If your car is written off, your motor insurer only pays its current market value — which can be thousands less than you paid or still owe. This guide explains how GAP insurance fills that shortfall, the different policy types, and when it is worth buying.
When a car is written off or stolen and not recovered, your comprehensive motor insurer pays out the car's current market value at the time of loss — not what you paid for it or what you still owe on finance. Because cars depreciate quickly, especially in the first two to three years, this can leave a significant shortfall. GAP insurance is a separate policy that pays that difference, on top of your normal motor insurance payout.
Types of GAP Insurance
Return-to-invoice (RTI) — tops up the payout to match the original invoice price you paid for the car
Finance/shortfall GAP — tops up the payout to clear your outstanding finance settlement figure, useful if you are in negative equity on a PCP or HP deal
Vehicle replacement GAP — pays towards a brand new replacement of the same make and model, usually only available on cars under a certain age
Lease GAP — covers the shortfall between the payout and what is owed under a lease agreement
Where to Buy It
Dealerships offer GAP insurance at the point of sale, but it is often significantly cheaper from an independent GAP insurance specialist. FCA rules require dealers to give you a deferral period before you can be asked to buy, specifically to let you shop around rather than commit under time pressure in the finance office.
Exclusions to Check
Look carefully at mileage limits, maximum vehicle age and value at the start of the policy, whether commercial use such as ride-hailing or delivery driving is covered, and the fixed term of the policy (commonly 2–5 years). GAP insurance pays out only after your main motor insurer has settled the total loss claim, so the payout timeline runs in two stages rather than one combined process.
Is It Worth It?
GAP insurance tends to be most valuable on newer or higher-value cars bought with a small deposit, where negative equity in the early years is largest. It is less valuable on cheaper used cars or once you are several years into ownership and the gap between value and what you owe has narrowed. Weigh the premium against the size of the shortfall you would realistically face, and your own ability to absorb that cost from savings if the worst happened.
GAP (Guaranteed Asset Protection) insurance covers the difference between what your motor insurer pays out if your car is written off or stolen and never recovered, and either what you originally paid for the car or what you still owe on finance. Your motor insurer only pays the car's current market value at the time of the loss, which can be thousands less than what you paid or owe, especially in the first two to three years.
What is the difference between return-to-invoice and finance GAP insurance?
Return-to-invoice GAP pays the difference between the motor insurer's payout and the original invoice price you paid for the car. Finance GAP (sometimes called "shortfall" cover) pays the difference between the payout and your outstanding finance settlement figure, which matters most if you are on a PCP or HP agreement where negative equity is common in the early years.
Do I need GAP insurance if I own my car outright with no finance?
It can still be worthwhile if you would be unhappy receiving only the current market value and having to fund the difference to replace the car like-for-like, since cars depreciate fastest in the first few years. If you would be comfortable topping up the shortfall from savings, or you plan to keep the car for many years so the gap has narrowed, GAP insurance is less essential.

Can I buy GAP insurance from anyone other than the car dealer?
Yes, and it is usually cheaper to buy from an independent GAP insurance specialist rather than through the dealership at the point of sale, where premiums are often marked up significantly. The FCA requires dealers to give you a deferral period (commonly a few days) before you can be asked to decide, specifically so you have time to shop around.
How long does GAP insurance cover last?
Policies are typically sold for a fixed term, commonly 2 to 5 years, matching the period when the gap between market value and what you paid or owe is largest. Cover normally ends automatically once the term expires, regardless of how long you keep the car, so check the end date rather than assuming it renews.
Does GAP insurance pay out immediately after a write-off?
No — GAP insurance only pays out after your primary motor insurer has settled the total loss claim and confirmed the market value payout. The GAP insurer then tops up the difference, so there can be two separate claims processes running one after the other rather than a single combined payout.
Are there exclusions I should check before buying?
Common exclusions include cars used for hire or reward (such as ride-hailing or delivery use unless specifically covered), certain high-mileage limits, a maximum vehicle age or value at purchase, and situations where your primary motor insurer's payout is reduced due to non-disclosure or a modified vehicle. Always read the policy schedule for the specific vehicle-use and mileage limits.
Is GAP insurance regulated by the FCA?
Yes. GAP insurance is a regulated general insurance product, and dealers selling it alongside car finance must follow FCA rules including a mandatory information break before you commit, aimed at reducing high-pressure point-of-sale selling.
Is GAP insurance worth it on a low-value used car?
Generally less so, because the gap between market value and what you paid narrows quickly on cheaper cars, and the premium may not be proportionate to the potential shortfall. It is most commonly bought on newer or higher-value cars, or where a large finance deposit was not paid, making negative equity larger in the early ownership years.
