if you get sent a health assesment form for esa ,and your award changes from work related to the support group , do you get backdated and would it be from the date they requested you return the form , or would it be only paid from the decision was made, as i thought it would be backdated from the time they request you to fill in the how your health affect you form ,but apparantly ive been told i wont get backpayment only from the date of decision ,, i filled in the form in febuary and only had decision a week ago,.
