What is GAP Insurance and How Does It Work?

GAP Insurance covers the shortfall between your motor insurer’s total loss payout and a higher value, such as your original purchase price, outstanding finance or the cost to replace your vehicle.
It only applies when your vehicle is written off or stolen and declared a total loss by your motor insurer.

How GAP Insurance Works

GAP Insurance is a financial top-up that bridges the 'GAP' in the event of a total loss, between your motor insurance settlement and either the original invoice price (Return to Invoice), the amount outstanding on finance (Finance/Contract Hire), or the cost to replace the vehicle (Vehicle Replacement).

 

GAP Insurance runs alongside your main, comprehensive motor insurance policy and can be utilised only if your motor insurer writes off the vehicle as a total loss. This can happen in several ways:

How GAP Insurance works with car insurance in a write off or theft

Following an incident with your vehicle, it is for your motor insurer to decide whether to repair, replace or write off your vehicle as a total loss. If the decision is made to write off the vehicle, then your motor insurer will offer you a market value settlement for the vehicle. This is the amount that it will cost you to replace the car with the same age, mileage and specification as your vehicle before it was written off. 

 

For example, if you paid £25,000 for your car and your motor insurer pays £15,000 after a write-off, GAP Insurance could cover the £10,000 shortfall, depending on your policy type and claim limit.

 

In simple terms, GAP Insurance works like this:

  1. Your car is written off or stolen.
  2. Your motor insurer pays the current market value.
  3. compares that payout with a higher value, such as your original purchase price, replacement cost or finance settlement.
  4. The difference is the GAP claim.

 

The exact amount your GAP policy pays will depend on the type of cover you have and your policy limits.

 

Why GAP Insurance exists

 

Cars lose value quickly, especially in the first few years. Your motor insurer will only pay the current market value, which is often much lower than what you paid or still owe.

 

Even if you don't have any outstanding finance on the vehicle, you would still be left with less than the original price you paid, and therefore lose a lot of the equity you had in it. This could then force you to take out finance for your next vehicle or use your savings to replace it. With GAP Insurance, you can protect yourself from any financial implications should the vehicle be declared a total loss, either by clearing the finance off, returning you to the original purchase price, or topping you up to the cost to replace the vehicle with another 'like for like' model. 

 

GAP Insurance only works if your motor insurer accepts the total loss claim. If the motor insurance claim is declined or reduced, the GAP claim can be affected too.

 


The same total loss can produce very different payouts depending on the type of cover you choose. Return to Invoice GAP, Vehicle Replacement GAP and Lease & Contract Hire GAP all work slightly differently.

 

Combined Return to Invoice GAP Insurance

Combined Return to Invoice GAP can cover the difference between your motor insurance settlement, if the vehicle is written off, and the higher of:

  • the original invoice price paid
  • the outstanding finance settlement

This policy, under the circumstances used above, will top you up from your motor insurance settlement of £10,000 back up to the original invoice price of £25,000. Within the £25,000, you will clear any outstanding finance, and the balance is yours to use to replace the vehicle. 

 

Dealer and Factory fitted extras? GAP Insurance typically covers items listed on your invoice, but accessories added later are not normally included in a GAP claim. 


Lease & Contract Hire GAP Insurance

 

Lease and Contract Hire GAP can cover the difference between your motor insurance settlement, if the vehicle is written off, and the outstanding settlement on your lease.

 

You can also have, or opt for, deposit protection cover. This can cover some, or all of your initial rental payment depending on the policy limits. 

 

This is a specific style of GAP Insurance for leases, where you do not have the option to own the vehicle written in to your lease agreement. This is not suitable for a Personal Contract Purchase or Hire Purchase agreement, where you can own the vehicle. 

 


 

Combined Return to Invoice & Vehicle Replacement GAP

Provided by Total Loss GAP

 

Vehicle Replacement GAP, particularly from Total Loss GAP, can be regarded as the most comprehensive form of GAP Insurance. 

Rather than you having to choose one of the above, instead, we combine the three different types into one all-inclusive, comprehensive policy. Simply put, should the worst happen and your vehicle is declared a total loss, we will bridge the GAP between your own motor insurance settlement and the HIGHER of either the original invoice price you have paid (Return to Invoice), the cost to replace the vehicle with a 'like for like' vehicle (Vehicle Replacement) or the amount outstanding on finance if applicable.

 

Again, within any settlement, the amount owing on the finance is always cleared, and the money left over always comes back to you.

Is it worth having GAP Insurance if you don't have any finance? 

 

This is one of the most often asked questions we get. Yes, it is still worth having GAP Insurance even if you don't have any finance attached to the vehicle. The reason being, you will have the ability to protect the 100% equity you have placed in the vehicle or protect your ability of purchasing the same vehicle again, if the vehicle is declared a total loss. As explained above, if you have purchased your vehicle outright, you have the ability to protect the original invoice price you have paid for the vehicle or the cost to replace it, even if that price has increased. 

 

Like any form of insurance, you always have to weigh up the risk against the implications of something happening. Yes, the chances are that your vehicle won't be written off, however, could you afford to face the financial implications should it happen? Because the chances are very slim, the policy premium quoted doesn't have to be a lot of money. If you are wondering how much you should be paying for GAP Insurance? our current average policy price is approximately £99.99 for three years cover.
