Most jobs end fine. The hot water heater works, the deck is solid, the roof stops leaking. But every now and again the work doesn’t hold. The tile lifts, the wiring trips, the plumbing leaks behind the wall a fortnight later. The customer’s first instinct is usually a confused mix of frustration and politeness, like they’re not sure whether they’re allowed to be cross. Most people don’t actually know what their rights are when a tradie’s work fails, which is why so many small problems quietly become big ones.
Here’s a plain-language map of your rights as an Australian customer when a tradie’s job has gone wrong, what you can ask for, and what the law actually backs you up on.
The Australian Consumer Law applies to tradie work, not just shop products
A lot of Australians associate the Australian Consumer Law, the ACL, with refunds on toasters and faulty TVs. The same law applies to most tradie services. When you pay a plumber, electrician, builder or any other tradesperson, the work and any goods they install come with statutory consumer guarantees. These guarantees can’t be contracted out of, and they apply automatically. You don’t need a special clause in the quote. You don’t need to ask for them. They are part of the deal because the law puts them there.
The three guarantees that matter most
For tradie work, three ACL consumer guarantees do most of the heavy lifting. The service must be carried out with due care and skill. Any goods supplied as part of the service must be of acceptable quality and fit for purpose. And the work must be reasonably fit for any purpose the customer made known to the tradie. Translated into normal language: the tradie has to do the job competently, the parts they install have to actually work, and the result has to do what you both agreed it would do. Those three lines underpin most consumer remedies you can seek.
Minor fault vs major fault changes everything
The ACL distinguishes between a minor problem and a major one, and the difference dictates what you can demand. A minor fault is something the tradie can put right within a reasonable time. A major fault is something more serious: the work is so far below what you reasonably expected that it can’t be easily fixed, the goods are completely unsafe or won’t do their basic job, or the failure is one a reasonable customer would not have agreed to in advance. For a minor fault, the tradie usually gets the chance to come back and fix it. For a major fault, you can demand a refund, a replacement, or compensation in addition to repair.
Repair, replacement and refund are all on the table
For a minor problem, the practical first step is to give the tradie a chance to come back and fix the work. They are entitled to that opportunity, and you generally have to give it to them in good faith. For a major problem, you have a stronger hand. You can require the work to be redone properly, you can ask for a refund of some or all of the cost, or you can recover any reasonable compensation for the time and money you spent putting the failure right. Pick the remedy that actually fits your situation.
You don’t lose your rights because the warranty period “ended”
Tradies sometimes wave a warranty card and say your 12-month warranty has expired, sorry. A written warranty offered by the business sits on top of your ACL rights, not in place of them. The consumer guarantees apply for a reasonable period, which in residential building work is often years, not months. A roof that fails after 14 months is still a problem the customer can pursue. The fact that the laminated warranty card said 12 months is not the end of the conversation. It might be the start of one.
State-level building consumer protections matter too
Outside the ACL, every state and territory has its own residential building consumer protection scheme: the Domestic Building Contracts Act 1995 in Victoria, the Home Building Act 1989 in NSW, the Domestic Building Contracts Act 2000 in Queensland, and similar acts in WA, SA, Tasmania, ACT and NT. These add statutory warranties for residential building work that typically run for several years for major defects and a shorter period for minor ones. The customer doesn’t have to choose between ACL rights and state-level rights. Both apply in parallel.
Document everything before you do anything else
Before you write a single demand letter or hit a single online review, document the problem. Photos with timestamps. Videos showing the fault. Copies of the quote, the invoice and any messages. A written log of when the problem first appeared. This evidence costs you nothing in the moment and makes the difference between a clean dispute and a he-said-she-said. If the dispute eventually goes to fair trading, VCAT, NCAT or QCAT, the side with the cleaner record almost always lands better.
Give the tradie a fair chance to fix it before going public
Even when the law is plain on your side, jumping straight to a public review or a regulator complaint is rarely the most effective opening move. A short written message, calmly describing the problem and asking the tradie to come back and put it right, usually moves things faster than a public dispute. It also strengthens your position if the matter does escalate, because you can show you tried. The law expects a reasonable opportunity to remedy. The tradie also generally prefers it, because the alternative is more expensive for everyone.
When to escalate to fair trading
If the tradie ignores you, denies the problem, or the work is clearly a major fault they will not address, your state or territory consumer protection or building regulator is the next step. NSW Fair Trading, Consumer Affairs Victoria, the Queensland Building and Construction Commission, the Building Practitioners Board in WA, and equivalents elsewhere all run free dispute and conciliation services for residential building and tradie work. They are not perfect, but they are designed for exactly this situation, and they are usually faster and cheaper than starting in court.
Your rights as a customer when a tradie’s job goes wrong are stronger than most people realise. The ACL gives you statutory guarantees on the work and on the parts. State consumer law adds longer-term residential warranties. Document the problem, give the tradie a fair chance to fix it in writing, and escalate to your regulator if they won’t. Knowing the rules makes the conversation calmer, not more aggressive, because you no longer have to argue from feelings alone.
