How to Charge Utilities for an Up/Down Duplex with One Meter

[Calvin D.]

I'm renewing the leases for a duplex that has 2 units: upstairs (3 bedroom, 3 people) and basement (2 bedroom, 2 people + 3 pets). There is one meter for both units. The strategy I have been using as recommended by my tenant placement service isn't working for me with the current higher utility costs (I won't clutter this question with an explanation of it but can do so if helpful). How do people in this position administrate utilities? Should I have the bill in my name, show to tenants when it arrives and have them pay me 2/3 and 1/3 of the bill? Have it in one of their names and get them to tackle it? I know there will be pros and cons to both but if anyone has a strategy that is really working for them, I'd love to know about it.
