Perhaps the biggest benefit of all is preparedness.
You can't know when an accident, theft, fire or severe storm might occur. But you can decide beforehand how much financial risk you're comfortable carrying yourself.
That's what insurance is ultimately designed to help with: transferring specified financial risks to an insurer in return for a premium, subject to the policy terms.
Before cancelling cover because you're trying to reduce monthly expenses, consider the financial impact you could face if you had to replace or repair an important asset yourself.
If affordability is becoming difficult, speak to your insurer about your options before simply cancelling your policy.
