I would call PPL for this information. You may have an issue where the previous owner has an outstanding bill. They might have paperwork for you to fill out( if you go ahead with a purchase) that states that you do not know the previous owner, etc. They should be able to give out this information to you, just explain the situation. If the property has gas by propane tank, you may run into the same situation here as well. You will need to find out who owns the tank. That can easily be found on the tank lid area.
I hope this information helps and feel free to call/email me if you have any further questions!
