Switching from Gas? Here’s Why Decommissioning Your Old System Matters
Victoria is moving toward an energy-efficient future — and for thousands of homeowners across Melbourne, that means replacing old gas appliances with electric alternatives like reverse cycle air conditioning and hot water heat pumps.
But there’s one step that’s often overlooked in this process: decommissioning your old gas system. Whether you’re upgrading your ducted heating or replacing a gas hot water unit, understanding the role of decommissioning is key — not just for safety and efficiency, but also for accessing government rebates.
What Is Decommissioning?
Decommissioning means permanently disconnecting and rendering your old gas system inoperable. It could involve:
- Disconnecting from the gas meter
- Capping the gas line
- Physically removing or sealing the old unit
It ensures that the old system is no longer contributing to household energy use or emissions — and that’s a crucial factor for government incentive programs.
Why It Matters for VEU Rebates
If you’re upgrading under the Victorian Energy Upgrades (VEU) program, decommissioning may be a requirement to access certain rebates.
For example:
- Replacing a gas ducted heater with a reverse cycle split or ducted system? ➤ You must decommission the gas unit to claim the rebate.
- Installing a heat pump hot water system? ➤ Rebates are higher if replacing a gas or electric resistance system that is decommissioned.
No decommissioning = no (or lower) rebate.
At Climate Green, we make sure your upgrade complies with VEU standards — including certified decommissioning for maximum eligibility.
Energy Efficiency Gains
Beyond rebates, decommissioning your gas system helps you:
- Reduce standby energy losses
- Improve the performance of your new system
- Eliminate the risk of running two systems in parallel
- Remove gas safety concerns from old, rusted or unused units
It’s a cleaner break — and a cleaner home.
Safety & Compliance
Leaving old gas systems connected can pose serious safety hazards:
- Gas leaks from unused lines
- Pressure build-up
- Carbon monoxide risk from unused, unventilated units
Our licensed team ensures all gas work is done in compliance with Victorian Building Authority (VBA) and Energy Safe Victoria standards.
Will I Need a Site Inspection?
Yes — in most cases, a site inspection is required to:
- Verify the condition and location of your current system
- Determine whether gas disconnection and removal are feasible
- Provide an accurate quote with eligible rebates included
