A like-for-like replacement vehicle is normally provided for as long as your own car is being repaired, or until your claim reaches a resolution — for example, if your vehicle is written off rather than repaired.
Repair times vary depending on the extent of the damage, parts availability, and the repairer's workload, so your Claims Advisor will keep you updated on realistic timescales as the claim progresses.
If your vehicle is declared a total loss, your replacement vehicle typically continues until a settlement is agreed and you've had a reasonable opportunity to source a new car.
