How to Start an Electrical Business in Australia

Decide what business you're actually starting

"Electrical business" covers half a dozen businesses that share a trade and almost nothing else. The money, the hours and the gear all change depending on which one you pick, so pick before you spend anything.

• Residential service and maintenance — fault finding, GPOs, fans, switchboards. Lots of small jobs, fast payment, heavy on quoting and travel.
• New residential construction — rough-in and fit-off as a subbie to builders. Bigger tickets, predictable work, but you're on the builder's payment cycle and carrying the exposure that comes with it.
• Commercial and fit-out — longer jobs, progress claims, more paperwork, more people needed on site.
• Specialist work — solar and batteries, EV charging, data and comms, security. Each one carries its own accreditation or registration on top of your electrical licence.

Most sparkies start on residential service work because it turns over fast and you can do it alone. It's also the model with the most admin per dollar earned — twenty jobs a week means twenty quotes, twenty invoices and twenty chances for something to slip. Know that going in.

The licence that lets you contract

This is the part that catches people. Your electrician's licence lets you do electrical work. It does not let you contract for electrical work — that's a separate authorisation, and every state and territory runs its own. Some licence contractors, some register them; the effect is the same either way.

• A worker's ticket isn't a contractor's ticket. In NSW, for example, a qualified supervisor certificate lets you do and sign off the work but not advertise or contract for it — you need a contractor licence for that. Victoria uses registration rather than licensing and calls the result a Registered Electrical Contractor. Same gate, different name.
• Companies need a nominated supervisor. If you trade through a company or partnership, the entity holds the licence and a qualified person is nominated against it. Evidence of insurance is usually part of the application.
• All work has to comply with AS/NZS 3000, the Wiring Rules, and the compliance certificate goes by a different name in each state — a CCEW in NSW, a COES in Victoria.
• The certificate has a deadline. In NSW a CCEW must be submitted within seven days of the test, and from 1 July 2026 only through the online portal — handwritten and PDF forms are no longer accepted. Treat lodging it as part of finishing the job, not as end-of-month paperwork.
• Solar has its own accreditation. Since 2024 the scheme has been run by Solar Accreditation Australia, which took over from the Clean Energy Council — only SAA-accredited designers and installers can create the certificates behind the federal small-scale rebate. A lot of advice online still says CEC; it's out of date.
• Data and comms needs an ACMA cabling registration — Open, Restricted or Lift, depending on the work — with cabling done to AS/CA S009 and a compliance statement issued at the end.
• Some work is notifiable to the network operator or the regulator. Service and switchboard upgrades usually are. Build that lead time into your quotes.

What you'll be spending money on

Setup costs vary so much between sparkies that any headline figure is useless — the bloke who already owns his ute and his testers is starting from a completely different place to the one who doesn't. What doesn't vary is the list of categories. Price each of these for your own situation and you'll have a number that means something.

That last line is the one people skip and the one that kills businesses. You'll buy materials before you get paid for them, and residential clients who pay on the day are the exception rather than the rule. Work out how many weeks of costs you can carry with no money coming in, and don't start until that number is comfortable.

Set your rate before you take the first job

The single most expensive thing you can do in week one is ring a mate and ask what he charges. His ute is paid off, or it isn't; he works from home, or he rents a unit; he has an apprentice, or he doesn't. Whatever number he gives you is priced for his business, not yours.

Build the number from the bottom instead. The income you want, plus every overhead you'll carry whether or not you're on a job, divided by the hours you can genuinely charge for — which is a long way short of the hours you'll work, once quoting, travel and wholesaler runs are taken out. Then add a real margin on top, so the business banks something rather than just paying you a wage.

• Decide early whether you're pricing hourly, per point, or fixed price — most sparkies end up using all three depending on the job.
• Set a callout or minimum charge for service work, or small jobs will quietly run at a loss.
• Price compliance testing and the certificate as a visible line, every time. It's work you must do; don't do it for free.
• Have an after-hours rate worked out before the first 9pm phone call, not during it.

Do this properly once and it feeds every quote you send from then on. Our guide to working out your charge-out rate walks the calculation end to end, including why a 20% markup and a 20% margin are not the same number.

Insurance, safety and the paperwork that protects you

Electrical work carries consequences other trades don't. A bad joint in a roof space can burn a house down years after you've left it, and the paperwork you kept is what stands between you and wearing it.

• Public liability — the cover most clients, builders and licensing authorities will ask to see before you set foot on site.
• Tools and equipment — replacement cover for a van full of gear that's a target every night it's parked on the street.
• Contract works — covers the job itself while it's in progress, and is often a condition of larger contracts.
• Income protection — you are the business. If you can't work for three months, this is what pays the mortgage.
• Workers compensation — required from the moment you have an employee. Rules and premiums vary by state, so go to your state authority for current requirements.

On top of cover, keep the records. Test results, compliance certificates, photos of the board before and after, and a note of anything you found and flagged but weren't asked to fix. That last one has saved more sparkies than any policy.

Getting the first jobs — and keeping them straight

Your first clients are the people who already know you work. Tell every builder, plumber, real estate agent and mate you've got that you've gone out on your own, and tell them specifically what you want — a sparky who says "switchboard upgrades and fault finding in the eastern suburbs" gets referred; one who says "any electrical work" gets forgotten.

1. Claim your Google Business Profile. It's free, and for local service work it does more than a website will in your first year. Fill it out properly, add photos of real jobs, and ask every happy client for a review.
2. Sign-write the ute. It's the cheapest advertising you'll ever buy, and it works hardest when it's parked in the street outside a job you're already doing.
3. Get a trade account open. A wholesaler account gets you better pricing and 30-day terms, which does more for your cash flow than almost anything else in the first year.
4. Quote fast, and follow up. The sparky whose quote lands the same day wins work off the one whose quote lands Sunday night. Most quotes that go quiet just need one follow-up.
5. Invoice the day you finish. Not Sunday. Not at the end of the month. Payment terms start when the invoice is sent, so every day you sit on it is a day added to how long you wait.
