Hiring a commercial electrician is a risk call before it is a price call. The wrong choice can leave you with failed inspections or days without power.
Are you licensed for commercial work and how do I check?
Start here.
Every electrician who touches your site must hold a current electrical licence. Ask for the full name on the licence and the licence number. Then look it up yourself on the public licence register for your area. In Sydney, that means checking the NSW Fair Trading licence register. Don’t accept a photo of a card or a number typed on a quote as proof. You’re looking for a live listing that shows the licence is current and covers the work you need.
Being licensed doesn’t necessarily mean someone is ready for commercial sites. A residential electrician can be fully licensed and still be the wrong choice for three-phase power or a commercial switchboard. We’ve seen neat domestic boards that would not cope in a shop or warehouse, where loads are heavier and fault paths are less forgiving. Commercial switchgear demands different fault ratings and test gear, while the paperwork trail is stricter from start to finish.
Ask straight out whether they do commercial work each week or only now and then. Good answers refer to recent commercial sites and speak plainly about three-phase distribution and load balance. Poor answers stay vague and steer the conversation back to price. Membership with Master Electricians Australia isn’t required by law, but it does tell you the company has agreed to extra standards and dispute processes beyond minimum licence rules. If they can’t give you a number you can verify, stop there. No excuse fixes that gap.
What insurance do you hold right now?
Don’t let anyone start work until you’ve seen proof of insurance. Talk is cheap, and your site carries the risk if cover has lapsed.
Ask for a certificate of currency for public liability. For commercial sites, $10M to $20M is normal. Check the dates and make sure the name on the certificate matches the company on the quote. If the names don’t match, ask why before you go further. Then ask about workers compensation. Any company that sends employees to your site must hold current workers compensation cover. In Sydney, this runs through the state scheme for workplace injuries. An uninsured worker who gets hurt on your premises can leave you tangled in claims and facing downtime you didn’t budget for. Keep copies of both certificates with your quote and final invoice because you may need them months later if a defect or injury claim arises.
Many Sydney commercial properties have their own rules. Building managers often ask for copies before granting site access, and landlords may set minimum cover in the lease. Your electrician should know this routine and have PDFs ready to send. If you manage a strata shop or an office with shared access, ask who will liaise with building management so you aren’t left chasing paperwork.
There’s a simple test here. A genuine commercial company sends both certificates within a day without fuss. Delays and excuses give you a fair idea of how the rest of the job will run.
No paper means no start.
Have you done this exact type of commercial job before?
Residential experience doesn’t always translate to commercial work. Commercial sites run heavier loads and require stricter sign-off.
Ask for two recent commercial jobs that match yours in size and type. A shop fit-out isn’t proof that someone can handle a switchboard upgrade. An office lighting swap doesn’t show that they can wire a workshop with three-phase loads. Switchboard and switchgear projects are a useful test because they show whether the electrician can size protection and coordinate shutdowns without putting your neighbours or tenants at risk.
Good answers include detail, photos you can check and contact names you can call. The electrician should be able to describe the switchboard work completed and how the site kept trading during the job. We’ve learned that specifics beat promises every time. You also want someone with relevant local experience. Sydney commercial properties often come with building management rules and landlord conditions. With after-hours access limits and council inspection steps added to the mix, you need someone who has dealt with these requirements before.
Ask who will handle approvals and site inductions. A company that works in commercial premises each week will know the process and have forms ready. One that doesn’t may leave you chasing signatures while the clock runs. If they can’t show similar work, don’t hire on hope. Commercial mistakes cost more than domestic ones and usually take longer to fix.
What is included in your quote and what isn’t?
Vague quotes turn into variations. Fixed, itemised quotes allow you to compare contractors fairly.
Ask for labour and materials to be listed separately, with quantities and brands where they matter. A switchboard price should state the board size and breaker types. A lighting price should state fitting counts and control types. You should be able to place two quotes side by side and see why one is higher. If one lists parts in detail while the other gives rewiring as a single line, you don’t have two comparable prices.
Ask what isn’t included. Hidden cabling faults and after-hours attendance are common exclusions. Access issues in old ceilings may also sit outside the base price, which is fair if stated up front. Ask how variations are priced and approved. Good companies confirm in writing that no extra work will start without your sign-off and a fixed price for the additional work. If you don’t want to run all these checks from scratch for a Sydney site, start by comparing quotes from commercial electricians sydney who already deal with local building managers and landlords each week.
Use that detailed scope as your baseline. Then ask a second company to price the same scope so you aren’t comparing a full renewal with a patch-up. Ask about deposit and final payment timing before you agree. You want milestones tied to visible progress rather than large sums paid before cable is run.
Don’t hire on price alone.
How will you manage safety and compliance on site?
Good safety planning should be visible before tools come out. Ask for the Safe Work Method Statement for your job.
A proper SWMS isn’t a generic form. It identifies the high-risk tasks on your site and the controls for each one. It often covers live testing controls and safe access. If the crew must work near the public or above other trades, that should be detailed too. Ask to see a sample from a past commercial job. A legitimate commercial electrician will already have site-specific templates ready to share and should be able to tailor one for your address within a day. If they brush it off as paperwork for later, treat that as a fail.
Ask which standard they work to. In Australia, the baseline is AS/NZS 3000, often called the Wiring Rules. You don’t need to know the clause numbers. You need to hear the electrician name the standard without prompting and explain how they will meet it on your job. Ask about RCDs and safety switches as well. A quality electrician raises them before you do. They should test existing devices and tell you if circuits serving your staff lack protection. That check can prevent a serious shock, and it shows that they are thinking beyond the quoted task.
Get the paperwork promise in writing. Every job should finish with a Certificate of Electrical Safety. Don’t accept a verbal assurance that the work is compliant. No certificate means no proof, which can cause trouble if you sell or make a claim.
What warranty and paperwork will I get when you finish?
Get the warranty in writing before work starts. Verbal promises mean little once the invoice is paid.
The standard in our trade is 12 months on workmanship, plus the manufacturer warranty on parts. Ask how long each warranty lasts and what triggers a free return. Loose connections and faulty terminations should be covered. Accidental damage and misuse won’t be, which is fair if stated up front. Ask who honours the warranty if the company changes hands or closes a branch. Good companies provide a clear process and contact name, and keep job records so any technician can see what was installed.
Ask what will be included in the handover pack. At minimum, expect the compliance certificate and an itemised invoice that matches the quote. Test sheets should list the circuits tested and note the results. Keep that pack with your lease and insurance files. You’ll need it for audits and for the next electrician who works on the board.
For larger jobs, settle the contact arrangements and schedule in advance. Ask for a single point of contact who answers during work hours and knows your job by name. Ask how the work will be staged to keep your doors open and your team safe. Night shifts and zoned shutdowns cost more up front but can preserve daytime trade. Ask how budget changes will be handled. Variations should be priced and approved in writing before extra work starts. You should never hear about an overrun after the fact.
Who do I call when power fails after hours?
Outages cost you trade. Ask about the response process before you need it.
Ask whether the company provides 24/7 call-outs for commercial faults and what its typical response time is for your area. Good answers give a time band and explain how after-hours calls are triaged. Poor answers tell you to call a mobile number and hope. Find out who answers at 2am, whether it’s a duty electrician or a message service. We’ve found that this distinction often decides whether a switchboard fault is isolated by dawn or drags into the next trading day.
Ask about ongoing testing and maintenance. Under AS/NZS 3760, portable gear in workshops and construction-type areas is often checked every three to six months, while offices and retail premises often run on a twelve-month cycle. Your electrician should set a schedule that fits your risk and keep records for you. Those records matter when an insurer or building manager asks for proof of upkeep. Ask what spares they carry for commercial faults. Having common breakers and RCDs on the van can mean getting power back in one visit. Waiting for parts means a longer shutdown and more lost sales.
If they can’t promise a clear call-out path, keep looking. You need power back, not promises.
Screen carefully before you hire. Licence checks and clear quotes take an hour and can save weeks of pain. The right electrician answers plainly and provides proof without fuss. Hire that company and keep its number where your team can find it.
