Find-a-person-to-do-anything service Airtasker is handy for everything from finding IT help to having Lord Of The Fries delivered to your office. In a useful boost, Airtasker is now providing a basic insurance policy for its workers which covers them for public liability.
In practice, that means that if someone causes damage to your property while completing a task, the insurance policy should cover it. There are a number of specific exclusions (childcare and builders amongst them, though basic handyman tasks are covered). There's no charge to workers for the insurance, though if they do need to make a claim, an excess will be payable.
