The excess is the amount you pay towards a claim before your insurer covers the rest. It appears on every motor and home insurance policy in the UK, but many policyholders misunderstand when it applies, how compulsory and voluntary excesses stack, and whether raising the excess is worth the premium saving. This guide explains how excess amounts work on UK car and home insurance, walks you through the decision on voluntary excess, and highlights the common mistakes that leave people underprepared at claim time.

What You Will Learn

By the end of this guide you will understand what an excess is and why insurers apply it, the difference between compulsory and voluntary excess, how excess works on motor insurance (including young driver, inexperienced driver, and endorsement loadings), how excess works on buildings and contents cover, when you actually pay the excess, how to choose a voluntary excess level that balances premium savings against affordable out-of-pocket costs at claim time, and the practical steps to check your current excess and adjust it at renewal.

Step 1: What Is an Excess?

An excess is the first portion of any claim cost that you, the policyholder, agree to pay yourself. The insurer covers the rest, up to the sum insured or any claim limit stated in your policy wording.

Every motor and home insurance policy in the UK carries an excess. The purpose is twofold: it discourages very small, uneconomical claims (administrative costs for a tiny claim can exceed the payout itself) and it aligns incentives (when you bear part of the cost, you take reasonable care to prevent claims).

Excess is typically a fixed cash amount per claim. For example, if your motor policy states a £300 excess and your bodywork repair costs £1,200, you pay £300 and the insurer pays £900. If the repair costs £200, you pay the entire cost yourself because it falls below the excess, so you would not submit a claim.

According to the Association of British Insurers, the excess structure has been a standard feature of UK insurance policies for decades and plays an important role in controlling claims costs (ABI, 2026).

Step 2: Types of Excess (Compulsory and Voluntary)

UK motor and home policies distinguish between compulsory excess (set by the insurer and non-negotiable) and voluntary excess (a top-up amount you choose at quote stage or renewal).

Compulsory Excess

The compulsory excess is the minimum amount the insurer requires you to pay per claim. The insurer sets this based on underwriting factors such as your postcode, the vehicle or property type, your age and experience (for motor cover), and your claims history.

For motor insurance, younger and less experienced drivers face higher compulsory excesses because the claims frequency and average cost in that demographic are higher. If you are under 25, for example, the insurer may apply an additional young driver excess (often £200 to £500) on top of the standard compulsory excess. Similarly, if you hold a provisional licence or have passed your test within the past year, an inexperienced driver excess may apply.

For home insurance, the compulsory excess on buildings and contents is typically lower (£100 to £250 is common) but may rise if the property is in a high-risk area (for flood, subsidence, or theft), if you have made recent claims, or if the property is non-standard construction.

You cannot negotiate the compulsory excess on an individual policy. If you find it too high, your only option is to shop around; some insurers apply lower compulsory excesses to the same risk.

Voluntary Excess

The voluntary excess is an optional top-up. At quote stage you select an amount (often £0, £100, £250, £500, or higher), and the insurer reduces your premium in return.

The total excess you pay at claim time is compulsory excess plus voluntary excess. For example, if your motor policy has a £200 compulsory excess and you chose a £300 voluntary excess, you pay £500 per claim.

Raising your voluntary excess lowers your premium because the insurer knows you will absorb more of any claim cost, reducing its payout and the likelihood you will claim for minor damage. The premium saving is typically non-linear: the first £100 or £250 of voluntary excess often delivers a noticeable discount, while increments beyond £500 produce diminishing returns.

Step 3: How Excess Works on Motor Insurance

Motor insurance excess can be complex because multiple excess amounts may apply to the same policy, and they stack.

Standard Policy Excess

A typical comprehensive motor policy might state a compulsory excess of £200 and allow you to add a voluntary excess of £0 to £1,000 in steps. If you add £250 voluntary excess, your total standard excess is £450.

Young and Inexperienced Driver Excess

If the main or named driver is under 25, the insurer usually applies a young driver excess (commonly £200 to £500) in addition to the standard policy excess. This is non-negotiable and stated in your policy schedule.

If the driver is over 25 but passed their test less than 12 or 24 months ago (the threshold varies by insurer), an inexperienced driver excess may apply instead, often at a similar level.

Both excesses stack. For example:

  • Standard compulsory excess: £200
  • Young driver excess: £350
  • Voluntary excess: £100
  • Total excess at claim time: £650

Always check your policy schedule (the document that lists your cover details and excess amounts) to see which excesses apply to you.

Endorsement and Conviction Excess

If you have motoring convictions (speeding points, drink-driving ban, or other endorsements on your licence), the insurer may add a conviction excess, typically £100 to £250. This, too, stacks with the other excesses.

Windscreen Excess

Most comprehensive policies include windscreen cover as standard, with a separate, lower excess for windscreen repair (often £0 to £75) and a higher excess for full windscreen replacement (often £75 to £150). This excess is independent of your main policy excess and does not affect it. Making a windscreen claim usually does not count against your no-claims bonus (NCB), provided you use the insurer’s approved repairer.

When You Pay the Motor Excess

You pay the excess at the point the insurer settles your claim. If the insurer arranges the repair through its approved network, you typically pay the excess directly to the repairer when you collect the vehicle. If you arrange your own repair or the insurer writes off the vehicle, the insurer deducts the excess from the settlement cheque.

If the accident was the other party’s fault and the insurer recovers the full claim cost from the third party’s insurer, your excess is usually refunded to you once recovery is complete. This can take several months.

Step 4: How Excess Works on Home Insurance (Buildings and Contents)

Home insurance distinguishes between buildings cover (the structure and permanent fixtures) and contents cover (possessions inside the property). Each may carry its own excess, or the policy may apply a single excess across both.

Buildings Insurance Excess

A typical buildings policy has a compulsory excess of £100 to £250. You can add a voluntary excess (commonly up to £500 or £1,000) to reduce the premium.

Certain perils may carry a higher or additional excess. For example:

  • Subsidence, heave, and landslip: Insurers often apply a separate subsidence excess (£1,000 or more) because these claims are expensive and take years to settle. The standard excess still applies to all other perils (fire, storm, flood, escape of water).
  • Flood: If your property is in a Flood Re scheme area or a high-risk postcode, the insurer may apply a flood-specific excess on top of the standard excess.

Contents Insurance Excess

Contents policies typically have a compulsory excess of £50 to £100, again with the option to add a voluntary excess.

If you make a claim for theft, fire, or accidental damage (if covered), you pay one excess per claim event, regardless of how many items were damaged or stolen in that single incident.

When You Pay the Home Excess

For buildings claims, if the insurer instructs a loss adjuster or approved contractor to carry out the repair, you pay the excess directly to the contractor at the end of the work. For contents claims, the insurer typically deducts the excess from the settlement payment or asks you to pay it before issuing a replacement item or cash settlement.

If you make separate claims for buildings and contents arising from the same event (for example, a burst pipe damages both the ceiling plaster and your furniture), most insurers charge only one excess (usually the higher of the two) rather than stacking both, but this is not guaranteed. Read your policy wording or ask your insurer to confirm.

Step 5: When You Pay the Excess

The excess applies per claim event, not per policy year. If you make three separate claims in one year, you pay the excess three times.

You do not pay the excess when you buy or renew the policy. The excess is deducted or collected only when the insurer settles an actual claim.

If the claim cost is lower than your total excess, you pay the entire cost yourself and the insurer pays nothing. In this scenario, many policyholders choose not to notify the insurer at all, because formally logging a claim (even if it results in no payout) can still affect your renewal premium and your ability to answer the “Have you made any claims?” question truthfully on future applications.

However, if the incident may give rise to a claim against you (for example, a third party alleges you caused damage), you must notify your insurer promptly under the policy terms, even if your own damage is below the excess. Failing to notify can void your cover for that incident.

Step 6: How to Choose Your Voluntary Excess

Choosing the right voluntary excess balances premium savings against the risk of facing a large out-of-pocket bill at claim time.

Run the Numbers

When comparing quotes, request a premium with £0 voluntary excess and again with £100, £250, and £500 voluntary excess. Note the saving at each level.

For example, on a motor policy you might see:

  • £0 voluntary excess: £680 annual premium
  • £100 voluntary excess: £630 (£50 saving)
  • £250 voluntary excess: £590 (£90 saving)
  • £500 voluntary excess: £560 (£120 saving)

The saving often tapers off beyond £250 or £500, and the marginal premium reduction does not justify the additional out-of-pocket risk.

Consider Your Emergency Fund

Ask yourself whether you could comfortably pay the total excess (compulsory plus voluntary) tomorrow if you needed to claim. If your compulsory excess is already £400 and you add £500 voluntary, you need £900 in accessible savings to cover a claim without hardship.

If your emergency fund is limited, keep the voluntary excess low or at zero. The premium saving is not worth the stress and financial disruption of being unable to pay the excess when a claim arises.

Weigh Claim Likelihood

If you drive in congested urban areas, park on the street, or have a high-value vehicle, the likelihood of a motor claim is higher. In that case, a lower voluntary excess may be prudent.

Conversely, if you drive very low mileage, park in a secure garage, and have a strong no-claims bonus, you may feel comfortable taking a higher voluntary excess in exchange for a lower premium.

For home insurance, consider your property’s exposure to common perils. If you live in a flood-risk area or have aging plumbing, you may prefer a lower excess.

Review Annually

Your financial situation and risk profile change. At each renewal, re-evaluate your voluntary excess. If your savings have grown or your circumstances have changed, you may choose to raise the voluntary excess to save on premium, or lower it if your budget is tighter.

Practical Tips

  • Check your policy schedule carefully: It lists all applicable excesses. Do not assume the figure quoted online is your only excess; young driver, conviction, and peril-specific excesses may apply on top.
  • Ask about excess protection or waiver: Some insurers offer an optional excess protection add-on (for an additional premium) that refunds your excess if you make a claim. Evaluate whether the cost of the add-on outweighs the excess itself; often it does not represent value.
  • Keep records of your excess level: When you renew or switch insurer, note the total excess on your new policy. Accidentally doubling your excess without realising it can leave you unable to afford a claim.
  • Consider protected no-claims bonus separately: A protected NCB prevents your discount from dropping after a claim, but you still pay the excess and the base premium may rise. Excess and NCB protection are independent features.

Common Mistakes to Avoid

  • Raising voluntary excess too high for short-term savings: Saving £80 on your annual premium by adding £500 voluntary excess is a false economy if you cannot afford the £500 when you need to claim.
  • Forgetting that excesses stack: A £200 compulsory excess plus a £300 voluntary excess plus a £400 young driver excess totals £900, not £300. Many young drivers discover the true figure only when they call to claim.
  • Not checking peril-specific excesses: A standard £100 excess does not mean you pay only £100 for a subsidence claim; the subsidence excess (often £1,000 or more) applies instead.
  • Assuming one excess covers multiple claims: Each claim event triggers a new excess payment. Three claims mean three excess payments, even within the same policy year.
  • Confusing excess with premium: The excess is not an instalment or deposit on your premium. It is a separate cost, payable only if you claim.

Frequently Asked Questions

Can I negotiate the compulsory excess?
No. The compulsory excess is set by the insurer’s underwriting rules and applies uniformly to the risk profile you present. You can shop around for an insurer with a lower compulsory excess for your circumstances, but you cannot negotiate it on an individual policy.

Does paying a higher excess reduce my premium every year?
Yes, provided you select the same voluntary excess at renewal. The discount applies each year you maintain that excess level. However, the absolute premium will still fluctuate based on claims inflation, changes to your risk profile, and market conditions.

What happens if I cannot afford to pay the excess?
The insurer will not proceed with settling your claim until you pay your share. In the case of a repair arranged by the insurer, the repairer will not release the vehicle or complete the work until you pay the excess. If you cannot pay, your claim remains unsettled, and you bear the full cost of the damage yourself.

If the other driver is at fault, do I still pay my excess?
Initially, yes. Your insurer settles your claim and you pay the excess. Your insurer then pursues the at-fault party’s insurer to recover the claim cost and your excess. Once recovery succeeds (which can take months), your insurer refunds your excess to you. If recovery fails or is only partial, you may not get your excess back.

Can I change my voluntary excess mid-term?
Most insurers allow a mid-term adjustment, but they will recalculate your premium and may charge an administrative fee. The new excess applies only to claims that occur after the change takes effect, not to incidents that happened before.

Conclusion

Understanding how excess amounts work on UK home and car insurance empowers you to make informed decisions at quote and renewal time. The excess is not merely a box to tick; it directly affects both your annual premium and your out-of-pocket costs if you need to claim. Know the difference between compulsory and voluntary excess, check which additional excesses apply to your policy (young driver, conviction, subsidence, flood), and choose a voluntary excess level that balances premium savings against your ability to pay the total excess comfortably if a claim arises.

Before your next renewal, review your current excess on your policy schedule, compare quotes with different voluntary excess levels, and confirm that the total excess (compulsory plus voluntary, plus any age or peril loadings) is affordable from your emergency fund. If you are unsure which excess level suits your circumstances, or if your policy wording is unclear about how multiple excesses stack, consider speaking to an FCA-authorised insurance adviser or broker who can walk you through the options and help you find a policy that meets your needs.
