Car Insurance Excess: How Much is Too Much & Why in the UK?

When you buy car insurance, you’ll see a figure for ‘excess’. This is the amount you agree to pay towards any claim you make. Your insurer then covers the rest, up to your policy’s limit. It’s a crucial part of your policy, but many drivers don’t fully grasp how it works or how to set it correctly. This can lead to unexpected costs when you least expect them.

Understanding your excess is key to managing your car insurance costs and avoiding nasty surprises. It’s not just about the initial premium; it’s about what you’ll actually pay if something goes wrong. Let’s break down what you need to know.

Two Parts to Your Excess
Your total excess is made up of compulsory and voluntary amounts. Compulsory is set by the insurer, while voluntary is your choice.

Claiming vs. Paying
If a repair costs less than your total excess, it’s usually better to pay for it yourself and avoid making a claim.

Impact on No-Claims Discount
Making a claim can cost you several years of your no-claims discount, which is often more valuable than the repair cost.

Affordability is Key
Always set your voluntary excess based on what you can afford to pay if you need to make a claim.

Understanding Your Car Insurance Excess

Excess
The amount you pay towards a claim before your insurer pays the rest.

Car insurance excess has two parts. There’s the compulsory excess, which your insurer sets. This is based on factors like the car’s value, your age, and your driving history. Then there’s the voluntary excess, which you choose. You can decide to pay more upfront if you make a claim. This is often done to lower your annual premium.

Your total excess is the sum of these two amounts. For instance, if your compulsory excess is £250 and you choose a voluntary excess of £200, you’ll pay £450 towards any claim. This is a crucial point that many people miss. They focus on the premium reduction from a higher voluntary excess without fully considering the total amount they’d have to pay out of pocket.

If I were in this situation, I’d want to know the exact total excess figure before agreeing to anything. This ensures I’m not surprised by the combined amount later on.

Why Excess Amounts Vary Significantly

The amount of excess on your car insurance isn’t fixed across the board. It can differ greatly depending on several factors. Insurers use this to manage their risk. For younger or newer drivers, the compulsory excess is often much higher. This is because they are statistically more likely to make a claim. You might see compulsory excesses ranging from £300 to £500 or even more for drivers under 25. For some young drivers, the total excess, including their voluntary amount, could easily exceed £1,000.

This higher excess for young drivers is a direct reflection of the increased risk insurers perceive. It’s a way for them to balance the potential costs. On the other hand, drivers over 65 tend to have a better understanding of their policies. They also generally face lower compulsory excesses. Research shows that only 17% of drivers aged 18 to 24 fully understood compulsory excess, compared to 73% of those over 65.

This disparity highlights a real-world complication: the people who might need insurance the most and are often charged the most are also the least likely to understand the details of their excess. This can lead to them agreeing to terms they don’t fully grasp, potentially leaving them exposed financially.

Young Driver Excess
Compulsory excesses for young drivers can be £300 to £500 or higher, pushing the total excess well over £1,000 in some cases.

If you’re looking for ways to potentially lower your insurance costs, adjusting your voluntary excess is one route. A higher voluntary excess can indeed bring your premium down. However, it’s a trade-off. You’re essentially betting that you won’t need to make a claim. If you do, you’ll have to pay that larger amount yourself.

What I would do is calculate the total excess amount. Then, I’d check my savings. If I couldn’t comfortably afford that total sum, I’d lower my voluntary excess, even if it meant a slightly higher premium. Peace of mind is worth a lot.

Common Mistakes When Setting Your Excess

Choosing an Excess You Cannot Afford

One of the most frequent errors drivers make is setting a voluntary excess simply to reduce their car insurance premium. They might opt for a £500 voluntary excess to knock a significant amount off their annual cost. However, they may not realise that their compulsory excess is also high, perhaps £250. This means their total excess is £750. The problem arises when they need to make a claim. If they don’t have £750 readily available, the claim won’t proceed. This leaves them in a difficult position, potentially unable to get their car repaired.

Not Understanding the Impact on No-Claims Discount

Another common pitfall is underestimating the value of a no-claims discount. When you make a claim, you typically lose several years of your no-claims history. This loss can be far more costly in the long run than the repair itself. If the cost of the repair is less than the financial impact of losing, say, three years of your no-claims discount, it’s often better to pay for the repair yourself. This is a practical trade-off that many overlook in the moment of needing a repair.

In that case, I’d want to compare the repair cost against the estimated increase in my premium over the next few years due to losing my no-claims discount. If the discount’s value is higher, I’d pay for the repair out of pocket.

Assuming Excess Applies Only Once

A less obvious, but still common, misunderstanding is how excess applies. Many people think of it as a one-off payment per policy year. In reality, your excess is applied per claim. This means if you have two separate incidents that require a claim within the same policy year, you will have to pay your full excess amount twice. This can quickly become a very expensive situation if you’re not prepared for it.

This is where a dash cam can be useful. While it won’t change your excess, it can help prove fault in an accident, potentially avoiding a claim altogether. Something like the Garmin Dash Cam X310 could provide crucial evidence.

Ignoring the Total Excess Amount

Some drivers focus solely on the voluntary excess they select, forgetting to add it to their compulsory excess. This leads to an inaccurate picture of their total financial commitment. The excess amount should always be based on what you can afford to pay at short notice. It should not be dictated solely by what looks cheapest on a comparison site quote. A policy that looks good on paper can become a financial burden if you can’t meet the excess when you need to claim.

Here’s a quick comparison of how different excess levels might affect your out-of-pocket costs:

£400£600£1,000Major accident £3,000. You pay £1,000, insurer pays £2,000.

Setting Your Excess Wisely

Assess Your Financial Situation

The most important step in setting your excess is to be brutally honest about your finances. How much money could you realistically access within 24 hours if you needed to pay for a car repair? Think about your savings, emergency funds, or any readily available credit. If you only have a small emergency fund, a high voluntary excess is a risky choice. It’s better to have a slightly higher premium and a lower total excess that you know you can afford.

Consider the Value of Your No-Claims Discount

Try to estimate how much your no-claims discount is worth over a few years. Many comparison sites will show you the potential impact of making a claim on your future premiums. If the cost of losing your no-claims discount for two or three years is significantly more than the cost of the repair, it’s usually best to pay for the repair yourself. This is a real-world complication where the immediate cost of a repair can be less important than the long-term financial implications of claiming.

Factor in Vehicle Type and Risk

Certain vehicles attract higher excesses. High-performance cars, expensive cars, or cars that are frequently stolen are often subject to higher compulsory excesses. If you drive a car that falls into one of these categories, you might find that your compulsory excess is already quite high. This means you have less flexibility when choosing your voluntary excess, as you need to ensure the total amount remains affordable.

If I were driving a high-value car, I’d want to ensure I had a robust security system in place. A physical deterrent like a Stoplock Steering Wheel Lock could help reduce the perceived risk, potentially influencing my insurance terms.

Review Your Policy Annually

Your circumstances can change, and so can your insurance needs. It’s essential to review your car insurance policy every year. Check your excess levels and ensure they still align with your financial situation and risk appetite. Don’t just auto-renew without looking at the details. You might find that you can now afford a higher voluntary excess, or conversely, that your financial situation has changed, and you need to reduce it.

Frequently Asked Questions About Car Insurance Excess

Insurers usually offer a range of voluntary excess options. The maximum you can choose might be limited by the insurer.
What happens if I can’t afford my excess?
