Hi andy.t and welcome to the forum
As you are in an IVA, this is a legal and binding undertaking. Initially, your IP would have applied to the court, your local one, for an Interim Order to stop all creditors bothering you, adding interest to your debt etc. So, yes, in effect, this is a court order. If I am mistaken, I am sure that Mel or one of the other experts will correct me.
As for wanting to rent a property, credit checks will be made and as your IVA will be noted on your credit file, it is up to the agents/landlords if they want to rent to you. In some cases, estate agents have asked for up to 6 months rental up-front, some have asked for a guarantor to step up to the plate for you for the same amount of time.
Hope this helps
