Test and tag insurance is not a single product. When an appliance test and tag technician asks what cover they need, the honest answer is that the work sits across three different insurance types: public liability, professional indemnity, and portable equipment cover. Each responds to a different kind of loss, and none of them substitutes for the others. What follows explains the liability exposure that WHS rules create when you certify equipment as tested, maps that exposure to the cover types that respond to it, and sets out how to verify your own position. No premium figures appear here, because premiums depend on your insurer, your turnover, your state and your claims history, and inventing a number would be worse than useless.
Why certifying equipment as tested creates liability in the first place
The starting point is not insurance law. It is work health and safety law.
SafeWork NSW states that a business or employer, described as a PCBU, must ensure plug-in electrical equipment used in conditions likely to cause damage is regularly inspected and tested by a competent person. Those conditions include moisture, heat, vibration, mechanical damage, corrosive chemicals and dust. That requirement was checked on 15 September 2026.
A competent person, in SafeWork NSW’s definition, is someone who has acquired through training, qualification or experience the knowledge and skills to inspect and test electrical equipment. Safe Work Australia goes further and says a competent person must perform electrical inspections and testing and is usually a licensed or registered electrician or a licensed electrical inspector.
The practical consequence for a test and tag technician is straightforward. When you attach a tag or sign a testing record, you are not merely performing a service. You are creating a document that says, in effect, this item was inspected and tested by a competent person on this date and passed. If that statement turns out to be wrong and someone is injured, the question of who bears the loss starts with you.
SafeWork NSW also sets out what the record must contain. A record of testing must be kept until the equipment is next tested, removed or disposed of, and it must state who tested the item, the test date, the outcome and the next test date. The record may be a tag attached to the equipment. That record is the evidence trail. It is also, in a dispute, the document that ties the outcome to your name.
The three cover types and what each one responds to
business.gov.au describes public liability insurance as covering you if someone dies, is injured or has property damaged because of your negligence. For a test and tag technician, this is the cover that responds when a piece of equipment you passed fails and causes injury or property damage on a client’s site. It is the most commonly discussed cover in this trade, and it is also the one most often assumed to be sufficient on its own.
Professional indemnity insurance is different. business.gov.au says it helps cover the cost of legal action from claims against your professional advice or services, covering mistakes, neglect or breaches of contract that cause a client loss. This is the cover that responds when the claim is not about physical injury but about the quality and accuracy of what you certified. If you tested an item, recorded it as compliant, and a client later argues that your testing was negligent or that your record was wrong, the claim is against your professional service, not against your physical conduct on site.
Portable equipment insurance addresses a third exposure entirely. business.gov.au describes it as covering accidental loss, damage or theft of tools and electrical equipment you take on a job. Test and tag technicians carry test instruments, leads, tags and often a laptop or tablet for recording results. If that kit is stolen from a vehicle or damaged on site, this is the cover that responds.
There is a related product worth distinguishing. business.gov.au says electronic equipment insurance covers electronic items from breakdown, loss or damage at a specific location and does not cover theft. That is a location-based cover, not a mobile one, so it does not replace portable equipment insurance for a technician who moves between sites.
How the WHS duty maps onto each cover type
The reason these three covers matter together, rather than as alternatives, is that the WHS duty creates more than one kind of exposure.
Safe Work Australia says the competent person determines the nature and frequency of testing, and that equipment in higher-risk workplaces usually needs testing at least once every 12 months. That is a professional judgement call. If you set a testing interval that is too long for the conditions, and an item fails in between, the claim against you is about your judgement. That is professional indemnity territory.
Safe Work Australia also says that if you hire out electrical equipment you must ensure a competent person inspects and tests it, and that RCDs, both fixed and portable, must be regularly tested. If you are the person performing that testing for a hire company, your certification is the basis on which the equipment goes back out. An injury downstream traces back to your record. That is where public liability and professional indemnity can both be engaged, depending on how the claim is framed.
SafeWork NSW names AS/NZS 3760, covering in-service safety inspection and testing of electrical equipment and RCDs, and AS/NZS 3012, covering construction and demolition sites, as the relevant Australian standards. Working to a standard is not the same as being insured against failing to meet it, but it is the benchmark against which your work will be measured if a claim arises.
What to check in your own policy before you rely on it
Insurance for an appliance test and tag technician is only useful if the policy actually responds to the work being done. Several points are worth confirming in writing.
First, check whether the policy names test and tag or in-service inspection and testing as an insured activity. A general electrical contracting policy may not automatically extend to third-party testing and certification work.
Second, check whether professional indemnity cover is included or excluded. Many trade-focused policies bundle public liability and portable equipment cover but treat professional services as a separate extension. If your certification work is the core of what you sell, that extension matters.
Third, check the territorial and site conditions. If you work across state lines, or on construction and demolition sites governed by AS/NZS 3012, confirm the policy does not carve those out.
Fourth, check how the policy treats subcontracted work. If you engage another technician to cover jobs, the question of whose cover responds is worth settling before a claim, not after.
business.gov.au also notes that managing your business insurance is an ongoing task rather than a one-off purchase, which is a reasonable way to think about it. Cover that suited a solo operator doing domestic work may not suit the same operator six months later on commercial sites.
Appliance test and tag tools insurance: a separate question from liability
A frequent point of confusion is whether the tools used to perform testing are covered under the same policy as the liability exposure. They are not the same thing.
Appliance test and tag tools insurance, in the sense of cover for the instruments themselves, falls under portable equipment insurance as described by business.gov.au: accidental loss, damage or theft of tools and electrical equipment you take on a job. A public liability policy does not replace a stolen test instrument. A professional indemnity policy does not replace a dropped tag printer.
This matters because the value of a technician’s kit is not trivial, and because a theft can interrupt the ability to work. The two questions, what happens if I cause harm and what happens if my equipment is lost, need separate answers.
How to verify the position for your own circumstances
Nothing in this article is a substitute for reading your own policy or speaking to a qualified adviser about your specific situation. The public sources cited here describe the WHS duties and the general categories of cover. They do not describe your policy.
A practical sequence is to start with the WHS duty that applies to the sites you work on, then list the ways that duty could translate into a claim against you, then check each of those against your policy wording. Where the wording is unclear, ask the insurer or a broker to confirm in writing.
For questions about how a specific policy or coverage decision applies to your business, the appropriate step is to speak with a qualified insurance adviser or broker who can review your circumstances. For the underlying WHS requirements, the relevant regulator’s published guidance is the reference point, and it is worth checking that guidance periodically because it is updated from time to time.
Common questions
Does public liability insurance cover me if a client claims my testing was wrong?
Not necessarily. business.gov.au describes public liability as covering death, injury or property damage caused by your negligence. A claim that your testing record was inaccurate or your judgement was poor is a claim about professional services, which is the territory of professional indemnity insurance.
Do I need professional indemnity if I only do test and tag?
That depends on how your work is characterised and what your clients require. If you certify equipment and your certification is relied upon, the exposure exists. Whether your policy responds is a question for your insurer.
Is my test equipment covered under public liability?
No. Cover for tools and equipment you take on a job is described by business.gov.au under portable equipment insurance, not public liability.
How often does equipment need testing?
Safe Work Australia says the competent person determines the nature and frequency of testing, and that equipment in higher-risk workplaces usually needs testing at least once every 12 months. The specific interval depends on the conditions of use.
What records must be kept?
SafeWork NSW says a record of testing must be kept until the equipment is next tested, removed or disposed of, stating who tested it, the test date, the outcome and the next test date. The record may be a tag attached to the equipment.
