A van hit my car while stationary recently. An independent witness saw the incident and gave me the van's licence plate. The van's telematics show that it was on the street on which my car was parked at the time of the incident.

The driver is denying involvement and the insurance company is rejecting a claim because the witness described the vehicle as a van and the driver as male, but he did not get the van model and his estimate of the driver's age was out.

The amount involved is under my insurance excess but still substantial enough to pursue. What is my best course of action? If I pursue a case in small claims, is that against the driver and can I force his insurance company to give me his details if so?
