Why cite NHS guidelines in the first place
The NHS guidelines GPs are expected to follow are produced by NICE (the National Institute for Health and Care Excellence), so what most people search for as "NICE guidelines" and what the NHS calls its clinical standards are the same documents. The General Medical Council's Good Medical Practice requires doctors to keep their practice up to date and to be able to justify departures from accepted standards. These guidelines are the accepted standard for most conditions.
When you cite a NHS guideline in writing, you do three useful things at once: you anchor your request in something your GP can't dismiss as "patient opinion"; you create a written reference your GP has to address; and the letter (and any response) becomes part of your medical record.
Finding the right guideline
Go to nice.org.uk and search for your symptom or condition. Every guideline has a code:
- NG, current NHS guidelines Guideline (e.g. NG87 adult ADHD, NG188 Long Covid, NG73 endometriosis, NG193 chronic primary pain).
- CG, older Clinical Guideline, still in force unless replaced (e.g. CG142 adult autism).
- QS. Quality Standard, a short summary of NHS guidelines's expectations.
- TA. Technology Appraisal, usually about a specific drug or treatment.
Always cite the most recent in-force version. NHS guidelines pages list any updates near the top.
Quoting it correctly
Two rules. First, quote the recommendation, not your interpretation of it. Use the wording from the "Recommendations" section, with the section number. Second, link to the page. Your GP can verify in two clicks, which makes the letter much harder to brush aside.
Example: instead of "NHS guidelines say you should refer me", write: "NHS guideline NG87 (1.3.1) recommends that adults presenting with symptoms of ADHD in primary care should be referred for assessment by a specialist psychiatrist, nurse consultant or other appropriately qualified healthcare professional."

Frequently asked questions
Why cite NHS guidelines in a letter at all?
NHS guidelines are the de-facto standard of care GPs are expected to follow. Citing the specific guideline number turns a request into a documented clinical reference your GP has to address explicitly in your notes.
How do I find the right NHS guideline?
Search nice.org.uk for your symptom or condition. Every guideline has a unique code (NG, CG, TA, QS). NG = current NHS guidelines Guideline; CG = older Clinical Guideline still in force unless replaced; QS = Quality Standard summarising NHS guidelines expectations.
Can I cite NHS guidelines if I'm not a clinician?
Yes. NHS guidelines is public, written for both clinicians and the public, and explicitly intended to inform shared decision-making with patients. Citing it isn't presuming clinical authority, it's referencing the same standard your GP is expected to use.
What if my GP departs from the guideline?
GPs can depart from the NHS guidelines, clinical judgement allows for it, but the GMC's Good Medical Practice requires the reason to be documented. Asking for that reason in writing is a polite, professional escalation that almost always changes the conversation.
