Accident claim

[Martiens]

Need urgent help and advice! I've been in an accident. Partly due to my status as a visitor to the UK the Insurance Company found a loop and now refuse to cover the damage to my car. I now need to get the insurance details of the other vehicle to lodge claims against that driver. Police report and witness statements clearly indicate other party as negligent in causing the accident. I'm in the process of emigrating from South Africa and money is very tight!
What do I need to do to lodge a private claim against the suspected guilty party for the replacement of the vehicle I was in?
Anyone with advice of the how, who and costs involved?
Any websites or search engine through which one can get insurance details of a car?
Thanks
