I've received both UC and ESA, even though I've been transferred over to UC...

Hi.

I was told that income related ESA was ending and that I was to be transferred to UC. I went into the job centre well over a month ago to prove my identity. I was told via a letter from ESA (dated 24/02/25) that my last payment of ESA would cover the period of 05/02/25 to 18/02/25. I assumed that my last payment would be two weeks ago. I used to receive £318.10 every two weeks from ESA (£636.20 a month) and I was in the support group.

I was told that my first UC payment would begin today (which it has) and that I didn't need to do anything. UC told me via the journal that everything would be sorted automatically.

This is what I'll be getting every month from UC:

Standard Allowance (You get a standard allowance: You said you're single): £393.45

Limited capability for work and work-related activity (You said your health affects you at work or prevents you from working): £416.19

Transitional Protection (Your universal credit claim is not less than your previous benefits, so we have not added an extra payment): £0.00

Total entitlement before deductions: £809.64

What we take off (deductions)

As you received benefits you were not entitled to:

Employment and Support Allowance (-£20.85)

Your payment this month was £788

What do they mean 'not entitled to'? I was on income related ESA and have been transferred to UC.

Also, today (the first day of my first ever UC payment) I also received a payment from ESA of £276.40 (it would usually be £318.10 every two weeks). I don't know why I'm receiving anything from them at all.

I was told that all of this would be done automatically. It's causing me a lot of confusion and stress. What should I do?

Any help is greatly appreciated.

Thank you.
