You’ve found a property. You’ve done your research. You book a building and pest inspection through a company that looks professional, has a polished website, and charges a reasonable fee.
The inspector turns up. You get a report. You feel like you’ve covered yourself.
But here’s a question most Sydney buyers never think to ask: was the person who walked through that house actually employed by the company you hired? Are they carrying their own professional indemnity insurance? And if they missed something significant, who exactly are you going to hold accountable?
In Sydney’s building inspection industry, these are not hypothetical questions. They are practical ones that a growing number of buyers are finding out the hard way after they’ve already signed contracts.
The Rise of the Marketplace Model
A model has grown significantly in Australia’s property inspection market over the last several years. Rather than operating an in-house team of inspectors, some companies function more like a booking platform — they take your order, assign the job to someone on their network of independent or subcontracted inspectors, and return a report under their own branding.
On the surface, this looks identical to any other building inspection service. The website is professional. The report format is consistent. The price is competitive, sometimes considerably cheaper than you might expect.
What sits behind it can be quite different.
The inspector who arrives at your property may have no direct employment relationship with the company you booked through. They may be an independent contractor doing jobs for several different platforms on any given week. Their experience, their equipment, and their own insurance situation may vary considerably from one job to the next.
This isn’t unique to building inspections — it’s a model borrowed from the gig economy. And like the gig economy broadly, it transfers risk away from the company and onto the person at the end of the chain: you.
What Professional Indemnity Insurance Actually Covers
Before we go further, it’s worth understanding what professional indemnity insurance is and why it matters when you’re buying a property in NSW.
Professional indemnity insurance protects you — the client — if a building inspector’s error, omission, or negligent assessment causes you financial loss. As insurance specialists Wymark Specialty Insurance Advisors explain: if an inspector misses a significant defect, their professional indemnity cover is what pays for the legal defence, any settlement, and your rectification costs.
Without it, you may win a dispute in theory and collect nothing in practice.
From 1 July 2025, the Design and Building Practitioners Act 2020 (NSW) made professional indemnity insurance mandatory for all registered building practitioners in NSW. This is a meaningful reform — but it applies to the practitioner, not necessarily to a booking platform that sits above them.
Here is where the subcontractor model creates a genuine grey area. If you booked an inspection through a company that dispatched a subcontractor to do the job, and that subcontractor holds their own PI cover, the question becomes: does that policy actually extend to work done on behalf of a third-party platform? Does the platform itself carry PI insurance? And if something was missed, which policy responds — and for how much?
These are questions worth asking before you book, not after something goes wrong.
The Accountability Gap
In NSW, recent case law has clarified how liability works in construction more broadly. The High Court of Australia confirmed in Pafburn Pty Ltd v The Owners – Strata Plan No 84674 that builders and developers cannot shift blame to subcontractors when defects arise. Under the Design and Building Practitioners Act, the duty of care is non-delegable — whoever engaged the subcontractor remains responsible.
That’s clear-cut for builders and developers. Building inspection platforms are a different matter, and the contractual arrangements that some of these companies use can be structured in ways that create genuine uncertainty about who you have a claim against if the inspection misses a $40,000 termite infestation or a structural crack that was visible and accessible on the day.
Some companies are transparent about this. They publish their inspector panel, their insurance arrangements, and their complaints process clearly. Others are not. The difference is something you can ask about directly, and you should.
When booking any building inspection, the questions that protect you are simple:
- Is the person doing the inspection directly employed by this company?
- If not, is the inspector a subcontractor, and under what arrangement?
- Who holds the professional indemnity insurance — the company or the individual inspector?
- What is the policy limit, and is it current?
- If I have a dispute about a missed defect, who do I raise it with?
A company that cannot answer those questions clearly — or whose terms and conditions reveal that liability is heavily limited or redirected — is a company worth thinking twice about.
What “Cheaper” Actually Means in This Industry
Some platforms offer inspection prices well below what a sole operator or in-house inspection firm would charge. The shared-report model — where a single inspection report is sold to multiple buyers of the same property at a lower per-buyer price — is one way this works.
There is logic to this in some contexts. But it also means that the inspector completing the job is being paid less per inspection than they would earn working directly with clients, which creates its own pressures around how much time gets spent on each property.
A pre-purchase building inspection on a typical Sydney house, done properly, takes time. The subfloor needs to be entered where accessible. The roof void needs to be inspected. Every accessible room needs a physical walkthrough. A pest inspection on a property with any timber framing involves sounding, moisture metering, and methodical coverage of high-risk areas. None of that is compatible with running five inspections in a day to make up for lower per-job rates.

The Questions Most Buyers Never Think to Ask
Sydney’s property market moves fast. Between the emotion of finding a place you want, the pressure of auction deadlines, and the sheer cost of making an offer, the building inspection can feel like just another box to tick.
It isn’t. It may be the most consequential piece of due diligence you do before spending a million dollars or more. And the person doing it matters as much as the process.
When you book through Vital Building Inspection, the inspector who arrives is the same person who built their reputation here in Sydney, who carries their own professional indemnity and public liability insurance, and who stands behind the report under their own name. There is no subcontracting layer between you and the person responsible for finding what needs to be found.
That is not how every inspection business in Sydney operates. It’s worth knowing which type you’re booking before you commit.

What to Check Before You Book Any Building Inspector
Regardless of who you use, here are the things worth checking before any pre-purchase inspection in Sydney.
Check the inspector’s qualifications, experience and industry credentials. Unlike some building trades, pre-purchase building inspectors in NSW are not required to hold a specific building inspector licence. However, relevant qualifications, industry memberships and extensive hands-on building experience can provide confidence in the inspector’s ability to identify defects and assess property conditions accurately.
When comparing inspectors, ask about their background, training and experience in construction, building defects and property inspections. An inspector with practical building knowledge and years of industry experience can often provide valuable insights beyond what is visible during a standard inspection.
Ask about their insurance directly. Ask about the inspector’s insurance coverage and ensure they maintain appropriate policies, including professional indemnity, public liability, and workers’ compensation insurance where applicable. Reputable inspectors should be able to confirm they hold the necessary cover to protect both themselves and their clients.
If you have concerns about a potential claim, discuss the matter directly with the inspector first. In most cases, any valid claim will be assessed and managed through the inspector, who can then liaise with their insurer if required. This ensures the matter is handled appropriately and through the correct process.
Understand who the report is with. When a dispute arises, you need to know whether your contract is with the company who took your booking or the inspector who did the job. In some arrangements, the platform’s terms and conditions limit their own liability considerably. Read them.
Ask how long the inspection takes. A thorough inspection of a standard three-bedroom house in Sydney with subfloor and roof void access takes upwards of two hours. If the quoted time is significantly less than that, ask why.
Find out what tools they use. A proper inspection in Sydney should include more than a visual walk-through. Sounding equipment, a moisture meter, and thermal imaging used by someone who understands its limitations are all part of a complete assessment. Ask what they bring and how they use it.
It’s a Big Purchase. Act Accordingly.
Sydney’s median house price means that even a modest property represents a substantial commitment. The defects that get missed in a rushed or underresourced inspection — a termite nest in the subfloor, rising damp behind a freshly painted wall, a roof structure with storm damage that wasn’t worth disclosing — don’t become your problem until settlement. After that, they’re entirely yours.
The right building inspector is not necessarily the cheapest one, or the one with the most polished booking platform. It’s the one who turns up, does the job thoroughly, puts their name on the report, and can be held to account if something is missed.
That’s a standard worth holding to.
