A Mackay cafe owner saves $400 by getting a mate to wire in a new commercial fryer. The job looks fine. Six months later there is an electrical fire. The insurance assessor finds the install was done by an unlicensed person. The claim is denied. The cafe owner loses $180,000 in stock, equipment and lost trade, plus a $40,000 fine from the Electrical Safety Office.
This is not a hypothetical. The Queensland ESO has run prosecutions just like this every year for a decade. The fines and consequences are real, and they have grown sharper.
Here is what Mackay business owners need to understand about Queensland electrical licensing, and why the cheapest quote is sometimes the most expensive thing in your building.
What Queensland licensing actually requires
In Queensland, any person performing electrical work must hold a current Queensland Electrical Work Licence issued by the Electrical Safety Office (ESO), part of WorkSafe Queensland. The key categories:
- Electrical Mechanic Licence (unrestricted), often referred to as a “Class A licence”. Allows the holder to perform any electrical installation work.
- Restricted Electrical Licence. Limited to disconnect/reconnect of equipment incidental to a trade (e.g. plumbers, fridge mechanics).
- Electrical Contractor Licence. Required for any business contracting to perform electrical work. The business must employ a Qualified Business Person (QBP) and a Qualified Technical Person (QTP).
The Contractor Licence requires:
- Minimum $5 million public liability insurance, including a $50,000 consumer protection component
- A registered ABN and business name
- QBP and QTP competencies (UEECD0007, UEEEL0030 and related units)
Licences renew every 5 years. Holders must maintain current CPR competency.
The actual penalties for unlicensed work
The Electrical Safety Act 2002 sets the framework, and Queensland courts have applied real penalties. The ESO routinely issues $400 on-the-spot infringement notices for minor breaches and pursues prosecution for repeat or serious breaches.
| Case | Where and when | Penalty |
|---|---|---|
| Individual performing unlicensed electrical work | Maximum under the Act | $40,000 |
| Company performing unlicensed electrical contracting, 19 breaches over 18 months | Cleveland Magistrates Court, March 2022 | $76,000 |
| Council aquatic centre after a worker contacted overhead powerlines | 2023 | $85,000 |
| 4th year apprentice advertising electrical services on Airtasker | Richlands Magistrates Court, August 2023 | $45,000 |
| Rental property owner who replaced a light switch himself | Holland Park Magistrates Court, September 2020 | $400 |
| Unsafe work exposing someone to risk of death or serious injury | Maximum under the Act | $600,000 (individual), $3,000,000 (corporation), up to 5 years imprisonment |
Beyond the fines, there are three quieter costs that hit Mackay businesses harder than the headline number.
Cost 1: Insurance denial
This is the big one. Commercial property and business interruption policies in Australia almost universally exclude losses arising from non-compliant electrical work. If your switchboard fails and burns down a Paget warehouse, the insurer will request the CTC (Certificate of Testing and Compliance) for the last electrical work done on the premises. If the CTC was issued by an unlicensed person, or no CTC exists, the claim can be reduced or denied entirely.
For a $1.2 million Paget industrial shed with $400,000 of equipment, denied insurance is a business-ending event.
Cost 2: Lease and tenancy compliance
Most commercial leases in Mackay require the tenant to maintain electrical installations to AS/NZS 3000 standards, and to provide compliance certificates on request. A landlord finding unlicensed work in their premises can void the lease, refuse renewal, and pursue rectification costs from the tenant.
Cost 3: WorkSafe and worker injury
If a staff member is injured by faulty electrical work on your premises, WorkSafe Queensland will investigate. Unlicensed work found in the chain becomes a contributing factor and you (the PCBU, person conducting a business or undertaking) face primary duty of care charges under the Work Health and Safety Act. Fines escalate quickly and personal liability for directors is possible.
The “I only need a small job” trap
The most common scenario in Mackay is not full unlicensed work. It is partial cuts. Examples we see regularly:
- A handyman wires a new lighting circuit in a cafe fit-out, and the licensed electrician then signs off the whole job (illegal, and the electrician’s licence is at risk too).
- A property owner replaces a light switch themselves in a rental at Slade Point or East Mackay (the Carindale rental case fined $400 is a real precedent).
- A workshop supervisor installs an extension lead “permanently” between two switchboards. This is electrical work and requires a licensed electrician.
- An apprentice doing solo unsupervised work on residential systems. Apprentices in their final year are still apprentices and cannot work unsupervised.
Each of these is a sub-$1,000 saving with five-figure penalty exposure.
How to verify a Mackay electrician is actually licensed
Three minutes of due diligence covers this.
- Go to worksafe.qld.gov.au and use the Electrical Licence Search. Enter the licence number from the quote.
- Check the contractor licence is current, not expired, and listed under the same business name on the quote.
- Ask for the Certificate of Currency for public liability insurance and confirm the policy is current and at least $5 million.
- At completion of the job, the electrician must issue you a Certificate of Testing and Compliance (CTC). Keep it on file. If they do not provide one, the work is not signed off.

What “Class A” licensing actually means in practice
When you see “QLD Class A licensed” on a Mackay tradie’s vehicle or website, that is shorthand for the unrestricted Electrical Mechanic Licence. It means the holder can:
- Perform any electrical installation work, single phase or three phase
- Work on switchboards (up to the applicable Wiring Rules clauses)
- Sign off compliance certificates
- Supervise apprentices
A Class A licence is the baseline you should expect for any non-trivial commercial work. For solar specifically, you also need the installer to hold a current Solar Accreditation Australia (SAA) accreditation for grid-connected PV (GCPV) or grid-connected battery storage (GCBS). SAA replaced the Clean Energy Council (CEC) as the accreditation scheme operator on 29 February 2024, with the legislated transition completed 29 May 2024.
What about owner-builders?
Queensland owner-builder licences cover building work, not electrical work. Even if you are an owner-builder on your own house, electrical work must still be performed by a licensed electrician. The only DIY electrical activities allowed are: changing light bulbs, replacing fuses with the same type, plugging and unplugging appliances. That is it.
Frequently asked questions
Can I replace a light switch myself in Queensland?
No. Replacing a light switch is electrical work and must be performed by a licensed electrician. A rental property owner in Carindale was fined $400 in the Holland Park Magistrates Court in 2020 for doing exactly this.
What is a Certificate of Testing and Compliance (CTC)?
The compliance certificate a licensed electrician must issue at the completion of electrical work. Keep it on file. Insurers request the CTC for the last electrical work done on the premises when assessing a claim, and if no CTC exists the work is not signed off.
What electrical work can I legally do myself?
Changing light bulbs, replacing fuses with the same type, and plugging and unplugging appliances. That is the entire list, even if you hold a Queensland owner-builder licence for your own house.
How do I check whether an electrician is licensed?
Use the Electrical Licence Search at worksafe.qld.gov.au and enter the licence number from the quote. Confirm the contractor licence is current and listed under the same business name, and ask for a Certificate of Currency showing at least $5 million public liability insurance.
What does a Class A licence actually mean?
It is shorthand for the unrestricted Electrical Mechanic Licence. The holder can perform any electrical installation work, single phase or three phase, work on switchboards, sign off compliance certificates and supervise apprentices.
