Three questions decide every electrical job in Perth: who is licensed, what is notifiable, and what happens when something goes wrong. Most homeowners and business owners we talk to have been burned once by getting one of those three wrong, so we thought it was worth writing down how a proper electrical service works in Perth, what the rules require and what to look for before anyone touches your switchboard. This is the same brief we walk our own new clients through when they call our workshop on Alex Wood Drive. If you take one thing away, take the licence check.
Key takeaways
- Only a WA-licensed electrician can carry out fixed-wiring work on your property, and every notifiable job requires a Notice of Completion lodged with EnergySafety.
- A good electrical service covers three streams: residential, commercial and industrial, each with different compliance obligations under AS/NZS 3000.
- Regular RCD safety switch testing and smoke alarm battery changes are the two easiest habits that prevent most household electrical incidents.
- For fault-finding, expect a diagnosis-first approach rather than a fixed quote; faults cannot be priced accurately before they are seen.
- Western Power handles network-side faults up to your point of attachment; a licensed electrician handles everything past that point.
What “electrical service” actually means in Perth WA
Perth WA’s housing stock is one of the most varied in the country: 1920s weatherboards in Mount Lawley, brick-and-tile 1970s builds through the northern corridor, and 2026 land releases in Baldivis. Each vintage carries its own wiring generation, and each generation has its own failure pattern. When we talk about an electrical service, we mean the full loop, design, installation, testing, certification, and maintenance across those different property types.
Our team works across Perth, Byford, Fremantle, Midland and Rockingham on switchboards, lighting, RCDs and three-phase equipment. We also handle fault-finding, test and tag, and compliance certificates. The distinction matters because the licence, the paperwork and the standards shift depending on the work. A downlight swap on a suburban ceiling is not the same job as a switchboard upgrade on a warehouse, and pretending they are is how corners get cut.
For homeowners specifically, we cover the day-to-day patterns in more depth in our guide to common electrical problems in Perthhomes and how a local electrician can help. That page walks through the tripping breakers, flickering lights and dead power points that make up the bulk of residential callouts.
Who is legally allowed to do electrical work in WA?
Only a person holding a current WA Electrician’s Worker Licence, working under an Electrical Contractor’s Licence, can carry out fixed-wiring work in Western Australia. That covers anything hardwired: switchboards, power points, lighting circuits, hot water systems, ceiling fans, oven connections, and RCDs. Building and Energy through EnergySafety WAadministers the rules, and they are not optional.
A second layer exists that most homeowners have never heard of: notifiable work. When any fixed-wiring installation or alteration is completed, the contractor must lodge a Notice of Completion with EnergySafety and provide the property owner with an Electrical Safety Certificate. That paperwork is your proof the work was done by a licensed person and inspected against AS/NZS 3000 Wiring Rules. If a “handyman” or unlicensed mate does the work, you receive no notice and no certificate, and your insurance sits in a very grey area.
When you engage us or any licensed contractor, ask two questions before work starts: What is your EC number? Will I receive an Electrical Safety Certificate on completion? If either answer is fuzzy, keep looking.
The three streams of electrical work, and why they matter
Most Perth WA electrical work falls into one of three streams. Getting the right team for the right stream determines half the outcome.
| Stream | Typical Scope | Compliance Load |
| Residential | Lighting, power points, RCDs, hot water, smoke alarms, renovations | AS/NZS 3000, smoke alarm regulations, RCD requirements |
| Commercial | Office fit-outs, retail lighting, shopfront power, emergency exit lighting | AS/NZS 3000, AS 2293 (emergency lighting), test-and-tag schedules |
| Industrial | Three-phase machinery, warehouse power, motor circuits, factory maintenance | AS/NZS 3000, AS/NZS 3760 (in-service safety), plant-specific standards |
We design, install and maintain power systems for homes, offices, warehouses and shopfronts, so all three streams sit under one roof for our clients. That matters when a Perth business owns their premises: the commercial fit-out, and the residential home behind it can receive support from the same team, with one set of records.
If you are running or building a commercial site, our guide to essential electrical safety tips for commercial businesses walks through the maintenance rhythm most SMEs get wrong. For heavier plant, our page on industrial electrical contractors in Perth covers what a project-managed industrial job looks like.
What should I do if my safety switch keeps tripping?
A safety switch (RCD) that trips repeatedly is telling you something is wrong; do not keep resetting it. First, unplug every appliance on the affected circuit, reset the RCD, and plug appliances back in one at a time. The faulty appliance is usually the last one plugged in before it trips again. If the RCD trips with everything unplugged, the fault is in the wiring itself, and you need a licensed electrician to trace it. A tripping RCD is doing its job; ignoring it is how electrical fires start.
New builds and renovations: getting the electrical design right early
The cheapest time to fix an electrical layout is before the plasterboard goes up. Whether you are building a new home, looking to renovate, or need electrical maintenance, our team can support you and offer solutions that provide long-term results. On a new build we prefer to be in the room at concept stage, not called in after the framer has finished. Data cabling runs, three-phase capacity, EV charger provisions, ceiling fan blocking, and kitchen circuit loading are all decided by decisions made months before anyone thinks about power points.
For construction clients specifically, we have a walk-through on how to work with an electrical company in Perth on a new construction project that covers scheduling, pre-wire timing and the coordination points that either save or cost a builder weeks.
Maintenance: the small habits that prevent the big callouts
Maintenance diverges between residential and commercial paths. In homes, the two habits that prevent most incidents are annual RCD testing (press the T button and the switch should trip immediately) and yearly smoke alarm battery replacement. Even hardwired alarms carry a backup battery. Neither task needs an electrician, yet both get skipped by roughly everyone.
For commercial and industrial sites, maintenance is a scheduled program: test-and-tag on portable appliances, emergency lighting checks every six months under AS 2293, switchboard thermal imaging on a rolling cycle, and RCD trip-time testing. We help business owners design a schedule that fits their site rather than copying a generic template. A cafe in Subiaco does not need the same program as a warehouse in Malaga, and paying for the wrong one is money wasted.
If cost is the driver, our piece on how to lower electricity bills in Perth covers the practical energy-efficiency work that pairs well with a maintenance visit: LED retrofits, standby load audits and switchboard rebalancing.
What to look for when choosing an electrical service in Perth WA
After 40 years in the electrical industry we know the questions that separate a good outcome from a bad one. Use this checklist before you engage anyone:
- Current WA Electrical Contractor’s Licence (EC number visible on quotes, invoices, vehicles)
- Public liability insurance certificate available on request
- Electrical Safety Certificate issued on completion of any fixed-wiring work
- Clear scope in writing before work starts, including what is and is not covered
- A real workshop and real vehicles, not a mobile number and a hi-vis (our fleet of 13 vehicles works out of a permanent workshop)
- Willingness to explain what they are doing and why, rather than “just trust me on this one”
Trust is built on the relationships clients place in us, long-term partnerships, quality of workmanship, and the development of our team. Those are the four things we measure ourselves against, and they are the four things we would suggest you measure any electrical contractor against.
How much do electricians charge per hour in Perth?
Perth rates vary by contractor, licence level and job type, so quoted hourly figures online are often misleading. Our own minimum call-out fee is [pricing on request] + GST for up to 30 minutes on site, which covers arrival, diagnosis and small work. Beyond that, jobs are billed on time and materials or, for defined scopes like a switchboard upgrade, a fixed quote. Fault-finding work cannot be quoted upfront because the cause is unknown until the tradesman is on site.
Where can I find electricians in Perth?
We service the full Perth WA metro area from our workshop on Alex Wood Drive, covering Perth, Byford, Fremantle, Midland, Rockingham and everywhere in between. For a broader search, the Building and Energy public registerlets you verify any WA electrical contractor’s licence before booking. Always cross-check the EC number on a contractor’s quote against that register.
Who can carry out electrical work in WA?
Only a person holding a current WA Electrician’s Worker Licence, working under an Electrical Contractor’s Licence, may carry out fixed-wiring electrical work in Western Australia. Building and Energy enforces this under the Electricity (Licensing) Regulations 1991. Unlicensed electrical work is a criminal offence and voids most home insurance policies. Battery-operated and plug-in appliances are exempt; anything hardwired is not.
Who is the biggest electrical contractor in Perth?
Perth’s electrical market is fragmented, with large tier-one contractors handling major infrastructure, and hundreds of licensed SME contractors covering the residential, commercial and light industrial base. “Biggest” is less useful than “right fit for your job.” A national tier-one is overkill for a switchboard upgrade, and a two-person operation is under-resourced for a warehouse fit-out. Match the contractor’s fleet, workshop and licence scope to the work you actually need done.
Do you provide 24/7 emergency electricians in Perth?
We operate during business hours and prioritise urgent faults for existing clients within that window. For genuine after-hours emergencies where safety is at risk, contact Western Power on 13 13 51 for network faults or emergency services for fire and injury risk. Booking any non-urgent electrical work during business hours gets you the same licensed tradesmen at standard rates, without the emergency premium.
Should I call Western Power or an emergency electrician?
The dividing line is your point of attachment, the connection where the network’s cable meets your property. Faults on the network side (streetlight out, no power to the whole street, cable down, meter box damage from outside) are Western Power on 13 13 51. Faults on your property side (one circuit dead, RCD trips, hot water not working burning smell from a power point) are a licensed electrician. If you are unsure, ask the neighbours; if they have power, the fault is yours.
