Why Gas Fitting Commands Premium Rates
- Specialist licence required: You need a separate gas fitting licence (not just plumbing)
- Higher risk = higher rates: Gas work carries serious safety implications — charge accordingly
- Mandatory compliance: Every gas job requires a compliance certificate (AS/NZS 5601.1)
- Less competition: Fewer plumbers hold gas licences, so you can charge more
