Hi Sam
Unfortunately UC is not like IR ESA where you can get a SDP or an EDP, there are no disability premiums with UC.
If you are successful with completing your work capability form and placed in the LCWRA group then you will be eligible for an additional element with your UC worth (£341.92 pcm), if you are placed in the LCW group there is no additional element.
