Tackling gas appliance installation yourself can save money — but for some jobs, hiring a licensed gas fitter is the smarter and safer choice. This guide weighs up the DIY-versus-professional decision so you know when to pick up the tools and when to pick up the phone.
Jobs you can often DIY
Simple, low-risk tasks are usually fair game for a confident homeowner — minor prep work, small cosmetic fixes and general maintenance. These carry little safety or compliance risk and can genuinely save on labour.
Jobs best left to a professional gas fitter
- Gas appliance installation
- Gas leak detection
- Gas line installation
- Compliance certificates
- Cooktop connections
Anything involving structural work, safety systems or licensed trades should go to a qualified gas fitter. Beyond the safety risk, unlicensed work can void insurance and cause headaches when you sell.
The true cost of DIY
DIY isn't free. Factor in tools, materials, your time, and the cost of fixing mistakes — which often ends up dearer than hiring a pro from the start. A gas fitter brings the right equipment, buys materials at trade prices and gets it done faster.
A simple rule of thumb
If the job is licensable, risks your safety, or you'd be embarrassed to show the result to a buyer — hire a professional gas fitter.
