If the broker says there will be an increase in the premium because of the home business are we able to directly levy the business owner with the additional fee once quantified by the broker?
In both Victoria and Nsw, if a part of the insurance premium is raised due to the activity in one lot, then that owner can be charged the difference.
However, I can’t see that an insurer would justify an increased premium in the circumstances you described. Good that you came clean, though. Failure to report can void some insurances, even if the claim has nothing to do with the unreported issue.
