There are advantages to both routes. If you try directly then you may be lucky and get away with not paying any professional fees - therefore more money available for creditors - but it could take for ever and a day to broker individual deals depending on the number of individual creditors you have.
By doing it through an IVA, your creditors all have to make a decision on a specific day in time as to whether they are accepting or rejecting. Your case will also be dealt with by specialist IVA voting teams within the banks, whereas it can be a nightmare trying to find a decision maker using the informal route.
I suggest you see how much could be raised, and importantly whether you can pay back a higher mortgage, before proceeding further. You must certainly not make your financial situation any worse.
