TL;DR - KEY POINTS
- GAP insurance pays the difference between your insurer's settlement and the amount you originally paid or owe on finance - standard car insurance only pays current market value.
- It is most relevant in the first three years of ownership when new cars depreciate fastest - a new car can lose 40% of its value in year one.
- Three main types: Return to Invoice (RTI), Vehicle Replacement (VRG), and Finance GAP - the right type depends on whether you bought outright or on PCP/HP.
- GAP insurance is not compulsory and is not included in standard comprehensive policies - it must be purchased separately.
- Standalone GAP insurance from specialist providers is typically 50-70% cheaper than GAP sold at the dealership at the point of purchase.
UK CAR INSURANCE - GAP COVER - 2026
KEY FACTS
- GAP insurance covers the shortfall between your car's insured value and what you paid.
- Dealership GAP is the most expensive route - compare standalone providers first.
- FCA regulated - any GAP insurance provider in the UK must be FCA authorised.
- Most useful for new cars, cars on PCP/HP finance, and high-depreciation models.
- The FCA introduced a 2-day deferral rule in 2015 - dealers cannot sell GAP at the same time as the vehicle.
When your car is written off or stolen, your comprehensive insurer pays the current market value - not what you paid for it. For a new car, that difference can be several thousand pounds, particularly in the first year when depreciation is steepest. GAP insurance exists to cover that shortfall.
This guide explains what GAP insurance is, the different types available in the UK, how much it costs, and when it is and is not worth buying.
What GAP insurance covers
If your car is declared a total loss - either written off after an accident or stolen and not recovered - your comprehensive car insurer will pay the vehicle's current market value at the time of the claim. This is based on published trade guides such as Glass's or CAP, adjusted for the vehicle's condition, mileage, and specification.
The problem is that new cars depreciate quickly. A car worth PS25,000 when new may be valued at PS16,000 by a car insurer after two years. If you paid PS25,000 (or still owe PS20,000 on a finance agreement), you face a gap of PS4,000 to PS9,000 that your main insurance will not cover.
GAP insurance covers that difference. Depending on the policy type, it pays either the difference between the insurer's settlement and the original invoice price, the difference between the settlement and the cost of an equivalent replacement vehicle, or the outstanding finance balance above the settlement.
The three main types of GAP insurance
Return to Invoice (RTI): pays the difference between your car insurer's settlement and the original purchase price shown on the invoice. This is the most common type and is suitable for cars bought outright or on finance. If you paid PS22,000 and the insurer settles at PS15,000, RTI pays PS7,000.
Vehicle Replacement GAP (VRG): pays the difference between the insurer's settlement and the cost of purchasing a brand new equivalent replacement vehicle at the time of the claim. This accounts for any price increases since you bought your car and is the most comprehensive type, but is also the most expensive.
Finance GAP: pays the difference between the insurer's settlement and the outstanding balance on a PCP or HP finance agreement. This ensures you do not end up still owing money on a car that no longer exists. It does not top up to the original invoice price - it only covers the finance shortfall. Often the minimum viable option for cars on PCP where the outstanding balance exceeds the market value.
Some policies combine RTI and finance elements. Always check the policy wording to confirm which shortfall is covered and whether any cap applies to the maximum payout.
Who needs GAP insurance
New cars in the first three years: new cars typically depreciate 15-35% in the first year and 40-60% over three years. The gap between market value and original purchase price is largest during this period. Anyone buying a new car outright should at minimum compare GAP insurance quotes.
Cars on PCP or HP finance: finance agreements spread the cost of a depreciating asset. In the early months of a PCP deal the outstanding balance can exceed the car's market value - this is sometimes called being in negative equity on the car. If the car is written off during this period, the insurer's settlement will not clear the finance balance. Finance GAP or RTI GAP is strongly relevant here.
High-depreciation models: some cars depreciate significantly faster than average - certain executive and prestige models, cars with high initial list prices, and electric vehicles with high battery costs. For these vehicles the cash difference between purchase price and market value can be large even after two or three years.
Who is unlikely to need it: buyers of older used cars where the gap between market value and purchase price is small; anyone who paid significantly below market value for their car; and anyone who can absorb the depreciation shortfall without financial hardship.
How much GAP insurance costs
Standalone GAP insurance from specialist UK providers typically costs PS100 to PS300 for a three-year policy, depending on the vehicle value, type of GAP cover, and the excess on your main policy. Policies can cover vehicles up to PS75,000 or more at the higher end.
Dealership GAP insurance is substantially more expensive - typically PS300 to PS600 or more for equivalent cover - because dealerships earn a significant commission on the sale. The FCA introduced a mandatory two-day deferral rule in 2015 specifically to prevent dealers from pressure-selling GAP at the point of vehicle purchase: a dealer who mentions GAP insurance during the vehicle sale must wait at least two days before completing the GAP sale, giving the buyer time to compare alternatives.
Standalone specialist providers include names such as ALA, MotorEasy, and GapInsurance.co.uk among others. Comparison through a broker typically produces lower prices than going direct to a single provider.
What GAP insurance does not cover
GAP insurance only pays out when your main insurer has already settled a total loss claim. It does not cover partial damage, mechanical breakdown, maintenance, or theft of contents. It does not pay if your main insurer voids your policy or rejects the claim - GAP is secondary cover that depends on the primary claim being settled.
Most GAP policies have exclusions for vehicles used for hire and reward, racing, and commercial use beyond standard commuting. Check the policy terms against your actual usage before purchasing.
GAP policies also typically have a maximum age and mileage limit for the vehicle at the time of purchase, and a maximum vehicle value. Verify the vehicle qualifies under these limits before buying.
FCA regulation and your rights
All GAP insurance providers in the UK must be authorised and regulated by the Financial Conduct Authority (FCA). You can check any provider's status on the FCA Register at register.fca.org.uk before purchasing.
The FCA introduced significant reforms to GAP insurance in 2015 following concerns about poor value and high distributor commissions. The two-day deferral rule for dealer sales and requirements to provide clear price comparisons were introduced as a result. The FCA conducted a further review in 2023-24, resulting in temporary suspension of dealership GAP sales by major providers in early 2024 while value improvements were agreed.
If you have a complaint about a GAP insurance provider, you can escalate to the Financial Ombudsman Service (FOS) after exhausting the provider's own complaints process.
GAP insurance for electric vehicles
Electric vehicles present a particular case for GAP insurance. Battery degradation is a known factor in EV valuation - insurers price EVs lower than equivalent petrol cars partly because battery replacement costs are high and the used EV market is still maturing. This means the gap between purchase price and insurer settlement can be larger for EVs than for comparable internal combustion engine cars.
New EVs have been subject to significant list price reductions by manufacturers in recent years, which affects the Vehicle Replacement GAP calculation - if the manufacturer reduces the list price after you buy, VRG pays to the new lower list price, not what you paid. RTI policies are therefore often preferable for EVs as they are anchored to the actual invoice price.
Check whether a GAP policy you are considering explicitly covers electric vehicles and whether any battery-related exclusions apply. Some older GAP policies pre-date the mass market EV era and may have ambiguous wording on battery coverage.
How to compare GAP insurance quotes in the UK
The key variables when comparing GAP insurance are: policy type (RTI, VRG, or Finance GAP); the maximum claim limit (some policies cap payouts at PS15,000 or PS20,000 regardless of the actual shortfall); policy duration (one, two, or three years is typical); and the excess on your main car insurance policy (some GAP policies contribute toward or waive this).
Standalone specialist GAP providers can be compared through brokers and aggregators. The price difference between the cheapest and most expensive equivalent policies is often PS100 to PS200 - substantial on a product that may cost PS150 total. Read the policy summary document (the Insurance Product Information Document, or IPID) for each quote before deciding - the headline price does not capture differences in maximum payout limits or exclusions.
The FCA requires all GAP insurance providers to give you a standardised IPID and a 30-day cooling off period. If you cancel within 30 days of purchase and before any claim, you are entitled to a full refund.
Is GAP insurance worth it for a used car?
For used cars, GAP insurance is less commonly worthwhile because the gap between purchase price and market value is smaller - used cars have already absorbed the steepest depreciation. It may still be relevant if you paid a premium price for a nearly-new car or if you are financing a used car on PCP where the outstanding balance could exceed market value.
Can I buy GAP insurance after I have already bought the car?
Yes. Most standalone GAP insurance providers will cover vehicles up to a certain age (typically three to five years old) regardless of when the car was purchased. Some require purchase within 180 days of buying the vehicle. Check the specific terms of each provider.
Does comprehensive car insurance include GAP cover?
No. Standard comprehensive car insurance pays the market value of the vehicle at the time of the claim. GAP insurance is a separate product that covers the shortfall between market value and original purchase price or outstanding finance.
What happens to my GAP insurance if I sell the car?
Most GAP policies are not transferable to a new owner. If you sell the car before the policy expires you can usually cancel and receive a pro-rata refund of the unused premium, subject to the provider's cancellation terms.
Is GAP insurance the same as new car replacement cover?
No. New car replacement cover is an optional add-on offered by some main car insurers that provides a brand new replacement vehicle if the car is written off within the first year (terms vary by insurer). GAP insurance is a separate standalone product with different coverage terms and a wider range of scenarios.
