Complaints procedure


Do you have a complaint?

Obviously, we want to provide you with good, fast service always. However, sometimes our services don't go exactly as you might have wished. If this is the case, please let us know and we will look for a solution, together with you.

What does Aon do with your complaint?

Naturally, we want you to be satisfied with Aon. And we will do all in our power to process your complaint to your satisfaction. In addition, your complaint is motivation for us to consider whether we can improve our services. Your complaint is registered in our complaints registration system, after which it will be dealt with by a personal complaints coordinator. They will consult with the department concerned to see how best to resolve the complaint for you. You will receive a detailed response from us within no later than 15 working days. If we need more time to settle your complaint, we will notify you of that.

Where can you take your complaint?

There are a number of ways in which you can let us know that you are not satisfied.

  • By email
    You can send your complaint by email to klachten@aon.nl or if your complaint concerns your healthcare insurance, to zorgklachten@aon.nl.
  • Your own contact
    You can always get in touch with your own contact at Aon. Problems can generally be resolved quickly and correctly in a personal interview.
  • In writing
    You can submit your complaint in writing to:
