Accidental damage sounds obvious until it isn’t
Accidental damage feels like the most human part of home insurance. Spilled paint. A cracked sink. A foot through the loft ceiling. Real life, in other words. That’s why people are often surprised to discover it isn’t always included.
Accidental damage sits slightly apart from standard home insurance, even though it’s one of the most commonly misunderstood parts of a policy.

What insurers usually mean by accidental damage
Accidental damage refers to sudden, unintended harm caused by everyday activity. No storm. No fire. No theft. Just an unfortunate moment.
That definition matters, because insurers draw a clear line between accidents and anything that develops over time.
Is accidental damage included as standard?
Sometimes, but not always. Many policies include accidental damage for certain items by default, particularly on contents. Others treat it as an optional extension.
Buildings accidental damage is more often optional than contents accidental damage. That difference catches people out.
Buildings accidental damage versus contents
Accidental damage to buildings usually covers things like broken windows, damaged sanitaryware, or drilled-through pipes.
Contents accidental damage tends to cover mishaps involving furniture, electronics, and personal belongings. Even then, limits apply.
Why insurers separate accidental damage
Accidents happen frequently. Insurers know this. Including accidental damage as standard would increase claims frequency and push premiums up.
By making it optional, insurers allow people to choose whether they want cover for everyday mishaps or only for major insured events.
Common assumptions that cause problems
- That accidental damage is always included
- That buildings and contents are treated the same
- That all breakages count as accidental
- That wear-related failures qualify
Most claim disputes start with one of these assumptions.
What accidental damage usually doesn’t cover
Accidental damage doesn’t replace maintenance. It doesn’t cover deterioration, poor workmanship, or items failing due to age.
Damage caused deliberately, even without malicious intent, is also commonly excluded. Intention matters.
Accidental damage outside the home
Some policies extend accidental damage to personal possessions away from the property. Others restrict it to the home only.
Dropping a phone at home and dropping it in the street can lead to very different outcomes depending on the policy wording.
Excesses and accidental damage claims
Accidental damage claims often carry the same excess as other claims, sometimes more. Smaller claims can be swallowed entirely by the excess.
This is why some people carry the cover for peace of mind rather than frequent use.

Families, pets, and everyday risk
Homes with children or pets tend to see more accidental damage claims. Insurers know this and price accordingly.
That doesn’t make accidental damage essential, but it does change how useful it may be in practice.
Adding accidental damage later
Accidental damage can usually be added at policy start or renewal. Adding it mid-term is sometimes possible, but terms vary.
Damage that has already happened won’t be covered retrospectively.
Why policy wording matters more than the label
Two policies both described as including accidental damage can behave very differently. Definitions, limits, and exclusions do the real work.
Accidental damage exists to catch everyday mishaps, but only where it’s clearly included and properly defined. That detail, not the headline, decides what happens when something breaks.
