A home insurance excess is the amount you generally pay towards an accepted claim before your insurer covers the remaining costs, subject to the policy terms. You may be able to choose an excess, with a higher excess often reducing the premium but increasing your upfront cost if you claim. Make sure the amount is affordable and check whether the policy applies additional excesses for events such as storms, floods or certain types of damage. Compare policies carefully and confirm the available options and final premium with the insurer.
