Question Author
woofgang - yes i asked, people on here get very high and mighty very quickly, i do indeed have some work to do on the house, I will not have firm quotes before I take out the mortgage, a solar system could easily cost £12K, i know as of 10 minutes ago i could get it as low as £7K (because he is happy to use kit I already have and he is not a scumbag) that's a £5K difference I could legitimately end up with oh what to do with it? burn it? or put it away for future use.
Reality is that unless you are being really stupid they won't care and so long as you can pay it back.
My question was more about the official guidelines, they basically don't want you using the security of your house to make borrowing cheaper as they would rather have you use a "more appropriate" and expensive product for that.....
