Overview

ADHD diagnosis requires a structured specialist assessment, usually taking several hours and drawing on developmental history. It cannot responsibly be done in a GP consultation, and we do not attempt it.

What we can do is take your history seriously, screen for the conditions that commonly mimic or accompany ADHD, and write a proper referral to a specialist service.

What this test measures

The consultation uses validated screening tools to establish whether a specialist referral is warranted, alongside blood tests where thyroid disease, anaemia or vitamin deficiency could be contributing.

Why you might need it

Worth exploring if

  • Attention, organisation or restlessness have been difficult since childhood
  • It has affected education, work or relationships across your life
  • You have been treated for anxiety or depression without much benefit
  • A family member has been diagnosed — ADHD is strongly heritable

What helps the specialist most

  • School reports, particularly comments on concentration and behaviour
  • Any previous assessments
  • An account from a parent or someone who knew you as a child

Gathering these before your specialist appointment genuinely improves the assessment.

To be completely clear

We do not diagnose ADHD. Diagnosis requires structured specialist assessment. What this appointment provides is screening, exclusion of other causes, and a well-written referral — not a diagnosis.

What's included

  • A 20-minute consultation taking a proper history, including how long difficulties have been present and their impact
  • Validated screening tools — typically ASRS and DIVA-informed questioning
  • Blood tests to exclude conditions that mimic ADHD: thyroid, iron, B12 and vitamin D
  • A referral letter to a specialist ADHD assessment service, summarising your history
  • An explanation of the NHS Right to Choose route, which costs nothing

How the referral works

Partner site:

1. Screening consultation

A proper history, not a tick-box exercise. ADHD symptoms must have been present since childhood and cause impairment across more than one setting — establishing that takes time.

2. Exclude the mimics

Thyroid dysfunction, iron deficiency, B12 deficiency, sleep apnoea, anxiety and depression all impair attention and concentration. Some are far quicker to treat than ADHD.

3. Referral

A letter to a private specialist assessment service, with your history summarised so they start from where you left off.

4. Or the free route

Under NHS Right to Choose in England you can choose your assessment provider, at no cost. Waits can be long, but it is free and it is your legal right. We will explain how it works rather than steering you toward the paid option.

Preparation required

School reports, previous assessments and an account from someone who knew you as a child are all genuinely useful to the specialist. Gather what you can beforehand.

Understanding your results

What a diagnostic assessment actually involves

Not a questionnaire. A proper ADHD assessment is a structured clinical interview with a psychiatrist or specialist ADHD clinician, typically lasting an hour or more.

It requires evidence of symptoms in childhood, before age 12 — which is why school reports and an account from a parent or someone who knew you then matter so much. ADHD is not something that begins in adulthood, though it is very often first recognised there.

It also requires impairment in more than one setting — work and home, for example — not difficulty in one demanding job.

What we can and cannot do

We do not diagnose ADHD, and we do not prescribe for it. Diagnosis is a specialist assessment, and we never prescribe stimulant medication remotely — without exception.

What we can do is prepare the ground properly: take the history, exclude the conditions that mimic ADHD, gather what the assessing clinician will need, and refer.

What gets excluded first, and why it matters

Several treatable conditions produce inattention, restlessness and poor concentration:

  • Thyroid disease — both over- and underactive
  • Iron deficiency, even without anaemia
  • B12 deficiency
  • Sleep apnoea and chronic sleep deprivation, which are strikingly similar and very commonly missed
  • Depression and anxiety, which frequently coexist with ADHD as well as mimicking it

Finding one of these does not mean you do not have ADHD. It means one contributor is treatable now, and the assessment is more accurate without it in the way.

What a diagnosis changes

Access to treatment, adjustments at work under the Equality Act 2010, and support in education.

And for many people an explanation for years of difficulty that was attributed to character — which is not a small thing.

What this test cannot tell you

What this is not

This is not an ADHD diagnosis, and no blood test diagnoses ADHD. There is no scan or biomarker for it.

Online screening questionnaires are not diagnostic either. They are designed to be sensitive rather than specific — a positive screen is a reason to seek assessment, not an answer.

What we will not do

We will not prescribe stimulant medication. Methylphenidate, lisdexamfetamine and dexamfetamine are controlled drugs requiring specialist initiation, titration with monitoring, and — in the UK — an in-person framework.

This applies without exception, including to people already diagnosed and stable elsewhere. It is not a judgement about you; it is a fixed limit on safe remote practice.

The same applies to benzodiazepines and z-drugs, which are sometimes requested alongside.

Where the private market has problems

Some private ADHD services diagnose after very short assessments with no childhood evidence and no informant account.

Those diagnoses are frequently not accepted by NHS services for shared care, which leaves people paying privately for medication indefinitely. It is worth asking any provider, before paying: how long is the assessment, who conducts it, and will an NHS GP accept it for shared care?

What we cannot assess

Children. Paediatric ADHD assessment needs school input and in-person observation, and goes through NHS paediatric or CAMHS services.

Costs explained

What you pay

  • £40 for the consultation — history, exclusion of mimics, and a referral letter
  • Any blood tests, quoted before they are arranged
  • The specialist assessment is charged by the assessing service, not by us

The free route, and Right to Choose

NHS ADHD assessment is free. Waits are long in many areas, which is the honest problem.

But Right to Choose is the single most useful thing on this page. In England, you can ask your GP to refer you to any NHS-commissioned provider — including independent providers working under NHS contract — and waits with those providers are frequently far shorter.

It costs you nothing, and the diagnosis comes with NHS shared care, meaning your GP can prescribe afterwards at standard prescription charges rather than private prices.

A great many people pay thousands privately without knowing this exists.

The cost that follows a private diagnosis

Ask before you pay: will an NHS GP accept this for shared care?

If the answer is no, you are committing to private prescribing indefinitely — medication, titration appointments and annual reviews — which over years costs considerably more than the assessment.

Where not to spend money

  • Online questionnaire "assessments" that produce a diagnosis without a clinical interview or childhood evidence
  • Brain scans, EEG or genetic testing marketed for ADHD. None diagnoses it
  • Supplements marketed for focus, where the evidence does not support the price

Common questions

Can you diagnose ADHD?

No — that requires a specialist assessment with a psychiatrist or specialist ADHD clinician.

What we can do is take the history properly, exclude the conditions that mimic it, and refer you with a letter that helps rather than one that restates a questionnaire.

Can you prescribe ADHD medication?

No, and not under any circumstances remotely.

Stimulants are controlled drugs requiring specialist initiation and monitored titration. This applies even if you are already diagnosed and stable — it is a fixed limit, not a judgement.

What should I bring?

School reports if you can find them — they are the single most useful thing, because evidence of symptoms before age 12 is required for diagnosis.

Any previous assessments, and if possible an account from a parent or someone who knew you as a child.

Gathering this beforehand makes the assessment considerably more likely to reach a clear conclusion.

What is Right to Choose and why does it matter?

It is the most useful thing to know if you are considering paying.

In England you can ask your GP to refer you to any NHS-commissioned ADHD provider, including independent ones working under NHS contract. Waits are often far shorter than the local service, and it costs nothing.

It also comes with NHS shared care, so medication afterwards is at prescription-charge prices.

Will an NHS GP prescribe after a private diagnosis?

Sometimes, but not always — and this is worth settling before you pay.

Shared care is voluntary, and some practices decline it for private diagnoses, particularly where the assessment was brief.

Ask the provider directly: how long is the assessment, who performs it, and will an NHS GP accept it?

Can ADHD start in adulthood?

No — but it is very frequently first recognised in adulthood.

Symptoms must have been present before age 12, even if nobody identified them. Many people, particularly women and girls, are missed entirely in childhood because inattentive ADHD is quiet rather than disruptive.

What else could explain my symptoms?

Several treatable things, and they are checked first: thyroid disease, iron deficiency, B12 deficiency, sleep apnoea, chronic sleep deprivation, depression and anxiety.

Finding one does not rule ADHD out — it removes a confounder and makes the assessment more accurate.

Can you assess my child?

No. Children need in-person assessment with school input, through NHS paediatric or CAMHS services.

The school SENCO is often the fastest route in, and support can begin before any diagnosis is made.

Are online ADHD tests reliable?

As a prompt, yes. As a diagnosis, no.

Screening questionnaires are deliberately sensitive, which means many people who do not have ADHD score positively — particularly when anxious, depressed or exhausted.

Questions about our service

How quickly can I be seen?

Same-day access is usually available, from 6am to 10pm, seven days a week. You choose a time that suits you rather than waiting on hold at 8am.

Will I see the same doctor each time?

Yes. Care is led personally by Dr Mohammad Khan, so you are not passed between clinicians. Continuity is the point of a small practice: someone who knows your history and is listening attentively rather than working through a checklist.

Can you see my NHS records?

Yes, with your consent. We can access your Summary Care Record during the consultation, so your current medications, allergies and significant history are in the room. That means fewer questions you have already answered elsewhere, and safer prescribing.

Are you trying to replace my NHS GP?

No. We are not here to replace GPs, only to support them. Your NHS practice remains responsible for your ongoing care, and with your consent we write to them after the consultation. We are useful when you need to be seen sooner, or want more time than a standard appointment allows.

What is included in the appointment?

Twenty unhurried minutes and a comprehensive assessment. A written treatment plan is included, along with any prescription, sick note or referral letter arising from the consultation, at no extra charge.

How much does it cost?

£40 for 20 minutes, self-pay. Membership is optional and never required. Priced for fairness, because we are not here to charge extortionate amounts for access to a doctor.

What does “treatable online” actually mean?

It means the diagnosis can usually be made from your history and photographs, and that treatment can be arranged safely without examining you. Where a condition is not marked treatable online, it is because examination is the diagnosis — listening to a chest, feeling an abdomen, examining an ear or a joint — or because a procedure or device is needed.

Can you prescribe antibiotics?

Yes, where there is a genuine bacterial infection — cellulitis, impetigo, bacterial urine infections, confirmed strep throat. We will also frequently tell you that you do not need one. Most sore throats, coughs, colds and earaches are viral, and an antibiotic gives you the side effects with none of the benefit.

What if the GP cannot help with what I need?

If your problem turns out to be genuinely outside what we can do remotely, the doctor will tell you straight away, point you to the right service, and refund your fee in full. We would rather do that than fill twenty minutes to justify the charge.

What should I do in an emergency?

Call 999 or go to A&E — do not book an online appointment and do not wait for a reply to an email. For urgent problems that are not emergencies, NHS 111 is available 24 hours a day, online or by phone, and can direct you to the right service.
