There are hundreds of examples that illustrate why businesses big and small need the coverage provided by public liability companies. Here is one scenario: as the owner or operator up a plumbing company, you have been called to a customer's home to repair a leak to their kitchen plumbing.

You will be required to provide financial compensation for the resulting damage to their property.
