What You’ll Pay — And How Rebates Reduce It
With rising energy prices across Melbourne, upgrading from a gas hot water system to a heat pump is one of the smartest energy decisions homeowners can make in 2026.
If you’re still using gas for hot water, you’re likely paying more than necessary — and missing out on available rebates.
So, how much does it cost to switch, and how much can you actually save?
What Does It Cost to Replace Gas Hot Water with a Heat Pump?
The cost of upgrading from gas to a heat pump hot water system depends on system size, installation complexity, and your home setup.
Typical Price Range (2026)
- System + Installation (Before Rebates):
$3,000 – $6,500 - Most Common System (270L Heat Pump):
$3,200 – $3,800
These systems are ideal for average Melbourne households and provide efficient hot water year-round.
What Will You Actually Pay After Rebates?
This is where the upgrade becomes highly affordable.
Realistic Out-of-Pocket Cost
- After rebates: $1,100 – $2,200 (typical range)
- Some cases: Low upfront cost depending on eligibility
- Average installed cost: $2,200 – $4,500
👉 Important: “Free heat pump” offers are rare. Most installations involve a small customer contribution based on site requirements.

Victorian Energy Upgrades (VEU) program, along with other incentives.
1. VEU Rebate

Why Upgrade from Gas to Heat Pump?
1. Lower Energy Bills
Heat pumps are up to 3x more efficient than traditional systems.
👉 You can save $600–$900 per year on hot water energy costs.
2. Reduce One of Your Biggest Energy Expenses
Hot water accounts for 20–30% of household energy use.
Switching to a heat pump directly cuts a major portion of your electricity or gas bill.
3. Move Away from Gas
Victoria is transitioning toward all-electric homes, with future regulations impacting gas systems.
Upgrading now helps you:
- Avoid future replacement pressure
- Stay ahead of energy policy changes
- Increase property value
What Affects Your Final Installation Cost?
Even with rebates, final pricing depends on:
- System size (200L vs 270L+)
- Electrical upgrades required
- Pipework or relocation needs
- Brand and warranty
- Property layout
👉 This is why quotes vary from home to home.
Real Cost Example (Gas to Heat Pump Upgrade)
| Component | Cost |
|---|---|
| Heat Pump System | $3,500 |
| Installation | Included |
| Total Before Rebates | $3,500 |
| Rebates Applied | -$2,200 |
| Final Cost | ~$1,300 |
“Free Heat Pump” — What’s the Reality?
Some ads promote $0 heat pump installations, but in reality:
- Most homes require a small upfront payment
- Installation conditions affect pricing
- Lower-cost systems may compromise quality
👉 Focus on reliable systems and accredited installers, not just price.
Why 2026 Is the Right Time to Upgrade
- Strong rebate support still available
- STC values reduce each year
- Gas phase-out policies approaching
- Energy prices continue rising
Delaying your upgrade could mean higher costs and fewer incentives later.
