A deductible is one of the most important parts of a car insurance policy, and it is also one of the least understood. It is the amount the driver agrees to pay toward a claim before the insurer pays the rest. Every claim that is covered by the policy is affected by it, so understanding it before buying cover matters.
This guide explains what a deductible is, how it works in practice, why insurers offer a choice of deductible levels, and how that choice changes the premium. It also explains the difference between a compulsory deductible and a voluntary deductible.
What a deductible is
A deductible, sometimes called an excess in some markets, is a fixed amount that the policyholder pays when a claim is made. If the cost of a repair is higher than the deductible, the insurer pays the amount above the deductible. If the cost of the repair is lower than the deductible, the insurer usually pays nothing, and the driver covers the full repair cost.
For example, if a policy has a deductible of a set amount and a repair costs more than that amount, the driver pays the deductible and the insurer pays the rest. If the repair costs less than the deductible, the driver pays the whole repair cost and there is no point in claiming. That is why small scratches and minor damage are often paid for without a claim.
The deductible applies to each claim, not to the whole policy year. If a driver makes two separate claims in one year, the deductible usually applies to each one. That detail matters when a driver is weighing up whether to claim for a small amount of damage.
Compulsory and voluntary deductibles
Many policies have two parts to the deductible. The compulsory deductible is set by the insurer and cannot be changed by the driver. It often depends on the driver age, the car and the type of cover. Younger drivers and drivers of more powerful cars often have a higher compulsory deductible.
The voluntary deductible is an extra amount the driver chooses to add on top of the compulsory amount. A driver can choose a low voluntary deductible or a high one, or none at all. The total deductible is the compulsory amount plus the voluntary amount, and that total is the amount the driver pays toward a claim.
Some policies also have different deductibles for different types of claim. A claim for windscreen damage may have a lower deductible than a claim for accident damage, for example. The policy wording sets out each deductible, so it is worth reading the full schedule rather than assuming one figure applies to everything.
How a deductible changes the premium
A higher deductible usually means a lower premium. That is because the driver is taking on more of the risk. If the driver agrees to pay more toward any claim, the insurer expects to pay less, so it charges less for the policy. A lower deductible usually means a higher premium, because the insurer takes on more of the risk.
This trade off is at the heart of choosing a deductible. A high deductible can save money on the premium each year, but it can also mean a large bill if a claim happens. A low deductible costs more each year, but it means a smaller bill at claim time. Neither choice is right for everyone.
The saving from a higher deductible is not always large. In some cases, raising the deductible by a large amount only lowers the premium by a small amount. In that case, the extra risk may not be worth the small saving. Comparing quotes with different deductible levels shows how much is actually saved.
Choosing a deductible you can afford
The most important rule is simple: never choose a deductible that cannot be paid. A deductible is not a theoretical figure. It is money that must be found quickly after an incident, often at a stressful time. If a driver could not pay the deductible without borrowing or going without the car, the deductible is too high.
A practical way to choose is to think about savings. If a driver has savings that could cover a higher deductible without difficulty, a higher deductible may be a reasonable way to lower the premium. If savings are tight, a lower deductible gives more protection, even though the premium is higher.
It also helps to think about the car value. A very high deductible on a low value car may leave little benefit in claiming at all, because the repair cost may be close to the deductible. In that case, a lower deductible or a different level of cover may make more sense.
What happens at claim time
When a claim is made, the insurer usually explains how the deductible will be handled. In many cases, the driver pays the deductible to the repairer, and the insurer pays the rest directly to the repairer. In other cases, the insurer pays the full repair cost and then collects the deductible from the driver.
If the driver was not at fault and the other driver insurer pays for the damage, the deductible may be recovered. That process can take time, and it is not always successful. If the other driver cannot be traced or has no insurance, the deductible may not be recovered.
For a claim that is not the driver fault, some policies offer a way to protect the no claims record, but the deductible may still apply at first. The policy wording explains how each type of claim is treated, and the insurer can confirm the position when a claim is reported.
When claiming may not be worth it
Because the deductible must be paid on every claim, small claims are often not worth making. If the repair cost is only a little more than the deductible, the insurer pays only a small amount, but the claim is still recorded and it may affect the next premium and the no claims record.
Before claiming for minor damage, a driver can get a repair quote and compare it with the deductible. If the repair cost is close to or below the deductible, paying for the repair directly may be the simpler choice. If the damage is larger, a claim makes more sense.
That decision should also take safety into account. Damage that affects the car safety, such as a cracked windscreen in the driver view or damaged lights, should be dealt with promptly, whether through a claim or a direct repair. Cost should not come before safety.
Common misunderstandings about deductibles
One common misunderstanding is that the deductible is paid once a year. In fact, it is paid on each claim. Another is that the deductible is returned after a claim. It is not returned, except in cases where the cost is recovered from another party.
Another misunderstanding is that a higher deductible always saves a lot of money. As noted above, the saving can be small, and it should be weighed against the extra amount that would need to be paid at claim time. A quote comparison with different deductible levels gives the real figures for that driver and that car.
Finally, some drivers assume the deductible is the same for every type of claim. It often is not. Windscreen claims, theft claims and accident claims can each have their own deductible. Reading the policy schedule avoids surprises.
This guide explains how cover generally works. It is not personal financial advice. Check your own policy wording before you decide.
What is a car insurance deductible?
A deductible is the amount the driver pays toward a claim before the insurer pays the rest. If the repair cost is higher than the deductible, the insurer pays the amount above it. If the repair cost is lower, the driver usually pays the full cost.
Does a higher deductible lower my premium?
In general, a higher deductible means a lower premium, because the driver takes on more of the risk. A lower deductible means a higher premium. The saving is not always large, so it is worth comparing quotes with different deductible levels.
What is the difference between compulsory and voluntary deductible?
A compulsory deductible is set by the insurer and cannot be changed. A voluntary deductible is an extra amount the driver chooses to add. The total deductible is the compulsory amount plus the voluntary amount.
Do I pay the deductible on every claim?
Yes, the deductible usually applies to each separate claim, not once a year. If a driver makes two claims in one year, the deductible usually applies to both. The policy wording sets out the exact terms.
