If you work on someone else’s property, drive to job sites, or run a trade business in Australia, public liability insurance isn’t optional — it’s the one policy that stands between you and a lawsuit that could end your business overnight.

Whether you’re a sparky rewiring a 1960s terrace in Newtown, a chippy framing a new deck on the Mornington Peninsula, or a plumber fixing a burst pipe in a Brisbane high-rise, the same question hangs over every job: what happens if something goes wrong and it’s your fault?

This guide walks you through exactly what public liability insurance covers for Australian tradies in 2026, what it doesn’t, what you’ll actually pay, and the state-by-state licensing requirements that might make it mandatory before you even pick up your tools.

What is public liability insurance?

Public liability insurance — often just called PL — covers you if your work causes injury to a third party or damage to their property. “Third party” means anyone who isn’t you or your employee: the client whose house you’re working on, the neighbour whose fence your ute backed into, the pedestrian who tripped over your extension lead on the footpath.

It pays for the legal costs of defending a claim against you and any compensation awarded if you’re found liable. Without it, those costs come straight out of your own pocket. And legal costs add up fast — even a straightforward slip-and-trip claim can burn through $20,000 to $50,000 in legal fees before it even gets to court.

PL is typically sold with a limit of indemnity — the maximum amount the insurer will pay for a single claim. For tradies, the standard options are $5 million, $10 million, or $20 million. The right level for you depends on your trade, the type of work you do, and the requirements of the clients and sites you work on.

Why do most trade licences require it?

In every Australian state, your trade licence or registration comes with an insurance condition. Not all trades in all states — but most trades in most states. The logic is straightforward: licensing bodies exist to protect the public, and requiring tradies to carry PL insurance means there’s a financial backstop if something goes wrong.

Here’s how it breaks down by state:

New South Wales — NSW Fair Trading requires most licensed building and trade contractors to hold PL insurance. Under the Home Building Act 1989, contractors doing residential building work valued over $5,000 must have home building compensation cover, and most licensees are also required to carry PL. Electricians under the NSW Electrical Licence are expected to maintain appropriate insurance.

Victoria — The Victorian Building Authority (VBA) mandates that registered building practitioners carry PL insurance. Under the Building Act 1993, plumbing practitioners licensed by the VBA must also hold PL. Electrical contractors registered with Energy Safe Victoria (ESV) have insurance obligations tied to their registration.

Queensland — The Queensland Building and Construction Commission (QBCC) is one of the strictest regulators in the country. Under the Queensland Building and Construction Commission Act 1991, all QBCC licensees must hold PL insurance as a condition of their licence. The QBCC also sets minimum financial requirements that go beyond insurance — you need to prove you have the net tangible assets to back your turnover.

Western Australia — The Building Commission (now part of the Department of Mines, Industry Regulation and Safety) requires registered building contractors to hold PL insurance. Electrical contractors licensed by Building and Energy (WA) have similar requirements.

South Australia — Consumer and Business Services (CBS) administers building and trade licensing. Under the Building Work Contractors Act 1995, licensed building work contractors must have appropriate PL insurance.

Tasmania — The Consumer, Building and Occupational Services (CBOS) requires licensed building practitioners to hold PL insurance as a condition of their licence under the Occupational Licensing Act 2005.

ACT — Access Canberra, under the Construction Occupations (Licensing) Act 2004, requires most licensed construction occupations to hold PL insurance.

Northern Territory — The NT Building Practitioners Board requires registered building contractors to carry PL insurance.

The bottom line: if you hold a trade licence anywhere in Australia, check your licence conditions. There’s a strong chance PL insurance is a condition you agreed to when you got your ticket. Operating without it isn’t just risky — it can mean your licence is at risk too.

What does PL actually cover?

A standard public liability policy for tradies covers:

Property damage — if your work damages the client’s property or a neighbouring property. A tiler drops a box of porcelain tiles onto a $4,000 imported bathtub. An excavator operator nicks a buried gas line. A painter knocks over a tin of paint onto the client’s hardwood floors.

Bodily injury to third parties — if someone other than you or your employee is injured because of your work. A client trips over your tool bag in their hallway. A piece of debris from your roof work hits a passer-by. A neighbour’s child wanders onto the site and gets hurt.

Legal defence costs — the lawyers, court fees, expert reports, and settlement negotiations if a claim is made against you. These are often covered on top of the limit of indemnity, but check your policy wording — some insurers include defence costs within the limit.

Products liability — if something you supplied or installed causes damage or injury after you’ve left the job. You install a hot water system that later leaks and floods the laundry. You build a retaining wall that collapses six months later. Products liability extends your cover to defects that show up down the track.

Care, custody and control — limited cover for client property in your care. You’re storing the client’s furniture in your van while you sand their floors and someone breaks in. Most policies have a sub-limit here — typically $50,000 to $100,000.

What PL doesn’t cover

This is the part most tradies learn the hard way. Public liability is not a “your business messes up, insurance pays” policy. Here’s what it won’t touch:

Faulty workmanship — if the work you did was defective, PL doesn’t cover the cost of redoing it. If you installed a roof that leaks, PL covers the water damage to the client’s ceilings and furniture, but not the cost of pulling the roof off and doing it again. That’s what your own workmanship warranty is for.

Your own tools and equipment — if someone steals your tools from the ute, PL doesn’t cover them. You need a separate tools and equipment policy for that. We cover this in detail in our tools and equipment guide.

Your own injuries — if you fall off a ladder and break your arm, PL doesn’t pay you a cent. That’s workers compensation (if you’re an employee) or personal accident and illness insurance (if you’re a sole trader). See our income protection guide for more on that.

Asbestos-related claims — almost every PL policy in Australia has a blanket asbestos exclusion. If you’re working on a pre-1990 building and disturb asbestos, any resulting claim is on you. This is non-negotiable with mainstream insurers.

Professional advice — if you give design advice, engineering opinions, or certification that turns out to be wrong, PL typically excludes this. You need professional indemnity insurance for that. NSW is actually making PI mandatory for registered design and building practitioners from July 2026 — we cover that in our professional indemnity guide.

Contractual liability — if you sign a contract that makes you liable for things beyond what you’d be liable for under common law, PL generally won’t cover the extra liability you voluntarily took on. Read contracts carefully before you sign.

How much cover do you need? $5M vs $10M vs $20M

Most sole traders and small trade businesses carry $5 million in PL cover as a starting point. It’s the minimum that most commercial clients, body corporates, and shopping centre management will accept before letting you on site. If you only do residential work for private homeowners, $5 million is usually enough.

$10 million is increasingly the standard ask for medium-sized commercial jobs. Office fit-outs, apartment building common areas, government contracts — if you want to bid on these, you’ll likely need $10 million. Some principal contractors require all their subcontractors to carry $10 million regardless of trade.

$20 million is the domain of larger builders, structural engineers, and anyone working on major infrastructure. It’s also common for trades working in high-risk environments like chemical plants, hospitals, or airports. The premium jump from $10 million to $20 million is often smaller than you’d expect — sometimes only $200-$400 extra per year — because the statistical likelihood of a claim that size is very low.

Based on 2025-2026 market quotes for sole traders with $0-$250K turnover, here’s a rough guide to the premium difference between cover levels for a general trade like carpentry or painting:

  • $5 million: $650-$1,200/yr
  • $10 million: $750-$1,450/yr
  • $20 million: $900-$1,800/yr

The extra $200-$600 to go from $5M to $20M is often worth it if you ever want to step up to commercial work. It’s easier to have it than to scramble for a cover increase when a contract lands on your desk.

What does public liability actually cost?

Here’s where it gets real. These are the premium ranges you can expect in 2026 for a sole trader with under $250K annual turnover, clean claims history, working primarily on residential jobs:

Electrician (sole trader): $800-$2,200/yr for $5M cover. The higher end of the range reflects the elevated risk of fire and electrocution claims. Sparkies doing industrial or commercial work pay more.

Plumber (sole trader): $700-$1,900/yr for $5M cover. Water damage claims drive premiums. Gas fitters pay a loading — typically $150-$300 extra.

Carpenter / joiner (sole trader): $650-$1,500/yr for $5M cover. Shop-based joiners pay less than on-site framing carpenters. Structural work pushes premiums up.

Builder (registered, small residential): $1,500-$4,000/yr for $10M cover. Builders almost always need higher limits. Subcontractor management and structural work are the main premium drivers.

Painter (sole trader): $550-$1,100/yr for $5M cover. Among the lowest premiums, but accidental damage to carpets, joinery, and glazing still happens.

Landscaper (sole trader): $600-$1,300/yr for $5M cover. Retaining walls and excavation work increase premiums. Plant and tree damage claims are surprisingly common.

Tiler (sole trader): $600-$1,200/yr for $5M cover. Waterproofing failures and tile delamination claims drive premiums in this trade.

Cleaner (sole trader): $500-$900/yr for $5M cover. Lower risk overall, but damage to client property from chemicals and equipment still produces claims.

These are market-level ranges based on 2025-2026 quotes. Your actual premium depends on your specific trade, turnover, location, claims history, and the insurer’s appetite for your risk profile at the time you apply.

What affects your PL premium?

Seven factors drive your premium up or down:

Your trade — the riskier the activity, the higher the premium. An electrician pays more than a painter. A demolition contractor pays more than an electrician. Insurers have occupation rating tables that assign every trade a risk grade.

Your turnover — higher turnover usually means more projects, more hours on site, more opportunity for something to go wrong. Most insurers band turnover: $0-$50K, $50K-$100K, $100K-$250K, $250K-$500K, and so on.

Your claims history — a clean five-year record is the baseline. One claim and you’ll see a loading. Two claims in three years and some insurers won’t quote at all.

Your location — postcode matters. Working in cyclone-prone North Queensland, bushfire-risk zones, or areas with high crime rates can push premiums up. Some insurers charge a metro loading for Sydney and Melbourne CBD work.

Your subcontractor usage — if you use subbies, you’re responsible for what they do on your job. Insurers want to know how many, what trades, and whether they carry their own PL. Uninsured subbies are a major red flag.

Your contract values — the bigger the individual project, the bigger the potential loss. A tiler doing $5,000 bathroom renos has a different risk profile to one doing $200,000 commercial flooring contracts.

Your risk management — do you have a documented safety system? Do you use written contracts? Do you take site photos before starting work? Some insurers offer discounts for formal risk management practices, but in the tradie market this is still relatively rare.

Do you actually need PL if you’re a sole trader?

A question that comes up a lot: “I’m just a one-man band with an ABN. Nobody employs me. Nobody works for me. Do I really need PL?”

The short answer: almost certainly yes.

First, if you hold a licence, check the conditions. As we covered above, most state licensing bodies require PL as a licence condition. Operating without it puts your licence — and your ability to earn a living — at risk.

Second, even if your licence doesn’t technically require it, any client worth working for will. Private homeowners might not ask, but real estate agents, body corporates, builders, and commercial clients will. Your PL certificate of currency is often the first document they request. No PL means no job.

Third, the risk is real. A single claim — a client trips over your extension lead, your ladder scratches a $60,000 car, your apprentice puts a nail through a water pipe that floods three apartments — can cost more than your annual income. PL costs less than a cup of coffee a day. The maths isn’t complicated.

What’s a certificate of currency and when do you need one?

A certificate of currency is a one-page document from your insurer that proves you have a current PL policy. It shows your name, ABN, the insured amount, the policy number, and the expiry date. Think of it as your insurance rego papers.

You’ll be asked for your certificate of currency when:

  • A builder or principal contractor onboards you as a subcontractor
  • A body corporate or strata manager approves you for work in common areas
  • A real estate agent engages you for maintenance work
  • A commercial client’s procurement system requires vendor documentation
  • Your licensing body audits your compliance

Most insurers let you download your certificate of currency instantly from their online portal. Keep a PDF on your phone and email it on demand. Some platforms — including BizCover — generate certificates automatically when you buy a policy, so you’re never waiting on a broker to send one over.

How does excess work?

The excess is the amount you pay towards a claim before the insurer pays the rest. For tradie PL policies, excess typically ranges from $250 to $2,500. A higher excess means a lower premium, but you need to be comfortable fronting that amount if a claim lands.

Some policies have different excesses for different types of claims. Property damage might carry a $500 excess while bodily injury has a $1,000 excess. Check the schedule — the lowest advertised excess is rarely the one that applies to everything.

One thing to understand: the excess is per claim, not per year. If you have three claims in one year, you pay the excess three times. This is why claims history matters so much to insurers.

How to compare PL quotes

Shopping for PL insurance used to mean calling three brokers, waiting a week for each to come back, and then trying to compare three different policy wordings. In 2026, it’s faster. Online comparison platforms let you enter your details once and see quotes from multiple insurers side by side.

When comparing, look beyond the premium:

  • Limit of indemnity — is it $5M, $10M, or $20M? Make sure you’re comparing like with like
  • Excess — what do you actually pay per claim?
  • Exclusions — does the policy have any unusual exclusions relevant to your trade?
  • Defence costs — are legal costs inside or on top of the limit of indemnity?
  • Retroactive cover — if a claim arises from work you did before the policy started, are you covered?
  • Run-off cover — if you stop trading, does the policy cover claims that arise from past work?
  • Insurer rating — is the underwriter a known name (QBE, Allianz, CGU, Vero, Zurich) with an A+ financial strength rating?

What about BizPack?

Many insurers now offer packaged policies for tradies — sometimes called BizPack, Business Pack, or Tradie Pack — that bundle PL with other covers like tools, personal accident, and business interruption into one policy with one renewal date.

The advantage is convenience and often a discount versus buying each policy separately. A standalone $5M PL policy might cost $900. Add $500 for tools cover and $400 for personal accident — $1,800 total. A BizPack with the same covers might run $1,450-$1,600.

The disadvantage is less flexibility. If you want to switch insurers for one component but not the others, you can’t. If one element of the pack has a claim, the whole pack’s renewal premium might rise.

Whether bundling makes sense depends on your specific needs. We compare standalone vs bundled costs in more detail in our tradie insurance cost guide.

Frequently asked questions

What happens if I don’t have public liability insurance and someone makes a claim?

You’re personally liable for the legal costs and any compensation awarded. For a serious injury claim, that could mean hundreds of thousands of dollars. If you operate through a company structure, the company’s assets are at risk. If you’re a sole trader, your personal assets — including your house — are on the line. Bankruptcy is a real outcome for uninsured tradies who lose a major claim.

Does my PL cover me when I’m working on my own house?

No. Public liability covers claims from third parties — clients, passers-by, neighbours. Work on your own property is not covered because you’re not a third party to yourself. If you’re building your own deck and a neighbour’s property gets damaged, your PL might respond. But damage to your own property or injury to yourself is outside the policy.

Can I get PL cover for a one-off job or do I need an annual policy?

Annual policies are the standard and almost always better value if you do any regular trade work. For a genuine one-off — say you’re an office worker helping a mate with a weekend landscaping project — some insurers offer short-term or single-project cover. But if you do trade work more than a few times a year, an annual policy is almost certainly the right call. The premium difference between an annual policy and a one-month short-term policy is often small enough that the annual policy makes sense after two or three jobs.

Does PL cover damage caused by my subcontractors?

Usually yes — but on the condition that your subcontractors either carry their own PL insurance or you’ve disclosed them to your insurer and they’ve been accepted. If an uninsured subcontractor causes damage on your job, your PL policy may respond, but your insurer will almost certainly pursue recovery from the subcontractor afterwards. The cleanest approach is to require all subcontractors to carry their own PL and provide you with a certificate of currency before they start.

Is public liability insurance tax deductible?

Yes. PL premiums are a business expense and fully tax deductible in the year you pay them. Keep your policy documents and payment receipts for your tax records. If you prepay a policy that covers a period extending into the next financial year, the deduction may need to be apportioned — check with your accountant.

What to do next

If you don’t have PL insurance, or your policy is up for renewal, the most practical next step is to compare quotes. Premiums vary significantly between insurers for the same trade and cover level, and the market shifts year to year.
