Why insurance matters when hiring a building inspector
A building inspection is only as useful as the person standing behind it. In New Zealand, a building inspector is not the same as a council building consent authority, and they do not replace the need for specialist trades where required. But a good inspector can save you from buying a property with costly hidden problems — provided they are competent, careful, and properly insured.
Insurance is important because inspection reports can influence major decisions: whether you buy, how much you offer, what repairs to budget for, and whether you walk away. If the inspector misses a significant defect, gives poor advice, or causes damage while inspecting, you want to know there is a financial backstop.
That said, insurance is not a guarantee of quality. It is a safety net. You should still check the inspector’s experience, qualifications, sample reports, and references — and get everything in writing.
The main types of insurance a building inspector should carry
Not every sole trader or small inspection business will carry every policy, but a professional building inspector should usually have at least public liability insurance, and in many cases professional indemnity cover as well.
| Type of insurance | What it covers | Why it matters to you | |---|---|---| | Public liability insurance | Injury to people or damage to property caused during the inspection | Protects you if the inspector breaks something or a third party is injured because of their actions | | Professional indemnity insurance | Losses caused by negligent advice, an error in the report, or failure to identify issues | Important if you rely on an incorrect or incomplete inspection report | | Statutory liability insurance | Some defence costs and penalties arising from accidental breaches of certain laws or regulations | Less common, but useful for businesses operating across multiple sites or services | | Personal accident / income protection | The inspector’s own loss of income if they are injured | Doesn’t directly protect you, but can help the business keep operating | | Vehicle insurance | Damage caused by a work vehicle | Relevant if the inspector attends site in a vehicle and parking or access is tight |
For homeowners, the first two are the most important.
Public liability insurance
Public liability insurance is the basic cover you want to see. It can help pay if the inspector accidentally damages your property or someone is injured as a result of their work.
Examples include:
- breaking a ceiling hatch, fixture, or access panel during inspection - damaging flooring or fittings while moving around the home - causing injury to a visitor or occupant through unsafe conduct on site
While a building inspection is usually low-risk compared with physical building work, it still involves moving through roofs, underfloor spaces, ladders, and potentially tight or fragile areas. Accidents do happen.
Professional indemnity insurance
Professional indemnity cover is especially relevant for a building inspector, because the biggest risk is often not physical damage — it is bad advice.
This type of insurance may respond if the inspector:
- overlooks a defect that should have been identified - gives negligent advice in the report - describes an issue incorrectly and you rely on that mistake - fails to meet the standard of care expected of a competent inspector
A missed leak, hidden decay, weathertightness issue, or unsafe alterations can be expensive. In the New Zealand market, where older homes, leaky building legacy issues, and weather exposure are common, this cover matters.
How insurance protects you as the homeowner
Insurance is not there to make the inspector careless — it is there to reduce the financial consequences if something goes wrong.
Here’s how it can help in practice:
- **Repair costs:** If the inspector damages something during the job, liability cover may pay for repairs. - **Claim costs:** If you suffer loss because of a negligent report, professional indemnity insurance may help with compensation and legal defence. - **Dispute resolution:** Some insurers assist with the investigation and negotiation of claims, which can make a difficult situation easier to manage. - **Business continuity:** Well-insured inspectors are often more professional overall, because insurers usually require them to keep records, follow procedures, and manage risk.
Important note: insurance does not mean you automatically win a claim. You will still need to show what was promised, what went wrong, and how you were affected.
What insurance limits are reasonable?
There is no single mandatory insurance amount for building inspectors in New Zealand, because building inspection is not a licensed trade in the same way that electrical work is regulated by the EWRB or plumbing, gasfitting, and drainlaying by the PGDB.
However, you should still ask what level of cover they hold.
As a practical guide, look for:
- **Public liability cover** appropriate for the property value and the risks on site - **Professional indemnity cover** that is large enough to be meaningful if a report error causes major loss
Higher cover is generally sensible for:
- large or high-value homes - pre-purchase inspections on older villas, bungalows, apartments, or renovated homes - inspections that include roofs, roof spaces, subfloor areas, or moisture-related concerns - situations where the report may be used to negotiate a major purchase decision
Don’t focus only on the dollar amount. Also ask whether the policy is current, what exclusions apply, and whether the cover is on a “claims made” basis.
How to confirm the inspector is actually insured
Never assume an inspector is insured just because they say they are. Ask for proof.
What to request
Ask for:
- a current certificate of currency for public liability insurance - a current certificate of currency for professional indemnity insurance - the name of the insurer - the policy number - the expiry date - the cover limit and any exclusions that might matter to your job
If they hesitate or only give vague reassurance, treat that as a warning sign.
What to check on the documents
Make sure the insurance certificate:
- names the business or person you are hiring - is current on the date they will carry out the inspection - covers the correct type of work, such as building inspection or property inspection - has limits that seem appropriate - does not exclude the type of property you own or the type of report you need
If the inspector operates through a company, make sure the legal entity on the insurance matches the entity invoicing you.
Ask direct questions
A good question list is:
- “Do you have both public liability and professional indemnity insurance?” - “Can you send me the current certificates before I confirm the booking?” - “Is your policy on a claims made basis?” - “Are there any exclusions I should know about?” - “Does your cover apply to pre-purchase inspections, methamphetamine testing if offered, and report writing?”
The answers should be straightforward and in writing.
Insurance is important, but it is not the only check you should make
For NZ homeowners, the safest approach is to combine insurance checks with due diligence on competence.
Before hiring, compare at least two or three written quotes and check:
- experience with your property type - sample report quality and detail - whether the inspector belongs to a recognised industry body, if relevant - whether they follow a clear inspection scope - what the report includes and excludes - whether they use thermal imaging, moisture meters, or drone access where appropriate
A cheaper inspection can be a false economy if the report is too shallow to be useful.
Also remember that some issues are outside the scope of a general building inspection and require specialist trades. For example:
- electrical faults should be assessed by a suitably authorised electrician under the EWRB framework - plumbing, gasfitting, and drainlaying issues should be handled by authorised trades under the PGDB regime - building consent questions may need checking with your local council or an independent building professional
If your inspector spots something significant, ask whether they recommend a specialist follow-up.
Red flags that the inspector may not be properly covered
Be cautious if you notice any of these:
- they refuse to provide insurance certificates - they say they are “covered” but cannot explain by what - they only mention vehicle insurance or equipment cover - they do not use written terms and conditions - they avoid giving a sample report - they offer an unusually low fee with no explanation of scope - they push for cash-only payment and little paperwork
Insurance is easiest to verify when the business is organised and transparent.
Questions to ask before you book
Use these questions to protect yourself:
- What does the inspection include, and what is excluded? - Do you carry public liability and professional indemnity insurance? - Can you email me your current insurance certificates? - How long have you been doing inspections in New Zealand? - Have you inspected homes of this age and construction type before? - How quickly will I get the report? - If you miss something important, what is your complaints or claims process?
The responses should help you compare providers on a like-for-like basis.
The takeaway for NZ homeowners
Yes — your building inspector should be insured, and ideally they should have both public liability and professional indemnity cover. Public liability helps if there is accidental damage or injury during the inspection. Professional indemnity is the big one for homeowners, because it can respond if a report error or negligent omission causes you financial loss.
But insurance alone is not enough. Always check credentials, ask for current certificates, read the scope carefully, and get multiple written quotes. A well-insured, experienced inspector is a better bet than someone who simply says, “Don’t worry, I’ve done this for years.”
In a market where homes can be old, weathered, and expensive to repair, a careful inspection backed by proper insurance is one of the smartest pre-purchase decisions you can make.
