GP Won't Refer Me for ADHD? Here's Exactly What to Do Next

This Should Not Be This Hard

I am going to be upfront with you: if you have arrived at this article, you are probably frustrated. Maybe angry. Maybe close to tears. You have done the brave, difficult thing of going to your GP and saying "I think I might have ADHD," and they have said no. Or not exactly no, but something that amounts to the same thing.

"You seem fine to me." "Everyone struggles with focus sometimes." "You did well at school, so it can't be ADHD." "We don't really do that here." "The waiting list is too long, there's no point."

I hear these stories every single week in my mentoring sessions. Parents, professionals, students, people who have spent months or years building up the courage to ask for help, getting knocked back by the very person who is supposed to be their gateway to support.

So let me be useful rather than just sympathetic. There is a lot you can do here, but it works far better if you understand what your GP is actually deciding, and I would rather tell you that honestly than hand you a script that falls apart in the room.

First, What Your GP Is Actually Deciding

This is the bit most articles get wrong, including an earlier version of this one, and getting it right genuinely improves your chances.

You will read all over the internet that NICE says adults with ADHD symptoms must be referred. That is not quite what it says. NICE guideline NG87 recommends that adults presenting with symptoms of ADHD who do not have a childhood diagnosis should be referred to a mental health specialist trained in ADHD where there is evidence of typical symptoms of hyperactivity, impulsivity and/or inattention that:

1. began during childhood,
2. have persisted throughout life,
3. are not explained by another psychiatric diagnosis, although other conditions may coexist, and
4. have resulted in or are associated with moderate or severe psychological, social, educational or occupational impairment.

So the recommendation is conditional. Whether those four things are evidenced is a clinical judgement, and that judgement is your GP's to make.

I know that is less satisfying than "they have to refer you." But it is far more useful, because it tells you exactly what to walk in and demonstrate. Most refusals I hear about are not a GP defying NICE. They are a GP not being shown enough of the four things above in a ten-minute appointment. That is a fixable problem.

What I want you to know: Being refused a referral does not mean you do not have ADHD. It often means the specific evidence NICE asks for was not on the table yet. And that you can change.

Why GPs Decline ADHD Referrals

Understanding the reason helps you respond to the actual objection rather than the one you assume.

Limited Training

ADHD, and adult ADHD in particular, gets relatively little attention in general medical training. That means some GPs are genuinely less confident recognising it, especially the inattentive, masked or compensated presentation that is common in adults and particularly in women. This is a real barrier, and it is not usually malice.

Outdated Beliefs

Some beliefs persist that current guidance does not support:

• "You can't have ADHD if you did well at school." Many people compensate through intelligence, anxiety or sheer effort, often at significant cost.
• "ADHD is just a childhood condition." NG87 explicitly covers adults.
• "You seem too calm and organised to have ADHD." This is often masking, and it is exhausting to maintain.
• "It is probably just anxiety or depression." Those frequently coexist with ADHD rather than replacing it, which NG87 recognises directly in its third criterion.

If you are met with a blanket disbelief in adult ADHD, that is not a clinical reason, and it is reasonable to ask for one.

The "But You're Coping" Problem

This one really gets to me, and it maps onto the fourth NICE criterion. Many adults with ADHD have spent their whole lives building elaborate coping mechanisms. From the outside they look fine. The internal cost, the burnout, the exhaustion, the relationships fraying, is invisible in a short appointment unless you make it visible.

Which is exactly why the impairment part of your case matters most. Do not lead with how well you are managing. Lead with what it costs you to manage, and what has actually gone wrong.

Step by Step: What to Do When Your GP Says No

Step 1: Ask Exactly What Was Declined, and Why

Ask directly: "Can you explain the clinical reason you are declining this referral, and what would prompt you to reconsider?" Their answer determines everything that follows. Write it down, with the date.

It is also fair to ask: "Could you record in my notes that a referral was requested and declined, along with the reason?" That is not a threat. It creates a clear record, which helps if you need to escalate or see someone else.

Step 2: Come Back With Evidence Against the Four Criteria

If the first appointment did not go well, book another and prepare properly. Aim for specifics rather than a symptom list:

• Childhood onset. School reports, comments from parents or siblings, specific memories. Anything that shows this is not new.
• Lifelong persistence. A short timeline from school to now, rather than only how the last few months have been.
• Not better explained by something else. If you have been treated for anxiety or depression, say what changed and what did not, and which difficulties persisted even when your mood was stable.
• Current impairment, moderate or severe. This is the one people undersell. Be concrete. Missed deadlines and their consequences. Jobs left or lost. Debt from unopened post. A relationship that ended. Appointments missed. Put the cost in plain terms.

A screening questionnaire such as the ASRS can help you organise your thoughts, and it is fine to bring one. But be aware that NICE does not support diagnosing ADHD from a rating scale alone, so a high score is a conversation starter, not a trump card.

Some phrasing that tends to land better than quoting entitlements:

"I want to explain how I think I meet the NG87 referral criteria. These symptoms started in childhood, here is the evidence. They have persisted throughout my life. They were not resolved when my depression was treated. And here is the specific impairment they are causing now."

"If you do not think I meet those criteria, could you tell me which one, and what evidence would change that?"

That second question is the most useful sentence on this page. It turns a dead end into a next step.

Step 3: Ask to See a Different Clinician

You can see any GP at your practice, and some have more experience with neurodevelopmental conditions. Be aware that another clinician may reach the same conclusion, which is not necessarily a stitch-up. Reception can sometimes tell you whether a particular GP has an interest in mental health or ADHD.

Step 4: Raise It With the Practice Manager

If you feel your concerns were not properly considered, the practice manager can check whether the correct process was followed and can route a complaint. What they cannot do is overrule a clinical decision because you disagree with it. Set your expectations accordingly and you will get more out of the conversation.

Include your name and date of birth, the date of the decision, the reason you were given, and the specific outcome you want, such as a written explanation or a review by another clinician. Do not send detailed health information through an insecure channel.

Step 5: Complain to the Practice or the ICB

For primary care, NHS England says you can complain either directly to the GP practice or to the integrated care board that commissions the service. You cannot submit the same complaint to both at once, so pick the route more likely to look at it independently. Use the ICB contact directory to find yours.

Complaints should be acknowledged within three working days. There is no universal fixed deadline for the full response, but the organisation should tell you how it will be handled and when to expect an answer.

Ask for a realistic outcome: a clear explanation, correction of an administrative error, or review by another clinician. Framing guaranteed referral or diagnosis as the only acceptable outcome tends to weaken an otherwise reasonable complaint.

Step 6: The Ombudsman, After Local Resolution

If you have a final response and remain dissatisfied, the Parliamentary and Health Service Ombudsman can consider NHS complaints once the local process is complete. Independent NHS complaints advocacy may also be available through your council or local Healthwatch.

Step 7: Change Practice, With Realistic Expectations

Sometimes registering elsewhere is the simplest answer. You do not need a reason or your current GP's permission. It is worth knowing that this is not a guaranteed fix and it can interrupt continuity of care, so it is usually better as a considered choice than a reflex.

Step 8: Consider the Private Route

A private assessment bypasses the referral question, and most private services accept self-referrals. It should not be necessary, and access to healthcare should not depend on ability to pay, but for some people it is the fastest route to an answer. Costs and what you get for them vary a lot, so read ADHD diagnosis costs in the UK and NHS versus private assessment before committing to anything.

Where Right to Choose Fits

In England, patient choice can be a genuinely useful route, but it solves a different problem from the one this page is about, and conflating the two is where people come unstuck.

Right to Choose applies to which provider carries out an eligible referral. It does not override the clinical decision about whether to refer. So if your GP has declined any ADHD referral, that is the decision to address first, using the steps above. Choice becomes relevant once referral is agreed.

I have written the detail up separately, because the eligibility rules genuinely matter:

• ADHD Right to Choose: the NHS assessment guide for how it works and which providers qualify
• Writing a Right to Choose request to your GP for the wording
• GP refused ADHD Right to Choose? for when referral is agreed but your provider choice is being blocked, which is a patient-choice issue with its own escalation route

One caution, because it is a common and costly assumption: Right to Choose does not guarantee a faster assessment, and it does not guarantee diagnosis, medication or shared care afterwards. Check a provider's current waiting times and their full pathway, including prescribing and follow-up, before you commit.

What If the Referral Goes Through and Nothing Happens?

Sometimes the referral is made and then you hear nothing for months. This is unfortunately common.

• Chase it. Ask the practice to confirm the referral was sent, and to which service.
• Contact the service directly to confirm receipt and ask about expected waiting times.
• Ask about your options if the wait is very long, including whether transferring to an eligible choice provider is possible.

My guide on what to do while waiting for an ADHD diagnosis covers how to get support in the meantime, which matters, because the waits in some areas are measured in years.

Where Mentoring Fits, and Where It Does Not

Let me be clear about the boundary, because this page is about a clinical decision. I am not a clinician. I cannot assess you, diagnose you, challenge a clinical judgement on your behalf, or make a GP refer you. Nobody offering you that is being straight with you.

What I do help with is the part that trips people up: getting your history and examples into an order you can actually say out loud, deciding what to prioritise in a ten-minute appointment, and preparing for the possibility of a no so it does not knock you sideways. Executive function difficulties are precisely what make self-advocacy hard, which is a slightly cruel irony when self-advocacy is what you need to get assessed.

And if you are facing a long wait either way, that is the other half of it. We work on the systems that make work, study and home life manageable now, rather than treating the diagnosis as the starting line for everything.

You Deserve to Be Heard

I want to end with this, because I think it needs saying. Asking for an ADHD assessment is not attention-seeking. It is not jumping on a bandwagon. It is not being dramatic. It is a person recognising they are struggling and asking for help. That takes courage, and you should be met with a proper conversation, not a brush-off.

The ADHD diagnosis process in the UK is far from perfect, and the pressure on services is real. But you are entitled to a clear reason, a fair process, and a route to challenge it. And you are allowed to keep going.
