and make Direct Debit collections on your behalf. We will then take care of any administrative work for things such as dealing with failed payments. Then we will transfer all the successfully collected funds to your account. To find out more about the service get in contact with us.
