No. Plumbing and gasfitting are separate categories of work in NSW. A tradesperson may be authorised for both, but being a plumber does not automatically authorise someone to perform gas work.
What is the difference?
Plumbers work on systems such as water services, sanitary plumbing and drainage, operating under the national plumbing and drainage standard AS/NZS 3500 (which sets the safety rules for water supply pressure, backflow protection, and sanitary drainage falls). Gas fitters work on gas installations, including gas supply pipework, connections and appliances, under the national gas installation standard AS/NZS 5601.1 (which governs safe pipe sizing, ventilation clearances, and pressure testing so gas appliances operate without leak or combustion hazards). The work a person may perform depends on the categories shown on their current NSW licence or certificate.
Gas faults can cause fire, explosion or carbon monoxide poisoning. Do not install, alter, repair or test a gas system yourself; use a tradesperson with the appropriate gasfitting authorisation.
Can one tradesperson do both?
Yes. One person can perform both plumbing and gasfitting work if their NSW credentials cover every part of the job.
For example, installing a gas hot-water system may involve water pipework, gas connections and appliance commissioning. The contractor must hold the relevant authorisation for each part or engage appropriately authorised workers.
“Gas plumber” is an informal term, not a licence category or proof of authorisation.
How to check a contractor’s authorisation
Use the NSW builder and tradesperson licence check before booking. Confirm that:
- the licence or certificate is current;
- its categories cover the specific plumbing or gasfitting work; and
- the record matches the person or business quoting for the job.
If the record is unclear, ask the contractor or NSW Fair Trading to confirm the permitted scope.
What affects the charge?
We do not rely on vague online estimates or teaser "from" rates because plumbing and gas installations differ significantly beneath the surface—two jobs that seem similar from a symptom can require entirely different pipe materials, line sizing, regulator adjustments, or structural access through walls and subfloors. Inspecting your property on site allows our licensed tradespeople to assess the real working conditions and deliver an honest, fixed upfront price before any tools touch your pipes, backed by a $0 call-out on approved work.
Rather than leaving you guessing, our technicians walk you through a clear task breakdown detailing each stage of the work—from diagnostic pressure testing and pipe layout to jointing, component replacement, and issuing a mandatory NSW compliance certificate—so you know every step is completed thoroughly from start to finish.
Fixed Today is an established leader in the Sydney plumbing and gasfitting industry, operating under Building Commission NSW Contractor Licence 305428C and Qualified Supervisor oversight across both plumbing and gas categories. Sydney households have trusted, relied on, and returned to our team across decades (since 2011). When you get in touch, our customer service team asks a few targeted pre-dispatch screening questions about your property's construction—such as whether you have double-brick or timber frame walls, suspended timber floors vs a concrete slab, and whether you are connected to natural gas mains or LPG cylinders—so our service vehicle arrives stocked with certified pipework, digital manometers, and leak-testing instruments. For work involving either or both systems, contact our licensed Sydney gas fitting and plumbing team for consultative, supportive guidance.
