Landlord : Who should pay Con Edison

Maybe make an appointment with NG to have the meter locked at a future day (eg 7 days) and let the tenant know that you’ve been billed b/c they didn’t turn it on and that if they would like to continue the service (what does it run–stove, water heater?, let them know), they have 7 days to switch it to their name or the utility company will be turning it off. No need to be mean when telling them, but just conveying the facts and you wanted to give them time to take care of it should they want to have gas. It’s sad, but I know some seemingly together adults who rent and could very well be that clueless about such things–that they needed to put it in their name or even which appliances use gas vs electric.
