What Victoria's New Minimum Energy Efficiency Standards Mean for Your Rental Property
New Minimum Energy Efficiency Standards (MEES) are coming to Victorian rental properties, rolling out in phases from 1 March 2027. If you manage or own a rental property, here's what you need to know — and why starting the conversation now is the smart move.
What the Standards Cover
The new standards apply across six areas: heating, cooling, hot water, showerheads, ceiling insulation, and draughtproofing. Importantly, rental providers won't need to upgrade everything at once. Each standard has its own specific trigger — a circumstance that activates the requirement — so upgrades happen gradually and in response to real situations at the property.
How the Triggers Work
There are two types of triggers. For heating and hot water, the standard is activated when an existing system fails and cannot be repaired — there's no need to replace a working system early. For cooling, showerheads, ceiling insulation, and draughtproofing, the requirement kicks in at the start of a new rental agreement or when an existing agreement converts to a month-to-month arrangement.
This matters for planning: a property with an upcoming lease renewal in early 2027 could trigger several standards at once. Understanding what each property currently has will help avoid any last-minute surprises.
Heating and Cooling
From 1 March 2027, when an existing fixed heating system fails, it must be replaced with an energy-efficient electric system — either a non-ducted reverse-cycle air conditioner or heat pump with a 2-star or above GEMS rating, or a ducted electric heating system with a GEMS Heating Seasonal Performance Factor of 3.2 or above.
For cooling, properties without a fixed cooling system will need to meet the standard when a new rental agreement starts from 1 March 2027. By 1 July 2030, all rental properties in Victoria will need to comply. A reverse-cycle air conditioner can satisfy both the heating and cooling standards — worth considering if a heater replacement is already on the cards.
Hot Water
From 1 March 2027, when a hot water system fails and cannot be repaired, it must be replaced with an electric heat pump system. Gas hot water systems cannot be replaced with another gas system after this date. Rental providers with older gas systems should factor this into their long-term planning sooner rather than later.
Showerheads
At the start of a new rental agreement from 1 March 2027, all showers must be fitted with a 4-star WELS-rated showerhead. This is one of the simpler and more affordable upgrades. Note that current minimum standards already require 3-star showerheads — if a property doesn't have those yet, that needs to be addressed now.
Ceiling Insulation
Where a ceiling has no insulation or is only partially insulated, insulation with a minimum R5.0 rating must be installed at the start of a new rental agreement from 1 March 2027. If a property already has insulation across all ceiling areas — even if it's older or below R5.0 — it meets the standard. Only a qualified installer can carry out this work, and an electrical safety check must be completed before installation begins.
Draughtproofing
Starting from 1 July 2027 (note: this is later than most other standards), draught-sealing or weather-stripping must be fitted to all gaps around external doors, windows, and unsealed wall vents when a new agreement starts or converts to periodic. Door snakes and similar non-fixed products don't count. If the property has gas appliances, a licensed plumber must complete a gas safety check before any draughtproofing work is done — and draughtproofing cannot proceed at all if open-flued or flueless gas appliances are present.
Financial Help Is Available
Every upgrade under the new standards is eligible for a discount through the Victorian Energy Upgrades (VEU) program, with most discounts available now. Rebates for heat pump and solar hot water products are also available through Solar Victoria. These programs can significantly reduce the cost of getting compliant.
What to Do Now
The best first step is to review the current condition of each property — what heating, cooling, hot water, and insulation it has, and whether showerheads already meet the 3-star requirement. The Consumer Affairs Victoria website includes a practical "What this means for you" section for each standard at consumer.vic.gov.au/mees, making it straightforward to assess what may be needed when a trigger eventually occurs.
