Victoria's 2027 Gas Hot Water Rules: What Actually Changes
Published 10 August 2026 · 6 min read
From 1 March 2027, when a gas hot water system in an existing Victorian home reaches the end of its life, it must be replaced with an electric alternative such as a heat pump. Repairs are still allowed. Gas cooking and gas space heating in existing homes are not affected, and LPG is not affected at all.
That is the whole rule. Most of what circulates about it online is either an older draft proposal or a misreading, so this guide sticks to what the Victorian Government has actually published.
The three dates that matter
| Date | What changes | Who it affects |
|---|---|---|
| 1 January 2024 | No new reticulated natural gas connections for new dwellings, apartments or residential subdivisions that need a planning permit | New builds only |
| 1 January 2027 | All new homes and most new commercial buildings must be built all-electric | New builds only |
| 1 March 2027 | Gas hot water systems in existing homes must be replaced with electric alternatives at end of life | Existing homes |
The 1 March 2027 date is the one that affects homes already standing in Cranbourne, Berwick, Frankston, Pakenham and the rest of south-east Melbourne.
What the rule does not change
This is where most of the confusion sits. Under the published regulations:
- Gas cooking is unaffected in existing homes. You can keep cooking with gas, and keep a gas line piped to the barbecue.
- Gas space heating is unaffected for owner-occupiers in existing homes.
- Repairs are still allowed. If your gas hot water system breaks down and can be fixed, it can be fixed. The rule applies at end of life, not at every fault.
- You are not required to remove a working system. There is no forced disconnection and no deadline to replace a system that still works.
- LPG is not affected. Bottled and reticulated LPG fall outside these rules entirely.
- Existing commercial buildings are not required to electrify. New industrial, manufacturing and agricultural buildings are also exempt from the new-build rule.
An earlier draft proposal would have required all failed gas appliances to be replaced with electric. That is not what was adopted. The final regulations are narrower.
Rental properties have stricter rules
When the reforms were announced in June 2025, the Victorian Government also set new Minimum Energy Efficiency Standards for rental properties and public housing from 1 March 2027. Under those standards, both gas hot water systems and gas heaters must be replaced with efficient electric alternatives at end of life, not just hot water.
Further requirements were announced for the start of a new lease after that date, including ceiling insulation, draught sealing, a water efficient shower head and efficient electric cooling in main living areas. Landlords and property managers should check the current requirements directly, as the rental standards sit under separate regulations to the hot water rule.
Exemptions exist
The roadmap states that for existing residential buildings, exemptions are available where replacing a gas hot water system with an electric appliance may present some challenges. The detail of how those exemptions work is not something we can summarise accurately, so if you think your property may qualify, check with your local council or the Victorian Government directly rather than relying on a plumber's read of it.
What this means if your gas system is getting old
Gas storage hot water systems do not last forever, and most households replace rather than repair once a unit is well into its second decade. If yours is getting on, you have a choice available now that you will not have later: you can plan the replacement rather than make it in an emergency.
When a system fails on a winter morning, the decision gets made in a few hours. There is no time to compare quotes, check whether your switchboard has capacity for a heat pump, work out the best location for the outdoor unit, or look into rebates. After 1 March 2027, that emergency decision also has to be an electric one.
None of that means you should replace a working system today. It means that if yours is already near end of life, doing it on your own timetable is worth more than it looks.
What an electric replacement costs
Heat pump hot water systems run about $2,500–$4,000 installed in Melbourne before rebates. Solar hot water runs roughly $3,000–$8,000 installed. Both attract support: Solar Victoria offers a rebate of up to $1,000, or up to $1,400 for eligible Australian-made units, and federal small-scale technology certificates apply on top.
Rebate eligibility depends on your household, your existing system and your installer, so treat those figures as before rebates. A licensed plumber quotes after assessing the actual job, and if something unexpected is uncovered during the work, they pause, explain, and re-quote before continuing.

Questions people actually ask
Can I still replace my gas hot water system with another gas one?
Until 1 March 2027, yes. From that date, when a gas hot water system in an existing Victorian home reaches end of life, it must be replaced with an electric alternative.
Do I have to replace my gas hot water system in 2027?
No. The rule applies when your system reaches end of life, not on a fixed date. A working system can keep working.
Can I repair a gas hot water system after March 2027?
Yes. Repairs are still allowed. The replacement requirement applies at end of life, not to maintenance or repair work.
Does this affect my gas cooktop or gas heater?
Not in an existing owner-occupied home. There is no change to existing gas cooking or space heating appliances. Rental properties have separate requirements covering heaters.
What about LPG?
LPG is not affected. Bottled and reticulated LPG sit outside these rules, so regional homes and barbecues are unaffected.
What counts as end of life?
The regulations use the end-of-life test rather than defining it by age. In practice it is the point at which a system is being replaced rather than repaired. If you are unsure whether yours is repairable, that is a question for the licensed plumber who inspects it.
Are there exemptions?
Yes, for existing residential buildings where an electric replacement may present challenges. Check with your council or the Victorian Government for how they apply to your property.
