Hi Elizabeth
Beware anyone who tells you that you are only allowed to spend a certain amount on categories of expenditure. The CCCS guidelines, which the majority of creditors now use as a test of reasonableness, do not dictate how much should be spent on fuel costs, and as you say how on earth are you supposed to reduce something you have no control over.
From your post it looks as if you have debts of £40k and your husband £10k which he is servicing within a DMP. And you have equity of £40k - therefore £20k each, assuming that you own the property in equal shares. How much do you think you can afford to offer to creditors on a monthly basis, after taking account of all of your household and personal expenditure, and your husband's DMP payments? And how does this figure compare with that Payplan told you you could afford?
