Choosing whether to pursue an ADHD assessment is rarely about wanting a label for its own sake. For many people it is about making sense of a long-standing pattern — inconsistency that others misread as laziness, overwhelm that arrives faster than expected, emotional spikes that feel disproportionate, or a quiet chronic sense that your nervous system is running a different operating system than the environments you live and work in.

At Neurodiverse You, ADHD assessment is structured to be respectful, transparent, and clinically robust. Our pathways are aligned to relevant NICE guidance and supported by recognised, gold-standard assessment tools where clinically appropriate. We combine validated questionnaires with a careful developmental and clinical interview so your history is understood in context — including strengths, adaptations, masking, burnout, and what else might explain your difficulties. Where packages include informant input, ASD screening, consultant psychiatrist consultation, or wider multidisciplinary contribution, it is because additional perspectives can strengthen formulation when complexity is present — not because we want to “catch you out,” but because ADHD presentations vary widely across settings and life stages.

We are attentive to masking, burnout, and gendered stereotypes that have historically led to misrecognition. Many adults reach us after years of coping, late diagnosis in the family, or a sudden collapse in capacity when demands stack. Others are younger people (14–17) whose families want a careful, ethical pathway with clear communication and realistic recommendations for education and home life.

Because ADHD overlaps with other profiles — including anxiety, mood difficulties, trauma-related responses, sleep disruption, and autistic traits — assessment includes attention to differential diagnosis where clinically indicated. Each package sets out what is included, from additional reporting and informant interviews to ASD screening and consultant psychiatrist consultation, so you can match thoroughness to your questions and context.

Our reporting aims to be practical: clear enough to share with a GP or educational provider where relevant, and grounded in what will help next steps feel imaginable — whether that is adjustments, coaching, further assessment, or simply a more accurate framework for self-understanding.

If you are unsure which package fits, start with an enquiry. Clinical triage helps confirm suitability, outlines timelines and fees, and keeps consent meaningful at every stage.

ADHD is a neurodevelopmental difference that can be missed in childhood, especially when someone has learned to cope, mask, or compensate. In adulthood, it may become more visible through strain around focus, organisation, emotional regulation, time, and follow-through. Many people reach us after years of coping — or burnout — and want a careful, evidence-informed formulation, not a rushed label.

Does this feel familiar?

  • You may act quickly or respond in the moment, then realise afterwards that you needed more time to think it through.

  • Organising tasks, prioritising, and keeping order feels constantly uphill.

  • Time feels slippery — you underestimate how long things take or miss deadlines.

  • You lose focus on one thing unless it is urgent or genuinely gripping.

  • When several demands arrive at once, you may feel overwhelmed quickly.

  • You feel restless or driven to move, even when you want to sit still.

  • Your mood can shift quickly, or small frustrations can feel much bigger in the moment.

  • Stress can hit hard — you may avoid, shut down, rush, or feel constantly on edge.

  • Starting is hard; finishing is harder — projects stall even when they matter to you.

  • Irritation or anger may arrive quickly when you are already overloaded.

What to expect from your assessment

Assessment is structured so we understand your story, your strengths, and what else might explain your difficulties — not a single questionnaire tick-box. Some steps vary by package — see the badges on each step.

  1. Step 01

    Initial screening

    We review screening information to confirm whether an ADHD-focused assessment is appropriate and to plan the next steps safely.

  2. Step 02

    Clinical interview

    An in-depth interview with you (and a parent or carer for adolescents) explores current difficulties and developmental history.

  3. Step 03

    Questionnaires and rating scales

    Standardised measures (Conners, SWAN, ASRS, and DIVA-5 where indicated) help quantify symptoms and how they affect daily life, study, and work.

  4. Step 04

    Informant input

    Comprehensive+

    With your consent, we gather context from people who know you well — a partner, parent, school, or workplace contact — to see how patterns show up across settings.

  5. Step 05

    Psychiatrist Consultation

    Multidisciplinary+

    The Consultant Psychiatrist meets with you and reviews you as well as any written materials from earlier assessments/materials, contributes to the formulation & discusses medication options where relevant

  6. Step 06

    Report and recommendations

    You receive a clear report with findings and practical recommendations for home, education, or work. Higher packages add a professional summary report.

  7. Step 07

    Feedback session

    Comprehensive+

    We meet with you (and significant others if appropriate) to talk through the report, answer questions, and agree next steps.

  8. Optional

    Cognitive assessment

    Cognitive testing (memory, attention, processing) to clarify strengths and difficulties — added by clinical indication or on request.

  9. Optional

    Differential diagnosis review

    Many conditions can mimic or coexist with ADHD (anxiety, mood, trauma, sleep). We carefully evaluate alternatives so the diagnosis you receive is accurate and useful.

Steps with no package badge are included as standard. Package badges show which package includes each additional step. Optional steps can be added where clinically indicated or requested.

What affects the price

  • Package depth — Core through Integration & Support add successively more (informant input, psychiatrist review, follow-up sessions).
  • Age band — Adolescent pathways include additional informant and educational-report work and are priced slightly higher than adult equivalents.
  • Optional add-ons — Workplace or educational reports, ADHD coaching, and parent guidance are priced separately.
  • Clinician mix — Pathways that include a consultant psychiatrist review are priced above the core clinician-led assessment.

Final fees are confirmed at triage, once we know which package and add-ons fit your situation.

Common questions

How much does a private ADHD assessment cost?

Our adult ADHD packages start at £900 (Core) and range up to £1,800 (Integration & Support). Adolescent pathways start at £1,150 and go up to £2,050. Most adults choose Comprehensive (from £1,200), which adds ASD screening, informant input, and a feedback meeting. Final fees depend on the package and any optional add-ons, and are confirmed at triage.

Is a private ADHD assessment legitimate, and will my GP accept it?

We use validated tools and structured clinical assessment led by qualified practitioners. Reports are written to a high standard; many clients share them with their GP. Uptake can vary by practice — we are happy to discuss what to expect when you enquire.

How long does the process take from enquiry to report?

Timing depends on triage, clinician availability, and how quickly questionnaires and informant information come back. We will give you a realistic outline after your enquiry and keep you informed at each stage.

What is the difference between the packages?

All packages include screening, a full clinical interview, and a diagnostic report. Higher packages add depth — such as ASD screening, informant input, psychiatrist review, medication guidance, and follow-up support — depending on what you need. We can help you choose during triage.

Do I need a GP referral?

No. You can self-refer. If you have existing letters or reports that are relevant, you can share them as part of assessment.

What happens after diagnosis — do you prescribe medication?

NDY does not currently prescribe ADHD medication directly. Where medication may be helpful, we have direct links to prescribers and can support you to understand the next steps after assessment. Prescribing and monitoring are managed by the prescribing clinician.

Is ADHD assessment online or in person?

Adult ADHD assessments listed here are delivered online nationwide. If you have access needs or questions about format, mention them when you enquire.

What if I think I might be autistic as well?

ADHD and autism can overlap, so we screen for autistic traits as part of our ADHD assessment process for most packages, even when we are not completing a full autism assessment. If the screening suggests that autism may also be relevant, we can discuss whether a full autism assessment, combined AuDHD assessment, or staged pathway would be helpful.

Locations we serve

Associate clinicians work across the UK. ADHD assessments are often delivered online nationwide; autism pathways may include in-person options depending on location. Explore location guides below — final arrangements are confirmed after triage.
