What losses does the indemnity insurance policy cover?

In the unlikely event that you need to claim upon the insurance, the policy covers:
  • damages, compensation, costs and/or expenses (but not fines or other penalties) which you have to pay because of an Order;
  • the amount by which the value of the Property is reduced by the effect of an Order;
  • any other costs and expenses you incur with the Insurer’s written consent because of an Insured Risk.

The definition of Order is: A decision made by a court (or another recognised body with authority to make a decision that is legally binding on you) in relation to an Adverse Matter.

What isn't covered within the indemnity insurance?

  • Future losses when you sell because your buyers aren't prepared to accept building works without retrospective sign off. This can mean you have to sell the property lower than the current market value because your new buyers aren't prepared to take the risk
  • Personal injury from being injured due to faulty works. For example, the electrics aren't installed to correct standards and either give you an electric shock or the circuit gets over loaded and causes a fire.
