The Insurance Shift: What Changes When You Go Out on Your Own
Making the jump from employed plumber to subcontractor or sole trader is a big decision. The money can be better, the flexibility is appealing, and you control your own work. But one thing changes overnight that catches a lot of plumbers off guard: you become responsible for your own insurance.
As an employee plumber, your boss handles workers comp, public liability sits with the company, and your tools were probably provided or at least partly covered. You might have had income protection through your super fund without giving it much thought. When you step out as a subcontractor, every one of those insurance protections either disappears or becomes your personal responsibility.
The insurance shift isn’t just about buying a few policies. It’s about understanding that the safety net that was quietly protecting you as an employee is now something you have to build and maintain yourself.
Here’s exactly what changes and what you need to do about it.
What Your Employer Covered (That You Now Need to Handle)
When you were an employee, your boss or company carried:
Public liability insurance — if you accidentally flooded a customer’s house or damaged property on site, the company’s PL covered the claim. You were covered as an employee acting within the scope of your employment. As a subcontractor, you need your own PL policy. The head contractor’s policy might not extend to subcontractors, and even if it does, relying on someone else’s insurance to protect you is a risky strategy.
Workers compensation — your employer paid this and it covered you for workplace injuries. As a sole trader subcontractor, you’re not an employee, and in most states, workers comp doesn’t apply to you unless you opt in. You need income protection or personal accident insurance to fill this gap.
Tools and equipment — if the company supplied your tools, you had no tools insurance to worry about. As a subcontractor bringing your own gear, you’re carrying thousands of dollars of equipment in your van across multiple sites. Tools theft from vehicles and job sites is a major issue for plumbers, and you need your own cover.
Professional indemnity — most employee plumbers never think about PI insurance because the company held it. As a subcontractor doing design, consulting, or compliance work, you might need your own PI policy, particularly if your work involves signing off on compliance certificates or providing advice that clients rely on.
Vehicle insurance — you might have had access to a company vehicle. Now your personal vehicle is your work vehicle, and you need to check that your insurance covers business use. Standard personal car insurance often excludes business use, and tools in the vehicle may not be covered under a standard policy.
The ATO Distinction: Contractor vs Employee
Before getting into the insurance specifics, you need to understand the legal distinction between a contractor and an employee. The ATO and Fair Work use a multi-factor test, and the label on your contract doesn’t determine your status. Getting this wrong has both tax and insurance consequences.
The ATO looks at factors including:
- Control: Who decides how, when, and where the work is done? If the head contractor tells you where to be at 7am each day and how to do every job, you look like an employee.
- Risk: Who bears the commercial risk? A genuine contractor quotes for jobs and carries the risk of cost overruns.
- Equipment: Do you provide your own substantial tools and equipment? A plumber who turns up with their own van, tools, and testing gear is more likely to be a contractor than someone who uses the company’s gear.
- Ability to delegate: Can you send someone else to do the work? Contractors can subcontract; employees cannot.
- Independence: Do you work for multiple clients, or just one? A plumber who works exclusively for one builder for years looks increasingly like an employee.
The legal distinction matters for insurance because it determines who’s responsible for what. If you’re genuinely a contractor, you carry the insurance burden. If a court later determines you were actually an employee, your “employer” was responsible for workers comp — and you might have been paying for PL and income protection unnecessarily. But the reverse is more dangerous: thinking you’re a contractor and finding out you’re not.
What Head Contractors Typically Require From You
When you subcontract to a building company, plumbing firm, or commercial contractor, they’ll almost always ask for proof of insurance before you start work. This is standard practice and you should expect it. Specific requirements typically include:
Certificate of currency for public liability: This is non-negotiable. Most head contractors require minimum $10 million or $20 million in PL cover. Some large commercial projects or government contracts require $20 million as the floor. You’ll need to provide a current certificate before stepping on site, and you may be asked to add the head contractor as an interested party on the policy.
Workers compensation (sometimes): Even though you’re a sole trader, some head contractors and project sites demand that all workers on site have workers comp coverage. This can mean you need to opt into your state’s workers comp scheme or take out a personal accident policy that satisfies the site requirements. Check exactly what the site induction paperwork requires.
Professional indemnity insurance (less common for general plumbing): If your subcontracting work includes any design, compliance certification, or advisory component, you may be asked to hold PI insurance. This is more common for plumbing work on commercial and industrial projects than for domestic work.
Income protection or accident insurance (rarely required but sometimes asked): Some larger contractors want to see that you won’t be left without income if you’re injured on their site, as it affects project continuity.
Keep your certificates of currency handy — ideally a digital copy on your phone and hard copies in the van. You’ll be asked for them constantly.
Tools Cover for Multi-Site Subcontractors
As a subcontractor moving between different job sites, your tools are exposed to more risk than an employee plumber who works from a single depot. You’re parking on streets, working in partially constructed buildings, and leaving gear in the van between jobs.
Tools insurance for plumbers typically covers theft from a locked vehicle (with signs of forced entry), theft from a secure job site, and accidental damage. The key things to watch for are the per-item sub-limit (some policies cap individual tool claims at $500-2,000, which won’t cover a pipe camera or test equipment worth $8,000), overnight theft exclusions (some policies don’t cover tools left in a vehicle overnight, even if locked), unspecified items limits (tools worth under a certain amount might not need to be individually listed, but anything above that threshold needs to be specified), and proof of ownership requirements (keep receipts, serial numbers, and photos of your tools — claims get denied over insufficient proof).
If your tools are your livelihood and you work across multiple sites, tools cover isn’t optional. A $15,000 loadout of plumbing tools can disappear from a locked van in under two minutes. Check your policy’s per-item limits against what your tools actually cost to replace — a $500 per-item cap is useless if your drain camera costs $6,000.
The Income Protection Gap
When you leave employment, you lose several layers of income protection you might not have realised you had:
Your employer’s sick leave and annual leave provided a short-term buffer. As a subcontractor, there’s no sick pay — if you don’t work, you don’t earn.
Your employer’s workers comp covered workplace injuries. As a sole trader subcontractor, unless you opt in to workers comp (where available), a workplace injury means zero income until you recover, minus whatever you’ve arranged yourself.
Your super fund might have provided default income protection, TPD, and life insurance. Check whether this continues after you leave employment — some policies lapse when contributions stop.
The income protection conversation is often the one new subcontractors put off because it feels like an expense they can avoid. Then a back injury or a fall from a ladder happens, and three months without income burns through every dollar they saved from going out on their own.
Take out income protection before you start your first subcontracting job. If you wait and something happens, you can’t backdate cover.
Insurance Through Super: What You Might Already Have
Most industry super funds include default insurance — usually life cover, TPD, and sometimes income protection. These default policies are group policies with simplified underwriting, which means they’re easy to get but often have limitations.
Check your super statement. You might already be paying for income protection without realising it. Common features of super-based income protection include indemnity value only (not agreed value), limited benefit periods (often 2 or 5 years), default cover amounts that may be far below what you need, and definitions of disability that may be “any occupation” rather than “own occupation”.
The advantage is obvious: it’s paid from super so it doesn’t hit your cash flow. The disadvantage is equally obvious: it might not pay you enough, for long enough, or at all if you can theoretically do any job.
Many plumbers use super-based cover as a foundation and top up with an external retail policy for better definitions and higher benefit amounts. Talk to a financial adviser about your options if you want to go down this path.
Sham Contracting: The Insurance Time Bomb
Sham contracting is when an employer treats a worker as a contractor to avoid paying entitlements and workers comp — and it’s illegal. For you as a plumber, the insurance implications of being in a sham contracting arrangement are serious.
If you’re told you’re a subcontractor but the reality is that you work like an employee (set hours, one boss, their tools, their van, their direction), and you’re injured on the job, the following can unfold: your income protection might not pay if you haven’t taken it out, your personal accident insurance might have exclusions that apply, your “employer” has no workers comp for you because they called you a contractor, and you’re left without coverage while the legal argument plays out over who should have insured you.
The Fair Work Ombudsman takes sham contracting seriously, and penalties can be severe for the employer. But penalties don’t pay your medical bills while you’re recovering from an injury.
If something about your contractor arrangement doesn’t feel right — you’re using their gear, working their hours, and have no real independence — get advice. An accountant or employment lawyer can review your arrangement and tell you where you stand. The cost of the advice is trivial compared to the cost of being uninsured when something goes wrong.
Building Insurance Into Your Day Rate
If you’re moving from employment to subcontracting, one of the most common mistakes is not factoring insurance costs into your rates.
When you were an employee on $40/hour, your employer was paying roughly $45-55/hour once you account for super, workers comp, payroll tax, leave entitlements, and other on-costs. As a subcontractor, your rate needs to cover all of that plus your insurance, tools, vehicle, and the fact that you don’t get paid for days you don’t work.
Here’s a rough way to think about it:
Start with your target annual income (say $100,000). Add super ($11,500 at current rates). Add insurance costs — PL, tools, income protection, PI if needed (roughly $5,000-8,000/year for a one-person operation). Add vehicle costs including commercial-use insurance. Add tool replacement and maintenance. Add accounting and admin. Add a buffer for unpaid days (sick days, public holidays, gaps between jobs). Then divide by the number of days you realistically expect to work (most subcontractors aim for 200-220 chargeable days per year after holidays, sick days, admin, and quoting).
The result is almost always higher than what you think it should be. If you end up at $550/day and competing subcontractors are quoting $450/day, they’re either more efficient than you, working more days, or — more likely — not properly accounting for their full costs and insurance.
Don’t compete on price with people who aren’t properly insured. It’s a race to the bottom that you’ll lose, either financially or when a claim hits and you discover the other plumber wasn’t covered.
PL Insurance for Subcontractors: Same Product, Different Context
The public liability policy you need as a subcontractor is essentially the same product that a plumbing company buys — it covers third-party property damage and personal injury caused by your work. The difference is that you hold the policy in your name, and the sum insured is based on your individual risk, not a company’s total operations.
Most subcontractor plumbers need $10 million or $20 million in PL cover — same as what a plumbing company carries. The premium for a sole trader plumbing subcontractor might range from $600 to $1,500 per year depending on your turnover, the type of work you do, your claims history, and the specific insurer.
Make sure your PL policy covers:
- Work done on multiple sites (not restricted to a single premises)
- Work at heights and in confined spaces (some policies exclude or limit these)
- Hot work (soldering, brazing — some policies exclude or require a separate endorsement)
- Asbestos-related claims (many PL policies now exclude asbestos, which is a problem for plumbers working on older buildings)
- Damage caused by your tools or equipment (dropping a pipe wrench through a glass splashback, for example)
Let the insurer know that you’re a subcontractor working on different sites for different builders — this should be standard for trade PL, but it’s worth confirming.
Multi-Site Risk: Why Subcontractors Need Stronger Tools Cover
An employee plumber typically works from a single base. Tools stay in the company workshop or a secure depot overnight. As a subcontractor, you’re bouncing between three or four sites a week, parking on the street, in apartment building basements, or on construction sites with varying levels of security.
The theft risk is materially higher. Industry data from insurers shows that tools in transit claims are one of the most common claim types for trade subcontractors. Plumbers are particularly exposed because modern plumbing tools — thermal cameras, pipe locators, drain inspection cameras, press fitting tools — are high-value, easily portable, and readily resellable.
Your tools insurance needs to account for this reality. Key protections to look for include coverage while tools are temporarily unattended on a secure job site (locked room, locked toolbox, not just sitting in an open frame), coverage in a locked vehicle with forced entry (even during the day between jobs), realistic per-item sub-limits that match the replacement cost of your most expensive tools, and new-for-old replacement rather than depreciated value.

FAQ
Do I need my own PL insurance if the head contractor has PL?
Yes. The head contractor’s PL covers their liability, not yours. If you cause damage — say you drill through a water pipe and flood a completed kitchen — the head contractor’s insurer might pay the homeowner and then pursue you for recovery. Or the head contractor’s PL might not extend to subcontractor work at all. Your own PL policy protects you directly and gives you control over claims.
I’m an employee now but doing weekend cash jobs. What insurance do I need?
Your employer’s PL and workers comp don’t cover your weekend work. If you damage a client’s property or get injured doing a cash job, you’re uninsured. At minimum, you need your own PL policy for the weekend work. Income protection or personal accident insurance is also wise — if you injure yourself on the weekend job and can’t work your regular job on Monday, your employer’s workers comp won’t cover it because the injury didn’t occur in the course of your employment.
Can I use my personal car insurance for work as a subcontractor?
Only if it explicitly covers business use. Standard personal car insurance typically excludes business use, and if you’re carrying tools and traveling between job sites, that’s business use. Tell your insurer what you’re doing and get the right cover. Also check whether your car insurance covers tools inside the vehicle — it usually doesn’t, and you’ll need a separate tools policy.
What’s the difference between a subcontractor and a labour-hire worker for insurance purposes?
A labour-hire worker is employed by the labour-hire company, which is responsible for workers comp, super, and PAYG. The host employer (the plumbing company where you work) typically has a contract with the labour-hire firm that includes insurance indemnities. A genuine subcontractor operates their own business and carries their own insurance. The distinction matters: if you’re being treated as a subcontractor but the arrangement looks like labour hire, your insurance obligations might be unclear. Get clarity on your status in writing.
How do I prove my tools are mine if they’re stolen?
Keep purchase receipts, serial numbers, and photographs of your tools. Store them somewhere you can access even if your phone is stolen — cloud storage or email them to yourself. For expensive items, consider engraving your driver’s licence number on them. Without proof of ownership, an insurer may reduce or deny a tools theft claim.
