New leaflet - what you have to tell us

Hi. I have just received a scary leaflet with a letter telling me new amount for ESA starting in April. I am confused. I am on Contributions based ESA (or I was and am wondering if this has been changed) and included with the letter was a leaflet saying what you need to tell us. Well what they are saying I need to tell them is absolutely everything about my life, and my partner's life! It wants to know if I inherit any money, if I have more than £6,000 of savings, if my or my partner's circumstances have changed (my partner is not on any benefits and is a pensioner). I don't understand why they are asking me to tell them all these "changes" if I am on contributions based ESA which isn't supposed to be means tested.

In two months time I will be of state pension age. And will be done with ESA. Do I have to tell them that or will they automatically just stop it when I start getting my state pension?

Thanks Gary. Yes sorry about that. I thought the first post had not gone through so did it again - then saw the bit that said it needed to be approved by a moderator so had posted twice by mistake. Apologies. Yes I've completed the pension online thing and had a letter.
