Repair or write-off: who decides in NSW?

The assessor's role and the repair cost threshold

When you lodge a claim, the insurer appoints an assessor. That person inspects the car, often at a holding yard or your chosen repairer, and produces a report. The report lists the damage, the repair method, the parts required and the labour hours. Against that, the assessor applies the insurer's internal threshold.

Most insurers treat a car as an economic write-off when the repair cost reaches somewhere between 60 and 80 per cent of the car's market value. The exact figure is not published and varies between insurers. It is not a legal limit. It is a commercial decision the insurer makes to cap its exposure.

The assessor is not there to find the cheapest repair. They are there to determine whether repairing the car is economically sensible for the insurer. That distinction matters when you are dealing with a prestige car where parts alone can run into tens of thousands of dollars.

If you are unsure what stage your claim is at, our guide to dealing with insurers walks through the sequence from first notification to final decision.

What the assessor actually looks at

• Market value of the car at the time of the accident, not what you paid for it.
• Repair cost using new OEM parts where required.
• Labour hours at the insurer's agreed rate, which may be lower than your repairer's rate.
• Whether the damage is structural, and whether the car can be safely repaired.
• Salvage value, because a written-off car can be sold at auction.

If the repair cost plus salvage value exceeds the market value, the insurer will almost always write the car off.

Statutory vs economic write-off: the difference

NSW recognises two categories of write-off, and they have very different consequences.

Economic write-off

An economic write-off is a commercial decision. The insurer decides the repair cost is too high relative to the car's value, pays you the agreed value or market value, and takes ownership of the salvage. The car is recorded on the written-off vehicle register as a repairable write-off. It can be repaired and re-registered, but it must pass a heavy vehicle inspection and an identity check before it goes back on the road.

Statutory write-off

A statutory write-off is a safety and structural decision. The car has sustained damage that makes it unsafe or uneconomical to repair to a standard that would pass inspection. It is recorded as a statutory write-off and can never be re-registered in NSW. It can only be sold for parts or scrap.

The distinction is not about how much the repair costs. It is about whether the car can be brought back to a safe, roadworthy condition at all. A car with a bent monocoque and airbag deployment may be a statutory write-off even if the panels look repairable.

If your car has been declared a statutory write-off, our page on what happens next covers the steps from there.

For repairable write-offs, the process is different and our repairable write-off guide explains the inspection and re-registration path.

Why prestige cars are often repaired when cheaper cars are not

A prestige car holds its value better than a mainstream car, and that changes the maths. A 2021 BMW M3 Competition with low kilometres might still be worth a substantial sum. A repair that costs a third of that value is well inside the threshold, so the insurer repairs it.

The same repair cost on a ten-year-old hatchback might exceed the car's entire market value, so the insurer writes it off. The threshold is not about the damage. It is about the ratio.

Prestige cars also have a higher salvage value, which cuts both ways. A written-off M3 or RS 3 will attract bids at auction because the drivetrain and interior are worth money. That salvage value is factored into the write-off calculation, and it can push a borderline case over the line.

Parts availability is the other factor. A repair that requires a gearbox from Germany and a carbon fibre bonnet can take months. Insurers sometimes write off a car not because the repair is uneconomical but because the hire car costs during the delay would be. That is a real risk for prestige owners, and it is why parts delays matter.

If your car is being repaired rather than written off, you may be entitled to a like-for-like replacement while it is off the road. Our page on like-for-like explains what that means in practice.

When a replacement car is the natural next step, these are the kind of vehicles that match a prestige claim:

What your repairer can do to influence the outcome

Your repairer cannot override the assessor, but they can make the assessor's job easier and the repair case stronger. The most common reason a prestige car is written off unnecessarily is a thin or poorly documented repair quote.

A good repairer will:

• Strip the car enough to find hidden damage before quoting, not after.
• Photograph everything, including the damage behind panels and under the car.
• Quote using OEM parts and the correct labour hours for a prestige marque.
• Note any calibration or coding required, such as ADAS sensors or air suspension.
• Provide a realistic timeline, including parts lead times.

If the repairer is not an approved repairer for your marque, the insurer may push back. You have the right to choose your own repairer in NSW, but the insurer is only obliged to pay what a reasonable repair would cost. If your chosen repairer charges more than the insurer's preferred shop, you may be asked to cover the difference.

Our page on prestige repairer vs insurer preferred repairer covers how to handle that conversation.

If the car is repairable, the next question is how long it will take. Our guide to how long prestige car repairs take in Sydney gives realistic timeframes for common marques and repairs.

Getting a second opinion on the assessment

You are not obliged to accept the first assessment. If you believe the car is repairable, or that the market value is higher than the insurer has stated, you can get your own assessment.

An independent assessor, sometimes called a loss adjuster, will inspect the car and produce a report. That report can be used to challenge the insurer's figures. The cost is usually a few hundred dollars, but on a prestige car it can be the difference between a repair and a write-off.

You can also gather evidence of market value yourself. Look at comparable cars for sale in Sydney, including cars with similar kilometres and options. A 2016 BMW M3 Competition F80 with low kilometres is not the same as a high-kilometre example, and the insurer's valuation should reflect that.

If the car is already at a holding yard, you may need to arrange access for your assessor. Do this quickly, because some insurers move cars to auction within days of declaring a write-off.

How the decision affects your replacement car

If your car is being repaired, you may be entitled to a like-for-like replacement for the duration of the repair. That is not a courtesy car. It is a car of similar make, model and specification to yours, funded under credit hire if you are not at fault.

If your car is written off, the replacement car entitlement usually ends when the insurer settles. At that point you are shopping for a new car, not waiting for a repair. The distinction matters because the timeline and the paperwork are different.

For a repair, the hire car period is tied to the repair timeline. If parts are delayed, the hire car should continue. Our page on who pays for the hire car during repair delays covers that.

For a write-off, you may still be entitled to a replacement car for a short period while you source a new vehicle, depending on the circumstances and the insurer. Our page on buying a new car after a write-off walks through the options.

If you are weighing up whether to take a cash settlement instead of a repair, our cash settlement vs repair page sets out the trade-offs.

What to do if you disagree

Disagreement is common, and there is a process for it.

1. Ask for the assessment report in writing. You are entitled to see the basis of the decision, including the repair cost and the market value used.
2. Get your own assessment. An independent report is the strongest evidence you can bring.
3. Put your objection in writing. Email the insurer, state clearly what you dispute, and attach your evidence. Keep it factual.
4. Escalate internally. Ask for the dispute to be reviewed by a senior claims officer or the insurer's internal dispute resolution team.
5. Go to the Australian Financial Complaints Authority (AFCA). If the internal process does not resolve it, AFCA is free and binding on the insurer for claims up to its monetary limit.

Time limits apply. Do not sit on a decision you disagree with. If the car is moved to auction, recovering it becomes much harder.

If you are also dealing with a hire car claim that the insurer is disputing, our insurer disputes hire car claim page covers that overlap.

For fleets, the process is the same but the stakes are higher. Our fleet vehicle repair and write-off delays page is written for fleet managers.

Where to get advice

You do not need a lawyer for every write-off dispute, but you do need to know your rights. The following sources are useful:

• Your insurer's internal dispute resolution team. Start here. It is free and often resolves the issue.
• AFCA. Free, independent and binding on the insurer.
• An independent assessor. For valuation and repair cost disputes.
• A solicitor experienced in motor vehicle claims. For complex cases, statutory write-offs or where liability is disputed.
• NSW Fair Trading. For consumer issues relating to repairs and repairers.

This article is general information, not legal advice. If your circumstances are complicated, talk to a solicitor or your accountant before making decisions with financial consequences.
