Hi, I’ve been in a no-fault accident recently. The other party gave their details etc and owned up. Insurers have been notified and my car is waiting to be collected for repairs. I got a call from the other insurers saying they can arrange for repairs with a 5yr warranty and will provide a courtesy car. I told them my insurer is already arranging this, but they say it’s quicker and easier to go with them. Is this normal? What’s the best thing to do?
