Hi emma and welcome to the forum
From the information you have provided above, it seems that you are struggling to make all of your payments to creditors, without reverting to other forms of credit to top up your household expenditure. This is a dangerous situation to be in, as you debts are probably growing on a month by month basis.
An IVA is a possible solution for you, but what you need to do is list out your income and then deduct all of your household expenditure - not including any repayments to creditors. Don't forget to make allowance for contingencies such as house and car maintenance, medical expenses, clothing and a general contingency allowance to take into account unforseen, irregular expenditure. When you have a final figure, this is known as your "disposable income". When I know what that figure is, I can advise you further.
There are a couple of clear differences between an IVA and a DMP.
1 An IVA runds for a finate timescale - usually 5 years - but a DMP will continue until the debts are repaid in full.
2 Interest is legally stopped during an IVA, whereas it can continue to run within a DMP thus extending the time period even further.
3 Creditors can continue with legal action under a DMP, but they are forbidden from doing so under an IVA.
4 An IVA brings more certainty, in that you know exactly where you are on the day of the creditors' meeting, rather than living with the uncertainty of a DMP.
With regard to your employers - check your firm's handbook or your contract of employment to see if you would lose your job. If this is the case, then a DMP is possibly the best solution for you, but will take longer to conclude.
