Write to their GP: letter builder
The words are hard to find when you're worried. Fill in the blanks and this puts them into a clear letter you can print or copy.
A GP may be unable to discuss a patient with you without consent, but they can listen to information you provide. Where possible, tell the person that you are writing. A letter can still be useful when that is not possible.
Nothing you type is saved or sent. It stays in your browser. Fill it in, select Build the letter, then print or copy it.
