Hi
I was in a similar bad credit rating (not my fault, but the dreaded CSA who totally screwed my finances) so after being denied by a couple of card companies, I wrote personally to Barclaycard explaining my situation and asked for a card with just £250 credit, they were quite sympathetic and after telephoning me to clear up a few questions they gave me a card with a £250 limit, this is all I needed to start again as I order most of my stuff over the internet as I work early in the morning til quite late at night.
Just BEWARE the APR is very steep @ 29.9% but as I pay every month off in full I get no interest charges
I have been with them now for 4 years and my limit is now £600
I say thanks to Barclaycard for giving me another chance to becoming debt-free and repairing my credit score
