Working throughout Hornsby, Hornsby Heights, Asquith, Normanhurst, and the Upper North Shore, we provide expert service for both natural gas and LPG systems, keeping your home or business running efficiently and safely.

What This Guide Covers
This guide explains everything you need to know about gas fitting in Hornsby, including:
- The types of gas fitting services available for homes and businesses
- When to call a licensed gas fitter and what to expect during service
- How our emergency gas services work
- The benefits of professional installation and compliance testing
Who This Is For
This guide is designed for homeowners, landlords, real estate managers, and businesses in Hornsby who rely on gas for heating, cooking, or hot water.
Whether you’re planning a kitchen renovation, upgrading to a gas hot water system, or need a compliance inspection for a rental property, we provide the expertise and fast response you need.
Why Professional Gas Fitting Matters
Gas work isn’t just another plumbing task — it’s highly regulated for safety reasons. Poorly installed gas systems can lead to explosions, carbon monoxide poisoning, and serious fire hazards.
In NSW, only licensed gas fitters can legally carry out gas work. Using an unlicensed operator can void your home insurance and put your property at risk.
At O’Brien Plumbing Hornsby, safety is our top priority. Every job is completed to AS/NZS 5601 standards, pressure tested and certified with full documentation for your peace of mind.
Understanding Gas Fitting Services in Hornsby
Gas fitting includes the installation, maintenance, and repair of all gas systems and appliances — from cooktops and hot water systems to gas heaters and outdoor BBQ points.
We’re licensed to work on both natural gas and LPG systems, and our qualifications include Certificate III in Gas Fitting plus ongoing professional training to stay up to date with evolving NSW safety requirements.
Natural Gas vs LPG Systems
Most properties in Hornsby have access to mains natural gas, which provides convenient, cost-effective energy for cooking, heating, and hot water.
For homes or rural properties without mains access, we also install and maintain LPG systems using bottled or tank storage. These systems require careful regulation and testing to ensure consistent gas pressure and leak-free performance.
Regardless of the energy source, all gas systems must be installed and maintained by a licensed professional to ensure safety and compliance.
Residential & Commercial Gas Fitting
We handle all types of gas fitting projects across Hornsby:
- Residential: Gas cooktops, ovens, heaters, hot water systems, BBQ points, and outdoor kitchens.
- Commercial: Restaurants, office buildings, strata properties, and industrial systems with large-scale gas loads.
Each project is completed to meet compliance, efficiency, and safety standards, with full testing and certification provided on completion.
Benefits of Hiring a Licensed Gas Fitter

- Safety first: Leak-free installations and correct pressure regulation.
