GAP insurance cost UK 2026

Direct answer

How much does GAP insurance cost in the UK in 2026?

Buy it yourself from a specialist and GAP insurance costs roughly £107 to £205 for three years on a mainstream car with a £15,000 maximum claim limit. That is the full spread of the eight like-for-like quotes in Auto Express’s 2026 test — every quote for the same vehicle, the same return-to-invoice cover, the same claim limit and the same term. The RAC puts the wider market range at £100 to £300 for three years, which is consistent once bigger, dearer cars and broader cover types are included.

Three things move the price legitimately. The value of the car sets the size of the potential shortfall, so a £45,000 SUV costs more to cover than a £15,000 hatchback. The type of GAP matters next: return-to-invoice is the cheapest common form, while vehicle-replacement cover — which pays for a brand-new equivalent at tomorrow’s prices — sits at the top. And the term matters: most policies run two to four years, and the FCA’s own analysis put the average GAP contract at 36 months.

The fourth factor is the one buyers control least, and it is the reason the same policy can double in price: the sales channel. Insurance Premium Tax is charged at the standard 12% on a policy you arrange yourself, but HMRC applies the higher 20% rate to certain insurance sold alongside a motor vehicle. Eight extra points of tax land on the dealership version before a penny of commission is added — and the FCA found some sellers were taking up to 70% of the premium as commission. If you are budgeting for a car overall, our UK car running costs hub sets GAP alongside servicing, repairs and warranty.

What you are buying

What GAP insurance actually covers — RTI, finance GAP and vehicle replacement

GAP exists because of a mismatch. If your car is stolen or written off, your motor insurer settles at the vehicle’s market value on the day of the loss — not the price on your invoice and not the balance on your finance agreement. The Association of British Insurers is explicit that a total-loss settlement reflects what a comparable car would cost to buy at that moment. With the average motor claim payout at £4,900 in Q2 2026 and insurers paying out a record £3.2 billion in the quarter, most claims never reach that question — but a total loss does, immediately.

The shortfall is a depreciation problem. The RAC puts first-year depreciation at 15% to 35% and three-year depreciation at up to 50% or more, and the spread between models is enormous: our own analysis of electric car depreciation in 2026 found three-year retained values running from 29.4% to 61.8% of list price. A car that keeps 60% of its value creates a far smaller gap than one that keeps 30%.

The cover comes in distinct forms, and they are not interchangeable:

• Return to invoice (RTI) — tops the insurer’s settlement back up to the price you actually paid. The most common and usually the cheapest form.
• Return to value — the same idea, but benchmarked to the car’s market value when you bought it rather than the invoice. Relevant if you bought below book.
• Finance GAP — clears the outstanding balance on the agreement instead of restoring the purchase price. It typically excludes negative equity rolled in from a previous car.
• Negative equity GAP — extends finance GAP to include that carried-over debt.
• Lease / contract-hire GAP — settles the rest of the contract and the early-termination charges triggered by a total loss.
• Vehicle replacement (VRI) — the widest and dearest: it pays what an equivalent brand-new car costs on the day of the claim, which on a model whose list price has risen can exceed your original invoice.

One practical point before any of this matters: check what your motor policy already does. Many comprehensive policies include new-car replacement if the car is written off within the first 12 months and under a mileage cap, which duplicates part of what RTI cover does in year one. You can benchmark what you are already paying against the national picture in our UK car insurance cost index.

Who it suits

When GAP makes sense, when it does not, and the rules that protect you

This is a decision about exposure, not about the product being good or bad. The question is simple: if your car were written off tomorrow, how big would the shortfall be, and could you absorb it?

The gap tends to be largest for a new or nearly-new car bought on finance with a small deposit; for a model with steep depreciation; for a PCP or lease where the early-years balance falls more slowly than the value does; and where negative equity from a previous car has been rolled into the agreement. Scale matters here — Finance & Leasing Association members funded close to 88% of private new car purchases in the year to March 2026, so most new-car buyers are in the finance category by default.

The gap tends to be small or nil where you paid cash and could replace the car from savings; where the car is several years old and past the steepest part of the depreciation curve; where you bought well below invoice, so market value already tracks what you paid; where your motor policy already includes new-car replacement in year one; or where the outstanding finance is already below the car’s value. Buying GAP in those situations is buying cover for a shortfall that will not arise.

Two FCA rules exist specifically to give you room to make that judgement:

• The two-clear-day deferral (ICOBS 6A.1, in force since 1 September 2015). A dealer must first give you prescribed information in a durable medium — the total GAP premium shown separately from everything else, the significant features, the significant or unusual exclusions, the fact the cover is available from other providers and the date the clock started — and then cannot conclude the sale for two clear days. You may initiate the purchase yourself from the day after you receive that information, but the dealer cannot press you to.
• The 14-day cancellation right (ICOBS 7.1). A general insurance contract carries a 14-day cooling-off period, running from the day the contract is concluded or the day you receive the terms, whichever is later. Cancel inside it and you should get your money back, less the cost of any cover already provided. Beyond it, most GAP policies allow cancellation for a pro-rata refund of the unused term — but that is a matter of the individual policy wording, so read it before you sign.

Timing is finite: the RAC notes GAP is generally only available within the first 12 months of buying the vehicle, so “decide later” has an expiry date. If you do compare, compare like with like — the same cover type, the same claim limit, the same term and the same excess contribution — because as the table above shows, that is the only way the prices mean anything. And if a total loss does happen, remember your no-claims discount is a separate question: our guide to how no claims bonus works in 2026 explains what a write-off does to it.
