GAP Insurance Guide UK: Do You Really Need It?
GAP insurance guide: Buying a car is a big financial commitment — whether it’s brand new or nearly new. But what many drivers don’t realise is that standard car insurance only pays out what your vehicle is worth at the time of a claim, not what you originally paid.
That’s where GAP insurance comes in.
This guide explains what GAP insurance is, how it works, and whether it’s worth considering.
What is GAP insurance?
GAP stands for Guaranteed Asset Protection. It’s designed to cover the “gap” between your insurer’s payout and either the original purchase price or the outstanding finance on your car.
If your vehicle is written off or stolen, your standard insurance policy typically pays the current market value. Because cars depreciate quickly, that amount can be significantly less than what you paid — especially in the first few years of ownership.
GAP insurance steps in to bridge that difference.
Why standard insurance often isn’t enough
Most comprehensive policies are based on market value, not replacement cost.
So if you bought a car for £20,000 and it’s written off a year later, your insurer might only pay £15,000. Without GAP insurance, you’d need to find the remaining £5,000 yourself — even worse if you’re still repaying finance.
Vehicle ownership and valuation data is linked through bodies such as the Driver and Vehicle Licensing Agency, which insurers use when calculating payouts, but depreciation is unavoidable.
Types of GAP insurance
There are several forms of GAP cover available in the UK, each suited to different situations.
Return to Invoice GAP
This covers the difference between your insurer’s payout and the original price you paid for the car.
It’s popular with buyers who want reassurance that they won’t lose money if their vehicle is written off early in ownership.
Finance GAP
Designed for drivers who purchased their car using finance or PCP, this type covers any shortfall between your insurance payout and the remaining balance on your agreement.
This can be crucial if you’d otherwise be left paying for a car you no longer have.
Vehicle Replacement GAP
Instead of paying back to the invoice value, this version tops up your insurer’s settlement so you can replace your car with a similar new model.
This is most common for brand-new vehicles.
Who should consider GAP insurance?
GAP insurance isn’t essential for everyone, but it’s worth considering if:
- You bought a new or nearly new car
- You’re using finance or PCP
- Your vehicle depreciates quickly
- You’d struggle to cover a large shortfall yourself
If you bought an older car outright, GAP insurance is usually less relevant.
How long does GAP insurance last?
Policies typically run for between one and five years. Coverage usually starts after your standard insurer settles a claim, not immediately after the incident.
It’s important to buy GAP insurance soon after purchasing your vehicle — many providers won’t offer it if too much time has passed.
Is GAP insurance expensive?
Costs vary depending on car value, policy length, and cover type, but GAP insurance is generally far cheaper when purchased independently rather than through a dealership.
Dealers often add significant markups, so shopping around can save a surprising amount.
Common misconceptions about GAP insurance
Many drivers assume their comprehensive policy already covers this — it doesn’t.
Others believe GAP insurance replaces standard insurance, but it only works alongside it. You still need a regular car insurance policy for GAP to apply.
And while GAP sounds complex, it simply acts as a financial safety net during a worst-case scenario.
