What Is Gap Insurance?
Gap insurance covers the difference between what your car insurer pays out after a total loss and what you originally paid for the vehicle or what you still owe on finance. Without it, you could be left thousands of pounds short.
Standard car insurance pays out the market value of your car at the time of the claim. A car worth £20,000 new might be valued at £14,000 after just one year.
If you still owe £18,000 on finance, your insurer’s payout leaves a £4,000 shortfall. Gap insurance closes that gap.
Your insurer pays market value, not what you paid or what you owe. After one year, that gap can be thousands of pounds. Gap insurance covers the shortfall, and buying online costs £100 to £400 for two to three years, roughly half what dealers charge.
Buy gap insurance separately when you compare car insurance quotes rather than accepting the dealer’s price.
How does gap insurance work?
Gap insurance pays out after your standard car insurer has settled a total loss claim. Your car insurer pays the current market value, and your gap insurer covers the shortfall.
The claims process step by step
First, your car must be written off or stolen and not recovered. Your main insurer declares it a total loss and pays the market value.
You then submit a claim to your gap insurer with proof of the original purchase price or outstanding finance balance. The gap insurer pays the difference.
What gap insurance doesn’t cover
Gap insurance only triggers on total loss claims. Your main fully comprehensive policy handles repairs, partial damage, and mechanical breakdowns.
If your main insurer rejects a claim, the gap insurer will too. Both policies must be valid for a gap payout to happen.
What are the different types of gap insurance?
There are three main types: return to invoice (RTI), vehicle replacement, and finance gap. Each covers a different shortfall, and the right one depends on how you bought the car.
| Type | What it covers | Best for |
| Return to invoice (RTI) | Difference between market value payout and the original invoice price | Cash buyers or anyone who paid more than the car is now worth |
| Vehicle replacement | Difference between market value payout and the cost of an equivalent new replacement | Owners of nearly new cars who want to replace like-for-like |
| Finance gap | Difference between market value payout and the outstanding finance balance | PCP, HP, or lease customers who owe more than the car is worth |
Which type should you choose?
If you bought on finance, finance gap is usually the right choice. It clears the loan so you’re not paying for a car you no longer have.
If you paid cash, RTI gets you back to what you spent. Vehicle replacement is the most generous but also the most expensive.

How does depreciation create the gap?
New cars lose value fastest in the first three years. A typical new car loses 15% to 35% in year one, a further 15% to 20% in year two, and 10% to 15% in year three.
Value vs finance balance over time
| Year | Typical car value | Typical finance balance | Gap |
| Purchase | £25,000 | £25,000 | £0 |
| Year 1 | £17,500 (−30%) | £21,000 | £3,500 |
| Year 2 | £14,000 (−44%) | £17,000 | £3,000 |
| Year 3 | £11,500 (−54%) | £13,000 | £1,500 |
| Year 4 | £9,500 (−62%) | £9,000 | £0 (crossed) |
In the early months, the car’s value drops faster than your payments reduce the balance. This creates negative equity.
By year three or four, the two lines usually cross. Your remaining balance drops below market value, and the need for gap cover fades.
How much does gap insurance cost?
Gap insurance typically costs between £100 and £400 as a one-off payment for two to three years of cover when bought from a specialist online provider. Dealer-sold policies can cost two to three times more.
Where the price difference comes from
Dealers sell gap insurance at the point of sale alongside the finance agreement. The FCA has highlighted that dealer-sold add-ons are often poor value.
Buying from a specialist provider online typically saves 50% to 60% compared to dealer prices.
The 14-day cooling-off rule
Since September 2015, FCA rules on add-on insurance require dealers to give you a cooling-off period. You can cancel dealer-sold gap insurance and buy cheaper cover elsewhere.
| Where you buy | Typical cost (one-off) | Notes |
| Specialist online provider | £100–£200 | Best value; FCA-regulated; covers 2–3 years |
| Car insurer add-on | £150–£300 | Convenient but less competitive on price |
| Dealer at point of sale | £300–£600+ | Most expensive; use the cooling-off period |

When do you need gap insurance?
You need gap insurance if you owe more on your car than it’s currently worth. This is most common in the first two to three years of ownership, especially with new cars on finance.
When it makes sense
Gap cover makes sense if you bought a new car on PCP, HP, or lease with a small deposit. A young driver buying their first car on finance is a typical example.
Finance terms longer than three years also increase the risk. The gap between value and balance takes longer to close.
When you probably don’t need it
If you own the car outright with no finance, there’s no loan balance to worry about. The same applies if your car is older and has already been through its steepest depreciation.
If your remaining finance balance is already less than the car’s market value, there’s no gap to insure.
What isn’t covered by gap insurance?
Gap insurance only pays out on total loss claims approved by your main insurer. It doesn’t cover repairs, partial damage, mechanical failure, or claims your main insurer rejects.
Common exclusions
Wear and tear isn’t an insurable event. Undeclared modifications that contributed to the loss can void the claim too.
Personal belongings inside the car aren’t covered by gap insurance or standard car insurance. You’d need separate contents cover for those.
Negative equity on part-exchange
If you part-exchange a car and roll negative equity into a new finance agreement, gap insurance doesn’t cover that rolled-over balance. The government’s guidance on buying a car covers your consumer rights when trading in.
Your excess on the main policy is also deducted from the total loss payout before the gap insurer calculates their share.
Frequently Asked Questions (FAQs)
No, it’s entirely optional. Your finance company may recommend it, but they can’t require you to buy it from them.
Yes, but most providers require you to buy within 180 days to one year of purchase. The sooner you buy, the wider the gap you’re covering.
Once your main insurer has settled the total loss claim, the gap insurer typically pays within two to four weeks.
No, gap insurance only covers total loss situations. Negative equity rolled into a new finance deal isn’t covered.
You can usually cancel for a pro-rata refund. Some providers let you transfer the policy to a new vehicle instead.
It depends on the finance balance. If you owe more than the car is worth, gap cover protects that shortfall.
Yes, provided your main insurer declares it a total loss. Theft with non-recovery counts as a total loss, which triggers the gap policy.
