Electrical
There is no do-it-yourself allowance for fixed electrical wiring anywhere in Australia. These answers cover what that actually means in practice, when a switchboard needs upgrading, what safety switches are required, and how to check an electrician's licence in your state.

Questions
- Do I need an electrician to replace a light fitting?Yes. Replacing a hard-wired light fitting is licensed electrical work everywhere in Australia, and there is no do-it-yourself exemption for it in any state or territory.4 sources cited
- What electrical work can I legally do myself in Australia?Only work that connects by a plug and socket. All fixed wiring, anything connected permanently to the mains, is licensed work in every Australian state and territory.4 sources cited
- Does my house need safety switches, and how many?New and altered circuits must be protected by a residual current device under the national wiring rules, but what is required on an existing untouched home varies by state. Several now require them at sale or lease.4 sources cited
- When does a switchboard actually need upgrading?When it has no residual current protection, still uses rewireable ceramic fuses, has no spare capacity for work you are adding, or shows heat damage, not simply because it looks old.3 sources cited
- Why does my circuit breaker keep tripping?A breaker that trips repeatedly is doing its job and reporting a fault. The three usual causes are an overloaded circuit, a faulty appliance, or a genuine wiring fault, and the third needs an electrician.4 sources cited
- Do I need an electrician to install a ceiling fan?Yes. A ceiling fan is hard-wired and usually needs additional mounting support, so it is licensed electrical work everywhere in Australia and often carries a structural element as well.3 sources cited
- Can I install a ceiling fan myself in Australia?No. A ceiling fan connects to fixed wiring and mounts to structure overhead, so installing one is licensed electrical work in every state and territory.4 sources cited
- Do I need an electrician to install an EV charger at home?Yes. A wall-mounted home charger is a hard-wired appliance on a dedicated circuit, which is licensed electrical work, and most distributors also require the connection to be notified.4 sources cited
- What is three phase power and do I need it?Three phase brings three active conductors into the property instead of one, roughly tripling the available capacity. Most Australian homes are single phase and do not need an upgrade unless total demand has outgrown it.4 sources cited
- Do I need an electrician to run power to a shed?Yes. Running a submain to a detached shed or garage is licensed electrical work, and it usually needs its own small switchboard with residual current protection rather than an extension lead.4 sources cited
- Who can install data and phone cabling in Australia?Cabling connected to the telecommunications network must be done by a registered cabler, which is a separate registration from an electrical licence and is regulated federally rather than by the states.3 sources cited
- Are downlights a fire risk, and do they need clearance from insulation?Older halogen downlights run hot and must be kept clear of insulation, which is why many homes have gaps cut in their ceiling insulation. Modern fittings marked as insulation contact rated may be covered.4 sources cited
- How often should a safety switch be tested?Push the test button on each safety switch about every three months. It should cut power immediately, and a device that does not trip on its own test button is not protecting anything.4 sources cited
- What is the difference between a circuit breaker and a safety switch?A circuit breaker protects the wiring from overload and fire. A safety switch protects a person from electric shock. They do different jobs and a board full of breakers may have no shock protection at all.4 sources cited
- Is old electrical wiring in my house dangerous?Rubber and early plastic insulated wiring degrades with age and heat, and cabling installed before about the 1960s is often at the end of its life. The risk is real but it is assessed by inspection, not by the age of the house alone.4 sources cited
- Can I add a power point outside on a patio or deck?Yes, but it is licensed work and an outdoor socket has extra requirements: a weatherproof enclosure rated for the location and residual current protection on the circuit.4 sources cited
- What are the electrical rules around a swimming pool or spa?Electrical work around a pool or spa is governed by defined zones in the wiring rules, all associated circuits require residual current protection, and equipotential bonding of metal parts is usually required.4 sources cited
- Why do my lights flicker or dim when an appliance starts?A brief dip when a large motor starts can be normal, but persistent flickering, or flickering that has recently started, commonly indicates a loose connection and should be investigated rather than lived with.4 sources cited
- Do I need a permit or approval to install a generator at home?A generator that permanently connects to the house wiring requires a changeover switch installed by a licensed electrician, so the generator can never energise the network while the supply is off.4 sources cited
- How do I check if an electrician in NSW is licensed?Search the free NSW licence verification service using the licence number or business name. It shows whether the licence is current, what class it is, and any conditions on it.3 sources cited
- What is a certificate of electrical safety and do I need one?Most electrical work requires the electrician to issue a compliance certificate to the person who paid for the work. Keep it, because it is the document that proves the work was compliant when you sell or claim.4 sources cited
- Is it worth upgrading halogen downlights to LED?Usually yes, and the case is stronger than the running cost saving alone, because sealed LED fittings let ceiling insulation be closed up and remove the heat that made halogen downlights a fire risk.4 sources cited
- Do I need an electrician to move a power point during a renovation?Yes. Relocating a power point means altering fixed wiring, which is licensed work regardless of how short the move is, and it requires a compliance certificate like any other alteration.4 sources cited
- Is it worth adding ceiling insulation to an existing house?Ceiling insulation is usually the highest-return efficiency upgrade in an Australian home, because heat moves through the ceiling faster than through anything else and retrofitting it is comparatively cheap.4 sources cited
- What should I do if I get an electric shock from a tap or appliance?Treat it as an emergency. A tingle from a tap or appliance usually means voltage is present on metalwork that should be at earth potential, and it can become lethal without warning.4 sources cited
- Do smoke alarms have to be hard wired and interconnected?New builds and major renovations require hard-wired, interconnected alarms nationally. What applies to an existing untouched home varies by state, and Queensland has the most demanding retrofit requirement.5 sources cited
- Can I move my switchboard or meter box?Yes, but it involves the electricity distributor as well as an electrician, because the metering equipment and the service connection are theirs, and it is one of the more expensive electrical jobs.5 sources cited
