The other Insurer told me I could be liable for costs if I don't claim through them, is this True?

This is a common tactic used by Third Party Insurers and Solicitors to persuade claimants to proceed with them directly – so that they have better control over the claim costs that they will ultimately be liable for.

You are allowed to claim directly through the Third Party Insurer if they offer their services to you at the appropriate time and you wish to accept their offer, however if you were to do this, we would be unable to step in to assist you if you had any issues with them (problems with the repairs to your vehicle for example).

You won’t be charged any additional costs (other than your policy excess) for making a genuine claim through your own comprehensive insurance policy with us.
