Mate, I’ve seen it happen more times than I care to count. You’re halfway through a bathroom renovation, just pulled up the old floorboards, and you find a water leak that’s been rotting the joists for years. The homeowner is already stressed about the delay, and now you’re looking at a $5,000 fix you didn’t price into the quote. That’s when the real question hits: “Am I covered for this?” If you’re a tradie doing home renovations—whether it’s kitchens, bathrooms, extensions, or full-house reno’s—insurance isn’t just a box to tick. It’s the difference between walking away from a job with your business intact and losing everything because of one bad call. I’ve been in the game for over 20 years, and I’ve made every mistake in the book, so let me save you the headaches. Here’s what you need to know about insurance for home renovation jobs in Australia, straight up.

Why Renovation Work Is a Different Beast for Insurance

Home renovations aren’t the same as new builds or maintenance work. When you’re renovating, you’re dealing with existing structures, hidden surprises, and homeowners who are living through the chaos. That changes your risk profile big time. Insurers know that renovation jobs have higher chances of things like accidental damage to existing fixtures, water leaks from old pipes, or even injury to a homeowner who wanders into your work zone.

For example, in 2026, the average cost of a public liability claim for a renovation tradie in Australia sits between $15,000 and $50,000, depending on the severity. That’s not including legal fees. If you don’t have the right cover, you’re paying that out of your own pocket. Most states, including NSW, VIC, and QLD, require you to have public liability insurance of at least $10 million to get licensed for renovation work. In WA and SA, it’s typically $20 million for high-risk jobs. Don’t skimp here—$10 million is the bare minimum, and I’d recommend $20 million if you’re doing any structural work.

The Hidden Risks You Don’t See Coming

Renovation jobs are full of surprises. You might be tiling a splashback and accidentally crack a pipe behind the wall. Or you’re demo’ing a kitchen and a chunk of plaster hits a gas line. These aren’t rare—they’re everyday risks. Your standard public liability policy might cover damage to the homeowner’s property, but it won’t cover your tools, your van, or the cost of fixing your own mistakes. That’s where you need to look deeper.

The Core Insurance Policies Every Renovation Tradie Needs

You can’t just grab one policy and call it done. Renovation work requires a bundle of covers that work together. Here’s the shortlist of what you need, and why each one matters.

Public Liability Insurance

This is the non-negotiable. Public liability covers you if you cause injury to someone else or damage their property while on the job. For a renovation, that includes the homeowner, their neighbours, or even a delivery driver who trips over your tools. In 2026, premiums for renovation tradies range from $800 to $2,500 per year, depending on your trade, turnover, and the state you’re in. For example, a plumber in NSW doing bathroom reno’s might pay around $1,200 a year, while a builder in VIC doing full-house renovations could be closer to $2,000.

Contract Works Insurance

This one’s a lifesaver for renovation jobs. Contract works insurance covers the materials and work in progress on-site. Say you’ve ordered $10,000 worth of custom cabinetry for a kitchen reno, and a storm floods the house before you install it. Without contract works, you’re wearing that cost. For renovation jobs, this policy typically covers theft, fire, storm damage, and accidental damage during construction. Premiums usually sit between $500 and $1,500 per year, based on the value of the project.

Tools and Equipment Insurance

Your tools are your livelihood. If your ute gets broken into on site and they swipe your $5,000 drill set, you’re not working until you replace them. Tools insurance covers theft, loss, or damage to your equipment, whether it’s in your van or on the job. For a renovation tradie, this can range from $300 to $800 per year. Don’t assume your home insurance covers tools on site—it usually doesn’t.

Professional Indemnity Insurance

This one’s less common for tradies, but if you’re offering design advice—like suggesting a new layout for a kitchen or bathroom—you might need it. Professional indemnity covers you if a client claims your advice caused them financial loss. For example, you recommend a waterproofing system that fails, and the homeowner has to rip out the whole bathroom. That claim could hit $20,000 or more. Premiums for renovation tradies start around $400 per year for basic cover.

State-by-State Requirements You Can’t Ignore

Insurance rules vary across Australia, and if you work in multiple states, you need to know what applies where. Here’s a quick rundown based on 2026 regulations.

  • NSW: You need public liability of at least $10 million for any renovation work over $5,000. Also, if you’re doing structural work, you must have home warranty insurance for projects over $20,000.
  • VIC: Public liability of $10 million is standard, but for domestic building work over $16,000, you need domestic building insurance (DBI) to cover the homeowner if you don’t finish the job.
  • QLD: You need public liability of $10 million for any building work, and for renovations over $3,300, you must hold a QBCC licence, which requires proof of insurance.
  • WA: Public liability of $20 million is typical for renovation work, and you need home indemnity insurance for projects over $20,000.
  • SA: Public liability of $10 million is required, and for renovations over $12,000, you need a building work contract with insurance details.
  • TAS, ACT, NT: These territories generally require public liability of $10 million, with specific rules for high-value projects. Check with your local licensing body.

If you’re working across borders, platforms like BizCover let you compare quotes from multiple insurers to find cover that meets each state’s rules. Just make sure your policy is valid in all states you operate in.

Common Claims Tradies Face on Renovation Jobs

I’ve seen mates make these mistakes, and they cost them thousands. Here are the most common claims and how to avoid them.

Accidental Damage to Existing Structures

You’re cutting into a wall to run new plumbing, and you hit a live electrical wire. That’s a $2,000 to $5,000 fix, plus potential injury. Always check for hidden services before you start—use a cable detector. And make sure your public liability covers accidental damage, not just negligence.

Theft of Materials or Tools

Renovation sites are prime targets for thieves, especially when you leave materials overnight. In 2026, tool theft costs tradies an average of $3,500 per incident. Keep tools locked in a secure van or on site, and get tools insurance that covers theft from a vehicle.

Injury to a Homeowner or Bystander

A homeowner walks into your work area and trips over a loose board. That’s a public liability claim, and it can run into tens of thousands for medical costs and legal fees. Always cordon off work zones, and don’t let clients wander around.

Water Damage from Plumbing Work

You’re installing a new shower, and a joint fails overnight. Water leaks into the ceiling below, causing $10,000 in damage. Your public liability should cover this, but check if there’s an exclusion for gradual damage. Some policies only cover sudden, accidental leaks.

How to Choose the Right Insurance for Your Renovation Business

You don’t need to be an insurance expert, but you do need to ask the right questions. Here’s a checklist I use with my own business.

Assess Your Risk Profile

What kind of renovation work do you do? A painter doing cosmetic touch-ups has different risks than a builder knocking down walls. List your typical jobs, the value of materials you handle, and whether you work alone or with subcontractors. This helps you decide what cover you need.

Compare Policies, Not Just Prices

Cheapest isn’t always best. A $800 policy might exclude cover for theft from a vehicle or limit you to $5 million liability. For renovation work, you want at least $10 million public liability, plus contract works and tools cover. Use comparison platforms to see what’s out there, but read the fine print.

Check for Exclusions

Every policy has exclusions. Common ones for renovation tradies include:

  • Damage from faulty workmanship (your own mistakes)
  • Wear and tear on existing structures
  • Theft from unattended vehicles without a locked storage area
  • Claims related to asbestos removal (you need separate cover for that)

If you’re doing any demolition or structural work, ask your insurer about these exclusions.

Consider Your Turnover

Your premium is partly based on your annual turnover. A tradie doing $200,000 in renovation jobs will pay less than one doing $500,000. Be honest about your turnover—underestimating it could void your claim. In 2026, premiums for renovation tradies with turnover under $200,000 range from $1,200 to $2,500 for a comprehensive package.

FAQ: Insurance for Home Renovation Jobs

Do I need insurance if I’m just doing a small kitchen reno?

Yes, absolutely. Even a small renovation carries risk. If you damage a pipe or injure someone, you’re liable. Most states require public liability insurance for any paid renovation work, no matter the size.

What’s the difference between public liability and contract works insurance?

Public liability covers injury or damage to others and their property. Contract works covers the materials and work in progress on your site. You need both for a renovation job—one protects you from lawsuits, the other from financial loss on materials.

Can I use my home insurance for my tools on site?

Generally, no. Home insurance policies often exclude tools used for business purposes. You need separate tools and equipment insurance to cover theft or damage on a job site.

How much does insurance cost for a renovation tradie in 2026?

For a full package—public liability, contract works, and tools cover—you’re looking at $1,500 to $3,500 per year, depending on your trade, turnover, and state. A plumber in NSW doing $300,000 turnover might pay around $2,000.

What happens if I work in multiple states?

You need a policy that covers you in all states you operate. Some insurers offer national cover, but check the fine print. Platforms like BizCover can help you compare policies that work across borders.

Do I need insurance for subcontractors I hire?

If you hire subcontractors, you need to check their insurance. They should have their own public liability and workers’ comp. If they don’t, you could be liable for their mistakes. Always get a copy of their certificate of currency before they start.

Is asbestos removal covered under standard renovation insurance?

No, standard policies usually exclude asbestos removal. If you’re working on older homes—common in renovations—you need separate asbestos cover or a specialist policy. This can add $500 to $1,000 to your premium.

Can I claim insurance if I make a mistake in my work?

It depends. Most policies exclude faulty workmanship—your own errors. But they may cover the resulting damage. For example, if you install a pipe wrong and it leaks, the cost to fix the pipe is on you, but the water damage to the homeowner’s property might be covered. Always clarify this with your insurer.
