How to Choose a Licensed Electrician in Adelaide

Most Adelaide homeowners only think hard about "who's doing my electrical work" once — usually after something's already gone wrong: a downlight that's started smoking, a switchboard that needs upgrading before summer, or a renovation that suddenly needs three new circuits. By then it's easy to grab whoever's available fastest. The problem is that electrical work sits in a different category to most trades: get it wrong and the risk isn't a wonky shelf, it's a fire, an electric shock, or an insurance claim that gets knocked back because the work was never properly certified.

We're Voltas Electrical & Airconditioning, a licensed Adelaide electrical and air conditioning team (licences BLD 274739, PGE 265145, AU 61210) with a 5.0★ rating from 116+ Google reviews, serving Adelaide since 2010. We get asked "how do I know you're actually legit" often enough that it's worth writing down properly — not just for us, but as a checklist you can run against any electrician you're considering, us included.

Step 1: Verify the Licence Number on the CBS SA Public Register

In South Australia, electrical work licensing is administered by Consumer and Business Services (CBS SA), not the Office of the Technical Regulator (which handles the separate compliance-certificate system, covered below). Every genuine electrical contractor and worker in the state holds a licence number issued by CBS, and — importantly — that register is free and public.

Here's the practical version of this step:

1. Ask for the licence number before any work is booked in, not after the van is in your driveway.
2. Search it on CBS SA's "Find a licence holder" register at cbs.sa.gov.au — you can search by name or licence number.
3. Confirm the licence is current, not expired, suspended, or attached to conditions that don't match the job (some licences are restricted to specific classes of work).
4. Check the name matches — the person or business actually turning up should be the licence holder, or clearly working under their supervision.

This step alone rules out unlicensed operators, which matters more than it sounds: electrical work carried out by someone without the right licence is both illegal and dangerous, and it typically won't be backed by a valid compliance certificate either.

Step 2: Check They Carry Public Liability Insurance

A current electrical licence doesn't automatically tell you what insurance is behind the person holding it. Before work starts, ask directly: "what public liability insurance do you carry, and can I see evidence of it?" A properly established electrical business will answer this without hesitation and can usually provide a certificate of currency on request.

Why this matters in practice: if something goes wrong during the job — a fire starts, a wall is damaged, a family member is injured — insurance is what stands between "an unfortunate incident" and "a financial disaster on top of it." An electrician working without insurance may still be licensed, but you're the one carrying all the risk if anything goes wrong on site.

Step 3: Ask About a Certificate of Compliance (eCoC) for the Job

This is the step homeowners most often skip, simply because they don't know it exists. In South Australia, a licensed electrician must issue an electronic Certificate of Compliance (eCoC) for most electrical work — a legal document confirming the work was tested, is safe, and meets the current AS/NZS 3000 Wiring Rules. The eCoC system itself is run through the Office of the Technical Regulator (part of the Department for Energy and Mining), and a completed certificate is emailed directly to you once the work is certified.

Practically, ask two things before the job starts: "will this job get an eCoC?", and after it's finished, "can you send me a copy for my records?" Keep it somewhere safe alongside your other property paperwork — it's the document an insurer will ask for if a claim ever touches that circuit or installation later. If an electrician can't or won't provide one for work that requires it, that's a serious red flag, not an oversight to shrug off.

Step 4: Read Genuine Reviews — and Learn to Spot the Fake Ones

Reviews are useful, but only if you're reading real ones. A few practical checks: look at the total number of reviews, not just the star average (a 5.0★ average from four reviews tells you far less than a 5.0★ average from over a hundred); read a handful of the 3- and 4-star reviews specifically, since genuine feedback tends to include some texture rather than uniformly glowing five-line praise; and check whether the business actually responds to reviews, which is a reasonable sign they take feedback seriously rather than just collecting it.

It's also worth asking the electrician directly for a couple of recent local jobs you could ask about — a business confident in its own work has no problem with this. Word of mouth from a neighbour or a local Facebook community group carries real weight in Adelaide's suburbs too, especially for less common jobs like switchboard upgrades or full rewires.

Step 5: Get a Clear, Itemised Quote Before Any Work Starts

A verbal "should be a few hundred bucks, mate" is not a quote — it's a guess, and guesses are how homeowners end up disputing a bill after the fact. Before any work begins, ask for a written quote that itemises labour, materials, and — importantly — what happens if the scope changes once the electrician opens up a switchboard, wall cavity, or roof space and finds something unexpected (this happens often enough in older Adelaide homes that it's a completely normal question to ask upfront, not a sign of distrust).

A genuinely obligation-free, itemised quote costs you nothing to get and nothing to walk away from if it doesn't feel right. If a tradesperson pushes back hard on putting a price in writing, or insists you decide on the spot, that's worth treating as a signal in itself.

Red Flags to Walk Away From

Most of the checklist above is about what to look for. Just as useful is knowing what should make you stop and reconsider entirely. None of these are minor quibbles — any one of them is a legitimate reason to choose someone else.

Why This Matters More in Older Adelaide Suburbs

Suburbs like Norwood, Kensington, and North Adelaide have a large share of homes built well before modern wiring standards existed — think ceramic fuses, ageing circuits, and switchboards that have never been touched since the house was built. Work on properties like these is exactly where an unlicensed or corner-cutting operator does the most damage, because older wiring hides problems a properly licensed, methodical electrician is trained to check for before they become a fire risk. If you're weighing up whether your own switchboard needs attention as part of this, our guide on when to upgrade your switchboard covers the specific warning signs.

The same logic applies to bigger jobs like a full rewire — see our signs your home needs a full rewire article — where the stakes of choosing the wrong tradesperson are considerably higher than a single powerpoint or light fitting.
