Your excess is the amount you contribute when you want to make a claim. Once your claim is accepted, your insurer covers the rest. For example, you’re paying $100 a month for home insurance when there’s an insured event, such as a fire. Your home is damaged in the fire, and it’s estimated to cost $100,000 to make the necessary repairs. According to your policy, you might need to pay $800 towards this claim – that’s an excess.
If you want to reduce your monthly $100 premium, you might be able to increase your basic excess within a given range, which could reduce your premium.1 However, increasing your excess could also mean that you're less likely to make claims for small amounts. There's little point making a claim to replace a $500 window if the excess is $1,500 – you'll need to pay $1,500 to get $500 back. Before making a decision, consider the benefits and costs of increasing your excess to reduce your premium.
