Hi there - the next Frugal Friends meeting is in Slough in September, so consider it a date!!
With regard to your cars, of course you should have two allowances for the expenditure, and if your IP messed this up in the original proposal - nothwithstanding you signed it - then they ought to be sympathetic to the true costs you are currently incurring. I suggest that you put down all of your expenditure, the dog's insurance as well, and present this to your IP. If there is a need to reduce your payments, then this may have to be done by formal variation at a creditors meeting.
As IPs we are not here to put our clients through a gruelling ordeal at annual review stage - but we do need to maintain a fair balance between what you can really afford and the expectations of creditors. I suspect you will fly through your review with flying colours.
Regards, Melanie Giles, Insolvency Practitioner
