esa from april 2013 to now

hi everyone, my husband has been on esa due to disabilities for several years but has today been sent a letter. it states he is getting contribution esa but says they need to look at his claim to decide if he may also be eligible for income-related esa from 10th april 2013 to now and has been sent a form (esa 3, ) to fill in. could anyone help with what they are expecting us to do, is it something to worry about. thank you in advance.

Hello,
I recieved one of these forms 2 weeks ago and am concerned that it may trigger a reassessment.
I am not coping well at all atm and can't face dealing with it. The form took 6 days to arrive from them and says it can take 7 days to reach them if you send it back which has to be within one month of the date of the form 14th oct.
I know that untill sept 16 I definately would not qualify re saavings but am below limit now. I get an ill health occupational pension and cannot see how I would be entiitled to IR esa and can't find half my paperwork. Could you point me to a place where I could calculate whether I would qualify? I am thinking of just sending the reply slip back and saying I'm over the limit as I just cannot cope with it. Any help would be appreciated. Thank you.

Thanks Gordon. I need to know hw much weekly income you are allowed to have before you are unable to recieve ir esa. I obviously don't go to work am in the support group and have no partner. can't find out wgere to look re other money coming in weekly. I don't think i'd qualify based on the occ pension. Also the letter says tell us from the date you moved over up untill now. Does this mean that if Iknow that i wouldn't have qualified on my chnge over date that i should just send the reply slip back and tell them the reason why i don't ant them to look again at my claim? As you have to give a reason back then i was over savings limit. Thanks.
