Hi,Nitram has posted eligibility criteria.
I found once I made contact with the L A the process was quick. I received the form from them in a week. I completed it including permission for them to contact the GP and three weeks later I received a letter awarding the disregard. I also got a refund as the disregard had been applied to the previous September when diagnosis had been registered at the GP surgery.
Well worth doing if there is only two adults in the house. Best wishes
