I too went Bankrupt for Personal Reasons in January 2006 and although discharged after 12 months, I have to wait until January 2012 before it is removed from my credit file. I thought at the time Bankruptcy was the right thing for me, with £30,000 in debt I was struggling. However, if I could do things differently now I would have sold my home and paid as much off the debt as I could and either gone for an IVA or a loan to pay off the rest. Please ensure if you are ever considering your options you look at every possible option, its not always the best answer.
3 Years on, I have a bank account with Debit card from Barclays and a Visa with a credit Limit of £250 ... not much I know but its a start to build up my credit rating. I am looking at a car purchase now and looking at the loans that are on offer, it isn't easy and you end up paying almost double what your average Joe is paying but at the end of the day they have to cover their risk in this current climate.
I have got copies of both Experian and Equifax files, check both as they sometimes contain different information and just cause one of them updates the details, it doesn't mean the other company will automatically too.
All I can advise is please be weary of the advice you are given and check out all options before making a decision, I am trying to build my life back up and its tough!
