If your car is written off or stolen, your motor insurer pays its current market value, which can be thousands of pounds less than what you still owe on finance or paid new. GAP insurance covers that shortfall. Dealer-sold GAP policies commonly cost £200-£500 for cover over 2-3 years, while independent GAP specialists often charge £20-£60 a year for equivalent or better cover.

Why there's a 'gap' at all
New cars depreciate fastest in their first year — often 15-35% — and motor insurers only ever pay the car's current market value if it's written off or stolen, not what you paid or what you still owe on finance. If you financed most of the purchase price, that gap between the insurance payout and your outstanding finance balance can easily run into several thousand pounds, especially in years one and two of a new PCP or HP agreement.
The main types of GAP cover
- Finance GAP: pays the difference between your insurer's payout and your outstanding finance balance — most relevant if you're on PCP or HP.
- Return to Invoice (RTI) GAP: pays the difference between the payout and the price you originally paid for the car — useful if you bought outright or on a personal loan.
- Vehicle Replacement GAP: pays toward a brand-new equivalent replacement car, typically the most comprehensive and expensive option, and usually only available in the car's first year or two.
Dealer GAP vs independent GAP
Dealers often offer GAP insurance at the point of sale for convenience, but it's frequently the most expensive way to buy it — commonly £200-£500 for cover lasting 2-3 years. Independent GAP specialists selling the same type of policy typically charge a fraction of that, often £20-£60 a year, for comparable or better terms. You can buy GAP insurance from an independent provider up to a set period (commonly around 90 days) after buying the car, so there's no need to decide on the spot at the dealership.
When GAP insurance is worth it — and when it isn't
- Worth considering: new or nearly-new car, financed with a large loan or small deposit, high mileage driver, or in an area with higher theft rates.
- Less necessary: older or lower-value car, large deposit or no finance, or if your existing insurer already offers 'new car replacement' cover for a set period.
- Check whether your car insurance policy already includes some new-for-old or depreciation protection before paying twice for overlapping cover.
- Re-check the need for GAP each renewal — as the loan balance falls and the car's value stabilises, the gap narrows and cover may no longer be worthwhile.
Read the policy's exclusions carefully — most GAP policies won't pay out if your main motor insurance claim is refused (for example, due to undisclosed modifications or being underinsured), and many cap the total payout amount.
