ADHD Assessment UK: NHS, Right to Choose & Private (2026)

How Do You Get an ADHD Assessment in the UK?

To get an ADHD assessment in the UK, start with your GP. If they agree an assessment is appropriate, they can refer you to your local NHS service, or, if you live in England, to a provider of your choice under the NHS Right to Choose scheme, which is often the faster route. Private assessments are quicker still, typically costing £500 to £2,000.

That is the short answer. The longer answer is what this guide is for: which route suits your situation, what the waiting lists actually look like right now, how Right to Choose works in practice (including what to say to your GP), what a private assessment really costs once ongoing care is factored in, and what happens after a diagnosis. Each step links to the official NHS and ADHD UK resources so you can check the current position for your own area.

Step 1: Recognising the Symptoms and Screening Yourself

Before approaching your GP, it helps to understand what an assessment looks for. The NHS describes adult ADHD symptoms in two groups, and most people show signs of both:

• Inattentive symptoms: being easily distracted or forgetful, finding it hard to organise your time, struggling to follow instructions or finish tasks, and frequently losing things like your wallet, phone or keys.
• Hyperactive and impulsive symptoms: feeling restless or full of energy, being very talkative or interrupting conversations, and making quick decisions without weighing the consequences.

Two details from the NHS guidance are worth knowing. Symptoms usually start before the age of 12, so an assessment will ask about your childhood, not just your present. And ADHD is thought to be recognised less often in women, partly because inattentive symptoms are easier to miss than hyperactive ones. Many women first consider an assessment in adulthood after years of being told they were simply disorganised or away with the fairies.

ADHD also commonly travels with other conditions, including anxiety, depression and learning differences such as dyslexia. A good assessment considers these alongside ADHD rather than in isolation, which is one reason a proper clinical assessment matters more than any online quiz.

Free screening tools

A screener is not a diagnosis, but it means you and your GP have something concrete to discuss:

• The ADHD UK adult screener is a free self-screening questionnaire from the charity ADHD UK, based on recognised clinical screening questions.
• Think ADHD is an NHS GP-led service whose free screening test lets you hand your GP structured information about your symptoms and history. According to the NHS practices that use it, this improves the quality of referrals and reduces the rate at which mental health services reject them.

Bring your results to your GP appointment. A documented screener plus specific real-life examples is far harder to wave away than a vague description.

Step 2: Talking to Your GP

Every NHS route runs through your GP, so this conversation matters. ADHD UK's advice is to keep it open and frank: talk about all your mental health concerns, not just ADHD, and explain how your symptoms affect your work, studies, relationships and daily life. The goal is a wider conversation about helping you, not a yes-or-no verdict on ADHD.

Useful preparation:

• Keep a record of your symptoms for a couple of weeks beforehand, with concrete examples (missed deadlines, lost items, abandoned projects, relationship friction).
• Note examples from childhood and school reports if you have them; assessors will ask.
• Bring your screener results.
• Ask how long the local waiting list is. The answer determines whether you should consider Right to Choose or a private route, so get it on the table early.

If your GP agrees, they will refer you to a specialist service. If they decline, you have options, covered in the Right to Choose section below.

The NHS Pathway and Waiting Times in 2026

The standard NHS route is: GP referral, a wait, then a specialist assessment with a mental health professional specialising in ADHD, usually a psychiatrist or specialist nurse. It is free, and for many people it is the right choice. The catch is the queue.

The NHS itself is candid about this. Its adult ADHD page states that waiting times vary and that you may have to wait several months or years to access ADHD specialist services, depending on where you live. Demand for adult assessments has risen sharply over recent years, and capacity has not kept pace.

Because waits differ so much between areas, a national average tells you little. For current local figures, two resources are more useful than any headline number:

• Ask your GP surgery directly what the current wait is for the service they refer into. They are well placed to know.
• ADHD UK's NHS waiting times research collates reported waits by provider, and the charity's postcode search surfaces local information for your area.

Under the NICE guideline on ADHD (NG87), the assessment itself is typically a 45 to 90 minute structured discussion with a specialist psychiatrist, specialist nurse or another appropriately qualified healthcare professional. Psychologists can assess ADHD too, although they cannot prescribe medication if you are later offered it.

If the wait you are quoted feels unworkable, you do not have to simply accept it. In England, the law guarantees a choice of provider, and that choice is the single most useful thing in this guide.

Right to Choose: The Route Many People Miss

If you are registered with a GP in England, you have a legal right to choose your mental healthcare provider when a GP refers you. This is the NHS Right to Choose scheme, and it applies to ADHD assessments. In practice it means that if your local service quotes a multi-year wait, you can ask to be referred instead to any provider in England that holds an NHS contract for ADHD services, including independent clinics that run NHS-funded pathways with much shorter queues.

It remains an NHS referral, so it is free at the point of use. You are not paying privately; you are exercising a choice the NHS itself provides.

How Right to Choose works, step by step

1. Do your screening and GP preparation as described above.
2. Pick a provider. ADHD UK's Right to Choose page maintains information on providers that accept Right to Choose referrals for ADHD; established names that have operated NHS-contracted ADHD pathways include Psychiatry UK and ADHD 360. Provider lists and waits change, so check the current position before you commit.
3. Ask your GP to refer you to that provider under Right to Choose. Name the scheme explicitly. The referral is made by your GP, so this is a request you make in your appointment.
4. The provider assesses you on an NHS-funded pathway, and if the outcome is a diagnosis, arranges next steps, which commonly include a shared care agreement back to your own GP (more on that below).

If your GP refuses

GPs cannot generally refuse a valid Right to Choose request in England, but some are unfamiliar with the scheme. ADHD UK publishes a downloadable support letter you can take to your appointment that sets out the legal basis. Beyond that, the charity suggests several routes when a GP declines to refer at all:

• Get a second GP opinion, either informally by booking with a different doctor at the practice, or formally via a request to the practice.
• If your practice is small and options are limited, you can change GP practice; the NHS find-a-GP service lists alternatives, including predominantly online NHS GP services.
• If you are told there is no ADHD service in your area, NICE guidelines still apply in England, Wales and Northern Ireland, and your local NHS has an obligation to fund the service elsewhere through an Individual Funding Request (IFR). ADHD UK explains the IFR process.

Private ADHD Assessments: Costs and Trade-offs

The private route is the fastest, with assessments often available within weeks. You book directly with a clinic, no GP referral required in most cases, and pay for the assessment yourself. Based on the providers we reviewed, an initial adult ADHD assessment in the UK typically costs in the region of £500 to £2,000, with the price varying by clinic, location and how comprehensive the package is. Always check current fees directly, and be clear what the quoted price includes: some packages cover only the assessment, while others include the follow-up appointments you will need if medication is started.

The trade-offs to weigh before booking

• Ongoing costs. A diagnosis is the start, not the end. If medication is recommended, the dose-finding period (titration) involves several follow-up appointments, and private prescriptions carry their own costs until your care transfers to the NHS.
• Shared care is not guaranteed. After a private diagnosis, your clinic may propose a shared care agreement so your NHS GP takes over routine prescribing. GPs can decline shared care with private providers, and some practices do. Ask your own GP about their policy on shared care with your chosen clinic before you spend the money. This single question saves people a great deal of frustration.
• Check the clinician's registration. ADHD UK recommends confirming that the assessing clinician is registered with the General Medical Council; the GMC register is searchable online.
• Right to Choose may get you the same clinic for free. Several private providers also run NHS Right to Choose pathways. If your preferred clinic is one of them and you can tolerate a somewhat longer wait, the NHS-funded route may make more sense.

What Happens During the Assessment?

Whichever route you take, the core of an adult ADHD assessment is a structured clinical interview. The specialist will take a detailed history of your symptoms, focusing on when they started (particularly before age 12 and how they showed up at school), and how they affect different areas of your life: work and education, family and friends, and your medical and mental health history. With your consent, they may also want input from someone who knows you well, such as a partner, parent or close friend.

Alongside the interview, clinicians use standardised tools. The names you are most likely to encounter:

• DIVA-5 (Diagnostic Interview for ADHD in Adults): a widely used structured interview that walks through the diagnostic criteria with concrete examples from adult and childhood life.
• Conners' Adult ADHD Rating Scales and similar questionnaires, which build a detailed picture of how your symptoms present.
• The QB Test: a computerised test that measures attention, impulsivity and activity levels while you complete a 15 to 20 minute task. Some services use it as objective supporting data alongside the interview, not as a standalone diagnosis.

Be honest and thorough, including about anything you suspect is unrelated. The assessor's job is to understand the whole picture, including conditions that can co-occur with or mimic ADHD, such as anxiety, depression or autism, so the more complete the information, the more accurate the outcome.

Scotland, Wales and Northern Ireland

Right to Choose is specific to NHS England, so the picture differs in the devolved nations:

• Scotland follows its own clinical guidance system (SIGN rather than NICE). Referral is through your GP to your health board's mental health or neurodevelopmental service, and waits vary by board. Private assessment is available in the main cities.
• Wales follows NICE guidance. There is no Right to Choose, but if no local ADHD service exists, the Individual Funding Request route applies, and your GP can refer you out of area.
• Northern Ireland also follows NICE guidance. Referral is via your GP or your local Health and Social Care Trust to mental health services. Adult ADHD provision remains patchy, and many people in NI use online or cross-border private assessments; the same shared-care caution applies.

In all three nations, the preparation steps in this guide (screening, symptom records, asking about waits) work exactly the same way, and ADHD UK's resources cover the whole of the UK.

After Your Diagnosis: Titration and Shared Care

A diagnosis opens doors rather than closing the story. Your specialist will discuss what support fits your situation, and the NHS is clear that not everyone needs or wants medication for ADHD.

• Medication, if you choose it, must be started and monitored by a specialist. Options include medicines such as methylphenidate or lisdexamfetamine, and it is common to try more than one before finding what works. The dose-finding period is called titration, with regular check-ins on response and side effects.
• Shared care usually follows successful titration: a formal shared care agreement between your specialist and your GP allows the GP to take over routine prescribing, with the specialist remaining available. ADHD UK notes that shared care or GP care is the most common long-term arrangement.
• Talking therapies such as cognitive behavioural therapy (CBT) or mindfulness may be recommended alongside or instead of medication.
• Lifestyle foundations matter regardless of the route: the NHS highlights regular exercise, consistent sleep habits and a balanced diet with regular mealtimes as genuinely useful levers for managing symptoms.

One legal note: you must tell the DVLA if your driving is affected by your ADHD or your ADHD medicine. GOV.UK has the details.

Many people also describe a wave of mixed emotions after diagnosis: relief at finally having an explanation, alongside grief for the years spent without one. Both are normal. ADHD UK's support groups exist for exactly this stage.

Practical Support While You Wait

A long waiting list does not mean nothing can change in the meantime. Several forms of support do not require a formal diagnosis at all:

• Reasonable adjustments at work or in education. You can request changes such as a quieter workspace, written instructions alongside spoken ones, or help structuring tasks. Employers and universities can make these adjustments based on need; a diagnosis strengthens the case but is not always a precondition for informal changes.
• Access to Work. This government grant scheme funds workplace support for people whose health affects their work, and ADHD UK highlights it as significantly underused, with support packages worth up to £66,000 available in some cases.
• Support groups. ADHD UK runs free online support groups and large peer communities. Hearing how others handled the same waiting list is worth a great deal.
• Self-management habits. The same NHS lifestyle advice that helps after diagnosis helps before it: exercise you enjoy, a regular sleep routine, regular meals, and telling the people close to you what you are dealing with.

Supporting Your Focus While You Navigate the Wait

A note from us, kept deliberately separate from the clinical pathway above: nothing on this page is a substitute for a proper assessment or for whatever care your clinician recommends. The assessment journey is the main event, and we would encourage anyone who recognises themselves in this guide to pursue it.

That said, everyday focus and concentration are things you can support nutritionally while you work through the steps. The brain runs on nutrients: zinc, for example, contributes to normal cognitive function. Brainzyme® FOCUS PRO™ is a plant-powered, vegan food supplement made in Scotland with scientifically proven ingredients supporting concentration, mental performance and energy. It is GMP-certified and trusted by over 120,000 customers, and PRO™ is the motivation formula in the range, built around strong focus and a motivated mood for demanding workdays.

If you want to dig deeper into the wider topic first, our guide to focus supplements and nutrition covers the evidence in detail, and our comparison of focus and concentration pills maps the options available in the UK.

ADHD Assessment FAQs

How do I get checked for ADHD in the UK?

Take a free screener (ADHD UK's adult screener is a good start), book a GP appointment, and bring specific examples of how your symptoms affect your life. Your GP can refer you to your local NHS service, to a provider of your choice under Right to Choose if you are in England, or you can book a private assessment directly.

How long is the wait for an NHS ADHD assessment?

It varies widely by area. The NHS states that you may wait several months or years for ADHD specialist services. Ask your GP for the current local figure, and check ADHD UK's waiting times research for reported waits by provider. If the quoted wait is unworkable, Right to Choose lets patients in England switch to a shorter NHS-funded queue.

Is Right to Choose really free?

Yes. Right to Choose is an NHS England scheme, so the assessment and the NHS-funded pathway that follows cost you nothing. You are choosing which NHS-contracted provider carries out your care, not going private. The referral still has to come from your GP, so raise it by name in your appointment.

How much does a private ADHD assessment cost in the UK?

Expect roughly £500 to £2,000 for an initial adult assessment depending on the clinic and what the package includes. Budget beyond the headline figure: titration follow-ups and private prescriptions add to the total until your care transfers to the NHS, and that transfer depends on your GP accepting a shared care agreement, which is worth confirming before you book.

Can my GP refuse to refer me for an ADHD assessment?

A GP can decline a referral if they do not think it is clinically indicated, but you have routes forward: ask for a second opinion at the practice, register with a different practice, or use ADHD UK's Right to Choose support letter if the issue is the scheme rather than the referral itself. If there is no local service, the Individual Funding Request process obliges your local NHS to fund care elsewhere.

What is the 1-3-5 rule for ADHD?

It is a popular planning method for difficult-to-start days: commit to one big task, three medium tasks and five small ones, and count the day a success when they are done. It works because it converts an overwhelming to-do list into a fixed, finishable shape.

What is the 20-minute rule for ADHD?

Another widely shared self-management technique: work on a task for just 20 minutes, with permission to stop afterwards. Starting is usually the hardest part, and twenty minutes is small enough to begin yet long enough to build momentum. Pair it with a visible timer and a short break between rounds.
