What Perth homeowners need to know before installing gas appliances
Renovating your kitchen or upgrading appliances is exciting — new cooktops, modern ovens, better efficiency. But when gas is involved, it’s not something to treat casually. Gas Appliance Installation must be done correctly, legally, and safely to protect your home and everyone in it.
Whether you’re planning a full kitchen renovation or simply swapping out an old gas appliance, this guide breaks down the essentials Perth homeowners need to know without the technical jargon.
1. What Counts as Gas Appliance Installation?
Gas appliance installation covers more than just plugging in a new cooktop.
It includes:
- Installing gas cooktops, ovens, and ranges
- Connecting gas hot water systems
- Modifying or extending gas pipework
- Isolating and decommissioning old appliances
- Testing for leaks and compliance
In WA, all gas work must be carried out by a licensed gas fitter. DIY gas connections are illegal and extremely dangerous.
2. Why Gas Installation Matters During Kitchen Renovations
Kitchen renovations often involve layout changes and that’s where gas becomes critical.
Common renovation triggers include:
- Moving cooktops or ovens to new locations
- Installing kitchen islands with gas appliances
- Switching from electric to gas appliances
- Upgrading to larger or higher-output appliances
Even small changes can require new pipework, pressure adjustments, or ventilation upgrades. Ignoring this early in the renovation process can lead to delays, failed inspections, or unsafe installations.
3. Choosing the Right Gas Appliances for Your Home
Not all gas appliances are created equal — and not all are suitable for every home.
Before installation, consider:
- Gas supply capacity (natural gas vs LPG)
- Appliance size and heat output
- Ventilation and clearance requirements
- Energy efficiency ratings
- Manufacturer installation specifications
A licensed plumber can confirm whether your existing gas system can safely support the appliance you’ve chosen.
4. Compliance, Safety, and Legal Requirements in WA
Gas safety regulations in Western Australia are strict and for good reason. Professional Gas Appliance Installation ensures:
- Compliance with WA gas standards
- Correct pipe sizing and pressure
- Secure isolation valves
- Proper ventilation and flue installation
- Full leak testing and certification
Without certification, you may face:
- Insurance issues
- Failed property inspections
- Safety risks to occupants
Compliance isn’t optional — it protects you long after the renovation dust settles.
5. Common Mistakes Homeowners Make With Gas Installations
Gas issues often arise when installation is rushed or overlooked. Common mistakes include:
- Installing appliances before gas rough-in is completed
- Choosing appliances incompatible with gas supply
- Poor coordination between cabinet makers and plumbers
- Failing to allow space for ventilation
- Using unlicensed installers
These mistakes can be costly to fix — especially once cabinetry and benchtops are installed.
6. When Gas Installations Become Emergency Situations
Poor gas work doesn’t always fail immediately — but when it does, it can become urgent fast. Call an emergency plumber immediately if you notice:
- Gas smells
- Hissing sounds near appliances
- Pilot lights going out repeatedly
- Soot marks or discolouration
- Dizziness or headaches indoors
Gas emergencies are not DIY situations. Immediate professional response keeps your household safe.
7. Coordinating Gas Installation With Other Trades
Successful kitchen renovations rely on timing. Gas installation should be planned:
- Before cabinetry is finalised
- After rough-in plumbing is assessed
- In coordination with electricians and builders
- Prior to appliance delivery where possible
Experienced Perth plumbing services help coordinate gas work so everything lines up — reducing delays and rework.
8. Gas Appliance Installation for Existing Homes vs New Builds
Upgrading gas appliances in established homes can be more complex than new builds.
Existing homes may involve:
- Older pipework requiring upgrades
- Limited access behind walls or floors
- Non-compliant legacy installations
That’s why tailored residential plumbing services are essential — every home is different, and safe gas work depends on understanding what’s already there.

FAQs
1. Do I need a licensed plumber for gas appliance installation in Perth?
Yes. All gas appliance installation in Perth must be carried out by a licensed gas fitter under Western Australian law. This ensures the work is safe, compliant, and legally certified.
2. Can I install a gas cooktop myself?
No. DIY gas cooktop installation is illegal in WA and poses serious safety risks, including gas leaks, fire hazards, and carbon monoxide exposure.
3. Should gas installation happen before or after kitchen cabinetry?
Gas rough-in should be completed before cabinetry is finalised. This allows correct appliance positioning, safe access to isolation valves, and compliance with ventilation requirements.
4. What should I do if I smell gas after installation?
Immediately turn off the gas supply, ventilate the area, avoid using electrical switches, and contact an emergency plumber in Perth WA straight away.
5. Can old gas pipework support new gas appliances?
Not always. Older gas pipework may be undersized or non-compliant and often needs upgrading to safely support modern, high-output gas appliances.
