GAP insurance

If your car is stolen or written-off, with comprehensive insurance you will receive a payment that covers the total loss cost of your vehicle. This payment is based on the market value of your car at that particular time; this could be a lot less than what you paid for it. This may not be a problem if you have already fully paid for your car, but if you are making payments through a finance package you may find yourself out of pocket. If the current market value of your car is less than what you paid for it, your insurance may not cover the repayments you still owe. This is where GAP insurance comes in.

You can only take out GAP insurance if your car is covered by a comprehensive insurance policy.
