A Decision That Is Usually Made in a Hurry
Few manufacturers choose an industrial electrical contractor through a considered process. A line goes down, someone remembers a name, the contractor fixes the problem and from then on they are the site’s electricians. Sometimes that works out well. Sometimes a plant discovers two years later that it has no current drawings, no PLC backups and a contractor who cannot support the control system it has just bought.
Choosing deliberately is not difficult. It takes an afternoon of checks and one honest conversation. This guide sets out what to verify, what to ask for and the warning signs that tell you to keep looking.
Start With the Licence
In Queensland, a business needs an electrical contractor licence to perform electrical work for others, whether it trades as a sole trader, a partnership or a company. That requirement comes from the Electrical Safety Act 2002 and it is separate from the electrical work licence held by each individual electrician.
Three details are worth knowing. First, electrical contractor licences are issued for one year, so currency needs checking every year and not only at onboarding. Second, every contractor must nominate a qualified technical person who performs or supervises the electrical work, and a qualified business person. If the technical person leaves the business, the contractor has a problem and so, potentially, do you. Third, the Electrical Safety Office runs a public licence search. Search for the legal entity named on the quote and confirm the licence is active.
Confirm the Insurance
The Electrical Safety Regulation 2026 requires contractors to hold an insurance policy with a limit of indemnity of at least $5,000,000, together with consumer protection insurance of at least $50,000. The policy must extend to liability arising from testing and certifying, faulty design work and incorrect advice.
That is the legal minimum, and it was not written with a high speed production line in mind. Ask for a certificate of currency and consider whether the limit is adequate for the equipment the contractor will be working on. If the work includes design, check that the policy wording reflects it.
Match the Experience to Your Plant
A licence says nothing about what kind of work a contractor is good at. Most of the electrical contracting industry does domestic and commercial work. A much smaller part does industrial work, and a smaller part again knows food and beverage production.
Equipment. Ask what machines they have worked on. Fillers, seamers, cappers, labellers, palletisers and CIP systems each have their own habits. A contractor who has seen yours before diagnoses faster.
Control platforms. Ask which PLC and drive platforms their people are trained on, and whether they hold the software to go online. A contractor who cannot connect to your controller can only swap parts and hope.
Hygiene and food safety. Ask how they work in a production area: tool control, cable gland selection, enclosure ratings for washdown, and what they do with swarf and offcuts. The answer tells you quickly whether they have done it before.
Machine safety. Ask who assesses and validates a safety function after it has been modified. If the answer is that it gets tested by pressing the emergency stop, keep looking.
Ask How They Handle Live Work
In Queensland, electrical work on or near energised equipment is generally prohibited. The exceptions are narrow: where it is necessary for health and safety, where the equipment must be energised for the work to be carried out properly, where testing is needed to determine whether equipment is energised, and where there is no reasonable alternative. Even then the contractor must carry out a risk assessment, work to a safe work method statement and consult the person who manages or controls the workplace, which is you.
A contractor’s answer to this question is a good guide to its culture. You are looking for a clear isolation procedure, a described process for energised fault finding and a willingness to say no to a production supervisor. You are also looking for evidence that they will involve you, because the regulation expects them to.
Look at What They Hand Over
Ask for a sample handover pack from a recent job. A contractor who takes documentation seriously will have one to hand. It should include the following.
Certificates. A certificate of testing and compliance for installation work, or a certificate of testing and safety for work on equipment. The contractor must give these to the person the work was done for and must keep its own copy for at least five years.
Drawings. New electrical drawings for new work and marked up or redrawn as-builts for modifications. Drawings that do not match the panel are worse than none.
Software. Backups of every PLC, HMI and drive parameter set that was changed, with a note of what changed and why.
Test records. Insulation resistance, earth continuity, safety function tests and anything else that proves the work was verified.
Test the After Hours Promise
Every contractor’s website says 24/7. Find out what it means. Who answers at two in the morning, a tradesperson or a call centre? How many electricians are on the roster? Where do they travel from? What happens when two customers call at once? Ask for an honest response time to your suburb and not a best case.
If your plant runs continuously, a callout arrangement may not be enough. Rostered shift cover or a guaranteed on call arrangement costs more and removes the uncertainty.
One Contractor or Several
Many faults on a production line are not purely electrical. A jammed conveyor trips an overload. A worn change part causes a sensor to miss. A failed bearing overheats a motor. If your electrical contractor has to stop and wait for a fitter from another business, you pay for both of them to stand around.
A contractor with in-house mechanical trades, machining and automation engineers can finish the job in one visit. It also removes the argument about whose fault the problem is.
Seven Warning Signs
No written quote or scope for anything beyond a callout. Reluctance to provide a licence number or certificate of currency. No certificate issued after the last job. A different face every visit. No questions about isolation or site rules on arrival. Modifications made to a PLC program without a backup being taken first. And a habit of resetting a fault and leaving without finding out why it happened.
Any one of these is worth a conversation. Several together are a reason to change.
A Practical Way to Decide
Shortlist two or three contractors. Run the licence and insurance checks. Walk each of them through the plant and listen to the questions they ask, because good contractors ask a lot. Then give your preferred choice a small planned job, such as an audit of one line or a set of drawings for one machine, and judge them on the result before the next breakdown forces the decision.
