LCWRA. BACK PAY

hi,

Today I received back pay of £1294 due to I assume going from ESA to LCWRA. Obviously it’s a nice lump sum which will enable us to put additional money on gas/ electric. Enjoy a few luxury items At Christmas and pay off the small amounts debt we have.
however, I don’t want to touch this money until I know I can, I won’t lie it’s a godsend at this time of year, but I believe UC will be taking back some if not all of it. I’ve asked that question in my journal, but I don’t understand why the system doesn’t just take the money it’s due, instead of paying you and dangling the temptation like a golden carrot to languish in your account when your at home rationing your food, heating, fuel, and water. What would you do???
