Hi nmk and welcome to the forum
I am one of the experts who regularly posts on the forum, and can give you the benefit if my experiences as a practicing IP. Other experts may have differing views, so do be sure to read all of the posts.
If you feel that the figure suggested to you is too high, then you should not enter into an IVA. You will struggle to make the payments, and the whole thing will fall into jeopardy. Was this figure actually calculated by reviewing your actual income and expenditure, or was it the lowest figure possible to provide a minimum dividend of 25p in the £?
I do not think that an offer of £11,000 alone into an IVA would also be acceptable to the creditors, as the return would be much lower than 25p in the £ taking account of IP costs. But best to speak to your nominated IP directly to see if they feel that would be a viable offer.
