Electrical Inspections Auckland

When You Need One

When You Need an Electrical Inspection

Five situations come up over and over. If you’re in one of them, you probably need an inspection.

Buying a house. A pre-purchase electrical inspection is settlement protection, and it matters most on older stock, like the homes behind pre-purchase inspections in Glen Eden and pre-purchase inspections in Remuera. Switchboard, wiring, earthing, RCDs (safety switches), all checked before you sign. A written report in your hand changes the conversation at the negotiating table. Worst case you walk. Best case you knock the price down by the cost of the remediation.

You’re a landlord. The Healthy Homes Standards don’t say “get an inspection every 3 years” in those words, but they do require RCD protection and an adequate earth system. A periodic inspection is how you prove it if a tenant ever calls Tenancy Services. Commercial buildings on a BWOF (Building Warrant of Fitness) cycle need the electrical side documented too, and for businesses portable appliance testing is a separate obligation worth staying on top of.

Your insurer asked for one. Older properties, properties after a claim, and properties with a known electrical history all get flagged at renewal from time to time. The insurer wants written evidence the installation is safe, in the format they expect.

The switchboard’s older than you are. Ceramic fuses, no RCDs, a board half rewired in the 80s and never touched since. That’s not a switchboard, that’s a liability. An inspection tells you what’s still safe and what needs to go. From there we can quote a switchboard upgrade if it makes sense.

Something happened. Lightning strike, surge, partial flood, a small fire, a tree through the roof. Anything that could have stressed the wiring. Your insurer might want the inspection, or you might just want to know. Either way we run the tests and tell you what’s intact.

What We Handle

Certificates of Compliance and Electrical Safety Certificates

Most people who ring us about an inspection actually need a certificate. Two different documents, and they aren’t interchangeable.

Certificate of Compliance (CoC). A Licensed Electrical Worker’s formal declaration that prescribed electrical work meets the safety standards and the Building Code, issued under the Electricity (Safety) Regulations 2010. It covers the work that was done, not the whole house. Prescribed work is what the law actually cares about: a new circuit, a switchboard replacement, hot water heating, any change to permanent wiring. If that work happened, a CoC has to be issued and kept.

Electrical Safety Certificate (ESC). Different document, different trigger. An ESC follows testing and inspection of an existing installation, usually because a building consent asked for it. Councils and lawyers use the two terms as if they’re the same and they aren’t. If someone’s told you to produce an electrical certificate, ring us and read out what the request actually says. We’ll tell you which one it is before you pay for the wrong one.

What you get. A signed certificate listing the work scope, the standards applied, the tests performed and the results. Insurers ask for it. Buyers’ lawyers ask for it. Council wants it before signing off a code compliance certificate. We keep records for the regulatory period, so a lost copy can be reissued.

No certificate for work that’s already been done? Common enough. The previous owner used a mate, or the electrician who did it has since wound up the company. We can’t issue a CoC for someone else’s work, because a CoC certifies the person who performed it. What we can do is test the installation as it stands, document what we find, and certify the current state of it. Ring us with what you’ve been asked to produce and we’ll tell you whether testing the existing installation covers it.

Pre-Purchase Electrical Inspection

Pre-purchase is the one with the highest stakes for the shortest job. You’re about to spend hundreds of thousands of dollars. You want to know what’s hiding behind the switchboard cover.

We do a targeted scope: switchboard age and condition, earthing system (modern MEN or older), RCD presence and trip-time on every circuit that has one, visible wiring condition in roof spaces and under floors where accessible, smoke alarm compliance, hot water connection. Anything obvious that suggests unconsented work.

The deliverable is a written report your conveyancer, lender, or insurer can actually use. Plain English, photo evidence, prioritised. We rank findings as safety-critical, code-compliance, or future-replacement. You take it into the negotiation and you decide whether to push for a price adjustment, a vendor remedy, or to walk. We don’t tell you what to do with it. We just tell you what’s there.

Periodic Electrical Inspection

Periodic inspection is the full health check. We work to Section 8 of AS/NZS 3000 (NZ Wiring Rules), which sets out exactly what gets tested and what counts as a pass.

The visual side comes first. Switchboard condition, cable routing, accessory mounting, signs of overheating, anything that looks rough. If the board itself is the concern, a focused switchboard safety inspection on its own is also available. A lot of faults are caught here before a tester is plugged in.

Then the electrical tests. Insulation resistance testing checks whether the cable insulation between live conductors and earth is still intact, which is the test that catches deteriorated rubber-insulated wiring in older Auckland homes. Earth bond (earth continuity) testing checks the property’s earthing system is connected end to end, because an earth path that’s broken somewhere doesn’t actually protect anyone. RCD trip-time testing confirms your safety switches still trip inside the milliseconds they’re meant to. Thermographic scanning under load picks up hot spots at terminations and inside the switchboard, the kind of stuff you can’t see from the outside.

What fails most often in Auckland? Old rubber-insulated wiring with degraded insulation, undersized earthing on properties before the modern MEN system was standardised, RCDs from the 1980s that are way past their service life, and switchboards with mixed-era components nobody documented. These older devices often need circuit breaker upgrades to meet current standards.

Where We Work

Inspections Across Auckland

Auckland’s housing stock is a layer cake of eras, and each one fails in its own way. We’ve inspected enough properties across the city to know what to look for in each.

1950s state houses. Glen Innes, Avondale, Mt Wellington, Te Atatu. Standardised construction, often with original switchboards still in service. Deteriorated rubber-insulated wiring, ceramic fuses, no RCDs, undersized earthing. We see at least one of those four in nearly every inspection of a property this age.

1980s timber-frame subdivisions. West Auckland, the North Shore, Manukau. RCD technology was just becoming mandatory, so many homes have first-generation RCDs that are now well past their service life. The earthing is usually fine. The safety switches often aren’t, and fitting modern RCD safety switches is the usual remedy.

2000s townhouses. Modern PVC cabling, RCBOs or split-load RCD switchboards. Generally tidy installations, but multi-unit developments sometimes have shared neutral or earth issues at the boundary between units that only show up under testing.

Ex-rental flats and converted dwellings. The wildcard. Original installations layered with cheap modifications, additions wired without consent, and switchboards that don’t match the original supply authority connection. These are the inspections that take the longest because we’re untangling 40 years of decisions.

Whichever band yours falls into, we’ll come to you. We’re based in West Auckland and we cover the whole region.

How It Works

What to Expect

Why TAE

Why Auckland Property Owners Choose Us

EWRB-registered and trained to AS/NZS 3000:2018. Every inspection we sign off is performed by an electrician on the EWRB (Electrical Workers Registration Board) public register at kete.mbie.govt.nz. Verifiable. Current. That register is the whole point of EWRB. We do ongoing electrical maintenance for property managers across the city, so we see what actually breaks in Auckland homes, not what the textbook says should.

Reports buyers, lenders and insurers can actually use. Photos, plain English next to the technical detail, ranked findings. No 18-page PDF with the important part buried on page 11. If your insurer wants a Section 8 verification report with the test results listed, or a lender wants buyer-due-diligence evidence, tell us up front and we’ll produce it that way.

Honest scope. We tell you what’s wrong. We don’t tell you what we’d like to sell you. If your switchboard’s fine, we’ll say it’s fine. If you need repairs rather than a full upgrade, we’ll quote repairs. The inspection report and the remediation quote are separate documents, and you decide which work happens.

Do I need a Certificate of Compliance for this job?

If it’s prescribed electrical work, yes, and there’s no discretion in it. Prescribed work covers new circuits, switchboard replacements, hot water installation, and any alteration to permanent wiring. Swapping a light fitting on existing wiring generally isn’t. The grey area is renovations, where moving a couple of power points becomes new circuits once the wall is open. Ask before the work starts rather than after, because the certificate has to come from whoever did the work and you can’t backfill it later.

When does the law actually require an electrical inspection?

Whenever prescribed electrical work is done, the Electricity (Safety) Regulations 2010 require a CoC, which involves testing as part of the certification. Outside of that, the law doesn’t mandate “get a periodic inspection every X years” for residential homes. But Healthy Homes obligations on landlords, BWOF cycles on commercial buildings, and insurance policy conditions on older properties all create practical reasons you need one. Honest answer: if you’re a landlord, an insurer’s chasing you, or you’re buying a house, get one.

What does a pre-purchase electrical inspection cover?

Everything a buyer needs to know before the deposit goes unconditional: the switchboard, the earthing, the RCDs, and any wiring we can physically reach. Findings are ranked, so you can tell at a glance which ones change the deal and which are just future maintenance.

How often should a rental property be inspected?

Healthy Homes doesn’t set a calendar interval, but most property managers we work with do a periodic check every 3 to 5 years on residential rentals, and annually as part of the BWOF if it’s a commercial tenancy. After a tenancy change is also a good time, especially if the outgoing tenants ran heaters off extension leads for a couple of winters. Cheaper to catch it now than after an incident.

What fails most often in Auckland inspections?

Four things, in roughly this order. Rubber-insulated wiring from the 50s and 60s with degraded insulation. Original ceramic-fuse switchboards with no RCDs at all. First-generation RCDs from the 1980s that no longer trip within spec. And undersized earthing on properties wired before the modern MEN system was standardised. Pick almost any property built before 1990 and at least one of those is sitting there waiting to be found.
