Google "sub prime lenders" - you dont want to go down this route unless you have to - at about 17% APR - you only want to borrow exactly what you need .
I know a reputable company that offer loans tailored to IVA clients and if you email me I can give you their details. I don't think I am allowed to post things directly on the forum but my email address is in the experts section and I will happily pass on the number.
Hopefully it works and you can get out of your IVA. In two years time your credit file will be completely cleared up and you can then remortgage the lot to the High Street.
