Direct answer: Electrical certification is the legal paperwork confirming electrical work was done safely and meets New Zealand's rules. Under the Electricity (Safety) Regulations 2010, a certificate must be issued for most electrical work. It matters most when you sell, insure, or have high-risk work done like a switchboard upgrade or a solar install.

What is electrical certification?

Electrical certification is a legal document that confirms electrical work or installations have been completed safely and comply with relevant electrical certification requirements in Auckland. It confirms the installation is safe to use and meets the requirements of the law.

There is not one single certificate. The right one depends on the work: how big it is, and how risky. We break the types down below.

Do I need an electrical safety certificate?

Usually yes, if any real electrical work has been done. Yes, electrical certification is often required for both insurance purposes and building code compliance. Many insurers now request electrical certification before providing coverage, especially when dealing with older homes that are being sold.

Here is the plain version. If an electrician installs, alters, or adds to your wiring, that is general or high-risk work, and a certificate must legally be issued for it. If the job is a small like-for-like swap, that is low-risk work, and a certificate is good practice but not always required. Either way, the certificate is your proof the work was done safely and signed off by someone who put their name to it. On our inspection and certification page you can see how we handle this on a job.

"Certification is not just a piece of paper. It is the proof that the work behind your walls was done safely and signed off by someone who put their name to it. The day you sell, or the day you make an insurance claim, that paperwork is what protects you."

Jordan Statham, Registered Electrician and Electrical Inspector, The Conduction Company

What are the types of electrical certificate?

There are different types of electrical certification, each serving a specific purpose depending on the nature of the electrical work.

Energy Work Certificate

Insurers commonly request an Energy Work Certificate, which is a general term for all types of electrical certification. The specific certification required will depend on the type of installation or work completed.

Certificate of Verification (COV)

A Certificate of Verification (COV) may be required in the following cases:

If there are no existing documents and an insurance company requires electrical certification.
If electrical work has been completed but certification from the original installer is not available.
When an installation has been disconnected for more than six months and needs reconnection.
If you believe your installation is unsafe due to age, improper installation, or damage.

Electrical Safety Certificate (ESC)

An Electrical Safety Certificate (ESC) is issued by registered electrical workers for low-risk work such as maintenance, repairs, or replacements. This certification confirms that the work complies with safety standards.

Electrical Certificate of Compliance (COC)

A Certificate of Compliance (COC) is issued for general-risk electrical work such as new installations, alterations, or additions. The COC includes an ESC section, which verifies the safety of the work performed. This combined document is referred to as a COC&ESC.

Electrical Record of Inspection (ROI)

For high-risk electrical work, an additional level of inspection is required. High-risk work includes:

Switchboard upgrades or relocations
Mains supply cabling and earthing
Solar installations
Parallel Generation (such as generator installations)

For these types of work, the electrical worker will issue a combined COC&ESC, and a registered electrical inspector will issue a Record of Inspection (ROI). The ROI is also recorded in Energy Safety's High Risk Database. Both documents are required for high-risk electrical installations.

Energy Meter Inspections (ROI)

Energy meters are provided by the network retailer in collaboration with a Metering Equipment Provider (MEP). For any work involving energy meters, such as installations, relocations, or rewiring, an inspection by a Network Warranted Electrical Inspector (Warranted Person) is required. This ensures that the meter has been installed correctly and has not been tampered with.

What is the difference between an ESC and a CoC?

An ESC covers low-risk work, and a CoC covers general-risk work and includes an ESC inside it. That is the short version. A CoC is the fuller certificate, and for anything beyond a simple swap it is the one you will see.

	Electrical Safety Certificate (ESC)	Certificate of Compliance (CoC)
Covers	Low-risk work: maintenance, repairs, and like-for-like replacements	General-risk work: new installations, alterations, and additions
Confirms	The specific work is electrically safe	The work is safe and complies with the regulations
How it is issued	Can stand alone for low-risk work	Includes an ESC section, so it is issued as a combined CoC and ESC
Required by law	Good practice, not always required for low-risk work	Required for all general-risk work

High-risk work is a step above both. It still gets a CoC and ESC, but a registered Electrical Inspector must also inspect it and issue a Record of Inspection. More on that under who can issue a certificate below.

When must an electrical safety certificate be issued?

A certificate must be issued for all general and high-risk electrical work before that work is treated as complete. By law, any electrical worker who completes work on an electrical installation must issue certification. This certification must be provided to the person or entity that requested the work within 20 working days of the installation's connection. Additionally, the electrical worker is required to keep a copy of the certification for at least seven years and must produce it within 10 working days if requested by relevant parties.

Two extra points worth knowing. Low-risk work, like a straight fitting replacement, can be certified but is not always required to be. And before an installation is switched on, the person connecting it has to be satisfied it is safe and tested, and hold a current certificate for the work. That is why a certificate more than six months old often will not do for a fresh connection.

Who can issue an electrical certificate in NZ?

Only an electrical worker authorised to certify that specific work can issue the certificate. In Auckland, registered certified electricians are responsible for issuing electrical certifications after completing electrical work. The type of certification depends on the complexity and risk of the job. The more complex or risky the work, the higher the qualifications required of the electrical worker to certify it.

High-risk work needs two people, not one: the electrician who does and certifies the work, and a separate registered Electrical Inspector who inspects it and issues the Record of Inspection. This is where The Conduction Company is unusual. Jordan Statham is both a Registered Electrician and a registered Electrical Inspector, so we can carry out and inspect high-risk work like switchboard upgrades and solar in-house, without waiting on an outside inspector. We are also Master Electricians members, with 450+ five-star Google reviews and more than 2,000 clients served.

Can an electrician do a Certificate of Verification (CoV)?

Yes. A suitably registered electrical worker can issue a Certificate of Verification to confirm an existing installation is safe and suitable for continued use. It is the certificate you reach for when the original paperwork is missing, when an insurer needs proof and none exists, or when an installation that has been off supply for more than six months is being reconnected.

One nuance. For some situations, like reconnecting an installation that has been disconnected a long time, the verification has to be done by someone authorised to certify that type of work, not just anyone with a licence. If you are not sure whether your situation needs a fresh certificate, a verification, or a full inspection, talk to us and we will tell you which one you actually need.

How much does electrical certification cost?

As a line on electrical work we carry out, certification is a small admin fee. The Conduction Company charges $39.90 plus GST for it, and across the NZ market the fee usually runs $20 to $40 plus GST. A standalone Certificate of Verification visit, or an independent Record of Inspection on high-risk work, is a fixed $246.87 plus GST, all-inclusive.

We quote on facts, not guesses

Before we give you a price, we carry out a proper assessment of your property and the work that needs certifying. That way you know exactly what you're buying and the total cost, with no surprises. Clear expectations from the outset, start to finish.

What certification actually costs

The estimates below are for standard electrical certification. Final pricing will be confirmed after we assess the job.

What you need	Cost (plus GST)	Notes
Certification as part of a job we do	$39.90 (our fee)	The market usually runs $20 to $40. Covers preparing and logging the certificate for your work.
Standalone Certificate of Verification visit	$246.87, all-inclusive	We are called only to verify existing work. Visual inspection and limited testing across the installation by registered inspectors and electricians. Does not guarantee a certificate is issued (see below).
Independent Record of Inspection (high-risk work)	$246.87	A registered Electrical Inspector inspects high-risk work, such as a switchboard upgrade or solar install, and issues the Record of Inspection. Re-inspection or extra time may apply (see below).

What a Certificate of Verification visit involves

A verification is a check of your electrical system: a basic visual inspection and limited testing across all parts of the installation, carried out by fully registered inspectors and electricians. The $246.87 plus GST fee is fixed, and it is honest to say up front that it does not guarantee a certificate. We cannot know whether certification can be issued until we have inspected the work. There are two outcomes.

The installation is safe and up to code. We issue a Certificate of Verification, also called an Energy Works Certificate, on the day. That is the document insurers and building-code compliance ask for.

Something was installed incorrectly, or has degraded to an unsafe state. We cannot certify it as it stands. Instead we give you a report of the remedial work needed before a certificate can be issued. We can assess and quote that work at the time of the verification. Once it is done, we issue certification for the work we did, plus a Certificate of Verification for the whole installation.

For an independent Record of Inspection on high-risk work, the same $246.87 plus GST applies. Two honest notes. If items are missed and we have to return to site, a re-inspection charge applies. If we wait on site while issues are rectified during the inspection, that extra time may be charged. If you are not sure how your work needs to be completed, reach out before the inspection and we will point you the right way.

If your job is a switchboard upgrade, our switchboard upgrades page covers what is involved and why it counts as high-risk work. For hourly rates and call-out fees in general, our guide on how much an electrician costs breaks it down.

What happens if you don't have an electrical safety certificate?

Nothing happens on day one, and that is exactly why it is a trap. The legal duty to issue and supply the certificate sits with the electrician who did the work, not with you. But if that paperwork is missing, the practical fallout lands on you later, usually at the worst moment.

Insurance. Insurers often ask for certification, especially on older homes and after a claim involving electrical work. If recent work was never certified, an insurer can question whether it was done safely, and that can complicate a claim.
Selling. Buyers, their lawyers, and their insurers frequently ask to see certificates for recent electrical work. Missing paperwork can hold up a settlement while it gets sorted.
Paying to verify it later. If the original certificate cannot be found, you may need a Certificate of Verification to confirm the installation is safe for continued use. That is a cost you carry down the track for work that should already have been certified.
Safety and liability. Uncertified work has never been independently confirmed as safe. If something goes wrong, that gap is a real problem.

If you think work was done on your place without a certificate, the fix is straightforward. Get a registered electrical worker to inspect it and, where it is safe to do so, verify it. We do this often on older Auckland homes where the history is patchy. Get in touch and we will sort it.

Why choose a certified electrician in Auckland?

When seeking electrical certification in Auckland, it's crucial to hire experienced and certified electricians. Certified electricians ensure that all electrical installations meet the required safety standards and comply with regulations. This is particularly important when dealing with electrical certification for home safety and commercial properties.

Certification is not just a formality. It is an essential part of making sure electrical work is safe and compliant. Whether you are a homeowner, a business owner, or a property manager, certified work protects you from liability and keeps your property safe for the long term. If the work is for a workplace, appliance safety matters too, which is where test and tag comes in.

Frequently asked questions

What is the difference between an ESC and a CoC?

An Electrical Safety Certificate (ESC) covers low-risk work like maintenance, repairs, and like-for-like replacements. A Certificate of Compliance (CoC) covers general-risk work like new installations, alterations, and additions, and it includes an ESC section, so it is issued as a combined CoC and ESC. A CoC is the fuller certificate for bigger work.

Who can issue an electrical certificate in NZ?

Only an electrical worker authorised to certify that specific work can issue the certificate, which in practice means a registered, licensed electrician. High-risk work also needs a registered Electrical Inspector to inspect it and issue a Record of Inspection. At The Conduction Company, Jordan Statham is both a Registered Electrician and an Electrical Inspector.

When must an electrical safety certificate be issued?

A certificate must be issued for all general and high-risk electrical work before that work is treated as complete. The electrician who did the work then supplies your copy, usually within 20 working days, and keeps a copy for at least seven years. Low-risk work can be certified too, but it is not always required.

Can an electrician do a Certificate of Verification (CoV)?

Yes. A suitably registered electrical worker can issue a Certificate of Verification to confirm an existing installation is safe and suitable for continued use, for example when the original certificate is missing or an installation is being reconnected after more than six months off supply. Some cases must be certified by someone authorised for that type of work.

Do I need an electrical safety certificate to sell my house?

There is no blanket rule that a house needs an electrical certificate before it can be sold. But any electrical work done on it should have been certified, and buyers, their lawyers, or insurers often ask to see certificates for recent work, especially on older Auckland homes. Missing paperwork can slow down a settlement.

How much does an electrical certificate cost?

When certification is part of work we carry out, it is a small admin fee. The Conduction Company charges $39.90 plus GST, and the NZ market usually runs $20 to $40 plus GST. A standalone Certificate of Verification visit or an independent Record of Inspection on high-risk work is a fixed $246.87 plus GST, all-inclusive. Every total is confirmed after we assess the job.

Does paying for a Certificate of Verification guarantee I get a certificate?

No. A verification visit is a fixed $246.87 plus GST, but it does not guarantee a certificate, because we cannot know until we inspect the work whether it can be certified. If the installation is safe and up to code, we issue the certificate on the day. If not, we give you a report of the remedial work needed first.
