New Style ESA - losing transitional protection?

Hi there still trying to find out if my son can just do his migration claim with UC - not claim the ns esa. But i tried to speak to advisors in UC they all say something different.
I just asked this and she said he would get the Main payment for migrating IR esa - BUT doesn't know if he would be automatically be put in the LCWRA group (he was in support group esa) as it might not class as migrating over if he cancels esa and he could lose his transional protection
So i dont know what to think i thought he would just get main payment the payment for LCWRA but they say could also one said he might have to have assessment

I phoned the Duc migration helpline and UC claim dept they all say something different

Hi David I have another query sorry when we get this phone call for ND ESA commitments should I refuse if I'm appointee. What happens then if he's not done commitment?

Hi David I think it was someone in UC migration helpline
