NCAT Home Renovation Claim NSW: Defective Building Work

When a Renovation Goes Wrong

The kitchen renovation was supposed to take six weeks and cost A$28,000. Four months later, the builder has disappeared, the benchtops are crooked, and A$12,000 of progress payments are gone. Filing at NCAT can recover the money — but the first question is whether your dispute belongs in the Consumer and Commercial Division or the Home Building List.

The distinction matters because the Home Building List has its own rules, including a mandatory pre-filing step through NSW Fair Trading.

Consumer Claim or Home Building List?

Home Building List — NCAT hears disputes about residential building work through its Consumer and Commercial Division under the Home Building Act 1989 (NSW). Before applying, the dispute must first be referred to NSW Fair Trading and evidence of the investigation attached, unless an NCAT exemption applies. Do not choose the list based only on whether the work was structural or exceeded A$5,000.

Consumer and Commercial Division (general consumer claim) — use the general consumer-claim pathway for qualifying goods or services disputes that are not residential building work covered by the Home Building List.

If you are unsure which list applies, check whether the work is residential building work under the Home Building Act and review NCAT's current Home Building application requirements.

Building Your Case

Home renovation disputes are document-heavy. Gather these before filing:

1. The written contract — scope of work, price, payment schedule, start and completion dates. If there was no written contract, compile any text messages, emails or quotes that document what was agreed.
2. Payment records — bank transfers, receipts, invoices showing every progress payment made
3. Photographs — dated photos of the defective work, ideally alongside the contract specifications or original plans
4. Independent expert report — a building consultant or licensed builder (unconnected to the original contractor) who inspects the work and estimates the cost to rectify. The expert must comply with NCAT Procedural Direction 3 and include the Expert Code of Conduct declaration.
5. Correspondence — your complaints to the builder, their responses (or silence), any letter of demand you sent
6. Licence check — print the NSW Fair Trading licence search result for the builder, showing their licence number, class, and current status

What NCAT Can Order

For Home Building List matters, NCAT can make orders under the Home Building Act 1989 (NSW), including orders about payment for home building work and incomplete or defective work. Section 79N of the Fair Trading Act 1987 (NSW) provides remedies for consumer claims under Part 6A.

The Home Building List can hear building claims up to A$500,000 under section 48K of the Home Building Act 1989 (NSW). The A$100,000 limit applies to general consumer claims under Part 6A. For a higher-value building dispute, check the appropriate court forum before filing.

The Hearing

Renovation claims often involve competing expert assessments. The builder may bring their own expert who says the work meets industry standards. The tribunal member weighs both reports, examines the photographic evidence, and may ask questions about the scope of the original contract.

Come prepared with a clear summary of what was agreed, what was delivered, and the gap between the two — expressed in dollar terms using the independent expert's rectification estimate.
