UC possibly higher than legacy benefits - what to do?

Hi,

I've been helping a friend with their migration from ESA and Housing Benefit to UC. After a bit of a false start (the first payments included no transitional protection or housing element) they eventually adjusted the amount, so it now includes the standard element + LCWRA + housing element + transitional protection.

But we've just been doing the maths and it seems like they are now getting more in total per month than they did when they received ESA and Housing Benefit. Have we missed something? Should we contact the UC helpline? Should we ask in the journal for a breakdown of how they calculated the amount?

Obviously, it's nice to get more money, but they're worried they'll be asked to pay it back or get into trouble.

Thanks in advance!
