Hi philg and welcome to the forum
Do you mean if you are looking to put forward an IVA? IP fees range from approximately £4,500 to £10,000, depending upon the type of IVA and its duration. But these fees are negotiated with creditors, and are drawn from the money you would pay into the IVA - so effectively they are borne as a creditor expense.
This would not be the case if you were offering your creditors a full repayment, in which case you would effectively be paying the fees by nature of the additional payments you would need to make on top of the payments for creditors.
Most insolvency practitioners will not ask you to pay anything to them up front, until a creditors meeting has been called.
