Should I pay for a doctors up to date letter to support claim

Thank you so. I have I have paid for a letter and am awaiting apparently up to 21 days. I am a bit nervous as had a fantastic doctor by my surgery moved and have had huge staff changes and never seen the doctor who is writing the letter. I did however tell them how it affects me so am really hoping it will be a true reflection .

If you are not happy with the letter, ask for a redraft and ask for your notes/ comments to be included.

I have been fighting the DWP since March 2021 to try and get PIP.
After the MR they still had awarded me only
2 points, so MacMillan's suggested I try to get a Doctor's letter ready to go to appeal.
Got the letter sent off, free of charge btw, on Thursday got a call out of the blue from the DWP saying I had been awarded the enhanced rate, 12points!
So I would say, even if you have to pay for it, it's worth getting a Doctor's letter
