GAP Insurance Explained: Your Questions Answered
21 August 2026
If your car is written off or stolen, your comprehensive motor insurer will usually pay its current market value at the time of the claim.
Depending on how much the vehicle has depreciated, that amount could be less than you originally paid, less than the cost of replacing it with an equivalent vehicle, or less than the amount still outstanding on a finance or lease agreement.
That is where GAP insurance can help.Below, we answer some of the most common questions drivers have about GAP insurance, how it works and the different types of cover available.
GAP stands for Guaranteed Asset Protection.GAP insurance is designed to help protect against the financial shortfall that can arise if your vehicle is declared a total loss following theft, accident, fire or another insured event.
Your comprehensive motor insurer will normally settle your claim based on the vehicle’s market value at the time of the loss. GAP insurance can provide additional protection depending on the type of policy you have chosen.
Why could there be a shortfall after my motor insurer pays out?
Cars can lose value over time through depreciation.For example, you may have paid £30,000 for a vehicle, but if it is written off at a later date your motor insurer may calculate that its current market value is £22,000.
That difference is one of the reasons drivers consider GAP insurance.The exact protection available will depend on the type of GAP policy you have.
What are the main types of GAP insurance?
There are several different types of GAP insurance, designed for different circumstances.
Back to Invoice GAP insurance is designed to help bridge the difference between your comprehensive motor insurer’s settlement and the original invoice price of the vehicle, subject to the terms and limits of the policy.
You may also hear this type of cover referred to as Return to Invoice or RTI GAP insurance.
Vehicle Replacement GAP insurance
Vehicle Replacement GAP insurance can help cover the difference between your motor insurer’s settlement and the cost of replacing your vehicle with an equivalent new vehicle, subject to the policy terms. This can be particularly relevant where the price of the equivalent replacement vehicle has increased since the original vehicle was purchased.
Contract Hire GAP insurance is designed for vehicles on qualifying lease or contract hire agreements.If the vehicle is declared a total loss, there may be an outstanding amount owed to the leasing company after the comprehensive motor insurance settlement.
Contract Hire GAP insurance can help cover eligible shortfalls, subject to the terms of the policy.
Agreed Value GAP insurance may be appropriate in circumstances where the amount being protected is based on an agreed value rather than the vehicle’s original invoice price.
Eligibility and cover will vary, so it is important to check the policy terms.
Is Finance GAP insurance the same as GAP insurance?
“Finance GAP” or “Loan GAP” are terms sometimes used more generally to describe GAP cover that helps protect against a potential shortfall involving vehicle finance.
Different policies work in different ways, however, so it is important not to assume that all GAP products offer the same protection. The right type of cover will depend on how you bought or financed the vehicle and what you want the policy to protect.
Do I need GAP insurance if I bought my car on PCP?
A PCP agreement does not automatically mean that you need GAP insurance, but it is one of the situations in which drivers may want to consider the potential financial consequences of a total loss.If your vehicle is written off, your motor insurer will normally pay its current market value.
Depending on the stage of your PCP agreement, there may be a difference between that settlement and the amount required under your finance agreement, or between the settlement and another value you wish to protect.
It is important to check both your finance agreement and the terms of any GAP policy before deciding whether cover is suitable for you.
Do I need GAP insurance if I lease my car?
Drivers leasing a vehicle may consider Contract Hire GAP insurance.If a leased vehicle is written off or stolen and not recovered, the motor insurer’s settlement may not always cover everything due under the lease agreement.
Contract Hire GAP insurance is designed to help protect against eligible shortfalls, subject to the policy terms.
Can I get GAP insurance for a used car?
GAP insurance is not necessarily limited to brand new vehicles.Depending on the provider, policy type, age of the vehicle, purchase date, mileage and other eligibility criteria, cover may also be available for used vehicles.
Always check the eligibility requirements before purchasing a policy.
When should I buy GAP insurance?
The answer depends on the policy. Some types of GAP insurance have eligibility requirements relating to when the vehicle was purchased or delivered.
Rather than assuming you can purchase GAP insurance at any time, it is important to check the provider’s eligibility criteria and policy terms.
No. GAP insurance is generally an optional insurance product. Whether it is right for you will depend on your circumstances, how your vehicle was purchased or funded and how comfortable you would be with any potential financial shortfall following a total loss.
Is GAP insurance the same as comprehensive car insurance?
No. Comprehensive motor insurance and GAP insurance perform different roles.
Your comprehensive motor insurer is usually the first insurer involved following the theft or total loss of your vehicle and will generally assess its current market value.
GAP insurance is a separate product designed to provide additional protection against certain financial shortfalls, depending on the type of cover purchased.You would still need appropriate motor insurance for your vehicle.
What should I think about before buying GAP insurance?
Before choosing GAP insurance, it can be helpful to ask yourself:
- How did I buy the vehicle: cash, finance or lease?
- Is the vehicle new or used?
- What value would I want to protect if the car were written off?
- How quickly could my vehicle depreciate?
- Could I afford to cover a financial shortfall myself?
- What does my existing motor insurance already provide?
- Which type of GAP insurance is appropriate for my circumstances?
- What are the policy limits, exclusions and eligibility requirements?
If your vehicle is declared a total loss, you would normally make a claim through your comprehensive motor insurer first.
Your motor insurer will assess the vehicle and, where the claim is accepted, calculate the settlement according to the terms of your motor insurance policy.If you also have eligible GAP insurance, any GAP claim would then be considered in accordance with the type of cover you purchased and its policy terms.
How do I know which type of GAP insurance is right for me?
A good starting point is to look at how your vehicle was purchased. If you bought it outright or using finance, you may want to understand the differences between options such as Back to Invoice and Vehicle Replacement cover.
If your vehicle is leased, Contract Hire GAP insurance may be more relevant.The important thing is to understand what each policy is designed to protect rather than simply choosing a product because it is described as “GAP insurance”.
GAP insurance is designed to protect against certain financial shortfalls that can arise following the total loss of a vehicle.But not every driver, vehicle or finance arrangement is the same.
Understanding how your car was purchased, what your motor insurer is likely to cover and what value you want to protect can help you decide whether GAP insurance is appropriate and which type of cover may suit your circumstances.
Before purchasing any policy, always check the eligibility criteria, limits, exclusions and full policy wording.
