Thank you for your question. if this is a no fault claim then just ignore your insurance company and go to your solicitor who can intimate a claim to the third party insurance company for you in respect of the claim you have. There is no need to go through your insurance company and your solicitor's costs should be paid by the other insurance company over and above the amount of your claim. However, make sure that your own insurers is now covering the vehicle as modified. i hope that helps. Please leave a positive rating so that I am credited for my time.
