I have received an ESA3 form with a letter stating that I receive ESA(CB) but might be eligible for ESA(IR) from 2012 (date I was transferred from IB To ESA). I, however, sorted this out with DWP in 2015 when I realised I was eligible for an IR top-up. Consequently, I received (and am still receiving) premiums ( ie ESA(IR) top-up), backdated to 2012. Thus, I am certain that DWP owe me no money.
Should I still complete the form, but inform DWP in Part 20: Other information, that this form was sent in error?
