I would inform my insurance company and make a secondary claim against her insurance for uninsured losses, which would include any loss of no-claims or rises in your premium for the next x years.
As it wasn't your fault this should be dealt with at zero cost to you - this should include your own premium, moving forward from this point.
Gone but not forgotten:
