Appeal won esa and uc can't decide if I can go back,on esa

Just to reiterate poppy's post.

UC    Basic  Amount     £318 pm
         LCW addition       £126 pm

I'm assuming (as you haven't told us otherwise). that you have no rental costs - is this right?

If your monthly self-employed cash flow is less than £503 pm  (which I am assuming it is apart from that one month).

Your UC will be £444 pm, which is equivalent to the ESA WRAG you were likely receiving of £102pw 

As per my earlier posts - because you are in the LCW group the minimum income floor does not apply.
So, you should have been paid the above amount per month from the time you claimed UC.
It is because the DWP have assumed a MIR that you have received no UC (MIR is more than your UC entitlement).
The DWP are incorrect in applying the MIR -  so you need to challenge their decision by requesting a MR

"Will call them tomorrow and see what I have to do,next."

You need to reopen your UC claim - I think there is a rapid reclaim button on your journal.
You need to tell them / provide proof of the ESA tribunal decision, and your LCW status. 
As above - you need to challenge the incorrect MIR decision by requesting a MR  

Per my post on March 17th.

You should be receiving the above amount of UC (subject to earnings) ongoing, and a recalculated backdate from the start of your claim. For the month your earnings were above £503 the UC will be a lower figure than £444.

Are you receiving Council Tax support?
