Commercial Motor Insurance

Insurers use a set of rating factors to determine the cost of a commercial motor vehicle policy. The vehicle itself — year, make, and model — plays a significant role, as some vehicles are more expensive to repair and others carry higher risk due to performance engines. The insured value of the vehicle affects premiums directly — the more the insurer would have to pay on a total loss, the higher the premium. The garaging address also matters — your overnight postcode carries claim statistics around theft, storm damage, and accident frequency that influence your rate. Finally, driver age and history are heavily weighted — young drivers under 25 attract significantly higher premiums, and a poor claims history will increase your costs.

There are several practical steps that can reduce your commercial motor insurance premium without sacrificing protection. Review your vehicle's insured value annually — many operators set a sum insured years ago and never update it, meaning they are paying premiums on a value higher than the current market value. Adjust your radius limit to reflect where your vehicle actually travels — insuring for a 500km radius when you only operate within 100km of your base is adding unnecessary cost. Review your listed drivers and remove any under-25s who no longer drive the vehicle. Review listed accessories — most policies automatically cover accessories up to $5,000, so you may not need to list items separately. And if cash flow allows, paying annually rather than monthly removes the instalment loading which typically adds around 10% to your premium.

This is one of the most important clauses on a commercial motor policy and one that many operators overlook. When your policy states your vehicle is insured for $X or market value — whichever is lesser, it means that even if you nominate a higher figure, the insurer will only pay the market value of the vehicle at the time of the loss if that is the lower amount. If your truck was insured for $150,000 but is only worth $100,000 at the time it is written off, you will receive $100,000 — not $150,000. There is no rebate for over-insuring, but you pay premiums on the higher figure. This is why reviewing your vehicle's insured value each year to account for depreciation is important — it keeps your premiums aligned with the actual risk and avoids paying for cover that will never pay out at the nominated amount.

Yes — in most cases, voluntarily increasing your excess will reduce your premium. An excess is the amount you contribute toward a claim before the insurer pays the rest. On most commercial motor policies, the standard excess is around $600 for standard vehicles, though for larger or higher-value vehicles the excess is often calculated as a percentage of the sum insured — commonly 1%. By electing to carry a higher excess you are sharing more of the financial risk with the insurer, which reduces the premium they charge. The right excess level depends on your cash flow and how frequently you make claims — a broker can model the premium impact of different excess levels so you can make an informed decision.

If you operate a small business in New South Wales with an annual turnover of less than $2 million, you may be eligible for the NSW Stamp Duty Exemption on your commercial motor insurance. This exemption can reduce your premium by close to 10% and applies to commercial motor vehicle policies among other insurance types. Eligibility is determined by Revenue NSW — check the Small Business Exemption section in the Revenue NSW FAQ and the Insurance Duty factsheet at revenue.nsw.gov.au to confirm whether your business qualifies. If you are eligible, your broker can apply the exemption to your policy at renewal or inception.

Paying your commercial motor insurance premium annually rather than in monthly instalments is one of the simplest ways to reduce the total cost of your cover. Monthly instalment arrangements typically add around 10% to the total premium over the course of the year — which on a significant commercial motor policy can be a meaningful additional cost. If your cash flow allows it, paying annually removes this loading entirely. That said, if monthly payments genuinely alleviate cash flow pressure during the year, the convenience may be worth the additional cost. A broker can also explore premium funding arrangements that spread the cost without the same loading as standard monthly instalments.

A commercial motor insurance broker accesses a large panel of approved insurers on your behalf, approaching multiple providers to ensure the premium you receive is genuinely competitive for your circumstances. Going direct limits you to one insurer's products and one set of policy terms. A broker also reviews your existing policy for cost-saving opportunities — vehicle values, radius limits, driver lists, accessories, excess levels, and stamp duty exemptions — that most operators miss when renewing directly. The process does not cost you more in most cases, as brokers are remunerated by the insurer. You get expert review, genuine market comparison, and a better chance of paying the right premium for the risk you actually represent.
