Private ADHD Assessments in London

We provide private ADHD assessments and treatment in London and online with our team of consultant psychiatrists and ADHD specialists. Get fast access to clear diagnosis and structured treatment pathways for adults and children.

What is an ADHD Assessment?

An ADHD assessment is an evidence-based evaluation to determine whether someone meets the diagnostic criteria for Attention Deficit Hyperactivity Disorder (ADHD). Unlike online tests or screening, an ADHD assessment is a detailed clinical analysis carried out in line with NICE guidance.

ADHD presents differently in adults and children. For adults, ADHD symptoms include disorganisation, struggles at work, time management difficulties, overwhelming emotions, and constantly feeling behind despite strong ability. Many people seek ADHD assessments in London later in life.

Symptoms in children may appear as lack of concentration at school, impulsive behaviour, restlessness, or poor academic performance despite potential. Find out more about ADHD symptoms.

Many people are concerned about "overdiagnosis". However, a thorough assessment only results in a positive diagnosis when strict criteria are met. Symptoms must be persistent, cause a significant impairment, and not be explained better by any other conditions.

A private ADHD diagnosis in London involves an extensive clinical interview, validated diagnostic tools, developmental history, and an assessment of the functional impact of symptoms. The main aim of an assessment is clarity. It may lead to a diagnosis, alternative explanations or conditions, or a tailored treatment plan.

Adult & Child Assessments in London

We provide comprehensive ADHD assessments for both adults and children, delivered by experienced clinicians using structured, evidence-based methods aligned with national guidance.

Adult ADHD Assessments

An Adult ADHD assessment London is designed to explore how symptoms may be affecting work, relationships, and day-to-day functioning.

Many adults seek assessment due to:

  • Ongoing workplace performance difficulties
  • Missed deadlines or disorganisation despite strong ability
  • Relationship strain linked to impulsivity or emotional regulation
  • Long-term masking of symptoms leading to burnout

The assessment includes a detailed clinical interview, developmental history, and structured tools such as the DIVA diagnostic interview. If diagnostic criteria are met, a formal diagnostic report is provided, outlining findings and recommendations for treatment or workplace support.

The goal is clarity, whether that leads to diagnosis or alternative guidance.

Child & Adolescent ADHD Assessments

A Child ADHD assessment London focuses on understanding symptoms within the context of development, education, and home life.

We assess:

  • School-based difficulties with attention, behaviour, or focus
  • Developmental history from early childhood
  • Parent consultation and detailed clinical discussion
  • Teacher feedback or school reports where available

Following assessment, families receive a clear outcome and support planning guidance, including recommendations for school adjustments or next steps.

Our approach ensures both adults and children receive a thorough, structured evaluation tailored to their stage of life.

Our ADHD Assessment Process

Our ADHD assessments follow a clear, structured pathway designed to ensure accuracy, transparency, and clinical rigour. Each stage is thorough, unhurried, and aligned with national diagnostic standards.

Step 1 – Initial Consultation

We begin with a detailed initial consultation to understand your concerns, current symptoms, and background. This stage helps determine suitability for full assessment and ensures the process is tailored to you or your child.

Step 2 – Comprehensive Diagnostic Interview

A structured, in-depth clinical interview is conducted using recognised diagnostic tools (such as DIVA for adults). This typically lasts 60-90 minutes, allowing sufficient time to explore symptoms, developmental history, and functional impact.

Step 3 – Collateral Information

Where appropriate, we gather supporting information from parents, partners, or family members. For children and adolescents, school feedback or teacher reports are included to provide a broader view of functioning across settings.

Step 4 – Diagnosis & Written Report

Following the assessment, we provide a clear diagnostic outcome. If ADHD is diagnosed, a comprehensive written report is included. This document outlines clinical findings, diagnostic reasoning, and recommendations. Our reports are suitable for NHS shared care discussions, educational settings, and employer workplace adjustments.

Step 5 – Treatment Planning

If a diagnosis is confirmed, we discuss next steps. This may include medication titration, therapy, coaching, or practical support strategies. If ADHD is not diagnosed, we provide guidance on alternative explanations and appropriate referrals where needed.

Our structured five-step process ensures clarity, credibility, and confidence at every stage.

ADHD Assessment Costs

Clear pricing and honest guidance around NHS recognition are essential when considering a private assessment.
£650
Initial Adult ADHD Assessment
£900
Initial Child ADHD Assessment
Medication Titration Appointments

£245

Monthly
Stable & Optimised Repeat Prescription

£95

Monthly
The initial assessment includes a comprehensive diagnostic interview, structured evaluation, and a formal written report outlining clinical findings and recommendations.

If medication is recommended, titration involves careful monthly review appointments to safely optimise dosage. Once stable, repeat prescriptions are charged at a fixed rate.

While private care involves upfront costs, one of the key advantages of Private ADHD Assessments is significantly shorter waiting times; typically weeks rather than years compared to some NHS pathways. For many individuals and families, this faster access to clarity and support is a decisive factor.

Shared Care Agreements (SCA)

A Shared Care Agreement (SCA) is an arrangement where, after private diagnosis and medication stabilisation, your NHS GP may agree to take over prescribing under NHS funding.

It is important to understand:

  • Shared care is not automatic or guaranteed
  • Acceptance depends on individual GP practice policy
  • Policies may vary in 2026 and beyond

If shared care is declined, medication and follow-up costs remain private. Being transparent about this ensures there are no unexpected financial implications.

Is a Private ADHD Diagnosis Recognised by the NHS?

Yes, a private ADHD diagnosis is recognised by the NHS when it is conducted by:

  • A GMC-registered psychiatrist, or
  • A suitably trained specialist ADHD clinician following national diagnostic standards

A structured assessment, clear diagnostic reasoning, and a formal written report provide the credibility required for NHS discussions, workplace adjustments, and educational support.

For many individuals exploring Private ADHD Assessments, reassurance around NHS recognition is a key concern. When carried out properly, a private diagnosis is valid, evidence-based, and professionally recognised.

Treatment & Ongoing Support

Following diagnosis, we provide a clear, structured pathway forward. Our approach to treatment after Private ADHD Assessments is evidence-based, clinically monitored, and tailored to individual needs.

ADHD Medication Options

Where appropriate, medication may be recommended as part of treatment. This typically includes licensed stimulant or non-stimulant medications prescribed in line with national guidance. Suitability is assessed carefully, with consideration of medical history and co-existing conditions.

Benefits of ADHD Medication

When clinically appropriate, medication can help improve:

  • Attention and concentration
  • Impulse control
  • Emotional regulation
  • Task completion and organisation

Treatment aims to reduce functional impairment, not change personality, and is monitored closely for safety and effectiveness.

Psychological & Behavioural Support

Medication is not the only intervention. Many individuals benefit from psychological or behavioural strategies, including ADHD-informed therapy, coaching, and structured coping techniques. These approaches support long-term skill development alongside medical treatment.

Workplace & School Adjustments

A formal diagnosis following Private ADHD Assessments can support reasonable adjustments in professional and educational settings. This may include workload modifications, structured deadlines, exam accommodations, or environmental adjustments to improve focus and performance.

Ongoing Monitoring & Titration

If medication is prescribed, treatment begins with careful titration to identify the optimal dose. Regular review appointments ensure safety, symptom improvement, and stability. Once optimised, ongoing monitoring continues to maintain effectiveness over time.
