You Supply the Materials? Then You Need This Cover

Let me tell you about a mate of mine, let’s call him Steve. Steve’s a solid chippy, been running his own show for about three years. He takes on a small deck job for a young family. Supplies the timber, the screws, the stain – the whole lot. Six months later, he gets a call. The stain he used has started peeling in patches. The family’s worried about splinters for their kids. They’re not just asking for a fix; they’re talking about the cost of ripping up the whole deck and replacing it. Steve’s public liability covers him for accidents on site, but it doesn’t cover the cost of replacing the faulty product he supplied. That’s a $15,000 bill coming straight out of his pocket.

If you’re a tradie who buys and supplies materials as part of your job – whether it’s plumbing fittings, electrical cables, roofing sheets, or even paint – you’ve got a double exposure. You’re liable for your workmanship, sure. But you’re also liable for the products you supply. That’s where Product Liability Insurance comes in. It’s not just for manufacturers. It’s for any tradie who puts a product into the hands of a customer. And in 2026, with material costs through the roof and customers more litigious than ever, skipping this cover is a gamble you don’t want to take.

This guide will walk you through exactly what product liability insurance covers, why you need it, what it costs, and how to make sure you’re not left holding the bag when something goes wrong with a product you supplied.

What Is Product Liability Insurance for Tradies?

Product liability insurance is a specific type of cover that protects you if a product you supply causes injury, loss, or damage to a customer or their property. Think of it as the cousin to your public liability insurance. Public liability covers you for accidents that happen while you’re working – like if you drop a hammer on a client’s car. Product liability covers you for problems caused by the product itself – like a faulty pipe fitting that bursts and floods a kitchen.

It’s easy to think this only applies if you manufacture your own goods. But in Australia, the law sees things differently. If you buy a product and then supply it to a customer as part of your service, you’re considered a “supplier” in the eyes of the law. That means you can be held responsible if that product is defective.

What It Covers

  • Legal defence costs – If a customer sues you, the legal bills can pile up fast. Product liability covers your legal fees, even if the claim is groundless.
  • Compensation payouts – If you’re found liable for damage or injury caused by the product, the policy pays the compensation.
  • Cost of recall – If you supply a batch of faulty materials and need to recall them from multiple job sites, some policies cover the cost of that process.
  • Damage to third-party property – If a faulty product damages your customer’s home (like a burst hot water system), you’re covered.

What It Doesn’t Cover

  • Your own faulty workmanship – That’s usually covered under a separate policy or a specific endorsement.
  • The cost of replacing the product itself – Most policies won’t pay for the direct cost of the faulty goods. They cover the consequences of the fault.
  • Intentional damage – If you knowingly supply a dodgy product, you’re on your own.

Why Tradies Who Supply Materials Need This Cover

Here’s the thing: even if you’re the best tradie in your state, you can’t control every single thing that comes out of a factory. Materials fail. Batteries explode. Fittings crack. And when they do, the customer doesn’t usually go after the manufacturer – they go after you. You’re the one they hired. You’re the one on site. You’re the one with the invoice.

Real-Life Scenarios

  • Plumber supplies a cheap tap from a hardware store. The ceramic disc inside shatters after three months, causing water damage to a new kitchen. The tap manufacturer blames improper installation. You’re stuck in the middle.
  • Electrician supplies a batch of LED downlights. One overheats and starts a small fire. The fire damage is $30,000. Your public liability might cover the fire, but if the downlight is deemed a defective product, you could be on the hook for the product liability claim separately.
  • Landscaper supplies a retaining wall block that crumbles after a wet season. The wall collapses and damages the neighbour’s fence. The block supplier says it was “not suitable for your soil type.” Guess who the customer sues?

Australian Consumer Law (ACL) is strict. It gives customers automatic rights – called consumer guarantees – that the products you supply must be of acceptable quality, fit for purpose, and match their description. If they don’t, the customer can claim a remedy from you, the supplier, even if you didn’t manufacture the product. In 2026, the ACCC is actively targeting tradies who supply faulty goods, especially in the building and construction sector.

State regulations also play a role. In NSW, the Home Building Act requires contractors to provide warranties on work and materials. In Victoria, the Domestic Building Contracts Act imposes strict liability on builders for materials supplied. Queensland has similar provisions under the Queensland Building and Construction Commission Act. In Western Australia, the Home Building Contracts Act 1991 requires clear disclosure of materials supplied. South Australia, Tasmania, ACT, and NT all have their own versions of consumer protection laws that hold suppliers accountable.

The bottom line: if you supply it, you’re liable for it. And in 2026, with court costs averaging $50,000–$100,000 for a defended claim, even a small dispute can bankrupt a small business.

How Much Does Product Liability Insurance Cost in 2026?

Pricing for product liability insurance for tradies in Australia varies based on a few key factors. You won’t find a one-size-fits-all price, but here’s a realistic breakdown based on 2026 market data.

Typical Premium Ranges

  • Low-risk trades (painters, plasterers, landscapers supplying basic materials): $800–$1,500 per year
  • Medium-risk trades (plumbers, electricians, roofers supplying fittings or components): $1,200–$2,500 per year
  • High-risk trades (gas fitters, refrigeration mechanics, anyone supplying electrical or gas appliances): $2,000–$4,000 per year

What Drives the Price

  • Your turnover – Higher turnover means you supply more products, which means more exposure. Insurers will ask for your annual revenue.
  • Type of materials – Supplying structural steel is different from supplying paint. High-risk materials drive up premiums.
  • Claims history – One claim can double your premium. A clean record keeps costs down.
  • Cover limits – Most tradies opt for $10 million or $20 million in cover. Higher limits cost more.
  • State – Premiums can vary slightly by state due to different regulatory environments and legal costs. NSW and Victoria tend to be a bit higher than SA or TAS due to higher legal costs.

How to Get the Best Price

  • Bundle with public liability – Many insurers offer a package that includes both. It’s usually cheaper than buying separately.
  • Compare quotes – Don’t just go with your current insurer. Platforms like BizCover let you compare quotes from multiple insurers in minutes. It’s worth doing once a year.
  • Increase your excess – A higher excess (say $1,000 instead of $500) can lower your premium significantly.
  • Review your turnover – If your turnover drops, update your insurer. Overestimating it means you’re paying for cover you don’t need.

What to Look for in a Product Liability Policy

Not all product liability policies are created equal. Some have exclusions that can catch you out. Here’s what to check before you sign.

Key Cover Features

  • Defence costs included – Make sure legal defence costs are covered in addition to the limit of liability, not inside it. This is standard but worth confirming.
  • Retroactive cover – If you’ve been supplying materials for years, check if the policy covers claims arising from work done before the policy started. Some policies exclude this.
  • Cross-liability – If you’re in a partnership or company, this ensures each partner or director is covered separately.
  • Territorial limits – Does it cover you if a job takes you across the border into another state? Most policies do, but check.
  • Product recall cover – Some policies offer this as an optional extra. If you supply high volumes of the same product, it’s worth considering.

Common Exclusions to Watch For

  • Faulty workmanship – Most product liability policies exclude your own faulty workmanship. You need a separate policy for that.
  • Wear and tear – Products that fail due to normal wear and tear aren’t covered.
  • Known defects – If you knew a product was faulty and supplied it anyway, you’re not covered.
  • Asbestos or hazardous materials – Standard policies exclude these. You’d need a specialist policy.

Do You Need $10 Million or $20 Million Cover?

Most tradies in Australia carry $10 million in public and product liability cover. That’s usually enough for a small to medium business. But if you work on high-value projects (like custom homes or commercial fit-outs), or if you supply expensive materials (like custom joinery or imported appliances), $20 million might be wiser. The premium difference is often only a few hundred dollars a year.

How Product Liability Insurance Works with Other Covers

You’ve probably already got public liability insurance. Maybe you’ve got tools insurance too. Here’s how product liability fits into the bigger picture.

Product Liability vs. Public Liability

  • Public liability covers injury or damage caused by your actions on site (e.g., you trip over a lead and knock over a client’s vase).
  • Product liability covers injury or damage caused by the product you supplied (e.g., a faulty valve causes a flood).

Many tradies think public liability covers everything. It doesn’t. If a product fails, the claim often falls under product liability, not public liability. If you don’t have product liability cover, you’re paying out of pocket.

Product Liability vs. Professional Indemnity

  • Professional indemnity covers you for advice or design errors (e.g., you specify the wrong pipe size for a drainage system).
  • Product liability covers physical products, not advice.

If you’re a tradie who also does design or consultancy work (like an engineer or a building designer), you might need both.

Do You Need It If You Have Public Liability?

Yes. Most public liability policies specifically exclude claims arising from products you supply. Check your policy wording. If it says “products liability” is excluded, you have a gap. Some insurers offer a combined policy that includes both. If yours doesn’t, you need a separate product liability policy.

State-by-State Considerations in 2026

While product liability insurance is a national issue, each state has its own quirks that affect how claims are handled and what you’re required to carry.

New South Wales

  • Home Building Act requires builders and tradies to provide warranties on materials for up to 6 years for structural defects.
  • NSW Fair Trading actively investigates complaints about faulty materials.
  • Premiums are slightly higher due to higher legal costs in Sydney.

Victoria

  • Domestic Building Contracts Act imposes strict liability on builders for materials supplied.
  • Victorian Building Authority can issue fines for supplying non-compliant products.
  • Product liability claims are common in the plumbing and electrical sectors.

Queensland

  • QBCC requires contractors to hold insurance for residential work over $3,300.
  • Product liability is often bundled into the QBCC insurance scheme, but check if it covers materials you supply.
  • Higher risk for tradies supplying imported materials due to compliance issues.

Western Australia

  • Home Building Contracts Act requires clear disclosure of materials supplied.
  • WA has a higher rate of claims related to imported building products.
  • Premiums are generally lower than the eastern states.

South Australia, Tasmania, ACT, NT

  • All follow the Australian Consumer Law with local variations.
  • Smaller markets mean fewer insurers, so premiums can be slightly higher for niche trades.
  • ACT has specific requirements under the Building Act 2004 for materials used in residential construction.

FAQ: Product Liability Insurance for Tradies

Do I need product liability insurance if I only supply materials occasionally?

Yes. Even one job where you supply a faulty product can result in a claim. If you supply materials at all – even once a year – you need cover. The cost is low compared to the risk.

Does my public liability insurance already cover product claims?

Not usually. Most standard public liability policies exclude claims arising from products you supply. You need a separate product liability policy or a combined policy that includes it. Check your policy wording carefully.

What’s the difference between product liability and professional indemnity?

Product liability covers physical products that cause damage or injury. Professional indemnity covers advice, designs, or services that cause financial loss. If you supply materials and give advice about them (like a plumber recommending a specific brand of hot water system), you might need both.

Can I get product liability insurance if I have a claims history?

Yes, but it will cost more. Some insurers specialise in high-risk trades or businesses with prior claims. You’ll need to disclose the claims and explain what you’ve done to prevent them recurring. Expect a higher excess and a premium loading of 20–50%.

How much cover do I need for a small trade business?

For most sole traders and small businesses, $10 million is standard and sufficient. If you work on high-value projects or supply expensive materials, consider $20 million. The extra cost is usually minimal.

Does product liability cover the cost of replacing the faulty product?

No. Product liability covers the consequences of the fault – like water damage, fire damage, or injury – but not the cost of replacing the faulty product itself. That’s considered a business cost. Some policies offer optional “product recall” cover that can help with replacement costs.

Do I need product liability insurance if I only use materials I buy from a hardware store?

Yes. You are still the supplier. If the product fails, the customer will come to you first. You can try to recover your costs from the manufacturer, but you’ll need your own insurance to cover the initial claim and legal defence.

How do I compare product liability policies?

Look at the cover limits, exclusions, excess amounts, and whether defence costs are covered inside or outside the limit. Get quotes from at least three insurers. Platforms like BizCover let you compare policies side by side. Don’t just go for the cheapest – read the fine print.

Final Word from an Old Hand

Look, I’ve been in the game long enough to see blokes lose everything over a single faulty fitting. It’s not fair, but that’s the way the law works. You supply it, you own it. Product liability insurance is cheap peace of mind. For a few hundred bucks a year, you can sleep easy knowing that if a batch of materials turns out to be a lemon, you’re not going to lose your ute, your tools, or your house.

Don’t wait until you get a letter from a lawyer. Check your current policy today. If it doesn’t mention product liability, you’ve got a gap. Fill it. Your future self will thank you.
