Your Subbie's QBCC Licence Doesn't Cover the Work: A Head Contractor's Survival Guide
Key Takeaways
If your subcontractor works outside their licence class, you can lose your own head contractor exemption and be treated as the unlicensed party—the protection sits in Schedule 1A of the Queensland Building and Construction Commission Act 1991.
You may be able to lawfully withhold payment: an unlicensed subcontractor loses their statutory entitlement to be paid under section 42(3) of the QBCC Act, which changes how you respond to a progress claim.
Contractual "pay when paid" clauses designed to delay subcontractor payments are void under section 74 of the Building Industry Fairness (Security of Payment) Act 2017 (BIF Act) and cannot be relied upon to manage the fallout of licensing breaches.
Suspending a subcontractor's works requires strict adherence to the subcontract's default and termination provisions to avoid risks of repudiation and wrongful termination claims.
You are standing on a residential development in Brisbane when the principal's superintendent hands you a notice—not for a failed inspection or an out-of-tolerance batter angle, but because the subcontractor building your structural retaining walls is operating outside their specific QBCC licence class. The crew is still setting reinforcement, the next progress claim is due in three days, and you are suddenly exposed to the reality that relying on an unlicensed subbie might have just stripped away your own legal right to carry out the project. This article delivers the exact triage sequence you need to assess the site breach, adjust your payment schedule obligations, and handle the subcontractor's removal without triggering a wrongful termination dispute.
Immediate Steps When a Civil Subcontractor Lacks the Correct QBCC Licence Class
The site cannot afford a three-week delay, but allowing non-compliant works to continue can jeopardise your entire enterprise and insurance response. At this stage, you need a clear sequence of actions to take today to contain your exposure before the regulator or the principal forces your hand. This section provides the exact triage process to assess the breach, verify the scope discrepancy, and determine whether a stop-work directive is required.
Separating Statutory Licensing Breaches from Contractual Termination Rights
Your first instinct may be to lock the subcontractor out of the site the moment you discover the breach. Resist it. A statutory breach by the subcontractor is an offence under the legislation, but it operates distinctly from your private contractual rights. A regulatory violation does not inherently grant you the right to end the commercial agreement unless the contract itself maps that statutory failure to a termination right.
A civil subcontractor's breach of Queensland's statutory licensing requirements does not automatically trigger a contractual right for the head contractor to terminate, unless the subcontract expressly categorises the licensing failure as a default event.
If you react to the licensing defect by terminating the relationship without pointing to a specific default clause, you can expose your business to claims for wrongful termination and repudiation. Resolving contractual termination disputes requires navigating both the default provisions of the subcontract and the evidentiary burden of proving the breach actually occurred.
Verifying the Subcontractor’s Specific Licence Scope
Before issuing any formal notices or stop-work directives, you must confirm the discrepancy between the subcontractor's licence class and the physical work they are executing. Factual verification protects your position if the subcontractor later challenges your directions.
Cross-reference the subcontractor’s entity name and ABN directly on the QBCC Online Licence Search Tool to confirm their current, active licence classes.
Review the specific scope limitations of their approved class using a reliable QBCC Licence Search methodology to ensure they are not exceeding their permitted tier or category.
Compare the statutory definition of their licence class against the actual site activities underway today (e.g., distinguishing between restricted structural landscaping and broad civil earthworks).
Document any site activities that clearly fall outside the subcontractor's verified scope, gathering photographs and site diary entries as evidence.
The Cost of Delay vs the Risk of Regulatory Intervention
Warning: Allowing an unlicensed subcontractor to continue working on your site in order to meet a project deadline exposes your company to severe regulatory scrutiny and potential site shutdowns under the Queensland Building and Construction Commission Act 1991 (Qld). While halting the earthworks causes immediate commercial friction and project delay, turning a blind eye to the licensing defect can invite the regulator onto your site. In practice, a tip-off from a disgruntled worker or a diligent principal can prompt QBCC attention, and the regulator has enforcement powers that, if exercised, can disrupt a project for far longer than a managed subcontractor replacement would.
Every hour an unlicensed crew stays on the tools, your exposure compounds. Instruct our construction team to triage the breach today and secure your commercial position before the regulator makes the decision for you.
How the Unlicensed Subcontractor Threatens Your Head Contractor Exemption
The immediate site chaos is one thing, but the regulatory knock-on effect is the real danger to your business structure. If you are operating as an unlicensed civil head contractor relying on the statutory exemption, that protection is fragile. This section breaks down exactly how the subcontractor's licensing failure removes your legal shield and exposes you to direct penalties.
Your Exemption Depends on Your Subbie's Licence
Many civil contractors operate as the principal or head contractor on commercial sites without holding a comprehensive builder's licence themselves, relying instead on the statutory protection found in Schedule 1A, s 8 Head contracts to carry out building work. This provision allows an unlicensed person to lawfully enter into a contract to carry out non-residential building work. However, the exemption contains a strict prerequisite regarding the supply chain.
Under Schedule 1A of the QBCC Act, a civil head contractor’s exemption from holding a builder's licence relies strictly on engaging a subcontractor who holds the appropriate class of licence for the physical building work.
If the subcontractor performing the work lacks the precise licence class required for the tasks they are executing, the foundation of your head contractor exemption falls away. The legislation offers no grace period for an honest hiring mistake; the exemption simply stops applying to you for that scope of work.
We see this play out on Queensland civil sites more often than most head contractors expect — frequently uncovered only when a principal's superintendent or the QBCC starts asking questions mid-project. Our team has guided head contractors through the exact moment the exemption falls away, working through the in-force text of Schedule 1A and any subordinate regulations as at the relevant date before advising on next steps. The practical difference is rarely the legislation itself; it is whether the response is sequenced correctly from the first notice onward.
It is also important to appreciate that this exemption is not a permanent fixture. It was previously slated for abolition under reforms first moved in 2020, before the Building and Other Legislation Amendment Act 2022 (Qld) preserved it. However, that legislation introduced a regulation-making power enabling the Government to require particular head contractors to hold a licence and to prescribe circumstances in which the exemption does not apply, for example in relation to high-risk classes of work.
The exemption therefore remains in force, but it is technical, conditional, and subject to change by subordinate regulation. Before you rely on it for a live matter, you should confirm the current in-force text of Schedule 1A and any regulations made under it as at the relevant date.
QBCC Penalties for the Head Contractor Undertaking Unlicensed Building Work
When the exemption fails because your subcontractor is improperly licensed, the regulator stops looking at them and starts looking at you. Without the protection of Schedule 1A, you are assessed against the primary prohibition in s 42 Unlawful carrying out of building work.
Section 42(1) explicitly states that, unless exempt under Schedule 1A, a person must not carry out, or undertake to carry out, building work unless they hold a contractor's licence of the appropriate class. By entering into the contract with the principal and failing to satisfy the exemption through a compliant subcontractor, you are deemed to be carrying out unlicensed contracting.
The regulator can issue infringement notices and prosecute you directly for this breach, regardless of whether you ever touched a machine on site. Section 42 carries escalating maximum penalties, with higher penalties for repeat offences and the possibility of imprisonment for a third or subsequent offence, or where the work is tier 1 defective building work; a company can be liable to a multiple of the maximum applying to an individual. Because the dollar value of a penalty unit is adjusted from time to time, you should confirm the current figures rather than relying on a fixed dollar amount.
Practitioner Insight: When Site Interference Voids Your Exemption
Expert insight: Head contractors acting as principals often inadvertently void their exemption not by hiring the wrong subbie, but by getting their hands dirty on site. The exemption assumes you are coordinating, not building. In practice, the line gets crossed in mundane, easily overlooked ways: a director who jumps on the excavator to "show the operator the right batter angle," a project manager who personally sets out levels and pegs the trench lines, or a head contractor's staffer who directs the sequence and method of compaction rather than simply telling the subcontractor what end result the contract requires.
The distinction adjudicators and inspectors tend to draw is between managerial direction (what is to be done, by when, to what specification) and the physical or technical execution of the building work itself (how each task is performed, hands-on). The former is consistent with the exemption; the latter looks like contracting to carry out, and personally carrying out, building work.
The risk multiplies when the head contractor's people fill gaps left by an under-resourced subbie. If your site supervisor starts operating plant, fixing formwork, or making the on-the-spot engineering calls that the licensed contractor is supposed to make, you have likely stepped outside the protection of Schedule 1A for that scope of work—even though you genuinely believed you were just "helping the job along." A useful self-test before you intervene: am I telling them what the contract requires, or am I doing their licensed work for them? If it is the latter, stop, document the deficiency, and address it through the subcontract rather than the shovel.
Withholding Progress Payments and Statutory Entitlements
The end of the month is approaching, and the unlicensed subcontractor has just served a massive progress claim for the disputed works. You are caught between preserving cash flow and breaching the BIF Act. This section outlines your payment obligations, the subcontractor's lost statutory rights, and the void clauses you cannot rely on to delay payment.
The Subcontractor's Loss of Entitlement to Monetary Consideration
A payment claim from an unlicensed subcontractor triggers a familiar panic about strict BIF Act timelines. What that panic obscures is that the QBCC Act has already altered the subcontractor's underlying right to be paid. Section 42(3) explicitly dictates that a person who carries out building work in contravention of the licensing requirements is not entitled to any monetary or other consideration for doing so.
Under section 42(3) of the QBCC Act, a civil subcontractor who carries out building work without the appropriate licence class loses their statutory entitlement to monetary consideration for that specific work.
If you receive a payment claim from a non-compliant subcontractor, you must still provide a valid payment schedule within the strict statutory timeframe. However, you can rely on the section 42(3) disentitlement as a primary reason for withholding payment in that schedule. Failing to include this specific jurisdictional defence in your payment schedule can limit your ability to raise it later during an adjudication response, which is why getting the payment schedule right at the outset is critical to framing the dispute in your favour.
A payment schedule that omits the section 42(3) point can quietly forfeit your strongest defence before the dispute even begins. Request an urgent review of your draft schedule from our team while the statutory clock is still running.
Why Disguised "Pay When Paid" Clauses Will Not Protect the Head Contractor
A common reflex is to delay payment by pointing to back-to-back clauses in the subcontract, arguing you do not have to pay the subbie until the principal pays you. This tactic is legally void. Under s 74 Effect of 'pay when paid' provisions of the BIF Act, any contractual clause that conditions a subcontractor's payment upon the head contractor receiving payment from the principal has no effect in relation to construction work.
Section 74 provides that a "pay when paid" provision of a construction contract has no effect in relation to any payment for construction work carried out, or related goods and services supplied, under the contract. In other words, the prohibition is engaged precisely because the relevant work answers the description of construction work under the Building Industry Fairness (Security of Payment) Act 2017 (Qld); the clause only retains any operation to the extent the work falls outside that definition. Adjudicators regularly strike down provisions disguised as "pay if certified" or condition precedent clauses. You cannot rely on a void payment term to manage the financial fallout of an unlicensed subcontractor; you must address the licensing defect head-on in your payment schedule.
Practitioner Insight: The Limits of Quantum Meruit Claims for Unlicensed Civil Works
Expert insight: When a head contractor denies a progress claim citing a section 42 breach, unlicensed subcontractors often threaten to bypass the contract entirely and claim the full project value in quantum meruit. It is worth being precise about the forum here: section 42(4) of the QBCC Act frames the reasonable remuneration exception as a power of the court, not QCAT, so the disentitlement and any recovery argument are ultimately resolved by reference to that curial power rather than assumed to sit within the tribunal's jurisdiction. While section 42(4) does provide a narrow exception allowing the court to award reasonable remuneration, this pathway is strictly limited—and in practice the gap between what the subbie claims and what they can prove is where these disputes are won or lost.
The recovery under section 42(4) is generally confined to amounts the subcontractor has actually paid out in supplying materials and labour, with the express carve-outs that it cannot include an allowance for the supply of the subcontractor's own labour, nor any allowance for profit. That means the evidentiary burden sits squarely on the subcontractor, and it is a documentary burden, not a narrative one. A court is unlikely to be moved by a lump-sum figure pulled from the contract price. It wants to see the actual cost trail: supplier invoices for fill, aggregate and pipe; plant hire dockets or internal plant costing records; timesheets matched to wage records for engaged or employed labour (as distinct from the operator's own labour, which is not recoverable); and fuel and consumables receipts.
The recurring weakness on the subcontractor's side is that civil operators frequently price work on a rate or lump-sum basis and never keep cost-level records, so when pressed to substantiate raw expenditure they simply cannot. Where the records are thin or reconstructed after the fact, the recoverable figure tends to shrink well below the claimed amount, and items dressed up as "site overheads," "supervision," or "establishment" are routinely treated as disguised profit or margin and stripped out. Practically, the head contractor's strongest position is to take the disentitlement point cleanly in the payment schedule and then force the subcontractor to prove every dollar of raw cost line by line, rather than conceding any global valuation.
Managing Subcontractor Suspension and Replacement Safely
Removing the non-compliant subcontractor is necessary to save the project, but executing that removal poorly creates massive secondary liability. You need to sequence the suspension, capture the site evidence, and engage the replacement civil contractor without handing the defaulted party a wrongful termination claim. Here is the framework for a lawful exit.
Invoking Subcontract Suspension or Termination Provisions
Discovering that your subcontractor lacks the appropriate licence does not give you an unconditional right to change the padlocks on the site gates tomorrow morning. You must look to the specific default and suspension provisions drafted into your subcontract.
Before terminating a civil subcontractor for a QBCC licensing breach, the head contractor must issue formal default notices in strict compliance with the subcontract's termination timeframes to mitigate the risk of repudiating the agreement.
If you lock an unlicensed subcontractor out of the site without following the contractually mandated show-cause or default notice periods, a tribunal or court may determine that your actions constitute repudiation of the contract. This outcome can entitle the subcontractor to claim damages for wrongful termination, overshadowing the initial licensing defect. Default notices drafted to align with both the subcontract terms and the reality of the statutory breach are what keep the termination process defensible.
In our work with head contractors across Queensland and New South Wales, the wrongful termination claim is almost always self-inflicted — the result of locking a subbie out first and reading the default clause second. We routinely draft the show-cause and default notices that thread the gap between a genuine licensing breach and the strict contractual machinery the subcontract demands. Done properly, the same set of facts that exposes the subcontractor becomes the foundation of a clean, defensible exit rather than a damages claim against you.
Evidentiary Requirements Before Engaging a Replacement Civil Contractor
Once the non-compliant subcontractor is lawfully suspended or removed, the pressure to mobilise a replacement crew and recover lost time is intense. However, allowing a new contractor to commence work without first securing comprehensive site evidence is a critical error.
Before the replacement contractor alters the site, you must document the exact percentage of completion and the specific condition of the works left by the departing subcontractor. This involves engaging independent surveyors or engineers to capture the site state. Without that evidentiary baseline, it becomes exceedingly difficult to defend against the outgoing subcontractor's later claims for unpaid variations, or to justify the back-charges you intend to levy for rectification work.
Conclusion
Standing on that half-completed Brisbane subdivision with the superintendent's notice in hand is a high-pressure moment, but it does not have to mean the end of your project or your business. Discovering your earthworks subcontractor lacks the correct QBCC licence class presents an immediate threat to your site compliance and your own head contractor exemption, but it is a manageable crisis if handled methodically.
You now know that a statutory licensing breach does not automatically give you a free pass to ignore your contract's termination procedures. You also understand that section 42(3) of the QBCC Act strips the unlicensed subcontractor of their right to monetary consideration—giving you a powerful, lawful basis to withhold payment through a compliant payment schedule, rather than relying on void "pay when paid" clauses.
Before you order the subcontractor's machinery off the site or draft your next payment schedule, your immediate next step is to pull the specific default and suspension clauses from your subcontract and cross-reference them against a fresh, timestamped QBCC licence search. Documenting the exact scope discrepancy today is what will protect your balance sheet tomorrow.
The catch is that the two clocks now running—your BIF Act payment schedule deadline and your contractual notice periods—do not pause while you work out your position. Getting your payment schedule and default notices reviewed before you act is the difference between a managed exit and a damages claim. If you are facing this on site right now, contact our construction team today and we will help you sequence the next 72 hours correctly.
FAQs
Do I lose my head contractor exemption if my civil subcontractor is unlicensed?
Yes, you may lose the protection of the head contractor exemption under Schedule 1A of the Queensland Building and Construction Commission Act 1991. The exemption strictly requires that the physical building work is carried out by an appropriately licensed contractor. If your subcontractor lacks the correct licence class for the work they are performing, you can be deemed to be carrying out unlicensed building work yourself.
Do I have to pay a Queensland civil subcontractor who does not have the right QBCC licence?
You can usually withhold payment lawfully, because section 42(3) of the QBCC Act states that a person carrying out building work in contravention of licensing requirements is not entitled to monetary consideration. However, you must still issue a valid payment schedule under the Building Industry Fairness Act within the strict statutory timeframe outlining this jurisdictional defence. A court or adjudicator may still award limited reasonable remuneration restricted strictly to raw materials and labour.
Can I instantly terminate my civil subcontractor if I find out they are unlicensed?
No, you typically cannot terminate the subcontractor instantly unless your specific subcontract explicitly defines a statutory licensing breach as an immediate termination event. You must follow the formal default and show-cause notice periods outlined in your contract. Locking them out without following these procedural steps may expose you to claims for wrongful termination and repudiation.
Are "pay when paid" clauses enforceable in Queensland civil construction contracts?
No, contractual clauses that condition a subcontractor's payment upon the head contractor receiving funds from the principal are void for construction work. Under section 74 of the Building Industry Fairness (Security of Payment) Act 2017, these provisions have no legal effect. Head contractors must address defective or unlicensed work directly in a payment schedule rather than relying on back-to-back payment delays.
What is the penalty for a head contractor undertaking unlicensed building work in QLD?
A civil head contractor operating without the protection of the Schedule 1A exemption may face significant penalties under section 42 of the QBCC Act. The Queensland Building and Construction Commission can issue infringement notices, apply demerit points where the offender is a licensee, or pursue direct prosecution. The specific penalty exposure typically depends on the severity, financial value, and duration of the unlicensed contracting, and the maximum penalties escalate for repeat offences.
What should I do before replacing an unlicensed civil subcontractor on a Queensland site?
Before allowing a replacement contractor to commence work, you should comprehensively document the site's condition and the exact percentage of completion left by the outgoing subcontractor. Engaging an independent surveyor or engineer to capture this evidentiary baseline is highly recommended. This evidence can support your position if the suspended subcontractor later disputes back-charges or claims unpaid variations.
