applied for UC when was mentally unwell

Hi gazzmg,

Your ESA and HB will have been closed automatically when you claimed UC.
You need to make a new UC claim asap and then request backdating and a Mandatory Reconsideration of the previous closure. We can assist with these once you are ready to make a new UC claim. But I think the best course of action would be for you to phone Citizens Advice Help to Claim and explain your situation. They will help you make a new UC claim and with the backdating and maybe with the Mandatory Reconsideration. The Citizens Advice Help to Claim phone number is
Call our national phone line
