How motor claims are assessed
The insurer's motor engineer or assessor inspects the vehicle, sometimes only from photographs, and prepares an estimate of repair costs. If repairs exceed a share of the vehicle's pre-accident value, the vehicle may be declared an economic total loss and the insurer pays a market value, minus any excess and salvage value where applicable.
The two key numbers are therefore the repair estimate and the pre-accident value. Most disagreements concern one or the other.
Vehicles covered in this family
The guides below are organised by type of vehicle, as each segment has its own market and repair specifics.
- Private cars and general motor vehicle damage
- Motorcycles, scooters and other two-wheelers
- Motorhomes, campervans and caravans
- Commercial vans and trucks used for business
When the valuation feels too low
Write-off offers are often based on databases of average prices that may ignore low mileage, recent maintenance, options or regional demand. An independent assessor can compile comparable listings, review the condition reported and present a reasoned counter-valuation. For classic or modified vehicles, an agreed value in the policy usually carries more weight than market guides.
Repair disputes and hidden damage
Other conflicts arise over parts quality (original or alternative), the labour time allowed, safety systems recalibration, and damage discovered once the vehicle is dismantled. A supplementary inspection before repairs continue protects both sides.
Which guide to open
Start with the motor vehicle damage page for cars. Riders should go to the motorcycle guide, where safety gear and accessories are also discussed. Leisure vehicles have their own motorhome and caravan page, covering both the vehicle and the living area. Business vehicles, including loss of use for a company, are covered in the commercial trucks and vans guide. Each topic has a companion page on assessor fees.
Steps right after a vehicle loss
Photograph the scene and the damage, collect the other party's details and witness contacts, keep maintenance records and purchase invoices at hand, and do not dispose of the vehicle before the claim is settled or the insurer agrees.
Third-party claims and uninsured losses
When another driver is at fault, you may claim either from your own insurer or directly from the other party's insurer, depending on local rules and your cover. Beyond repairs, claims can include a replacement vehicle, loss of use, towing and storage, damaged personal belongings and diminished value for a newer car, although acceptance of that last item varies widely between countries.
Storage fees can grow quickly while a dispute drags on, so ask who is responsible for them and move the vehicle if the insurer agrees. Uninsured losses such as your excess or loss of no-claims discount may sometimes be recovered from the liable party. An independent assessor's report can support those claims as well as the main repair or total loss figure.
