There is not such an option for excess utility uses within the AirBNB pricing solution.
I see 2 options for this kind of request
1. you can state it clearly in your house rules including the detailled fees.
and then charge it at the end through AirBNB additional charges. But there is no guarantee that the guest will pay.
then you could do a reclamation through AirBNB but once again, no guarantees that AirBNB will accept to collect those fees.
2. Or you could have a higher rate for your house and I forme the guest, at the beginning of your add what amount you willl refund if the utilities have been used below a certain threshold that can be calculated easely by the guest themselves.
