When it comes to gas appliances in Australia, the terms Type A and Type B come up often—especially if you’re handling installations, servicing, or replacements, all of which require a gas work license . But what exactly qualifies as a Type A gas appliance, and how does it differ from the more complex gas installation work of type b gas appliances under the Gas Safety Act, particularly in commercial or industrial settings?
Whether you’re a homeowner, tradie, tenant, or commercial business owner, understanding these classifications is crucial—not just for compliance and to comply with regulations , but also for maintenance, safety, efficiency, and peace of mind.

What Is a Type A Gas Appliance?
In simple terms, Type A gas appliances are those you’ll commonly find in residential homes and small businesses, while type b gas appliances are used in more complex setting . They’re mass-produced gas devices type , come with manufacturer specifications, and are generally intended for domestic or light commercial use. These appliances type are typically factory-made and tested to meet standardized safety and performance criteria before entering the Australian market.
Examples of Type A Appliances Include:
- Gas cooktops, ovens, and stoves
- Room heaters and gas fireplaces

Type A vs. Type B: What’s the Difference?
The key differences lie in scale, complexity, and application:
- Type A appliances are standardized consumer-grade products designed for everyday use. They’re easier to install and don’t require engineering input for commissioning.
- Type B appliances, on the other hand, are typically large, custom-built or high-capacity systems used in industrial and commercial settings—such as gas turbines, industrial ovens, or large boilers. These require individual certification, specialized installation, and ongoing supervision by qualified engineers or Type B gas technicians.

Installation and Certification: What You Must Know
Under Australian gas safety regulations, only licensed gas fitters can install, test, and certify Type A gas appliances, as a certification scheme exists to ensure safety . DIY gas work isn’t just illegal—it’s dangerous, especially when it comes to gas installation and when you attempt to service appliances yourself .
Each Australian state and territory has a designated regulatory body:
- NSW – Fair Trading NSW
- QLD – Petroleum and Gas Inspectorate
- VIC – Energy Safe Victoria
- WA – Building and Energy (Department of Mines, Industry Regulation and Safety)
- SA – Consumer and Business Services
- TAS, NT, ACT – Equivalent local gas authorities
After installation, gas fitters must provide a Certificate of Compliance (COC) or similar legal document that confirms the work meets all safety, performance standards, and regulatory requirements, as well as being approved by local authoritie .
Why Certification and Approval Matter
Before a Type A appliance can be sold, installed, or legally used in Australia, it must be formally certified through an approved scheme, and display an approval badge. and might require special certification —such as the AGA Certification Scheme or SAI Global.
Certification ensures that:
- The appliance meets strict safety requirements
- It performs reliably under Australian conditions
- It won’t pose a risk of gas leaks, explosions, or carbon monoxide poisoning
Installing a non-certified appliance can lead to:
- Fines or penalties
- Voided manufacturer warranties
- Rejection of insurance claims
- Serious risks to your health and safety
Pro tip: Always check for a compliance label or ask your gas fitter for proof of certification before installation.
Who Can Install and Service Type A Gas Appliances?
Only qualified, licensed gas fitters from a reputable company are legally allowed to handle the installation, servicing, or disconnection of gas appliances in Australia.
These professionals are trained in:
- Appliance suitability assessments
- Leak testing and pressure checks
- Commissioning and performance testing
- Compliance with AS/NZS 5601 (the Australian Standard for gas installations)
Before hiring someone, check their license status via your local regulator’s online database.
Gas Appliance Safety Tips for Every Home or Business
A few simple precautions go a long way in ensuring gas safety:
