How do I write a callback and warranty policy into my trade quotes?

Add a callback and warranty clause to every quote that states your state's statutory warranty period, defines what a defect covers versus new scope, sets a response timeframe, and requires written notice from the customer. Statutory warranty periods vary by state: NSW carries a six-year warranty for major defects and a two-year warranty for other defects, running from practical completion, while Victoria extends to ten years for structural work. Your clause references your state's specific periods so the customer knows the rules before work starts.

This guide gives you the clause wording, the state-by-state periods, and the practical steps to communicate the policy so it actually gets read. For the pricing side of callbacks, including how to calculate a warranty reserve for each quote, see our guide to pricing callbacks into your quotes. For managing callbacks day to day without losing money, see our callback management guide.

Why does a written callback policy matter more than a verbal promise?

A verbal agreement to "come back and fix anything" sounds reasonable on site. The problem surfaces months later when the customer's definition of "anything" includes work you never quoted. Without a written boundary, you have no documented record of what your warranty covers, what it excludes, and how the customer should raise a claim.

The Australian Competition and Consumer Commission states that "Services must be provided with due care and skill, be reasonably fit for purpose, and be provided within a reasonable time." Those consumer guarantees apply regardless of what your quote says. A written callback policy does not replace them. It sits alongside them, giving both parties a clear process for the claims that fall within your warranty obligations and a defined boundary for everything that does not.

The practical benefit: when a customer calls about a crack or a leak, you check the policy, confirm the job date, and respond within your stated timeframe. No argument about what was promised. No guessing whether this is a defect or new scope. The clause did the work months ago.

What are the statutory warranty periods by state?

Every Australian state and territory imposes minimum warranty periods on residential building work. These are non-excludable: your quote clause can reference them but cannot shorten them. The periods below are the statutory minimums under each jurisdiction's building legislation.

Victoria stands out with a ten-year structural warranty, the longest in Australia. Queensland triggers the written-contract requirement at $3,300 including GST, the lowest threshold nationally. These differences matter: a plumber in Brisbane needs a written contract on almost every residential job, while a painter in Hobart should check their state's threshold with Consumer Affairs Tasmania.

Your quote clause should name your state's specific periods. Writing "standard warranty applies" is vague and unhelpful in a dispute. Writing "structural defects: 6 years from practical completion per NSW Home Building Act 1989" is specific, verifiable, and harder to argue with.

What should a callback and warranty clause actually include?

A practical clause covers six elements. Each one addresses a specific dispute pattern that tradies encounter after handover.

• Warranty period reference. State the applicable statutory warranty period for your jurisdiction. Name the legislation. Do not invent a shorter period: any term that purports to exclude or limit the statutory warranty is void under Australian Consumer Law.
• Definition of a defect. A defect is work that does not meet the standard it was contracted to, or that fails to comply with the relevant Australian Standard, Building Code, or manufacturer specification. Spell this out so the customer can see the line between a defect (your responsibility) and normal wear, misuse, or damage by a third party (not your responsibility).
• Written notice requirement. Require the customer to notify you in writing (email or text message is sufficient) describing the issue, when it appeared, and attaching photos if possible. This creates a documented trail and filters out the "I mentioned it to you at the shops" conversation that you have no record of.
• Response timeframe. State how quickly you will inspect a reported defect once written notice is received. A common range is 5 to 15 business days for a non-urgent defect, with a separate emergency provision for safety-critical issues.
• Exclusions. List what the warranty does not cover: damage caused by the customer or a third party, normal wear and tear, failure to maintain in accordance with your handover instructions, unauthorised modifications, and issues arising from building movement or structural settlement outside your scope of work.
• Inspection cost for non-defect callouts. If you inspect a reported issue and it turns out to be caused by the customer, a third party, or wear rather than a defect in your work, state that you will invoice for the inspection at your standard rate. The customer sees this before signing, so there is no surprise if a callout turns into a billable visit.

How do I separate a defect from normal wear or customer damage?

This is where most callback disputes start. The customer says the paint is peeling. You say the room was not ventilated as advised. Without a documented definition and handover notes, it becomes a word-against-word argument.

Your policy draws the line in three places:

• Defect. Work that does not meet the contracted standard, the relevant Australian Standard, or the manufacturer specification at the time it was completed. A cracked tile within six months where the substrate was your responsibility is a defect.
• Wear and maintenance. Deterioration from normal use over time. Grout discolouration in a wet area after two years of daily use is wear, not a defect, provided the grout was correctly applied and sealed at handover.
• Customer or third-party damage. A drilled hole through a waterproofing membrane, a heavy impact on a benchtop, or plumbing modifications by another tradesperson after your work was completed. Your policy excludes these explicitly.

The handover documentation you give the customer, including care instructions, product data sheets, and dated photos of the finished work, is the evidence that supports this distinction later. For a deeper look at how to log and manage callbacks when they come in, see our callback management guide.

How do I communicate the policy so customers actually read it?

A clause buried on page four of the terms and conditions has legal standing but zero practical value if the customer never reads it. Three steps make the policy visible:

• Quote cover summary. On the first page of your quote, include a one-line summary: "This quote includes a callback and warranty policy (see clause X) covering defect rectification for the statutory period." The customer sees the policy exists before they reach the detail.
• Walkthrough at sign-off. When the customer signs the quote, point to the clause and explain it in plain language: what it covers, what it does not cover, how to raise a claim. This takes sixty seconds and prevents the "I didn't know about that" conversation later.
• Handover pack reference. At practical completion, include a copy of the callback clause in the handover pack alongside the care instructions, product sheets, and warranty certificates. The customer has everything in one place when they need it months later.

If you use a job management app like ServiceM8, Tradify, or Fergus, attach the policy as a standard template that auto-populates into every quote. This removes the risk of forgetting it on one job and creating an inconsistency that a customer can point to later.

What if the customer disputes whether an issue is a defect?

Your policy should include a dispute resolution step before either party escalates. A practical sequence:

• Inspection. You attend the site within the stated response window and document the issue with photos and notes.
• Assessment. You compare the reported issue against the original scope, the relevant standard, and your completion photos. If it is a defect, you rectify it within a stated timeframe at no charge. If it is not, you provide a written explanation and, if the customer wants the work done anyway, issue a separate quote as new scope.
• Independent assessment. If the customer disagrees with your finding, the policy can state that either party may engage an independent building inspector at their own cost, with the losing party reimbursing the inspection fee.
• Fair Trading or tribunal. If the matter cannot be resolved, the customer retains the right to lodge a complaint with their state's Fair Trading body or the relevant building authority, or to take the matter to the state's civil and administrative tribunal. Your policy should acknowledge this right explicitly. Omitting it does not remove it, and including it shows the customer you are operating transparently.

For work above the relevant threshold, The statutory maximum ACL civil penalty for companies is the greater of $100,000,000, three times the benefit obtained, or 30 percent of adjusted turnover for the breach period (statutory maximum for companies, conduct on or after 28/03/2026). A clear, honest warranty clause is not just good practice: it is the documented evidence that you set fair expectations from the outset. This guide is general information for Australian trade businesses, not legal advice. For advice on your specific situation, consult a qualified lawyer or your state building authority.

How does this interact with home warranty insurance?

Home warranty insurance (also called domestic building insurance or building indemnity insurance) is a separate layer. It protects the homeowner if the builder dies, disappears, or becomes insolvent, leaving work incomplete or defective. It does not replace your callback policy: the insurance covers catastrophic contractor failure, while your policy covers day-to-day defect rectification while you are still operating.

The threshold at which home warranty insurance becomes mandatory varies sharply by state. Queensland's Home Warranty Scheme applies from $3,300 including GST, the lowest trigger nationally. NSW, SA, WA and Tasmania set theirs at $20,000. Victoria sits at $16,000. If your work exceeds the threshold, you must have the policy in place before taking any payment or starting work. For a detailed breakdown, see our guide to home warranty insurance.

Your callback clause and your home warranty insurance serve different purposes. Include a line in the clause clarifying: "This callback and warranty policy covers defect rectification by [Business Name]. Where required by law, home warranty insurance has been obtained separately and a certificate will be provided before work commences."

What about the non-excludable consumer guarantees?

Australian Consumer Law provides consumer guarantees that apply to every trade service regardless of what your quote says. These are non-excludable: any clause that attempts to limit or override them is void.

The guarantees most relevant to trade work are:

• Due care and skill. The work must be done to a competent standard.
• Fit for purpose. Where the customer makes their purpose known, the work must achieve it.
• Reasonable time. The work must be completed within a reasonable timeframe.

Your callback policy sits alongside these guarantees, not above them. A well-drafted clause acknowledges them explicitly: "Nothing in this policy excludes, restricts or modifies any right or remedy the customer may have under the Australian Consumer Law or the applicable state building legislation." This one sentence protects you from a claim that your clause was misleading by implication.
