about the legality, installation, and usage of sub-metered utilities.
Local municipalities may also enact their own specific ordinances."
"When you are in a sub-metered tenancy,
you’re not the client of the utility company.
your landlord is obliged to tell you, before you move in,
that you are living in a shared meter accommodation
and what percentage of that meter reading
you are expected to pay each month.
This should be agreed in writing.
In these circumstances you are referred to as a “sub-metered tenant”.
You do not have any formal relationship with the gas company
and any complaints regarding the service need to be made via your landlord,
who is responsible for the billing account."
