If you're a licensed plumber working in Brisbane, whether you're a sole trader doing residential maintenance, running a team on commercial fit-outs, or specialising in gas or drainage. Insurance isn't something you want to figure out after something goes wrong.
Plumbing sits in one of the higher-risk categories for tradies in Queensland. You're working with water, gas, and drainage systems in people's homes and businesses. When things go wrong, they can go wrong fast and the damage can be expensive, widespread, and immediate.
Here's exactly what insurance a Brisbane plumber needs, explained in plain language.
1. Public Liability Insurance
If there's one policy every plumber in Brisbane must have, it's this one.
Public liability insurance covers you if your work causes injury to a third party or damage to someone else's property. For a plumber, the scenarios are very real and very costly:
A burst pipe following your work floods a client's home or the unit below
A gas fitting error causes a leak that damages a property or injures an occupant
You accidentally damage a neighbouring property while accessing pipes under a home
A client or their family member trips over your equipment on site
Sewage backup from a drainage job damages a client's flooring, walls, or contents
Water damage claims in particular can escalate quickly. A pipe failure in a multi-storey apartment building or a commercial premises can cause damage across multiple tenancies simultaneously and the bill can run into the hundreds of thousands before you've even thought about legal costs.
How much public liability do you need? For residential plumbing work, a minimum of $5 million is the starting point but most Brisbane plumbers working on commercial jobs, strata buildings, or under head contractors will be required to hold $10 million or $20 million as a contractual condition before stepping on site.
If you do any gas work, some principal contractors and body corporates will specifically require $20 million given the severity of potential gas-related incidents. Always check your contracts before starting a new job.
2. Tools and Equipment Insurance
A Brisbane plumber's toolkit is a significant investment. Between pipe cutters, drain cameras, hydro-jet machines, pressure testing equipment, gas analysers, and power tools, a well-equipped plumber can easily have $15,000 to $40,000 worth of tools and equipment.
Tools insurance covers your gear against theft, loss, and accidental damage, whether it's in your van, on site, or at your workshop.
The most important things to check in your policy:
Overnight vehicle theft - Break-ins to tradie vans are one of the most common insurance claims in Queensland. Many budget policies specifically exclude tools stolen from an unattended vehicle after hours. If your van is parked on the street overnight with tools inside, make sure your policy explicitly covers this.
Drain cameras and specialist equipment — these are high-value, easily damaged items. Check there's no per-item cap that leaves you underinsured on your most expensive gear.
Hired or borrowed equipment — if you regularly hire specialist equipment like pipe relining machinery or hydro-jetting units, check whether your policy covers hired-in equipment or whether you need a separate hired plant extension.
New for old replacement — always preferable to depreciated value. If a three-year-old drain camera worth $8,000 is stolen, you want a new one, not $4,000 based on depreciated value.
3. Personal Accident Insurance
This is the one most plumbers don't think about until they need it and by then it's too late.
Plumbing is physically demanding work. You're working in confined spaces, under houses, in roof cavities, on ladders, and in all weather conditions. Back injuries, knee injuries, falls, and repetitive strain injuries are among the most common claims for plumbers in Queensland.
If you're a sole trader and you can't work due to injury or illness, there is no sick pay, no workers compensation (that only covers your employees, not you), and no one else to keep the income flowing.
Personal accident insurance pays a weekly benefit while you recover from an injury sustained at work or outside work. For a sole trader plumber with a mortgage, family, and business overheads to cover, this cover is not optional. It's the policy that keeps everything else standing when you can't.
4. Workers Compensation
If you have employees apprentices, labourers, or other plumbers on your payroll then workers compensation is compulsory in Queensland. No exceptions.
Workers' compensation covers your employees if they're injured at work, paying for medical treatment, rehabilitation, and lost wages. In Queensland, you must hold a WorkCover Queensland policy before your first employee starts work and not after.
Apprentices are employees from day one. Make sure they're on your WorkCover policy before they set foot on a job site.
A note on subcontractors: If you engage other plumbers or labourers as subcontractors rather than employees, they generally fall outside your workers compensation policy. Before any subcontractor starts work for you, request a current certificate of currency for their own personal accident or workers compensation cover. Making this a standard part of your onboarding process protects you from an ugly situation if they're injured on your watch.
5. Professional Indemnity Insurance
Professional indemnity (PI) is becoming increasingly relevant for plumbers particularly those who provide design advice, hydraulic consulting, compliance certifications, or building approval documentation alongside their trade work.
If a client suffers a financial loss because of your professional advice or recommendations, not just your physical work then PI insurance is what responds. For example:
You advise on a drainage design that later proves non-compliant
You certify plumbing work that is subsequently found to breach the Plumbing and Drainage Act
You recommend a hot water system that proves inadequate for a commercial application
If your work involves any element of specification, design, or professional recommendation rather than pure installation, professional indemnity is worth having a conversation about with your broker.
6. Commercial Motor Vehicle Insurance
Your ute or van is your mobile workshop and without it you can't work. Make sure it's insured correctly for business use.
A standard personal motor vehicle policy often excludes or limits cover when the vehicle is used commercially whether that be carrying tools, travelling between job sites, or operating as a work vehicle. You need a commercial motor vehicle policy that accurately reflects how the vehicle is used.
For sign-written vehicles: If your van has your business name, logo, and phone number on it, discuss agreed value cover with your broker. The replacement cost of a branded work vehicle is higher than its book value, and getting that figure locked in upfront avoids a dispute if you need to claim.
For trailers: If you tow a trailer carrying equipment or a water jetter, make sure the trailer is separately insured and that your policy covers third-party liability while loading and unloading on public roads.
7. Contract Works Insurance
If you're engaged on construction or renovation projects and not just one-off maintenance jobs. Then contract works insurance protects the physical works being carried out against damage before completion.
A storm overnight, a flood, a fire, or accidental damage to work already completed can set a project back significantly. Contract works insurance covers the cost of reinstating that work so you're not absorbing the loss out of your own pocket.
Whether you need your own policy depends on how you're engaged:
If you're a subcontractor under a head contractor, check whether the principal's policy covers your scope of works
If you're engaged directly by the client with responsibility for the full project, you likely need your own cover
Always clarify this before signing a contract. Don't assume you're covered under someone else's policy without seeing the certificate of currency.
What Does Plumber Insurance Cost in Brisbane?
Costs vary depending on your annual turnover, number of employees, type of work, claims history, and whether you do gas work (which some insurers treat as a higher-risk category). As a rough guide for a Brisbane sole trader plumber:
Public Liability ($10M): $1,200 – $2,500 per year
Tools Insurance: $500 – $1,200 per year depending on the value of your kit
Personal Accident: $1,000 – $2,500 per year depending on your income level
Commercial Motor Vehicle: $1,500 – $3,000 per year
A small plumbing business with two or three employees will pay more across each category, but packaging these covers together through a broker almost always reduces the overall cost compared to buying each policy separately.
The One Thing Brisbane Plumbers Often Get Wrong
The most common mistake we see is plumbers assuming their public liability policy covers all the work they do without reading the exclusions.
Some policies specifically exclude:
Gas work — treated as a separate, higher-risk category by some insurers
Damage caused by tree root removal — excluded by some policies as a maintenance issue
Gradual damage or seepage — water damage that develops slowly over time rather than from a sudden event
Work on high-rise or multi-storey buildings — some policies have height or building type exclusions
If your policy excludes the work you actually do day-to-day, it's not worth the paper it's written on. Reading the Product Disclosure Statement carefully or better yet, working with a broker who understands the plumbing trade, is what protects you when you actually need to make a claim.
The Bottom Line
A well-covered Brisbane plumber should have at minimum:
Public Liability — $10M minimum, $20M for gas work or commercial sites
Tools and Equipment — new for old, checking the overnight vehicle exclusion
Personal Accident / Income Protection — essential for sole traders
Workers Compensation — mandatory if you have employees
Commercial Motor Vehicle — business use confirmed on the policy
Getting these five right is the foundation. Contract works, professional indemnity, and hired plant cover layer on top depending on the type of work you do.
