Media coverage of private ADHD assessments has, at various points, raised genuine concern about how some clinics operate. Reporting that a small number of providers cut corners is uncomfortable, but it is also useful, because it gives the public a reason to ask better questions. The right response is not to dismiss private assessment altogether, which would leave thousands of people stuck on multi-year NHS waiting lists, but to be able to tell a careful, regulated clinic from a quick-turnaround one. The good news is that the markers of quality are not secret, and you can check most of them before you book.
Why does the quality of an ADHD clinic matter so much?
An ADHD diagnosis is consequential. It can open the door to medication that is tightly controlled, to workplace and educational adjustments, and to a different understanding of years of difficulty. A diagnosis arrived at carelessly is worse than no diagnosis, because it can put someone on a treatment path that does not fit, or miss something else entirely.
A proper assessment is not a fifteen-minute questionnaire. It is a structured clinical process that takes a full developmental history, looks at how difficulties show up across more than one setting, and considers what else could explain the picture. That last part matters: anxiety, autism, sleep problems and trauma can all look like ADHD, and a good clinician rules in and rules out rather than reaching for the obvious answer.
What does a credible ADHD assessment involve?
The UK standard is set out in NICE guideline NG87, which describes how ADHD should be diagnosed and managed. A diagnosis should be made by a suitably qualified healthcare professional, based on a full clinical and psychosocial assessment, a developmental and psychiatric history, and information about how symptoms affect different domains of the person's life.
In practice, a credible assessment will:
- Take a detailed history covering both childhood and current functioning, because ADHD is lifelong and the criteria require evidence across the lifespan.
- Gather information from more than one source where possible, such as school reports or a partner's observations.
- Consider other explanations and co-occurring conditions rather than treating ADHD as a foregone conclusion.
- Be carried out by a clinician with specific training in ADHD, not a generalist working from a tick sheet.
If you want a fuller walk-through of the process, our piece on what happens at an ADHD assessment sets it out step by step.
A diagnosis is only as good as the assessment behind it. Speed is not a feature when the question is this important.
How do I know a clinic is regulated?
In England, independent providers carrying out clinical assessments should be registered with the Care Quality Commission, the CQC. CQC registration means the provider is inspected against standards for safety and quality, and you can look any provider up on the CQC website. Registration is not a guarantee of perfection, but the absence of it is a genuine warning sign.
Beyond CQC status, it is reasonable to ask who will carry out your assessment, what their qualifications are, and whether prescribing, if it follows, is handled by an appropriately qualified prescriber. A clinic that answers those questions clearly and without defensiveness is showing you something useful.
What are the warning signs of a clinic to avoid?
Some patterns should make you pause. Be wary of an assessment that promises a diagnosis in a single short appointment with no developmental history, of clinics that appear to diagnose almost everyone who walks through the door, and of any provider that bundles a diagnosis straight into a medication sale with little discussion of alternatives or monitoring.
The concern about overdiagnosis is worth taking seriously without overstating it. We have written more on this in is ADHD overdiagnosed?, and the short version is that both careless overdiagnosis and decades of underdiagnosis are real problems. A good clinic guards against both by assessing properly, not by being either generous or stingy with the label.
Does a private diagnosis count with the NHS?
This is one of the most common worries, and the answer depends partly on where you live. A diagnosis from a CQC-registered private provider is a legitimate clinical diagnosis. Whether your GP will enter into a shared care arrangement for ongoing medication, where the GP takes over prescribing after specialist initiation, varies between Integrated Care Boards and is not guaranteed. NICE NG87 supports shared care in principle, but local acceptance differs.
The practical point is to ask the clinic up front how prescribing and ongoing monitoring will work, and to be realistic that shared care is a local decision your GP is entitled to make. A reputable provider will be honest with you about this rather than over-promising.
It is also reasonable to ask what happens if your GP declines shared care. Some private providers will continue to prescribe and monitor privately, at an ongoing cost. Others operate differently. Knowing the answer before you commit avoids an unwelcome surprise later, and a clinic that has thought this through and explains it clearly is showing you the kind of careful practice you are looking for.
What does this mean for choosing between NHS and private?
Both routes are legitimate. The NHS route is free and thorough but often very slow. The Right to Choose route within NHS England can shorten the wait by letting you choose a provider. A private assessment via a regulated clinic is faster again, at a cost. None of these is the wrong choice; the wrong choice is a provider that does not assess properly, whatever the route.
If you are weighing up where to be seen, the questions are the same ones throughout this article: is the provider regulated, who is doing the assessment, how thorough is it, and how honest are they about what happens next.
What this means in practice
- A credible ADHD assessment takes a full developmental history and considers other explanations. A fifteen-minute checklist is not enough.
- Check the provider is CQC-registered in England. You can look this up yourself before booking.
- Ask who will assess you, what their qualifications are, and how any prescribing and monitoring will be handled.
- Be cautious of single-appointment diagnoses, clinics that seem to diagnose everyone, and any provider that rushes you towards medication.
- A private diagnosis is legitimate, but shared care for ongoing medication is a local decision your GP makes, so ask about it early.
