16. salvage of the "written-off" vehicle and contents
Once the policyholder accepts payment of the full market value, the insurer becomes the owner of the salvage. If the policyholder asks to keep the salvage, the insurer is entitled to deduct what it would have been able to sell the salvage for. This is usually not very much.
But what if the policyholder complains that the insurer (or its agent) disposed of the salvage before paying the full market-value? At this stage, the vehicle still belongs to the policyholder, and we take the view that the insurer should not have disposed of it without first obtaining the policyholder’s consent to the settlement of the claim – even if the insurer said it was only acting in the public interest by keeping a badly-damaged vehicle off the roads. In such circumstances, and unless the insurer returns the salvage, we usually award the policyholder compensation for inconvenience.
If the policyholder had personal belongings in the vehicle when the insurer disposed of it without consent, we are likely to award the cost of replacing these – usually on a like-for-like (rather than a new-for-old) basis.
"Written-off" vehicles are categorised – according to the severity of the damage – under a voluntary code agreed between the Association of British Insurers (ABI) and salvage dealers (ABI Code of Practice for the Disposal of Motor Vehicle Salvage):
- Category A vehicles are to be kept off the road and crushed.
- Category B vehicles are also to be kept off the road, but could be broken up for spare parts.
- Category C vehicles are repairable, but uneconomical to repair.
- Category D vehicles are repairable economically, but written-off for some other reason.
Since 7 April 2003 all category A, B and C vehicles notified to DVLA must pass a Vehicle Identity Check before they can be returned to the road. This is an identity check, to confirm that the vehicle is the original one and not stolen, and does not check roadworthiness or repairs.
