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.

As said, IP's differ in what they require. Proof of income by way of wage slips and / or bank statements and/or the latest P60. Also any evidence if expenses have changed dramatically.

My opinions are merely that .. opinions based on experience. Always seek professional advice.
