GAP Insurance vs RTI Cover UK 2026

Last reviewed: 26 April 2026

Understanding the three main GAP types

GAP (Guaranteed Asset Protection) insurance exists because Comprehensive motor insurance pays only the vehicle's current market value at the time of total loss, which is always less than the original purchase price due to depreciation, and may be less than any outstanding finance balance.

The three main GAP products address three different financial exposures:

Return to Invoice (RTI) GAP: Pays the difference between the Comprehensive insurance market-value settlement and the vehicle's original purchase invoice price. RTI is the oldest and most straightforward GAP structure. Where a vehicle purchased new for £28,000 is written off after two years when its market value is £18,000, RTI GAP pays the £10,000 difference to return the consumer to the original invoice position.

Finance GAP: Pays the difference between the Comprehensive insurance market-value settlement and the outstanding finance balance at the time of total loss. Where the two-year-old vehicle (market value £18,000) has an outstanding PCP or HP balance of £20,000, Finance GAP pays the £2,000 shortfall to clear the finance account, protecting the consumer from personal liability for the residual debt.

Vehicle Replacement Insurance (VRI): Pays the difference between the Comprehensive settlement and the cost of replacing the vehicle with an equivalent new model at the time of total loss. VRI covers the consumer's cost of returning to an equivalent new vehicle rather than just the invoice price of the specific vehicle lost.

When to choose RTI GAP

RTI GAP is appropriate where: the vehicle was purchased outright with cash (no finance obligation, the exposure is purely the depreciation gap between purchase price and current market value); or the vehicle was purchased on a hire-purchase arrangement where the consumer is steadily acquiring equity (the finance balance falls below the market value quickly on HP structures); or the vehicle is a high-value model where the original invoice price substantially exceeds the market value after two to three years.

RTI produces a useful recovery for cash buyers who want to ensure their insurance settlement restores them to their original financial position after depreciation. For a cash buyer who paid £35,000 for a luxury SUV now worth £22,000 after three years, RTI GAP pays the £13,000 depreciation difference.

RTI is less appropriate for PCP finance holders, because RTI pays to the invoice, not to the outstanding finance balance. In months 12 to 24 of a PCP agreement, the outstanding balance may exceed the invoice (where deposit plus payments have not yet reduced the balance below the original price net of deposit). For PCP holders, Finance GAP is the more relevant product type.

When to choose Finance GAP

Finance GAP is the essential product for PCP (Personal Contract Purchase) and HP (Hire Purchase) finance holders, specifically targeting the period when the outstanding finance balance exceeds the vehicle's current market value.

The Finance GAP calculation is based on the outstanding balance provided by the finance company at the total-loss settlement date. This figure includes all remaining payments, balloon payment (for PCP), and any early settlement charges. Finance GAP pays the specific shortfall between this balance and the insurance market value settlement.

As covered in the batch 23 and 24 GAP articles, the Finance GAP risk is highest in the early months of a PCP or HP agreement. Finance GAP is the correct product for this exposure.

When to choose VRI

Vehicle Replacement Insurance is appropriate where: the vehicle is in its first year of ownership (when depreciation is steepest and the like-for-like replacement cost most closely matches the original purchase price); or where the specific vehicle model has increased in market value since purchase (rare but occurs for limited editions or high-demand models); or where the consumer's primary objective is to return to an equivalent new vehicle rather than to recover the original invoice or clear finance.

VRI is typically the most expensive GAP product type because it covers the greatest potential financial exposure, the current new price of an equivalent model, which may have increased above the original purchase price due to manufacturer price rises.

FCA cooling-off and independent GAP sourcing

As confirmed in batches 23 and 24, dealer-sold GAP insurance is subject to a minimum two-working-day FCA deferral period at the point of sale, preventing same-day completion of GAP alongside the vehicle finance agreement. Independent GAP insurance from BIBA-registered specialist brokers (biba.org.uk/find-insurance/) typically provides equivalent or superior coverage at lower premiums than dealer-sold products.

Confirm FCA authorisation of any GAP provider at register.fca.org.uk before purchasing.

Key Figures

Stacking GAP with the motor Comprehensive policy

GAP insurance operates as a secondary layer above the standard Comprehensive motor insurance policy. The Comprehensive insurer pays the vehicle's current market value on total loss. The GAP insurer pays the additional amount to bring the total settlement to the RTI invoice price, the outstanding finance balance, or the replacement new-vehicle cost, depending on the product type.

This stacking arrangement means two separate insurers are involved in a total-loss settlement: the Comprehensive insurer handles the primary claim and pays the market value; the GAP insurer receives confirmation of the Comprehensive settlement and pays the GAP element separately. The policyholder may need to coordinate between the two insurers to ensure the full settlement is completed.

ABI guidance confirms that GAP insurance products must be clearly disclosed, the IPID for any GAP product provided through an FCA-authorised channel sets out the specific calculation methodology, claim process, and any conditions. Confirm the specific GAP product's IPID at quotation to understand exactly how the claim calculation works for the specific finance structure.

For cash buyers, RTI GAP provides the most straightforward settlement logic, the invoice price is a fixed, documented figure, and the gap is a simple arithmetic difference. For finance customers, the outstanding balance calculation involves interaction with the finance company, making Finance GAP slightly more complex at claims stage.

Frequently Asked Questions

What is the difference between RTI and Finance GAP?

RTI pays the gap between the insurance settlement and the original purchase invoice. Finance GAP pays the gap between the settlement and the outstanding finance balance. For PCP or HP finance holders, Finance GAP is typically the more relevant product because it specifically addresses the finance shortfall risk.

Which GAP insurance should I get for a PCP car?

Finance GAP is the most directly relevant for PCP finance, it pays the difference between the motor insurance settlement and the outstanding PCP balance, including the balloon payment component. RTI would pay to the invoice price, which may be less than the outstanding PCP balance in early months.

When is VRI the right choice?

VRI is most appropriate for drivers in their first year of ownership who want to ensure they can afford an equivalent new model after a total loss. It covers the highest potential exposure (new-model replacement cost) and is typically the most expensive GAP type.

Do cash buyers need GAP insurance?

Cash buyers have no finance obligation, but they may still face a significant depreciation gap between purchase price and current market value. RTI GAP addresses this specific exposure for cash buyers who want to recover the full original purchase price in the event of a total loss.

Is dealer-sold GAP always more expensive than independent?

FCA market studies have consistently found that dealer-sold GAP premiums exceed independently-distributed equivalents. The FCA's two-working-day deferral allows time to compare independent options before committing to the dealer-offered product.
