What Voids a Machinery Insurance Claim

What Machinery Insurance Typically Covers

Machinery insurance, often called plant and equipment insurance, is designed to cover physical damage to your machines from sudden and accidental events. This can include damage from collision, rollover, fire, theft, and third-party liability arising from machine operation.

What it doesn't cover is just as important. Most policies exclude damage arising from overloading, unlicensed operation, use outside the machine's intended purpose, and gradual deterioration or deferred maintenance. Mechanical breakdown is generally a separate cover type.

Policies vary significantly between insurers. Some offer broader protection for owners when an operator breaches a condition without the owner's knowledge. Others don't. The wording matters, and it's worth having a broker read it properly, not just the summary page.

This is general information only. Talk to your broker about what applies to your specific machines and operations.

What Affects Your Machinery Insurance Premium

Several factors influence what you'll pay for machinery cover. Understanding them helps you make informed decisions, and avoid paying for the wrong policy.

• Machine type and value: Higher-value or specialised equipment typically attracts higher premiums. The sum insured needs to reflect current replacement cost, not purchase price.
• How the machine is used: Operating environment, industry, and whether the machine is used for hire all affect the risk profile and premium.
• Operator qualifications: Policies that cover a broader range of operators, or machines hired out to third parties, generally carry higher premiums to reflect the increased exposure.
• Claims history: A history of prior claims, particularly for similar incidents, will affect both premium and the terms insurers are willing to offer.
• Maintenance standards: Insurers assess how well equipment is maintained. Well-documented service histories can support more favourable terms.
• Location and storage: Where machines are kept when not in use, secured yard, open site, remote location, affects theft and damage risk.

Your Machinery Insurance Claim Got Declined. Here's Why That Happens.

Most plant owners don't think about their machinery insurance until something breaks, tips over, or catches fire. That's understandable, you're running a business, not a policy review committee. But when a machinery insurance claim gets declined, the financial hit can be devastating. A machine worth several hundred thousand dollars. A job site shut down. And an insurer telling you they won't pay.

It does happen.

The frustrating part? Most declined claims come down to things that could have been caught beforehand, a policy condition that wasn't met, a disclosure that was missed, or a use case the policy never actually covered. Not fraud. Not negligence in the dramatic sense. Just gaps between what owners assume their policy does and what it actually says.

At Gerrards, we come across this. So here's a plain-language breakdown of the most common reasons machinery claims are declined or reduced, and what you can do about each one.

Overloading: The Exclusion That Catches Everyone Off Guard

Overloading is one of the most consistently misunderstood exclusions in plant and machinery insurance. Most operators know they shouldn't exceed a machine's rated capacity. What they don't always know is how their policy treats it when someone does.

Many machinery policy wordings exclude claims arising from deliberate or reckless overloading, and here's the part that surprises people: some wordings apply this exclusion whether or not the owner knew it was happening. If a hired operator pushed a crane beyond its rated lift capacity and something failed, the claim may be declined even if you, the owner, were nowhere near the site.

The same logic often applies to incorrect loading, where the load is within capacity but distributed or secured in a way that creates unsafe stress on the machine. And some policies go further, excluding claims where load-measuring instruments or limiters were defective, switched off, or bypassed at the time of the incident.

What to do about it

Make sure your operators, employed or contracted, understand the machine's rated capacity and that exceeding it isn't just a safety issue, it's an insurance issue. Check whether your policy includes any protection for owners when an operator breaches a condition without the owner's knowledge. Some wordings do include this kind of protection; many don't. That distinction matters enormously when you're hiring out equipment.

If you're using dry hire or wet hire arrangements, this is especially worth reviewing with your broker.

Unlicensed or Unqualified Operators

This one seems obvious, but it still catches people out. If a machine requires a specific licence, certification, or qualification to operate, and the person behind the controls doesn't have it, most policies won't respond to a claim arising from that operation.

The issue isn't always deliberate. Sometimes it's a site supervisor jumping on a machine to move it a few metres. Sometimes it's a new employee whose paperwork hasn't been fully verified. Sometimes it's a contractor who assured you they were qualified and wasn't.

The result can be a declined claim. In New Zealand, section 11 of the Insurance Law Reform Act 1977 can help: an insurer generally can't decline a claim because of a breach like an unlicensed operator, overloading or a maintenance lapse if you can prove it didn't cause or contribute to the loss. The burden of proving that is on you, though, so it's far better not to have to rely on it.

Beyond formal licensing, some policies also exclude claims where the machine was operated in an unsafe manner, even by someone who holds the right licence. This is a broader and more subjective exclusion, which is exactly why it's worth understanding before you need to rely on it.

What to do about it

Keep records. Licence copies, operator certifications, induction records, these aren't just good practice, they're your evidence when a claim is questioned. If you're running a fleet of heavy machinery like dump trucks or tip trucks, or equipment like telehandlers that require specific operator competencies, a documented operator management process is worth having.

Using the Machine Outside Its Intended Purpose

Every machine is designed and rated for specific tasks. When it's used for something outside that scope, or in a way the manufacturer explicitly advises against, you're likely operating outside the terms of your policy as well.

This comes up more often than you'd think. A machine rated for a particular ground condition being used on unstable terrain. An attachment being used in a way the manufacturer's manual doesn't sanction. A machine designed for one industry being pressed into service in another.

Insurers assess claims based on what the machine was being used for at the time of the incident. If that use falls outside the policy's intended scope, the claim is at risk.

What to do about it

When you're insuring a machine, be specific about how it's used, not just what it is. A telehandler used on a construction site has different risk characteristics than the same machine used in an agricultural setting. Make sure your policy reflects your actual operations, not a generic description.

Failure to Maintain the Machine

Insurance covers sudden and accidental loss. It's not designed to cover the consequences of deferred maintenance or mechanical wear that was known about and ignored.

If an insurer can demonstrate that a machine was in poor condition at the time of the incident, that a fault was pre-existing, that scheduled servicing hadn't been done, or that a known issue wasn't addressed, they have grounds to reduce or decline the claim. This is separate from machinery breakdown insurance, which is a different type of cover designed for mechanical failure.

The challenge is that the line between sudden mechanical failure and gradual deterioration isn't always clear. Insurers will look at service records, maintenance logs, and the condition of the machine at the time of the loss. If those records are missing or incomplete, that ambiguity tends to work against the claimant.

What to do about it

Keep service records. Not just for safety compliance, for insurance purposes. A well-documented maintenance history is one of the strongest things you can have in your corner when a claim is being assessed. If you're managing a larger fleet, consider whether your maintenance tracking is actually capturing what you need it to capture.

Under-Declared Value

This is a quieter problem, but it's widespread. When a machine is insured for less than its actual replacement value, whether because the sum insured was set years ago and never updated, or because the owner underestimated the cost, the consequences at claim time can be significant.

Some policies include an averaging or co-insurance provision. In plain terms: if your machine is insured for 70% of its actual value, the insurer may only pay 70% of your claim, even for a partial loss. The owner effectively becomes their own insurer for the shortfall.

Machinery values have moved substantially in recent years. Replacement costs for plant and equipment have increased, and policies that haven't been reviewed to reflect this are quietly underinsured.

What to do about it

Review your sum insured figures annually, not just when you renew. If you're not sure what your machines would cost to replace today, get a current valuation. Agreed value machinery insurance is worth considering for high-value plant, because it removes the ambiguity about what you'll receive at claim time.

Undisclosed Hire Arrangements

This is the one that surprises plant owners most. If you hire out your machinery, even occasionally, and your policy doesn't know about it, you may have a problem.

Hire arrangements change the risk profile of a machine significantly. The insurer is now covering a machine being operated by people they know nothing about, in circumstances they haven't assessed. Many policies either exclude hire arrangements entirely or require specific disclosure and endorsement.

This applies to both dry hire and wet hire. Dry hire, where you supply the machine without an operator, is often treated as higher risk because you have no control over who's operating it or how. Wet hire, where you supply the machine with your own operator, is different, but still needs to be disclosed.

If you're hiring out equipment and your policy doesn't reflect that, a claim arising during a hire period is likely to be declined.

What to do about it

Be upfront with your broker about how your machines are used. If hire is part of your business model, even a small part, make sure your policy is structured to accommodate it. This isn't a difficult thing to arrange, but it has to be done before the claim, not after.

A Practical Checklist: Before Your Next Claim

Use this as a starting point for a policy review conversation with your broker:

• Operator records: Do you have current licence and certification copies for everyone who operates your machines?
• Maintenance logs: Are service records up to date and accessible?
• Sum insured: When was the last time you checked replacement values against current market costs?
• Hire arrangements: Does your policy reflect how your machines are actually used, including any hire?
• Intended use: Is the policy description of each machine accurate, including attachments and operating environments?
• Load management: Do your operators understand the machine's rated capacity and the policy implications of exceeding it?
• Breakdown vs. damage: Do you have separate machinery breakdown cover for mechanical failure, or are you assuming your plant policy covers it?

None of these are complicated. But they're easy to overlook when you're focused on running a business.

What a Broker Actually Does Here

A direct insurer can't advocate for you at claim time, they work for the insurer, not for you. That's not a criticism, it's just the structure. When a claim is being assessed and there's ambiguity about whether a condition was met, you want someone in your corner who's read the policy, knows the market, and can push back on behalf of the client.

At Gerrards, we work across machinery insurance for a wide range of plant and equipment. We review policies annually, not just at renewal, because the gap between what a policy says and what an owner thinks it says tends to widen quietly over time. We'd rather find that gap in a review than in a declined claim.

Every business is different. Your policy needs will depend on your specific circumstances, the machines you operate, and how they're used. This is general information only, for advice tailored to your situation, get in touch with our team.
