A £500 repair bill after a parking scrape can feel very different depending on the excess on your policy. So, what is voluntary excess? It is the amount you agree to contribute towards a claim, on top of any compulsory excess set by your insurer. Choosing a higher figure can reduce the price of your car, van or motorbike insurance, but only if you could comfortably pay it when you need to claim.

For many drivers, voluntary excess is one of the quickest ways to adjust a quote. It should never be treated as a free discount, though. It changes how much of the financial risk you keep yourself.

What is voluntary excess and how does it work?

Your policy excess is the first part of an insured loss that you pay. It is normally made up of two parts: compulsory excess and voluntary excess. The insurer sets the compulsory excess based on factors such as your age, vehicle, postcode, claims history and the type of cover you choose. You select the voluntary excess when getting a quote or amending your policy.

The two figures are added together. If your compulsory excess is £250 and you choose a voluntary excess of £300, your total excess is £550.

Imagine your car is damaged in an accident and the approved repair costs £2,000. Provided the claim is covered, you pay £550 and the insurer pays the remaining £1,450. If the repair costs only £400, you would usually pay for it yourself because it is below your total excess.

This is why the lowest annual premium is not always the best value. A policy that saves £80 a year but adds £300 to your excess may not suit you if an unexpected bill would be hard to manage.

Why does a higher voluntary excess lower your premium?

Insurance is designed to help with larger, unexpected costs. By accepting a higher voluntary excess, you are telling the insurer you will cover more of the cost of a claim yourself. That reduces the insurer’s potential payout, which can bring down your premium.

The saving varies widely. On some quotes, increasing voluntary excess makes a noticeable difference. On others, it barely changes the price. This depends on the vehicle, driver profile, location, cover level and claims risk the insurer sees.

There is also a tipping point. Selecting a very high voluntary excess may deliver little extra saving while leaving you exposed to a significant bill. Rather than automatically choosing the highest option, compare several excess levels and look at the full policy price each time.

Compulsory excess versus voluntary excess

The difference matters because you control only one part of the total.

Compulsory excess is set by the insurer and cannot normally be removed. It may include additional excesses for younger or inexperienced drivers. For example, a policy could apply a standard compulsory excess plus an extra young-driver excess where the driver is under a specified age.

Voluntary excess is the amount you choose. You may be offered options from £0 to several hundred pounds, depending on the insurer and vehicle. A lower voluntary excess generally means a higher premium, while a higher one can reduce it.

Always check the policy details for the total excess, not just the voluntary figure shown on the quote screen. This is particularly useful for younger drivers, high-value cars, performance motorbikes and vans used for work, where compulsory excesses can be higher.

When do you pay voluntary excess?

You normally pay the total applicable excess whenever you make a covered claim, but the exact process depends on the insurer and the type of claim. A repairer may ask you to pay it when collecting your vehicle, or the insurer may deduct it from a settlement payment.

If your vehicle is written off, the insurer will usually value it and deduct the excess from the settlement. For example, if the agreed vehicle value is £6,000 and your total excess is £500, you could receive £5,500, subject to the policy terms.

Windscreen claims can work differently. Many policies have a separate, lower windscreen excess, and some have different amounts for repair and replacement. Breakdown cover, legal expenses cover and personal accident benefits can also have their own terms. Check the documents rather than assuming the main excess applies to every part of the policy.

What if an accident was not your fault?

You may still have to pay your excess initially, even if another road user caused the accident. If your insurer successfully recovers its costs from the at-fault party or their insurer, it may recover and refund your excess too.

That is not guaranteed, and it can take time. The other driver may be uninsured, liability may be disputed, or there may not be enough evidence to establish fault. Report the incident promptly, keep photos and details of witnesses, and give your insurer all the information it asks for.

How to choose the right voluntary excess

The right figure is personal. Start with a simple question: could you pay the total excess tomorrow without borrowing or missing essential bills? If the answer is no, reduce the voluntary excess, even if the premium rises.

Next, consider the value and use of your vehicle. A small increase may make sense where you have an emergency fund and mainly want protection against major losses. It may be less suitable if you rely on your car or van every day and would struggle to fund repairs after a minor collision.

For a van driver, downtime can create costs beyond the repair itself. A high excess might look attractive at renewal, but a claim could affect cash flow at exactly the wrong moment. Motorbike riders should take the same care, especially if parts and repairs for their model are expensive.

It also helps to look at your driving environment. Regular city driving, tight residential parking and high annual mileage can increase the chance of small damage claims. No one can predict an accident, but your usual journeys should inform how much risk you are comfortable retaining.

Compare the whole quote, not just the headline price

A good comparison looks beyond the annual premium. Check the compulsory excess, voluntary excess and total payable amount, then consider the cover included. Courtesy car availability, windscreen cover, protected no claims discount, driving other cars cover and restrictions on named drivers can all vary between policies.

Pay attention to any separate excesses too. Some policies apply a higher excess for theft, fire, young drivers or certain vehicle modifications. If you insure a van, make sure the use class reflects how you genuinely use it, whether that is social use, commuting or carriage of your own goods. Incorrect details can create problems when you need to claim.

The aim is not to find the policy with the lowest number on the first page. It is to find cover that gives you a competitive price and a realistic financial commitment if something goes wrong. UKcompare lets you compare car, van and motorbike insurance quotes, helping you weigh up those details before you choose.

Can you change voluntary excess later?

In many cases, yes. You may be able to change your voluntary excess during the policy term or at renewal, although an insurer could charge an administration fee or adjust your premium. The new amount should only apply from the date the change is accepted, not to an incident that has already happened.

Renewal is a sensible time to review it. Your circumstances may have changed: perhaps you have built a stronger emergency fund, changed vehicle, moved home or added a younger driver. Do not simply renew on the same settings because they worked last year.

A voluntary excess should give you control, not create a nasty surprise after an accident. Choose a figure you can genuinely afford, compare the resulting premiums carefully, and keep the total excess written down where you can find it. Who Compares Wins!
