Victoria's gas ban what Melbourne South East homeowners need to do before March 2027
From 1 March 2027, if your gas hot water system reaches end-of-life and cannot be repaired, you must replace it with an efficient electric alternative. The most practical option for most Melbourne homes is a heat pump. Here's what the rule means for homes in Cheltenham, Bayside, and the surrounding suburbs, and what to do about it.

Key Takeaways
- From 1 March 2027: gas hot water must be replaced with a heat pump (or equivalent efficient electric system) at end-of-life in existing Victorian homes
- Gas cooking and space heating: owner-occupiers are NOT required to switch under current rules
- LPG (bottled gas): exempt from the hot water ban, like-for-like replacement still permitted
- Rebate stack available now: up to $2,700 off a heat pump hot water system (Solar Victoria + VEU + STCs combined)
- Solar Victoria income threshold dropped to $150,000/year from 1 July 2026, households above that can still access VEU ($630) and STCs ($500–$700)
The timeline: key dates for Victorian households
| Date | What changes |
|---|---|
| 1 January 2024 | New residential builds requiring a planning permit cannot connect to reticulated gas |
| 1 January 2027 | All new residential and commercial buildings must be all-electric |
| 1 March 2027 | Existing homes: gas hot water must be replaced with efficient electric at end-of-life |
| 1 March 2027 | Rental properties: BOTH gas hot water AND gas heaters must be replaced at end-of-life |
The rule does not force anyone to rip out a working system. It triggers only when your existing system fails beyond repair. But if your gas hot water is eight or more years old, the failure window is close.
What "end-of-life" actually means
The ban is not retroactive and it is not forced. It applies at the point when your system fails and replacement is required.
While your system is running: you can keep it, service it, and repair it. None of that changes after 1 March 2027. The rule kicks in when the system is no longer repairable, either because of a catastrophic failure, a safety fault that cannot be economically remedied, or a component that is no longer available.
Gas hot water systems last eight to 12 years on average. If yours was installed before 2015, start planning now. An emergency replacement in January or February 2027 will mean installer queues, potentially higher labour costs, and a much smaller window to apply for rebates before they change.
Can you still repair your gas hot water system after March 2027?
Yes. Repairs to existing gas systems remain permitted. The ban applies only at true end-of-life, when the system requires full replacement.
What's affected, and what isn't
This is where most homeowners get confused. The rules differ significantly depending on your appliance type and whether you're an owner-occupier or a landlord.
| Appliance | Owner-occupier rule | Rental rule (from 1 March 2027) |
|---|---|---|
| Gas hot water system | Must replace with efficient electric at end-of-life | Must replace with efficient electric at end-of-life |
| Gas heater / ducted gas heating | No requirement, can keep indefinitely | Must replace with efficient electric at end-of-life |
| Gas cooktop | No requirement, can keep indefinitely | No requirement |
| LPG (bottled gas) | Like-for-like replacement permitted | Like-for-like replacement permitted |
Owner-occupiers in Cheltenham and across Melbourne South East do not have to touch their gas cooktop or gas ducted heater. The 1 March 2027 rule is specifically about hot water. Landlords face a stricter standard: both gas hot water and gas space heaters must transition to electric alternatives at end-of-life.
Exemptions, who might not have to switch
A small number of situations may qualify for an exemption:
- Heritage properties: applications are assessed case-by-case through Planning Victoria. Approval is not guaranteed, and the process takes time.
- Medical necessity: where a specific appliance is required for a documented clinical reason.
- Technical impossibility: extremely rare in the Melbourne South East context. Most Cheltenham and Bayside homes can accommodate a split-type heat pump outdoor unit with standard clearances.
- LPG connections: LPG (bottled gas) is treated separately from reticulated mains gas. Like-for-like LPG replacements remain permitted.
If you believe you may qualify for an exemption, apply through Planning Victoria and allow several months for the process. Don't assume exemption and wait, have a backup plan.
Why act before March 2027, not after
Consider what happens when your gas hot water system fails in January 2027.
David lives in Mentone. His 11-year-old Rinnai gas storage system fails mid-summer. He needs hot water restored within 24 hours. Every heat pump installer in Melbourne's South East is booked two to three weeks out, the same deadline affects every home in Victoria. Emergency installs attract a premium. The Solar Victoria rebate application process takes longer than one day. David ends up paying full price for a system that, six months earlier, would have cost him less than half as much after rebates.
Acting in 2026 avoids all of this. The rebate stack is confirmed and available now. Helcro's standard lead time is two to four weeks. There is no queue premium, no rebate race, and no risk that income thresholds or rebate amounts change before your installation date.
The current rebate stack is the best it will be. The Solar Victoria income threshold already tightened, dropping from $210,000 to $150,000 on 1 July 2026. Waiting longer means risking further changes.
The Victorian rebate stack, what you can claim
Three separate rebate programs apply to heat pump hot water installation in Victoria. Helcro is a VEU Accredited Supplier (A003039) and a Solar Victoria registered installer, we apply all applicable discounts directly on your invoice. You don't submit forms or wait for a refund.
| Rebate | Amount | Who qualifies | How it's applied |
|---|---|---|---|
| Small-scale Technology Certificates (STCs) | $500–$700 | All Victorian homeowners | Point-of-sale deduction |
| VEU discount | Up to $630 | All Victorian homeowners (no income test) | Point-of-sale deduction |
| Solar Victoria hot water rebate | $1,000–$1,400 | Owner-occupiers, income ≤$150,000/year, property value ≤$3M | Via registered installer |
| Total (income eligible) | Up to $2,700 | ||
| Total (income >$150k/year) | $1,130–$1,330 | STCs + VEU only |
The Solar Victoria rebate is higher for locally manufactured systems (iStore, $1,400) than for other eligible systems (Sanden, $1,000). Your exact rebate depends on which system suits your household.
From 1 July 2026, the Solar Victoria income threshold applies to the combined taxable income of all adult owners of the property, not per person. If the total exceeds $150,000, you still qualify for VEU and STCs.

What does it actually cost after rebates?
Real installed prices vary by system. The following is based on confirmed Helcro pricing and current rebate rates (September 2026):
| System | Installed price | Full rebate stack | Out-of-pocket (income eligible) | Annual saving vs gas |
|---|---|---|---|---|
| iStore 270L heat pump | $2,950 | Up to $2,700 | From ~$250 | $400–$700/year |
| Sanden Eco Plus (split type) | $6,760 | Up to $2,330 | From ~$4,430 | $400–$700/year |
The Sanden Eco Plus qualifies for STCs and VEU ($1,130–$1,330 combined) but attracts the $1,000 Solar Victoria rate rather than the $1,400 locally manufactured rate. The iStore 270L attracts the full $1,400 Solar Victoria rebate as a locally manufactured system.
Running costs for a heat pump are $150–$300 per year versus $600–$1,000 for a gas storage system. The payback period on the iStore, after rebates and running cost savings, can be under two years for households replacing an ageing gas system.
If you already have rooftop solar, the payback is faster. Set your heat pump to run during peak solar hours, typically 10am to 3pm, and the running cost approaches zero on clear days.

Is your Melbourne South East home ready?
This is the section only a local electrician can write. Most Cheltenham, Bayside, and Frankston corridor homes are 1960s to 1990s brick veneer, single-phase, 60A switchboards, standard outdoor access on at least one side.
Switchboard: Heat pump hot water systems draw 1–1.5kW. Most existing single-phase switchboards in Melbourne South East handle this without modification. If you're also planning solar, an EV charger, or an air conditioning upgrade in the same period, a switchboard assessment is worth doing as one job, it's more cost-effective than separate visits.
Outdoor space: Split-type systems like the Sanden Eco Plus require an outdoor unit with approximately 500mm clearance on each side. Tight courtyards and narrow side passages sometimes need siting advice before installation. We assess this as part of every free quote.
Integrated systems: Helcro installs heat pumps, solar panels, and air conditioning. If you're thinking about the combination, gas-free hot water + solar to run it + reverse cycle to replace your gas heater, we can quote the full package and identify which sequencing makes financial sense for your home.
A well-planned installation in 2026 can set up your home to run on solar-generated electricity almost entirely, with running costs a fraction of what gas costs today. Pair your heat pump with a solar battery and your home can run through the night on clean energy too.
