If someone else caused the accident, you are entitled to full recovery — including the reduction in your vehicle's market value that no repair can undo. This is your legal right, and most insurers won't mention it.
When your vehicle is repaired after a non-fault accident, most drivers assume the matter is settled. The repair bill is paid, the car looks right — job done. But there is a financial consequence that the repair process cannot address: the vehicle's accident history.
Once a vehicle has been in an accident, that fact is recorded — on HPI checks, on the V5, through insurers and dealers. When you come to sell or trade the vehicle, buyers will either walk away or significantly reduce their offer. This measurable reduction in resale value is known as diminution in value, and it is a recoverable financial loss.
UK case law — established in Payton v Brooks [1974] — is clear: the at-fault party must restore you to your pre-accident position. That includes the resale value your vehicle has lost. But insurers will not bring this up unless you do.
Payton v Brooks [1974] established that a non-fault claimant is entitled to claim the diminution in market value of their vehicle from the at-fault party's insurer. This is a well-established legal principle — but one that insurers rely on claimants not knowing about.
Applied to your vehicle's pre-accident market value. Calculated from live VRM data.
The other driver was at fault, pulled out, rear-ended you, or failed to give way. You have a right to full recovery — not just repair costs.
The repair is complete, or is underway. The value loss is calculated from the pre-accident value — the repair itself is evidence of the damage that occurred.
Generally applies to vehicles worth over £3,000–£5,000. Higher-value vehicles, newer models, and prestige brands see the largest value loss.
All road vehicles with a registerable resale value are eligible. Commercial vehicles, fleet cars, and personal vehicles all qualify.

Your loss is presented as a precise, professionally calculated number based on real market data — not an estimate you invented.
Legal basis they must address
The pack cites Payton v Brooks and the at-fault party's legal obligation to restore you to your pre-accident position. They can't ignore this.

Where an engineer's report is available, it becomes the formal basis for severity — removing the insurer's ability to dispute how serious the damage was.
