ESA newbie

My daughter has just applied for ESA due to ill health. She's on DLA and a student. She's taken study leave so was accepted for ESA. She's been asked to send in a sick note. Her claim is 3 months backdated. DWP has now asked for sick note from then. My question is who is the best person to give her the sick note? Her 2 hospital consultants know her condition best, but the GP simply has all her records of her condition. Since in future she'll need an assessment does it matter who gives the note? Is it the doctor who signs now who'll be contacted for a report during the assessment stage? I would like her to have a proper and truthful medical report then. Does she have to continually give sick notes till she's assessed? Finally, she's just had a PIP assessment last week to move from DLA to PIP last week. Can this report be used by DWP for her ESA assessment without informing her?

Thank you for replying so soon. Yes, she's been under care of the same doctors since she moved from peads 4 years ago. The hospital doctors gave all the reports for pip and are willing to offer any support. Her condition is from birth so she actually sees these doctors every 4 weeks. I will write about her experience for PIP when a decision is made and she receives her award. So to confirm, each fit note should be for a maximum of 3 months each, without a break? Thanks in advance.

Hi everyone. I just wanted to say a heartfelt thank you for all the guides on Benefits and Work website. The advice is invaluable. After a 6 month wait, my daughter has been placed in the support group without an assessment! Wonderful news for her. DWP sent a letter to her GP requesting an upto date health report without her knowledge about 4 weeks ago. She only got to know about this when she requested for a new fit note and had a phone consultation with her doctor. It's therefore important to keep your doctor upto date with your condition. Spread the word. Don't fill those lengthy DWP forms without using these guides on here.
