Gas Water Heater: Installation Fee

Certificate of Gas Safety – What Does It Look Like

Gas Water Heater Installation Fee

What the $399 installation fee covers — and why it is the same whether you choose the Licensed Replacement Package or the Heater Swap Only.

What the fee covers

The $399 installation fee covers the physical labour of replacing your gas water heater. This includes:

Safe removal of the existing gas water heater from the wall

Disconnection of all gas, water, and electrical connections to the old unit

Mounting the new gas water heater in position

Reconnection of all gas, water, and electrical services to the new unit

Removal and disposal of the old unit

Delivery of the new unit to your premises

This is the core labour required to swap the heater — regardless of what other works are included in the package.

Why $399?

The $399 reflects the actual cost of deploying a trained technician to your premises with a vehicle, tools, and the replacement unit. It covers the technician’s time on site (typically 2–3 hours), transit to and from the premises, and the overhead of operating a licensed, insured, and compliant operation.

For reference, City Energy charges $450–$600 (excluding GST) for the same physical swap — and their installation does not include any of the compliance works, pipework replacement, or warranties that Homeone’s Licensed Replacement Package provides.

Same fee, different packages

Licensed Replacement Package: $399 installation fee + gas works + plumbing works + electrical works + compliance + warranties = $2,188 total
Heater Swap Only: $399 installation fee + hardware only = hardware + $399 total
The installation fee is the same in both packages because the physical labour to swap the heater is the same. The difference is in the scope of works around it.

The bottom line

The $399 is the cost of a trained technician replacing your gas water heater safely and professionally. It is comparable to City Energy’s $450–$600 installation fee but includes delivery and disposal of the old unit. It is the same fee whether you choose the full Licensed Replacement Package or the Heater Swap Only option.

The installation fee pays for the labour. Everything else on the quotation pays for the materials, compliance, and warranties that make the installation complete.
