Guaranteed Asset Protection (GAP) insurance covers the financial shortfall between a standard motor insurance payout and the original price of a vehicle. When a car is written off or stolen, motor insurance providers pay the current market value at the time of the claim. That figure is usually lower than what the driver originally paid, due to depreciation.
This glossary covers what GAP insurance is, the main types available in the UK, and how to choose the right level of cover.
GAP insurance for cars, also called insurance gap cover or shortfall insurance, is a supplementary motor insurance product. It covers the financial shortfall between what a standard motor insurer pays out after a total loss and what the driver originally paid or still owes.
Standard motor insurance pays the market value of the vehicle at the time of the claim. Because cars depreciate quickly, that figure is often thousands of pounds below the original purchase price or outstanding finance balance.
GAP insurance coverage is not a legal requirement in the UK. Standard motor insurance only pays the market value of the car at the time of the loss. That figure drops steeply in the first few years of ownership.
Drivers who bought their car on finance, Personal Contract Purchase (PCP), or a lease are particularly exposed, as their outstanding balance often exceeds the insurer's payout. GAP insurance steps in to cover that difference.
GAP insurance is not one-size-fits-all. There are several types of GAP insurance coverage, each designed to work best in specific situations, depending on whether the driver bought the car outright, on finance, or on a lease. These are the five main types available in the UK. Each one protects against a different kind of financial shortfall after a total loss:
RTI GAP insurance is one of the most common forms of vehicle GAP insurance in the UK. Return to invoice cover pays the difference between the car insurance provider's total loss payment and the exact price paid for the car when it was first purchased. RTI is best for new and nearly-new cars bought outright, on hire purchase, or on PCP.
If a vehicle is written off or stolen and the motor insurer pays only the market value, this policy pays the difference between that and the original invoice price. It does not matter how much is still owed on finance; RTI pays based on what was paid, not what is still owed.
For example: a driver buys a new car worth £25,000. The insurer pays out £15,000 after a total loss. RTI GAP insurance would then pay out the £10,000 difference.
This is a comprehensive form of GAP insurance for new cars. It covers the difference between the insurer's payout and the cost of an equivalent replacement vehicle at the time of the claim. If the driver originally bought a brand-new car, the equivalent replacement will be based on the brand-new version at the time of the claim. Vehicle Replacement GAP also considers inflation, spec changes, and discontinued models.
If the car has gone up in price since it was bought, this policy aims to cover that. It is typically more expensive than RTI, but it offers the highest potential payout. VRI is available for brand-new cars within 90 days of first registration.
If a car is declared a total loss, the policy will increase the insurer's total loss valuation of the vehicle to whichever is highest of these amounts:
Finance GAP is the most basic form of GAP insurance for financed cars. It covers the shortfall between the insurance payout and the finance balance at the point of write-off. This type of GAP does not return the cost of the original purchase price. Instead, it pays just enough to settle outstanding finance payments if the car is written off.
It is useful for drivers mainly concerned about being left with debt. The policy does not provide any financial assistance to help replace the car.
Finance GAP is most common with PCP and hire purchase agreements. Finance GAP insurance covers any shortfall between the insurer's payout and the outstanding balance on a finance agreement. It is designed to settle finance agreements, not fund a replacement vehicle. It usually more affordable, but that reflects its more limited scope.
GAP insurance for leased cars and GAP insurance on a lease cover drivers who do not own the vehicle they drive. If the car is written off or stolen, Contract hire GAP clears the outstanding balance on the lease agreement rather than paying the driver directly.
GAP insurance on PCP differs from lease GAP because PCP drivers have the option to buy the car at the end of the agreement, while lease drivers simply return it. Contract hire and lease GAP covers up to £15,000 towards the outstanding balance, including:
Personal contract hire cover remains a popular option in the UK, with the total leased vehicle fleet standing at nearly 1.9 million vehicles, according to BVRLA data.
If a leased car is involved in an accident, stolen, or written off, the driver remains liable for outstanding repayments. Without GAP insurance coverage, that liability can be significant in the first few years of the agreement, when depreciation is at its steepest.
Agreed Value GAP is often used by drivers who bought a car privately, from outside the dealer network, or after the standard GAP eligibility window has passed.
An agreed value GAP policy is based on a starting value agreed when the cover is taken out, not what was originally paid for the car. That makes it useful for drivers who bought a car second-hand, from a private seller, or outside the usual GAP insurance eligibility window, such as more than 180 days after purchase.
The agreed value is usually based on the Glass' Guide Retail Value at the time the policy is bought. This type of cover is available through providers such as ALA GAP insurance and Total Loss GAP insurance.
GAP insurance tops up a total loss payout from a standard motor policy when a vehicle is written off or stolen. It covers some or all of the "gap" between the motor insurer's market‑value settlement and the original invoice price or the outstanding finance or lease balance.
For GAP insurance on used car, the mechanism is the same. The key difference is that the insurer uses the used vehicle's purchase price, not a new list price, when calculating the gap. Some policies also cap the vehicle age or mileage at the start of cover.
GAP insurance for motorcycles works on the same principle, but fewer insurers offer it and underwriting criteria are often tighter. Cover still bridges the shortfall between what the bike insurer pays, and the amount originally paid or owed on finance.
Standalone GAP insurance providers that sell online usually charge lower premiums than dealers because their commission and overheads are lower. The basic claims process is similar across providers. The main motor insurer settles first. Then, the GAP insurer calculates and pays the top‑up to the finance company, lease company, or policyholder, depending on the cover terms.
The cost of GAP insurance depends on the vehicle value, term, type of GAP (finance, return‑to‑invoice, or lease), and distribution channel. Dealer‑sold policies have historically been more expensive, partly because a high share of the premium was paid out as commission. This was one of the concerns raised by the FCA in 2023–2024.
In the UK, the sale of GAP insurance is regulated under the wider financial‑services framework, with several bodies involved:
This is the lead regulator for the distribution and conduct of GAP insurance. Any firm arranging or advising on GAP must be authorised or an appointed representative under the FCA regime.
The FCA also writes product‑specific rules in its Insurance: Conduct of Business Sourcebook (ICOBS).
These include the deferred opt‑in rule for GAP contracts, which stops dealers from completing a GAP sale at the same time as the vehicle sale. It also forces a waiting period so customers can consider alternatives.
In February 2024, the FCA asked most GAP insurers to pause new sales after finding poor value and very high commissions. Sales were allowed to resume once changes were made.
Part of the Bank of England, the PRA supervises the financial soundness of insurers that underwrite GAP policies, ensuring they hold enough capital and manage risk properly.
The FOS handles unresolved consumer complaints about GAP sales or claims handling. Policy terms from GAP firms routinely direct customers with disputes to the FOS.
The FSCS compensates eligible policyholders if a regulated GAP insurer or intermediary fails and cannot meet valid claims. This sits alongside the FCA and PRA regime as the UK's statutory last‑resort scheme.
Together, these bodies oversee product design, pricing fairness, sales practices and consumer protection for GAP insurance in the UK market.
You can assist your clients in finding the most suitable GAP cover by following this process:
Step 1. Confirm regulatory permissions: Secure FCA insurance‑distribution permission for general insurance or become an appointed representative of an authorised principal before arranging GAP insurance
Step 2. Select specialist GAP manufacturers: Partner up with specialist GAP insurers or MGAs that have resumed sales after the FCA's 2024 fair‑value intervention and can evidence Consumer Duty compliance and reduced commissions
Step 3. Build compliant product journeys: GAP is sold as an optional add‑on with its own documents and clear pricing. The sales journey applies the ICOBS deferral‑period rules and gives all prescribed pre‑contract information (price, benefits, key exclusions, duration, and that the policy is optional)
Step 4. Align pricing and commission with fair value: The broker and insurer agree on premiums, benefits and commission levels that deliver fair value, monitoring loss ratios, claims outcomes and cancellation patterns. These must also align with the Consumer Duty and the FCA's general‑insurance distribution guidance
Step 5. Target only the right customers: Ensure that sales staff are trained to recommend GAP only where a clear shortfall risk exists (e.g., cars with high finance, long terms, or rapid depreciation). This is to ensure consistency with product‑governance expectations and the documented target market
Step 6. Embed robust scripts, training, and records: Use standard scripts and online flows that explain what GAP does, confirm it is optional, and avoid pressure selling. Systems record when information was given and when the contract was concluded, proving compliance with GAP‑specific rules
Step 7. Set up complaints and redress routes: Make sure to have clear processes to handle GAP complaints, with signposting to the Financial Ombudsman Service and, if needed, FSCS protection. These are required in the FCA's broader distribution‑chain and conduct rules
