The IP responded to me as follows:
It may be possible to propose a variation to reduce the term of the arrangement to 5 years. Any small debts that were not originally included should be advised and brought into the arrangement, they will automatically be bound by the terms. It may then depend on how much the overall dividend is affected as to what is possible, but if the variation is put forward together with the prospect of some increase in contributions, there is every chance it could be acceptable to creditors. However, if we are just asking creditors to reduce the term of the arrangement by 12 months without any specific reason or benefit to them then it is likely they will not accept such a variation. If there is a real prospect of a settlement offer in the next year or two then if the details are advised there may be a good chance of it being accepted. There is certainly no benefit in settling smaller creditors and just leaving HSBC and the comments regarding preferential payments are correct.
Good luck - write and see what response you get.
