Heat Sub-metering


This tipsheet provides information about heat sub-meters. These sub-meters have been installed in some rental properties as a tool to measure the heat used by tenants. Landlords have used readings from the heat sub-meters to charge their tenants for heat.

The Government of Alberta introduced new rules for residential heat sub-meters on November 18, 2009 as part of the Fair Trading Act. These rules apply to businesses, including landlords, who supply residential heat sub-meters. The rules require landlords to only use certified heat sub-meters and to disclose meter readings and billing details to their tenants. The rules are detailed in the Energy Marketing and Residential Heat Sub-metering Regulation.

This regulation protects tenants who pay for heat as a separate charge from their rent. Tenants whose heat is included in their rent payment will not be affected by the regulation.

A heat sub-meter is a device that measures the units of energy to a rental unit for the purpose of heating. It does not include a master meter for the whole building.

The new regulation applies despite any contract, whether made before or after the coming into force of this regulation.

About the Regulation 

The Energy Marketing and Residential Heat Sub-metering Regulation applies to everyone including landlords that provide heat services to rental units occupied by a tenant. The regulation applies only to residential units not to businesses.

For buildings currently using heat sub-meters, heat used before the regulation came into force can still be billed by the supplier. Heat used after the regulation became law cannot be billed using a heat sub-meter.

Offences and Penalties 

The Energy Marketing and Residential Heat Sub-metering Regulation does not allow anyone to charge a tenant for heat based on readings taken from a heat sub-meter unless the heat sub-meter is approved for use under the Canada’s Weights and Measures Act. It is an offence to charge a tenant for heat using readings from an uncertified heat sub-meter.

If anyone uses a sub-meter that is approved under Canada’s Weights and Measures Act there are rules that must be followed. They must disclose in writing to the tenant:

  • sub-meter readings

  • amount being charged from the sub-meter reading

  • amount being charged for administrative or other fees

  • the method used to calculate an amount from the reading, and calculate administrative or other fees.

Under the Fair Trading Act the penalty for an offence is a maximum fine of $100,000, up to two years in prison, or both.
