Every insurance policy covers some things and not others. The things it does not cover are called exclusions. They are written into the policy wording, and they are just as important as what is covered, because an exclusion is exactly where a claim can be declined. Understanding exclusions, and the related conditions and disclosure rules, is how you avoid the nasty surprise of finding out at claim time that you were not covered for the very thing that happened.
While every policy differs, some exclusions appear again and again. Knowing the common ones helps you read any policy more sharply.
| Common exclusion | What it means |
|---|---|
| Wear and tear | Gradual deterioration and ageing are not covered; insurance is for sudden events |
| Lack of maintenance | Damage from failing to maintain something may be excluded |
| Deliberate or reckless acts | Damage you cause on purpose or through recklessness is not covered |
| Pre-existing conditions | Problems that existed before cover began, common in health and travel |
| Specific events | Certain named events may be excluded or need add-on cover |
| Unoccupied or misused property | Cover can be limited if conditions are not met |
A key idea is that insurance covers sudden, unexpected events, not gradual deterioration. A roof that wears out over decades, or an appliance that ages, is maintenance, not an insured event. Mixing these up is a common reason claims are declined. See our guide on insurance basics.
When you take out insurance, you generally must tell the insurer the things that matter to the risk, honestly and completely. This is called disclosure. If you fail to disclose something important, or get it wrong, the insurer may be able to decline a claim or even treat the policy as if it never existed. Disclosure is one of the most important and most overlooked parts of being properly covered.
Beyond exclusions, policies have conditions you must meet to stay covered, such as keeping a property secured, maintaining it reasonably, or notifying the insurer of changes. Failing to meet a condition can affect a claim even if the event itself is covered.
If a claim is declined and you believe it should be covered, you can ask the insurer to explain which exclusion or condition applies, and you can dispute it. Every insurer belongs to a free dispute resolution scheme you can use if you cannot resolve it directly. Keep your documents and the policy wording to support your case.
See our guides on how insurance claims are assessed and how premiums are calculated. Final word: exclusions are what a policy does not cover, and they decide claims as much as the cover does. Read the wording, disclose honestly, meet the conditions, and check the exclusions match your needs. Doing so turns insurance from a gamble into reliable protection.
