Introduction
Car insurance excess is one of the most important parts of a car insurance policy, yet many UK drivers do not fully understand how it works until they need to make a claim.
The excess is the amount a policyholder may need to contribute towards the cost of a claim before the insurer pays the remaining amount.
Most car insurance policies include both compulsory excess and voluntary excess. The level of excess selected can affect both insurance premiums and potential claim costs.
Choosing the right excess requires balancing affordable premiums against the amount you could realistically pay if an accident or insured event occurs.
Understanding how excess works can help drivers avoid unexpected costs and make more informed insurance decisions.
This guide explains car insurance excess in the UK, the difference between compulsory and voluntary excess, how excess affects premiums and what drivers should know before making a claim.
What Is Car Insurance Excess?
Car insurance excess is the amount a policyholder usually agrees to contribute towards the cost of an insurance claim. If a claim is accepted, the excess is generally deducted from the settlement amount or paid as part of the claim process.
Excess is a common feature of most UK car insurance policies and helps insurers share some of the financial risk with policyholders.
Why Insurance Excess Exists
Insurance excess is designed to discourage very small claims and encourage responsible driving. It also helps insurers manage claim costs and keep insurance products commercially viable.
How Excess Works
If a driver makes a successful claim, the excess amount is normally applied before the insurer pays the remaining claim value. The exact process depends on the insurer and the type of claim involved.
Understanding excess is important because it directly affects how much a driver may need to contribute when making a claim.

Compulsory vs Voluntary Excess
Most car insurance policies include two types of excess: compulsory excess and voluntary excess. Understanding the difference can help drivers choose suitable levels of cover.
Compulsory Excess
Compulsory excess is set by the insurer and cannot normally be removed. The amount may vary depending on factors such as age, driving experience, vehicle type and claims history.
Voluntary Excess
Voluntary excess is an additional amount chosen by the policyholder. Drivers may increase voluntary excess in exchange for lower insurance premiums, although this increases the amount they may need to pay when making a claim.
Total Excess
The total excess payable is usually the combined amount of compulsory and voluntary excess.
Before purchasing insurance, drivers should ensure any excess selected remains affordable if a claim becomes necessary.
New drivers may wish to compare different policy options carefully before selecting excess levels. Learn more in our Cheap Car Insurance for Young Drivers UK guide.

How Excess Affects Insurance Premiums
The level of excess selected can influence insurance premiums. In many cases, choosing a higher voluntary excess may reduce the cost of insurance because the policyholder is accepting a larger share of potential claim costs.
Higher Excess
Higher excess levels may reduce premiums, but they also increase the amount a driver may need to contribute if a claim is made.
Lower Excess
Lower excess levels may result in higher premiums because the insurer is taking on a greater proportion of the potential claim cost.
Finding the Right Balance
Drivers should balance affordability today against potential claim costs in the future. Selecting an excess amount that is difficult to pay after an accident may create financial challenges.
Insurance decisions should always consider both premium costs and potential excess obligations.
Drivers comparing insurance costs should also understand how no claims discounts may influence premiums. See our No Claims Bonus Explained UK guide for more information.

When Do You Pay Excess?
Insurance excess is generally applied when a claim is made and accepted under the policy. The exact timing and method vary depending on the insurer and repair arrangements.
Accident Claims
If a driver makes a claim following an accident, excess may apply before repairs are completed or before settlement payments are issued.
Fault and Non-Fault Claims
Excess may initially apply to both fault and non-fault claims. In some situations, excess may later be recovered if another party is responsible and costs are successfully recovered.
Windscreen and Special Claims
Some policies apply different excess amounts to specific claim types such as windscreen repairs or replacements.
Policyholders should review their policy documents carefully to understand when excess applies and how claims are handled.

Common Myths About Insurance Excess
Myth 1: Excess Is an Extra Insurance Fee
Insurance excess is not an additional fee charged by insurers. It is the contribution a policyholder may need to make towards a claim.
Myth 2: Higher Excess Is Always Better
While higher excess may reduce premiums, it can also create larger out-of-pocket costs following an accident.
Myth 3: Excess Only Applies to Fault Claims
Depending on policy terms, excess may initially apply to both fault and non-fault claims.
Myth 4: All Policies Have the Same Excess
Different insurers use different excess structures. The amounts can vary significantly between policies and drivers.
Myth 5: Excess Never Changes
Insurers may adjust compulsory excess levels based on driver risk, vehicle type or policy changes.
Understanding how excess works can help drivers make informed insurance decisions and avoid unexpected costs when making a claim.
Understanding named drivers can also be useful. See our Named Driver Insurance UK guide.
