On a separate note, companies don't have to go looking to see that you've went bankrupt.

When you take out a contract, or bank account etc you are giving that company authority to tell the credit reference agency(s) how you are preforming with whatever you have taken out.

In turn the credit reference agency shares the information every month automatically with that company, its a special computer program linked into their credit systems, with equifax its called Insight.

as soon as you go bankrupt, the record for that month will be BR, and that will filter through to everyone signed up to monitor your credit file. Including O2.
