Why electrician insurance matters for homeowners
When you hire an electrician, you’re trusting them with work that can affect your home’s safety, value, and compliance. Even a small job can go wrong if there’s accidental damage, a faulty installation, or an injury on site.
Insurance is one of the clearest signs that a tradesperson takes their business seriously. It won’t replace proper workmanship, but it can help protect you from paying for losses that shouldn’t be yours to cover.
In New Zealand, electrical work is regulated under the **Electricity Act 1992** and the **Electricity (Safety) Regulations 2010**. Electricians carrying out prescribed electrical work must be appropriately licensed through the **Electrical Workers Registration Board (EWRB)**, and many jobs also need a **Certificate of Compliance** or an **Electrical Safety Certificate** depending on the work done. Insurance sits alongside those legal requirements — it is not a substitute for them.
The main types of insurance an electrician should carry
A self-employed electrician or electrical company may carry several kinds of cover. Not every business needs every policy, but the following are the most relevant for homeowners.
| Insurance type | What it covers | Why it matters to you | |---|---|---| | Public liability insurance | Injury to other people or damage to property caused by the electrician’s work or activities | Helps cover accidental damage to your home, belongings, or a visitor’s injury | | Professional indemnity insurance | Financial loss caused by advice, design, or specification errors | Useful if the electrician is designing a solution or advising on a complex job | | Statutory liability insurance | Defence costs and some penalties related to unintentional breaches of laws and regulations | Can help where compliance issues arise during the job | | Tool and equipment cover | Theft or damage to the electrician’s tools and equipment | Less direct for you, but it can help keep a job moving if tools are stolen or damaged | | Contract works insurance | Damage to work in progress or materials on site | Can be relevant on larger renovations or new installs | | Workers’ compensation / employer cover | Injury to employees or subcontractors, depending on structure and policy | Important if a crew is on site and someone is hurt while working at your property |
Public liability insurance is the big one
If you only ask about one policy, ask about **public liability insurance**. This is the cover most homeowners are thinking of when they ask, “Is the electrician insured?”
It may help if the electrician accidentally:
- drills into a water pipe or another service and causes damage - drops a ladder through a skylight or breaks a window - causes a small fire through a wiring fault during the work - leaves a visitor injured due to a site hazard they created
For homeowners, public liability is important because a tradesperson’s mistake can become an expensive repair bill very quickly, particularly in older NZ homes with mixed wiring, retrofit work, or tight access.
Professional indemnity can matter on design-heavy jobs
Not every electrician needs professional indemnity insurance, but it can be useful where the work involves:
- planning or designing a lighting scheme - specifying switchboard upgrades - recommending load management solutions for EV chargers, heat pumps, or kitchen upgrades - advising on complex renovation or commercial-style installations
If a professional recommendation leads to a financial loss, this cover may help with claims arising from advice or design errors rather than physical damage.
What insurance does — and does not — protect the homeowner from
Insurance is helpful, but it has limits. A well-insured electrician is not a guarantee that you won’t face any problems.
It may help cover:
- accidental damage to your home or property - third-party injury linked to the electrician’s work - claims made because of professional mistakes, in some cases - some legal and defence costs if a claim is made against the business
It usually does not cover:
- poor quality workmanship that isn’t a covered insurable event - deliberate damage or dishonest behaviour - pre-existing faults in your home’s wiring or switchboard - issues caused by another contractor - work done without the correct licence or outside the policy terms
That last point matters. If an electrician is not licensed for the work they’re doing, they may be breaching the law and could also jeopardise their insurance cover. As a homeowner, you should always check both the licence and the insurance.
Why this is especially relevant in NZ homes
New Zealand homes often present practical challenges that can increase risk:
- older villas and bungalows may have outdated wiring, mixed cable types, or cramped roof spaces - coastal homes face corrosion and moisture issues - in winter, more heating and higher demand can expose weak points in existing systems - renovations often uncover hidden defects behind walls or under floors - many homeowners are adding EV chargers, induction cooktops, heat pumps, or solar-related equipment, which can require careful load assessment
Because electrical work interacts with other parts of the house, an installation mistake can affect plaster, cabinetry, flooring, insulation, or even neighbouring properties. Insurance helps reduce the financial fallout when something unexpected happens.
How to confirm an electrician is insured
Don’t assume a website logo or a van sign means cover is in place. Ask for confirmation before you accept a quote or booking.
Ask these questions
- Do you have public liability insurance? - What is the cover limit? - Does the policy cover work at residential properties like mine? - Are your subcontractors and employees covered as well? - Can you provide a current certificate of currency or insurance summary? - Does your cover include the specific type of work I’m having done?
A good tradesperson should be comfortable answering these questions clearly.
What to look for in the paperwork
Ask for a copy of the **certificate of currency** or insurer confirmation. Check that it shows:
- the business name matches the name on the quote or invoice - the policy is current for the dates of your project - the policy type is relevant, especially public liability - the cover limit is stated - any exclusions are understandable and don’t obviously rule out your job
If the electrician is operating as a sole trader, make sure the insurance is in their name or covers their trading entity. If they work through a company, the policy should match the company details.
Also check the licence
Insurance and registration are separate. In NZ, electricians must be properly **licensed by the EWRB** to carry out prescribed electrical work.
Before work starts, confirm:
- the electrician’s registration/licence is current - they are licensed for the category of work they’re doing - they will issue the correct paperwork after the job where required
You can ask for their licence number and verify it through the EWRB register.
What level of cover is reasonable?
There’s no single magic number that suits every job, but cover should be meaningful for the size and risk of the work.
For example:
- a minor repair may not need the same cover as a full house rewire - a large renovation or commercial-style residential upgrade usually warrants higher public liability cover - jobs involving expensive finishes, specialist equipment, or multiple subcontractors need extra care
If a tradesperson won’t tell you the cover limit, that’s a red flag. Likewise, if the limit is very low and your job is high value, you may want to compare other quotes.
Why insurance should be part of your quote comparison
When homeowners compare electricians, it’s tempting to focus only on price. But the cheapest quote can become the most expensive if something goes wrong.
Use this checklist when comparing written quotes:
- full business name and contact details - EWRB registration/licence details - what work is included and excluded - materials and labour separated clearly where possible - expected start date and completion timeframe - warranty or workmanship guarantee terms - insurance details, especially public liability cover - any assumptions about access, consent, or existing wiring condition
A clear quote makes it easier to understand what you’re paying for and helps avoid disputes later.
When council consent or other approvals may be needed
Insurance does not replace compliance with other rules. Depending on the project, you may also need local council approvals or other specialist input.
For example:
- major renovations may need a **building consent** from the local council - switchboard upgrades, EV charger installs, or work affecting structural elements may involve other trades or documentation - if the electrician is coordinating with a builder, plumber, or gasfitter, make sure each contractor is properly licensed and insured for their own trade
In NZ, plumbing, gasfitting, and drainlaying are restricted work under the **PGDB**, while electrical work is regulated by the **EWRB**. If your project crosses into more than one trade, check every contractor’s credentials separately.
Red flags that the electrician may not be the right fit
Be cautious if a tradesperson:
- says insurance is “not necessary” or “covered by the customer” - refuses to provide evidence of cover - can’t produce a licence number or current registration details - wants cash only and avoids written quotes - offers to start immediately but won’t confirm paperwork - is vague about who will actually do the work on site
If a contractor is reluctant to provide basic verification, move on and get another quote.
Practical steps for NZ homeowners before work starts
To protect yourself, follow this simple process:
1. Get at least two or three written quotes. 2. Ask for the electrician’s EWRB details and check them. 3. Request proof of current insurance, especially public liability cover. 4. Confirm whether any building consent or other approvals are needed. 5. Make sure the scope, price, and timeframe are written down. 6. Keep copies of emails, quotes, and insurance documents. 7. Don’t pay everything up front unless there’s a clear written agreement.
This is especially useful during busy periods such as pre-summer renovation season or after storm events, when demand for tradespeople can be high and rushed hiring decisions are more likely.
The bottom line
Yes — your electrician should ideally be insured. At minimum, look for current **public liability insurance**, and for more complex jobs, ask whether they also carry professional indemnity and other relevant cover.
Insurance protects you from some of the financial consequences if something goes wrong, but it only works properly when the electrician is also correctly licensed and the job is done within NZ legal requirements. The smartest approach is to compare a few written quotes, check the EWRB registration, and ask for proof of insurance before any work begins.
That small bit of due diligence can save a lot of stress, delay, and unexpected cost later.
