Landlords have a legal responsibility to provide tenants with heating and hot water, so a broken boiler is always an urgent issue. Most standard building insurance policies will not cover boiler breakdowns, but some providers offer this as an optional extra. If a broken boiler has caused other issues in the property, such as a leak, then damage caused by this could be covered even if the appliance itself is not. You could be covered for a broken boiler if the appliance is damaged by fire, flooding or another event included in your policy.
