Test and tag frequency is set by the environment, not a single rule. AS/NZS 3760 gives different intervals for an office, a kitchen, a workshop and a construction site. How to set the right frequency for your site so you are covered without over-paying.
Test and tag gets sold two wrong ways: too rarely, which leaves you exposed, or too often, which wastes money. Both miss the point of the standard. AS/NZS 3760 sets the testing frequency by environment, so the right interval for an office is not the right interval for a kitchen or a construction site. This guide explains how to set the correct frequency and keep records that actually protect you. It pairs with our commercial electrical work.
Under AS/NZS 3760, how often equipment is tested depends on where it lives and how hard it works. The logic is wear: a lead dragged across a building site is damaged far faster than one under a desk. The standard turns that into intervals.
Set the frequency per area against the standard and every item gets the interval its environment calls for.
The cheap mistake and the expensive mistake are the same mistake: one frequency for the whole site. Test everything as rarely as the office and your kitchen gear is under-tested and unsafe. Test everything as often as the building site and you are paying to retest desk equipment that has not moved. The standard already solved this by tying intervals to risk. Matching them keeps you compliant and stops you over-paying. A provider who quotes a single rate for a mixed site has not read your environment; they have read their own convenience.
We set the test interval per area against AS/NZS 3760 and hand you the register. The cheap provider quotes one blanket frequency and calls it compliance.
Compliance is not the test; it is the evidence. Each item carries a tag showing who tested it and when, and the whole site is captured in a register: every item, its result, its test date and its next due date. If an incident or audit comes, the register is what shows you met your duty. Ask for it as a digital record you keep, not just adhesive tags that fall off in a kitchen. The register is also how you track due dates so nothing lapses between visits.
Test and tag is one strand of keeping a commercial site safe and certifiable. It sits alongside switchboard condition and project compliance, and the same principle runs through all of them: the obligation is to be safe and to prove it. If your site is also due for board work, see what triggers a switchboard upgrade, and for project compliance read the single certifying electrician explained.
Get test and tag right by reading the environment, setting per-area intervals under the standard, and keeping a register you own. That is how you stay covered without paying for tests you do not need.
