Welcome to One Underwriting

One Underwriting is the largest authorized underwriter in the Netherlands. We have been granted authorization (power of attorney) by a large number of insurers to independently accept insurance policies and review claims concerning damage, income, and healthcare insurance policies.
For clients such as you, this offers many benefits. For example, we can offer you quick policy delivery, and our own claims department can quickly and professionally handle claims. Everything is immediately arranged within our company, which is part of Aon Nederland.
