Home Insurance Excess Explained: Compulsory vs Voluntary
Every home insurance claim in the UK typically involves paying an excess, the portion of the claim cost you contribute yourself before the insurer pays the remainder. Understanding how compulsory and voluntary excess work, and how they interact, helps you make more informed decisions when buying a policy.
Compulsory Excess
Compulsory excess is set by the insurer and reflects their assessment of risk for your particular property and circumstances; it is not something you can negotiate away entirely. It might be higher for properties in flood risk areas, for certain types of claim such as subsidence, or for policyholders with a history of previous claims. This figure is fixed as a condition of the policy being offered to you at all.
Voluntary Excess
Voluntary excess is an additional amount you choose to add on top of the compulsory excess, in exchange for a reduction in your premium. By agreeing to pay more towards any claim yourself, you are taking on more of the financial risk, which insurers reward with a lower price. The total excess payable on a claim is the sum of both the compulsory and voluntary elements.
How Excess Affects Your Premium
Generally, the higher your voluntary excess, the lower your premium, though the relationship is not always perfectly linear and varies between insurers. Our voluntary excess calculator can help you estimate the potential saving before requesting quotes at a few different voluntary excess levels, since the savings can vary considerably depending on the insurer's pricing model.
Choosing the Right Excess Level
The key principle when choosing a voluntary excess is affordability: never set it higher than you could comfortably pay out of savings if you needed to make a claim. An excess that saves you money on the premium but leaves you unable to actually afford a claim defeats the purpose of having insurance in the first place. Consider your household's financial buffer honestly before opting for a higher excess purely to reduce the headline premium.
Excess and Small Claims
Because the excess is deducted from every claim, it is often not worth claiming for damage that costs only slightly more than your total excess, since the payout may be minimal after the deduction, and making a claim can affect future premiums regardless of the amount paid out. Many policyholders choose to pay for minor repairs themselves and reserve insurance claims for more significant losses.
Different Excess for Different Claim Types
Some home insurance policies apply different excess levels depending on the type of claim, for example a higher excess for subsidence or escape of water claims compared with theft or fire. Always check your policy schedule for these variations rather than assuming a single flat excess applies across every possible claim scenario, since this can significantly affect what you would actually receive from a successful claim.
How Multiple Claims in One Policy Year Affect Excess
If you need to make more than one claim within the same policy year, it is worth understanding that the excess typically applies separately to each individual claim, rather than being a single amount deducted once across the whole year. This means two smaller claims within the same year could each incur the full excess, potentially making the combined out-of-pocket cost more significant than a single larger claim might have been. This is one of several reasons it is worth thinking carefully before claiming for relatively minor damage, weighing the excess and potential impact on future premiums against simply covering a smaller repair cost yourself.
Excess-Free Policy Features
A small number of home insurance policies or specific add-ons offer excess-free claims for particular types of loss, such as certain accidental damage events, though this is relatively uncommon and usually reflected in a higher overall premium. If avoiding an excess entirely for specific risks is important to you, it is worth asking insurers directly whether such options exist, rather than assuming every policy follows an identical excess structure.
Understanding exactly how your excess works, and choosing a level that balances premium savings against genuine affordability, is one of the simplest ways to make sure your home insurance works properly for you when you actually need it.
