Isow you should be able to claim against the local council for the damage caused.
They are responsible for keeping the roads safe.
A few years back my car (Porsche) was damaged due to a pothole, I did some research and found via my local councils website they are insured and legally you have a right to claim. I followed their claims procedure, basically sent photographs of the pothole, time and location with a repair estimate from Porsche. They paid out..
