Council says I receive far more UC than I do – ESA confusion, care charges

I’m really confused and hoping someone can help me understand what’s going on, because the figures just don’t make sense.

My council insists that I receive around £244 per week in Universal Credit. In reality, my actual UC payment is £451 per month. I have sent them my Universal Credit breakdown statements to prove this, but they are still insisting that I receive almost double what I actually get.

I contacted Universal Credit about this, and they replied saying that the council might be including my ESA in their calculations. This is confusing in itself, because for years my council reports have never shown ESA separately, and it’s never been listed as part of my income on previous assessments.

This leads me to my main question:
When you receive both Universal Credit and ESA, are they separate benefits?
Because from my understanding, my UC calculation already takes ESA into account, so it shouldn’t be added on again as extra income.

What makes this even more frustrating is that before moving to Universal Credit, I was receiving double ESA and only had to pay £9.60 per week for care.
Now I’m receiving less overall income, yet I’m being told I need to pay more for care, £93 a week, based on income figures that don’t reflect reality.

So right now it feels like:

• I’m getting less money than before
• The council thinks I’m getting far more than I actually am
• ESA may be being counted in my UC subconsciously
• And I’m being charged more as a result

Has anyone else experienced this when moving on to Universal Credit, but still staying on a lower ESA?

How do I get the council to correctly assess my actual income, rather than using figures that don’t match my UC statements?

Any advice on how to challenge this or who to escalate it to would be really appreciated.

Thanks for reading.
