Hi Anna
Sorry to hear about your accident. Dont worry, there is nothing wrong with using an accident managment company if you wish to do so. The only thing you ought to do is deal with the third party's insurers for the repair to your vehicle and replacement while the repairs take place, otherwise you will be given a credit agreement by the management company and they will recover the cost directly from the insurers, however this can be a long drawn out process.
My advice however is to allow the Accident Management Company's solicitors to continue to deal with your injury claim. My reason for this is that they will provide you with professional advice regarding the value of your claim and will take away the stresses of you dealing with it. It can be a complicated and drawn out process and the solicitors costs will be paid for by your oponent's insurers. You will not have to pay anything, but confirm this with the solicitors and make sure you will get 100% Compensation also and the Accident management company dont take any.
So in short: -
Let the other partiy' insurers deal with the damage to your car and provide a replacement.
Have the Solicitors deal with your personal injury claim but check the following:-
1. It is NO WIN NO FEE and their costs will be recovered from the opponent when you win the claim
2. NO ONE takes anything from your compensation at the end of the claim and the cheque for compensation gets sent DIRECTLY to you and not via a third party ie the Accident Management Company.
Hope this helps and good luck anything else reply here and I'll try and help!
