ESA Denied from 18.3.2017

Hi, I am new to site.

Received my ESA letter stating I am not entitled to ESA. Was previously in support group and prior to that on Incapacity since 2004. I completed the assessment form in early 2016 and the appointment to see a HCP only came through for February 2017.

It states: Below are the decision makers reasons:

WCA Disallowance.

I have superseded the decision awarding Employment and Support Allowance from and including 17-04-13 following assessment. This is on page 5. Then it goes on to state that I am not entitled to ESA from 18.3.17 on the last page.

Does this mean that they are telling me that I cannot claim from 2013 and therefore I have been overpaid ESA and will have to pay it back.
I am so worried as this is a lot of money and I can no way pay it back.

On page one under our decision it states that although you have an illness you are now capable of doing some work, blah blah Then on page two it states because your wca shows you can do some type of work this means we cant pay you esa from 13 March 2017.Page 4 and 5 show the ponts tables and no points for the assessment.
Page 6 which is headed Below are the Decision Makers reasons for the decision on your claim. Its has a sub heading of WCA Disallowance and then it states - I have superseded the decision awarding Employment and Support Allowance (ESA) from and including 17-04-13 following assessment.

It sounds to me that they are disallowing my claim from 2013 which I think when I changed from incapacity to ESA, Originally my first ESA claim was turned down after assessment and then I appealed and was put on lower level payment until claim sorted. They then asked if I was willing to go to court which I said yes. A month or so later I had a letter stating they had revised the decision and given me ESA support group. They then sent backdated payment. Since that time I have not been asked to attend assessment or anything until I had the letter last year it was May 2016 for reassessment. The medical interview came nearly a year later.

Thank you Gordon. I hope you are right.

To be honest the wait the decision and worry about all this has made me feel very unwell. Especially the worry of me having to pay back £20k. Although this is not stated on the decision I can't see why they have mentioned it. Surely they would have just put 18.3.17.

I havent really got the strength mentally to appeal I think I would surely have a heart attack with the worry.

After working full time from the age of 16 to 36 then leaving due to complications of a broken back. I then got arthritis of both hips shoulder impingement hip bursitis and plantar fasciitis along with knee pain joint pain dizziness and hypothyroidism I havent the mental ability to take it further. I am saddened that I have to fight for this benefit that I have paid in for 20 years plus. Also my husband has always worked and paid his taxes and contributions for 30 years.

Thank you Again

I think it must be their new terminology. My letter which I've received this week also says they've superseded the decision made in 2013/2014 but from 18/3/2017 I'm not entitled to ESA.
