Household insurance covers the things in your home and/or the building itself. It can't replace the memories you've made over the years, but it can help you replace your things if they get damaged or lost. Household insurance covers most of your belongings up to a certain amount, which is stated at the beginning of the policy. You pay a monthly premium for this coverage.
Most standard homeowner's insurance policies will cover damage caused by things like fire, theft, flooding, and storms. Most standard policies don't cover accidental damage and you have to buy it separately. However, it's worth reading the fine print because sometimes accidental damage to things like TV screens and furniture is covered.
When looking for home insurance, you should try to find a "new for old" policy. This means that if you have to make a claim, you will get the value of the item now, not when you bought it. Most household contents insurance policies will also cover you up to a certain point if someone dies in your home because of a fire or an accident, but again, you should read the fine print and find out what isn't covered.
Before getting a quote, you should make a full list of everything in your home. If you want the cheapest quotes on homeowner's insurance, you should let a specialist broker do the work of shopping around for you. Remember that if you have any high-value items, they might not be covered by a standard policy, so make sure to check before you sign on the dotted line.
