Sharing from experiences of dealing with debt
The greatness of a man is not in how much wealth he acquires, but in his integrity and his ability to affect those around him positively.

Opinions vary and even the Insolvency Service have said different things. I would suggest you take it as being from the date they are informed. Then, if they use the date of issue you will have a small bonus -- it should only be a small difference anyway.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
