When a car insurance quote asks you to choose a voluntary excess, it can look like an easy way to trim the price. Increase the excess, watch the premium fall, and the cheaper quote seems to win. The catch is that you are agreeing to take on more of the cost if you later make a claim.
That makes voluntary excess car insurance less about choosing the highest number available and more about finding a level you could comfortably pay at short notice. The best choice is usually the one that gives you a worthwhile premium saving without turning a future claim into a financial problem.
What voluntary excess actually means
An insurance excess is the part of an eligible claim that you are responsible for. With UK car insurance, there are commonly two figures to watch: compulsory excess and voluntary excess.
The compulsory excess is set by the insurer. The voluntary excess amount is the extra sum you agree to contribute yourself. For many claims, the two are added together to create your total policy excess.
For example, if your compulsory excess is £200 and you choose a £250 voluntary excess, your total excess would usually be £450 for a claim to which both amounts apply. If covered repairs cost £2,000, you would effectively bear the first £450 and the insurer would cover the remaining eligible amount, subject to the policy terms.
Does a higher excess always mean a lower premium?
A higher voluntary excess can reduce the premium because you are taking on more of the potential claim cost. However, a higher excess does not guarantee a lower premium, and the saving may become very small once you move beyond a certain point.
Insurers price risk using many factors, including the driver, vehicle, address, claims history, mileage and cover selected. Voluntary excess is only one part of that calculation. The useful comparison is how much extra claim risk you accept for each pound saved on the annual premium.
A practical way to choose your voluntary excess amount
Run the same quote several times with only the voluntary excess changed. Keep everything else identical, then compare the premium and total excess side by side.
Imagine your compulsory excess is £200. A £100 voluntary excess produces a £760 annual premium, while a £500 voluntary excess reduces it to £700. You save £60 a year, but you would take on an extra £400 of cost if you made a claim where both excesses applied.
If you have a solid emergency fund and are comfortable accepting that risk, the saving may suit you. But if finding £700 at short notice would be difficult, the cheaper premium could be false economy.
A practical rule is to choose the highest total excess you could pay without borrowing, missing essential bills or delaying necessary repairs. Then decide whether the premium saving is large enough to justify taking on that extra risk.
Check the total excess, not just the quote screen
The cheapest annual premium is not always the lowest-cost policy for you. Insurance claim costs matter because the excess becomes relevant when you are already dealing with an accident, theft or damage.
Check whether different parts of the policy carry different excesses. Windscreen claims, for example, may have a separate excess from accidental damage. Some policies may also apply different compulsory amounts depending on the driver or type of claim. Your policy schedule and wording should show the figures that apply.

What if the repair cost is close to your excess?
A high total excess can make smaller claims uneconomic. If a covered repair costs £500 and your applicable excess is £450, the insurer’s contribution may be only £50. You might decide that making a claim is not worthwhile.
Even so, follow the policy’s rules about reporting accidents or incidents. Some insurers require notification even when you do not intend to claim. Reporting an incident and making a claim are not always the same thing.
What happens after a non-fault accident?
Being blameless does not necessarily mean the excess disappears immediately. Depending on how the claim is handled, your excess may initially be deducted or collected and later recovered from the at-fault driver’s insurer. Recovery is not handled identically in every case, so ask your insurer what it will do and whether you need to pursue the amount yourself.

When a lower voluntary excess may make more sense
A lower figure can be sensible when your compulsory excess is already high, your emergency savings are limited, or the premium reduction for increasing the excess is tiny. If the premium difference is modest, paying slightly more for the policy may be reasonable in exchange for a smaller financial shock after a claim.
When a higher voluntary excess can work
A higher excess may suit someone who has enough cash set aside and receives a meaningful premium reduction for accepting more risk. The excess should be money you could genuinely access, not an amount that only looks manageable while you are completing the quote.
Recheck the numbers at every renewal. Your insurer’s pricing, compulsory excess and premium can change, so last year’s best voluntary excess amount may not be the best choice this year.
FAQ
What is the difference between compulsory and voluntary excess?
Compulsory excess is set by the insurer, while voluntary excess is an additional amount you choose. For many claims, both are added together, so check the total rather than looking at either figure alone.
Can I choose zero voluntary excess?
Some policies or quote systems allow a £0 voluntary excess, while others offer a limited set of choices. Even with no voluntary excess, you may still have to pay the compulsory excess and any separate excess that applies to a particular type of claim.
Will increasing my voluntary excess always make my insurance cheaper?
No. It often reduces the premium, but the effect varies by insurer and risk profile. Test several excess levels on otherwise identical quotes and compare the saving with the extra amount you would have to contribute to a claim.
Can I change my voluntary excess after buying the policy?
That depends on the insurer and policy. The excess is normally selected when you buy or renew cover. If you want to change it mid-policy, ask the insurer whether an amendment is allowed and whether it changes the premium or attracts a fee.
Choosing an excess you can live with
The right voluntary excess is not simply the highest number that produces the lowest quote. It is the amount that balances a sensible premium with a total policy excess you could afford if something went wrong. Compare several settings, check the compulsory excess and any claim-specific excesses, and judge the saving against the extra cash you would need at claim time. A modest premium reduction is rarely worth creating a bill you would struggle to pay.
