How often do tools need test and tag?
There's no single answer — AS/NZS 3760 sets intervals by risk, and the environment your equipment works in matters more than the tool itself. Here's the general guidance by environment, and where to confirm the exact figure for your site.
Typical intervals by environment
| Environment | Examples | Typical interval | Notes |
|---|---|---|---|
| Construction & demolition | Building sites, civil works, renovations | Commonly 3-monthly | Classified a hostile environment — testing is mandatory, not risk-assessed. |
| Manufacturing & factories | Production floors, industrial workshops | Commonly 6-monthly | Interval depends on the specific risk profile of the equipment and environment. |
| Equipment hire & repair | Hired-out tools, items just repaired or serviced | Before each hire or return to service | Tested at the point of handover, not on a fixed calendar. |
| Hospitality & food service | Commercial kitchens, cafes, venues | Commonly 12-monthly | Heat and moisture push this toward more frequent testing than a typical office. |
| Office & light commercial | Standard office equipment, low-risk retail | Often up to 5-yearly, or per risk assessment | Lowest-risk category; some workplaces choose shorter intervals anyway. |
General industry guidance only — always confirm the interval that applies to your specific workplace against the current AS/NZS 3760 standard, your WHS regulator, or a licensed test-and-tag provider.
Why construction sits at the shorter end
Construction and demolition sites are classified as hostile environments under the Harmonised WHS Regulations — conditions like moisture, dust, heat, and physical knocks that make electrical faults both more likely and more dangerous. That's why testing is mandatory there with no risk-assessment step to skip it, and why the typical interval is far shorter than an office. See our what is test and tag guide for the full picture.
Frequently asked questions
Are these intervals a legal requirement?
They’re commonly applied industry intervals, not a single number written into law for every business. The one hard rule is that hostile environments (including construction and demolition) must be tested and tagged — the specific interval and the requirements for other environments come from the current AS/NZS 3760 standard, your state/territory WHS regulator, and your own workplace risk assessment. Always confirm the exact interval for your situation with the current standard or a licensed test-and-tag provider — this page is general guidance, not a substitute for that.
Does the interval change if a tool is used less often?
Not usually — intervals are generally driven by the environment the equipment is used in and the risk of damage, not how many hours it clocked up. A drill used twice a month on a construction site is still in a hostile environment for as long as it’s there.
What if I have tools that move between environments?
Use the interval for the highest-risk environment the tool is regularly exposed to. A tool that sometimes goes to site and sometimes stays in the workshop should be tested on the site (shorter) interval.
Can software calculate the due date for me?
Yes — that’s the point of a system over a spreadsheet. SiteWarden rolls the next due date forward automatically whenever a test is logged, so nobody has to remember or recalculate it.

Never calculate a due date by hand again
SiteWarden rolls the next due date forward automatically every time a test is logged, and flags any tool that's overdue before a worker can be handed it.
