Suggest that you call the UC helpline 0800 328 5644 to ask about the backdated payment.
What tends to happen is UC Decision Makers add the decisions to the claims and it then takes ages before claimants hear any more.
Any backdated payment for the limited capability for work and work related activity may be offered to DWP Debt Management. If you call UC, they may be able to tell you, whether this is going to happen.
If you win the ESA tribunal, then yes any further backdating will be worked out, but you will need to provide a copy of the tribunal letter to UC, so they can arrange this. DWP do not always appear to get the tribunal letters, which is why is why I suggest passing to UC via the local Job Centre.
On the issue of the tribunal, perhaps it may be worth providing tribunal details of the recent UC assessment, so they can see how the ESA assessment which found you fit for work, was an error.
