Hiring a Electrician in Thornleigh

Before hiring any electrician in Thornleigh, use this checklist to protect yourself and ensure you're working with a properly licensed and insured professional.

  1. Confirm their electrical licence class covers your job — Electrical licences come in different classes. An Electrical Mechanic (or equivalent) licence covers general installation work, while a Restricted Electrical Licence only permits specific tasks like air-conditioning disconnect/reconnect. Always confirm the class matches the work you need.
  2. Ask whether they will test and tag after installation — After completing electrical work, a licensed electrician should perform insulation resistance, polarity, and earth continuity tests. Ask whether testing is included in the quote and whether you will receive a copy of the test results alongside the certificate of compliance.
  3. Check they are registered with the state electrical safety regulator — Unlike most trades where a single building authority issues licences, electricians are often regulated by a separate electrical safety office. Search the relevant state register — such as the QLD Electrical Safety Office or Energy Safe Victoria — to verify the licence is current.
  4. Ask about their approach to switchboard capacity — If you are adding circuits — for a hot tub, EV charger, or workshop — the switchboard may need upgrading. A good electrician will assess spare capacity before quoting and let you know if a switchboard upgrade is required, rather than discovering it mid-job.
  5. Verify they carry a current Electrical Work Licence — In addition to their trade qualification, electricians in most states must hold a current Electrical Work Licence (or Electrician Licence) that is renewed periodically. An expired licence means they are not legally permitted to do electrical work, even if their qualifications are valid.
Pro Tip

Get at least three quotes and compare not just price, but response time, warranty on workmanship, and whether the quote includes parts.

Red Flags to Watch For
  • No certificate of electrical safety provided — After completing prescribed electrical work, the electrician must issue a certificate of electrical safety (or equivalent compliance document). This certificate is lodged with the state regulator. If the electrician says they will "sort it out later" or that it is not needed, the work may not be inspected and could be unsafe.
  • Proposes bypassing safety switches to "stop nuisance tripping" — Safety switches (RCDs) that trip frequently indicate a genuine fault — possibly a damaged appliance, moisture ingress, or deteriorating wiring. An electrician who suggests removing or bypassing the RCD rather than diagnosing the root cause is putting your safety at risk.
  • Unable to show a current Electrical Work Licence — An electrician who only shows a trade certificate or apprenticeship completion without a current Electrical Work Licence may not be legally authorised to perform work. The licence is separate from the qualification and must be renewed regularly with the state electrical safety regulator.

Frequently Asked Questions

What is the difference between a safety switch and a circuit breaker?

A circuit breaker protects wiring from overload and short circuits by cutting power when current exceeds the rated capacity. A safety switch (residual current device or RCD) protects people by detecting tiny current leaks — as small as 30 milliamps — and cutting power within milliseconds. Modern Australian switchboards should have safety switches on all circuits, not just power points. If your switchboard only has circuit breakers, ask an electrician about adding RCDs.

Do I need an electrician to install downlights?

Yes. Installing or replacing downlights involves working with fixed wiring and is classified as electrical work in every Australian state. This includes LED downlight retrofits where you are replacing the fitting, not just swapping a globe. A licensed electrician will also ensure the correct clearances from insulation are maintained to prevent fire risk.

How do I know if my switchboard needs upgrading?

Common signs include ceramic fuses instead of circuit breakers, frequent tripping, no safety switches (RCDs), a burning smell near the board, or insufficient capacity for modern appliances like air conditioners and EV chargers. Switchboards older than 25 years almost certainly lack RCDs on all circuits, which is now a requirement in most states for property sales or major renovations.

Can an electrician install a solar system or do I need a separate solar installer?

Solar panel installation requires both a licensed electrician and a Clean Energy Council (CEC) accredited installer to qualify for government rebates. Many electricians hold CEC accreditation, but not all. If your electrician does not have CEC accreditation, they can do the general wiring work but a CEC-accredited installer must design and commission the system for it to be eligible for Small-scale Technology Certificates (STCs).

What electrical work can I legally do myself?

Australian homeowners can change a light globe, replace a plug-top fuse, and plug in portable appliances. Everything else — including changing a power point cover plate in some states, replacing a light switch, or running any new wiring — must be done by a licensed electrician. DIY electrical work is one of the leading causes of house fires in Australia.

How do I verify a electrician's licence in NSW?

You can verify any electrician's licence using TradieVerify's free search tool or directly through the NSW Fair Trading register. Enter the electrician's name or licence number to confirm their licence status, class, and any disciplinary history.
