Ok.
Back of a fag packet calculations here, but if this is a single case then a rough dividend seems to be 40 odd pence in the £. If it is a joint or interlocking case then the dividend will be less, but conversely if the Everyday is a joint debt then their dividend is of course higher as they are getting paid from both cases. This is a very fair offer and it is no fault of yours that Everyday have acted in what seems like an unreasonable and potentially bullying fashion.
You could consider the following:
1. Increase your offer of monthly payment to increase the dividend, they may accept if it goes over 50p (not a fan of this, you may struggle by paying more)
2. Ask your I.P. to consider reducing fees to increase the dividend (they should have thought of this already and may have already done spoke to Everyday to offer that)
3. Go Bankrupt
Personally, I wouldn't recommend a DMP in any form for a number of reasons. A DMP splits payments pro rata, so the % you owe Everyday will always be the same. If you circumvent that and pay them more than the others then you are not being fair on the others, and they may then vote against you in any further proposal, so even getting Everyday under 25% does not guarantee success, and of course you have to factor in how long it would take, and how much it would cost to get it to that point.
You can pay for 2 BR's in 3 months at your IVA payment level. You then get income payments for 36 months, so 39 months in total rather than 60 on an IVA, and certainly less than, say, 6 months on DMP followed by a further 60 on an IVA after that.
This has the added advantage of returning Everday, after OR costs in BR, far less than they would have received through your IVA.
Serves them right I reckon.
