Most businesses get test and tag done because something forced the question. Here are the five triggers — and what each one actually requires of you.

Most maintenance agreements are vague on the things that matter. What a good one specifies, how they're priced, and the questions to ask before signing one.

The electrical condition of a commercial building rarely shows up in a standard property report — but it decides what you'll spend in year one. What to check before you sign.

An overflow pipe that drips, runs, or steams on the roof is telling you something specific — and if it's steaming, it's costing you money every hour. What's electrical, what's plumbing, and what to do now.

One electrician across your whole portfolio, not a different tradesperson per property. Compliance records, tenant coordination and planned maintenance built around how property managers actually work.

A hard-wired EV charger is prescribed electrical work in NZ — it has to be a licensed electrical worker, tested and certified. What the rules actually require and what a portable charger can't do.

Half the house dark and the other half fine is a specific, diagnosable fault — not a total outage. What's likely going on and what to check before an electrician arrives.

An RCD that trips randomly, at night, or with nothing plugged in is telling you something specific. Here's how to read the pattern and when to call.

An old fuse box isn't automatically dangerous, but it usually means no RCD protection and no spare capacity. Here's when it becomes a real problem and what an upgrade costs.

Offices, shops, cafes and clinics don't need an industrial maintenance regime — but they do need one. What's in a scheduled visit, and why it costs less than the breakdowns.

Main switchboards, tenancy boards and who is paying for whose power. How capacity limits show up during a fitout, and what sub-metering solves for building owners.

If your building has a compliance schedule, emergency lighting and other specified systems must be inspected, tested and recorded every year. Here's how the electrical side works.

Commercial kitchens combine heat, water, steam and heavy equipment. What the electrical side involves — load assessment, dedicated circuits, extraction interlock and emergency isolation.
