Hi
Some ask for payments upfront,some don't.
There is no problem with upfront payments as long as you have it in writing what it is for and will it be refundable.
If no refund is given on an unsuccessful application then I would walk away and find another provider.
IPs put alot of work into a proposal and you can understand that they may want to see a commitment from the debtor by way of starting payments.Most IPs will ask you to cease paying all unsecured debts when you have decided on an IVA[quite rightly] and this money can be used to commence payments towards your IVA.
Just be sure to get something in writing regarding the refund.
