Hi I have read in the ESA guide that once you have been assessed you are no longer required to send in further sick notes, My husband was assessed in May 2021, and received at letter stating he was in the support group in July 21. They then asked for him to provide a further sick note in August 21, we tried to contact by phone to query this but unsuccessful, so wrote a letter asking why? enclosing a further sick note. Please give your opinion on this? He is on New Style CB ESA. Thanks
