The average UK car insurance premium reached £924 in 2025. This figure can feel like a lot, especially when you’re trying to manage your household budget. Many drivers look for ways to trim these costs without compromising on essential cover. One common strategy is adjusting your excess, the amount you pay towards a claim before your insurer steps in.
Understanding how your excess works is key to potentially lowering your premiums. It’s a balance between paying less upfront and being prepared for a larger contribution if you need to make a claim. This article will guide you through the options for adjusting your car insurance excess and what factors to consider.
Understanding Your Car Insurance Excess
Your car insurance excess is split into two parts: the compulsory excess and the voluntary excess. The compulsory excess is set by the insurer and is usually based on factors like the car’s value, age, and your driving history. You cannot change this amount. The voluntary excess, however, is the extra amount you agree to pay on top of the compulsory excess. This is where you have some control.
By increasing your voluntary excess, you are essentially telling the insurer that you are willing to take on more financial responsibility if you need to make a claim. In return for this increased commitment, insurers often offer a lower premium. It’s a trade-off that can work well for many drivers, but it’s crucial to understand the implications.
If I were in this situation, I’d first check my savings to ensure I could cover the higher excess amount without causing financial hardship. This practical step ensures the potential premium saving doesn’t lead to a bigger problem later.
The Financial Benefits of a Higher Voluntary Excess
The primary reason drivers consider increasing their voluntary excess is the potential for immediate savings on their car insurance premiums. Insurers see a higher voluntary excess as a sign of a lower-risk customer. This is because you are demonstrating a greater personal stake in preventing claims.
For example, increasing your voluntary excess from £100 to £500 could lead to a reduction in your premium of between 10% and 15%. If your annual premium was £800, this could mean a saving of £80 to £120 per year. Pushing the voluntary excess even higher, to £750, might offer savings ranging from 12% to 18%. For that same £800 premium, this could translate to an annual saving of £96 to £144.
These figures highlight the direct financial incentive. However, it’s essential to remember that these are potential savings. The exact reduction will vary significantly between insurance providers and depend on your individual circumstances, such as your age, driving record, and the type of car you drive.
It’s also worth noting that the difference between the cheapest and most expensive quotes for the same driver can exceed £500. This suggests that simply shopping around can yield substantial savings, independent of adjusting your excess.
The decision to increase your voluntary excess isn’t just about the premium reduction; it’s about your personal financial resilience. If you were to have an accident, you would need to pay your combined compulsory and voluntary excess before the insurer covers the rest. Therefore, it’s vital to choose an amount you can comfortably afford without causing undue financial stress.
For instance, if your compulsory excess is £200 and you set your voluntary excess at £500, your total excess for a claim would be £700. Can you readily access £700 if needed? If not, a lower voluntary excess, even if it means a slightly higher premium, might be a more prudent choice.
Common Pitfalls When Adjusting Your Car Insurance Excess
Underestimating the Total Excess Amount
One of the most common mistakes is focusing solely on the voluntary excess figure without fully understanding the total amount you might have to pay. Your policy documents will clearly state both the compulsory and voluntary excess. It’s the sum of these two that represents your total contribution towards a claim. Failing to calculate this total can lead to a nasty surprise when you need to make a claim.
If I were reviewing my policy, I’d make sure to highlight the total excess figure on a piece of paper and keep it somewhere visible. This helps to keep the actual financial commitment top of mind.
Ignoring the Impact on Other Policy Benefits
Sometimes, insurers might link certain benefits to the excess level. For example, some policies might offer a courtesy car only if the repair cost exceeds a certain amount, which could indirectly be affected by your excess. While not directly tied to the excess amount itself, it’s a detail worth checking in your policy wording. Always read the fine print to ensure you aren’t inadvertently losing out on other valuable aspects of your cover.
Not Shopping Around for the Best Deal
Many drivers stick with their existing insurer year after year, assuming their renewal quote is competitive. However, the insurance market is constantly changing. What was the best deal last year might not be the best deal today. Drivers who compare and switch can save an average of £120 to £250 annually. It’s always worth getting quotes from multiple providers when your renewal date approaches.

| Voluntary Excess | Potential Premium Saving | Consideration |
|---|---|---|
| £100 (Standard) | N/A | Lower out-of-pocket cost per claim. |
| £250 | Moderate | A balanced approach for many drivers. |
| £500 | 10–15% | Requires higher affordability for claims. |
| £750 | 12–18% | Significant savings, but demands substantial claim affordability. |
Making Changes Mid-Term Unnecessarily
While you can often adjust your excess mid-term, it might not always be the most cost-effective strategy. Insurers may charge an administration fee for making changes to your policy. It’s usually more beneficial to review and adjust your excess when you are renewing your policy. This avoids potential fees and ensures you are getting the best overall deal.
Strategies for Reducing Your Car Insurance Costs
Beyond adjusting your excess, several other practical steps can help lower your car insurance premiums. These strategies often involve demonstrating that you are a lower-risk driver or making your vehicle less attractive to thieves.
Timing Your Renewal
One of the most effective strategies is to shop around at the right time. Research suggests that the cheapest car insurance prices are typically found around 21 days before your renewal date. Leaving it until the last minute can often result in paying more. Insurers tend to offer better deals to customers who plan ahead.
Improving Your Car’s Security
Making your car more secure can lead to lower premiums. Installing an approved alarm system or immobiliser, or even using a steering wheel lock like the Stoplock Steering Wheel Lock, can deter potential thieves. Insurers recognise these security measures as risk-reducing factors. If you have a valuable car, investing in a robust security device could pay for itself through insurance savings.
Considering Telematics (Black Box) Insurance
Telematics devices, often referred to as ‘black boxes’, are installed in your car to monitor your driving habits. Insurers use this data to assess your driving style. If you are a safe and responsible driver, this can lead to significant discounts. This technology can be particularly beneficial for younger or newly qualified drivers who often face higher premiums. You can learn more about how black box technology can save you money.
Maintaining a Good Driving Record
Your driving record is one of the most significant factors influencing your insurance premiums. Avoiding accidents, speeding tickets, and other driving convictions is crucial. Many insurers offer discounts for drivers with a long history of no claims. Protecting your no-claims bonus is therefore a key strategy for long-term savings.
Reviewing Your Annual Mileage
The number of miles you drive each year directly impacts your risk profile. If you drive fewer miles, you are less likely to be involved in an accident. Accurately estimating your annual mileage and informing your insurer can lead to lower premiums. If your circumstances change and you start driving less, be sure to update your insurer.
If I were looking to reduce my premium, I’d start by checking my estimated annual mileage. If it’s lower than I last declared, I’d contact my insurer immediately. This is a straightforward way to potentially lower costs without changing my excess or security measures.
Considering Dash Cams
While not always directly linked to premium reductions, dash cams can be invaluable in the event of a claim. A dash cam can provide objective evidence of an accident, which can help to prove your innocence and potentially protect your no-claims bonus. Some insurers may offer small discounts for vehicles fitted with approved dash cams, such as the Garmin Dash Cam X310.
