I hate to say from recent experience, even when the accidents not your fault, you still get knobbed over. My car was parked at the side of the road, me inside watching tv, driver convicted at court due to the severity and I'm still suffering.
I can no longer get insured on my dads mk6, well not for less than £800 extra on his policy. My insurance went up £200.
My insurers LV, also took the excess, this will always happen and then it's claimed back from the other insurer. Get your legal cover solicitors involved.
I did get my full no claims, and a good value for my car.
But LV would not tell me the total value of the claim. I bet it was thousands they charged back.
