ESA letters are always badly worded and often misleading. The letter you received a couple of months ago would have just been about your payments, not your award.
You must complete this ESA50 to continue to receive your ESA, treat it as a new claim and complete the form in detail supplying evidence as you can, even if it has been submitted before.
Although there have been no recent changes to the ESA Descriptors, the advice given by the DWP has been updated so make sure you use our current ESA Claim guides to help you complete the form.
