ESA letter on NHS App help

Hi, can anyone help please. I am appointee for our son and a letter from ESA has shown up on his NHS app. As far as we are aware he is already in the ESA support group and has been since 2017 with his last review in 2019. The letter states his WCA as of 2nd December 2024. We have not had any letters about a review or anything else apart from his last benefit award/uprating letter for 2025 in March 2025 the one you get every year with the new rates on. The last letter had a breakdown of his entitlement and stated support group. However I am really concerned that this letter on his medical record states work related activity group/support group. I am confused as I thought you could only be in one or the other. Can anyone let me know what this could mean as we have not been asked to fill any review forms out and he has yet to get his migration letter for Universal Credit. Many thanks.

Hi, thanks David. Rang GP and they said the letter was sent to the surgery and they just upload it onto his NHS app. We were just concerned that the date says WCA Effective Date 2 December 2024. Does this mean they have done a reassessment without our knowledge. The letter is dated 29th March and was recieved by GP on 7th April 2025. I don't have time to sit on hold for over an hour with DWP as it's all I have done over the past 4 weeks with them dealing with other issues such as his SDP payments. My mind is on overload at the moment as we are also dealing with a mandaory reconsideration for backdated SDP. I just wondered if it was something that anyone else had come across. Many Thanks.

Thank you, I just didn’t have the energy mentally to have rung up today. I will try next week, it’s not easy juggling working and looking after 2 disabled adult children but I really do appreciate the help on here.
