Introduction
Excess is one of the most important, and most commonly misunderstood, parts of a home insurance policy. It directly affects both what you pay upfront for cover and what you'd actually receive if you ever needed to claim, yet many policyholders only think about it properly at the moment they're making a claim, when it's too late to make a different choice.
This guide explains exactly how home insurance excess works in the UK, including the distinction between compulsory and voluntary excess, why buildings and contents cover are often treated separately, and why certain claim types carry their own specific excess. Our Home Insurance UK guide covers buildings and contents cover more broadly, and our Car Insurance Excess Explained UK guide covers how the same underlying concept works for motor insurance.
Key Terms Explained
- Excess
- The amount you agree to pay towards an accepted claim before your insurer covers the remaining cost.
- Compulsory Excess
- A fixed excess amount set by the insurer as a standard condition of the policy, which you generally cannot remove or reduce.
- Voluntary Excess
- An additional amount you choose to add on top of the compulsory excess, usually in exchange for a reduced premium.
- Buildings Cover
- Insurance protecting the physical structure of your home, including walls, roof and fixed fittings.
- Contents Cover
- Insurance protecting your belongings inside the home, separate from the structure itself.
- Subsidence
- Downward movement of the ground beneath a property, a specific and often more complex type of buildings insurance claim.
Compulsory vs Voluntary Excess
Understanding this distinction is the foundation for everything else in this guide.
Compulsory Excess
This is a fixed amount set by the insurer as a standard term of your policy. It reflects the insurer's own underwriting approach and typically cannot be negotiated away, though it can vary between insurers and policies.
Voluntary Excess
This is an additional amount you actively choose when taking out or renewing your policy, on top of the compulsory excess. Choosing a higher voluntary excess generally reduces your premium, since you're agreeing to bear more of the cost of a claim yourself, while choosing a lower voluntary excess, or none at all, generally means a higher premium in exchange for less upfront financial exposure if you claim.
How the Two Combine
When you make a claim, the total excess you pay is usually the compulsory and voluntary amounts added together, rather than just one or the other. This total is deducted from your settlement, or you may be asked to pay it directly, depending on how the insurer handles the specific claim.
Buildings vs Contents Excess
Many UK homeowners hold a combined buildings and contents policy, but the excess isn't always identical across both.
Why Insurers Separate Them
Buildings and contents claims involve genuinely different types of risk, cost profiles and investigation processes, so insurers often set separate excess amounts for each, even within a single combined policy.
What This Means in Practice
A claim affecting only your belongings, such as a stolen laptop, may carry a different excess to a claim affecting the structure of your home, such as storm damage to your roof. If a single incident affects both buildings and contents, such as a fire, some policies apply only the higher of the two excesses, while others may apply both separately; this varies by insurer, so checking your specific policy wording matters.
Checking Your Own Policy
Your policy schedule should clearly set out the excess that applies to buildings claims and the excess that applies to contents claims separately. If this isn't clear from your documents, contacting your insurer directly to confirm is worthwhile before you ever need to rely on it.
Claim-Specific Excesses
Beyond the general buildings and contents split, certain claim types commonly carry their own specific excess.
| Claim Type | Typical Excess Treatment |
|---|---|
| Subsidence | Commonly a higher specific excess, reflecting greater investigation and remediation complexity |
| Flood | May carry a specific excess in flood-risk areas, sometimes with Flood Re-related considerations |
| Escape of water | Sometimes subject to its own excess or conditions given how common these claims are |
| Accidental damage | Often an optional extra with its own separate excess if added to the policy |
| Standard theft or storm damage | Usually the policy's standard buildings or contents excess applies |
Why Subsidence Is Treated Differently
Subsidence claims typically require specialist investigation, ongoing monitoring, and sometimes significant remedial work such as underpinning, all of which make them more complex and costly to handle than many other claim types. This is why insurers commonly apply a higher specific excess to subsidence claims rather than the policy's general standard excess. Our Subsidence Insurance UK guide covers this specific topic in full depth.
Flood-Prone Areas
Properties in areas with a higher flood risk may see specific excess arrangements or conditions applied to flood-related claims, and the Flood Re scheme exists specifically to help make flood cover more available and affordable for eligible households. Always check exactly how your own policy treats flood claims rather than assuming standard terms apply automatically.
Accidental Damage as an Add-On
Accidental damage cover, such as an accidentally spilled drink ruining a carpet, is often sold as an optional extra rather than included as standard, and frequently carries its own separate excess if you choose to add it to your policy.
Choosing the Right Excess Level
There's no single correct answer here, since it depends entirely on your own financial circumstances and risk tolerance.
Affordability Comes First
Setting an excess higher than you could genuinely and comfortably afford to pay at short notice defeats much of the purpose of having insurance in the first place. If a genuine claim arose and you struggled to cover the excess, the cover itself becomes considerably less useful in practice.
Consider Your Own Claims History and Risk
If you live somewhere with a lower risk of specific claim types, such as flood or subsidence, a higher voluntary excess may represent better value than if you live somewhere genuinely more exposed to those specific risks.
Review at Every Renewal
Your circumstances, savings position and risk tolerance can all change over time, so it's worth revisiting your chosen excess level at each renewal rather than leaving it unchanged indefinitely without reconsidering whether it still suits you.
Multiple Claims in the Same Policy Year
This is a common point of confusion worth clarifying directly.
Excess Applies Per Claim, Not Per Year
Excess is generally applied separately to each individual accepted claim, rather than once across the entire policy year. If you made two genuinely separate claims within the same year, for example a burst pipe in spring and a break-in later that year, you would typically pay the relevant excess on each claim individually.
Why This Matters for Small Losses
Because each claim carries its own excess, it's worth thinking carefully before claiming for a loss that's only modestly above your excess amount, since the net benefit of claiming may be smaller than it first appears once the excess is deducted.
When and How You Actually Pay Excess
The practical mechanics vary slightly by insurer and claim type.
Deducted From Your Settlement
In many cases, the excess is simply deducted from whatever settlement amount the insurer pays out, meaning you never need to pay it separately upfront.
Paid Directly to a Repairer
In other cases, particularly where an insurer arranges a repair directly with a approved contractor, you may be asked to pay your excess directly to the repairer as part of the arrangement, rather than through a deduction from a cash settlement.
Confirming the Process With Your Insurer
If you're ever unsure how excess will be handled for a specific claim, asking your insurer directly at the point of claiming, rather than assuming, avoids any confusion about what you'll actually need to pay and when.
Real-World Examples
Case Study: Separate Buildings and Contents Excess
A homeowner's washing machine leak damages both the kitchen flooring, a buildings matter, and several items of contents stored nearby. Checking their policy schedule, they find separate excess amounts apply to the buildings and contents elements of the same incident, and confirm with their insurer exactly how both will be applied before proceeding with the claim.
Case Study: A Higher Subsidence Excess
A homeowner notices new cracking in an exterior wall and contacts their insurer, who confirms it will be investigated as a potential subsidence claim. They discover their policy applies a significantly higher specific excess to subsidence claims compared with their standard buildings excess, which they hadn't previously been aware of.
Case Study: Deciding Not to Claim
A homeowner suffers minor storm damage to a garden fence, with a repair cost only slightly above their voluntary excess. After calculating the modest net benefit once the excess is deducted, and considering the potential effect on their claims history, they choose to pay for the repair themselves rather than making a formal claim.
Common Mistakes to Avoid
- Assuming buildings and contents excess are automatically the same amount.
- Not checking whether your policy applies a higher specific excess to subsidence or flood claims.
- Setting a voluntary excess higher than you could genuinely afford at short notice.
- Assuming excess is applied only once per policy year rather than per individual claim.
- Claiming for a loss only marginally above the excess without weighing the real net benefit.
- Not confirming how and when excess will actually be paid before proceeding with a claim.
Common Myths
- Myth: Buildings and contents always share the same excess. Many combined policies set these separately, and it's worth checking rather than assuming.
- Myth: Excess only applies once per year, however many claims you make. It's generally applied separately to each individual accepted claim.
- Myth: A higher excess is always the smarter financial choice. It only makes sense if you could genuinely and comfortably afford to pay it if a claim arose.
- Myth: Subsidence claims are treated exactly like any other buildings claim. They commonly carry a specifically higher excess given their complexity.
Frequently Asked Questions
What is home insurance excess?
Excess is the amount you agree to pay towards a claim before your insurer pays the rest. Home insurance policies typically have separate excesses for buildings and contents cover, and often set higher excesses for specific claim types such as subsidence or flood.
What's the difference between compulsory and voluntary excess on home insurance?
Compulsory excess is a fixed amount set by the insurer that you cannot change. Voluntary excess is an additional amount you choose to add on top, generally in exchange for a lower premium. The total excess you pay on a claim is usually the compulsory and voluntary amounts combined.
Are buildings and contents excess the same amount?
Not necessarily. Many combined buildings and contents policies set separate excess amounts for each type of cover, so a claim affecting only your contents may carry a different excess to one affecting the structure of your home.
Why is the excess for subsidence claims often higher?
Subsidence claims tend to be more complex and costly to investigate and remediate than many other claim types, which is why insurers commonly apply a higher specific excess to subsidence claims compared with the policy's standard excess.
Do I pay excess on every home insurance claim?
Generally, yes, if the claim is accepted, though some optional extras or specific policy features may waive the excess in particular circumstances. Check your policy wording, since this varies by insurer and policy.
Can I choose not to claim if the loss is close to my excess amount?
Yes, you're not obliged to make a claim. Some policyholders choose to pay for a minor repair themselves if the cost is close to or below their excess, since a claim could also affect future no-claims history or renewal terms, depending on the insurer.
How do I choose the right excess level for my home insurance?
Balance the premium saving from a higher voluntary excess against what you could genuinely afford to pay unexpectedly if you needed to claim. Setting an excess higher than you could comfortably afford defeats much of the purpose of having cover in the first place.
Does a higher excess reduce my home insurance premium?
Generally, yes, a higher voluntary excess typically reduces your premium, since you're agreeing to cover more of the cost of smaller claims yourself. The exact effect varies between insurers.
What happens if I have multiple claims in the same policy year?
Excess is generally applied separately to each individual claim, not once per policy year, so multiple unrelated claims within the same year would typically each carry their own excess.
Is escape of water treated differently from other home insurance claims?
Escape of water, such as a burst pipe, is usually covered under standard buildings and contents policies, but some insurers apply their own specific excess or conditions to this claim type given how common and potentially costly water damage claims can be.

Conclusion
Home insurance excess is a genuinely important part of your cover, not just a technical detail buried in the policy wording. Understanding the difference between compulsory and voluntary excess, checking whether your buildings and contents cover carry separate amounts, and knowing which claim types attract a higher specific excess all help you make a more informed choice, both when setting up your policy and when deciding whether to claim.
Choosing an excess level that genuinely balances premium savings against real affordability, reviewed at each renewal rather than left unchanged indefinitely, is the single most practical step every homeowner can take to get this right. Homeowners carrying a higher voluntary excess may also want to consider a separate excess protection insurance policy, which can reimburse some or all of the excess paid on a valid claim.
