A household worker is a worker you employ in and about, or in connection with, a private dwelling or the grounds of the dwelling. If you employ a household worker, you are required to take out a Household worker insurance policy with us.
The premium is currently set at $45 (including taxes) during the period of 1 January 2011 to 31 December 2012. This premium is non-refundable and is not pro-rated if you take out or cancel the insurance mid-term.
Holding an household workers’ insurance policy means that you are covered against the costs of compensating a household worker who is injured while working for you.
