ADHD Assessment and Therapy London

Gold-standard QbCheck assessment, expert diagnosis and whole-person ADHD support — without NHS waiting times

ADHD (Attention Deficit Hyperactivity Disorder) is a neurodevelopmental condition affecting how the brain manages attention, impulse control, emotional regulation, and executive function. It affects children, teenagers, and adults — and it remains significantly under-diagnosed, particularly in women, in adults who masked their difficulties throughout childhood, and in highly intelligent individuals whose abilities compensated for their challenges until the demands of adult life made compensation no longer sustainable.

At London Trusted Therapy Harley Street, our ADHD Complete programme provides everything you need in one joined-up pathway: a thorough private ADHD assessment using gold-standard QbCheck technology, a formal diagnosis where appropriate, expert ADHD therapy, specialist psychiatric support and medication management, and evidence-based ADHD coaching. No GP referral is required. No fragmented care across multiple providers. One integrated team, one coherent programme, built around you.

Our ADHD Assessment — What to Expect

A thorough, compassionate private assessment

Our private ADHD assessment in London is conducted at our Harley Street clinic or online, by a multidisciplinary team that includes consultant psychiatrists, clinical psychologists, and HCPC registered psychotherapists — all with specific expertise in adult and childhood ADHD. Appointments are available within days, not months, and the assessment process is designed to feel more like a conversation than a clinical interrogation.

The assessment begins with a detailed clinical interview covering your personal history, developmental background, education, and the way ADHD presents in your day-to-day life. We take time to understand the whole picture — not just whether the diagnostic criteria are met, but how ADHD has shaped your experience, your relationships, your work, and your sense of yourself.

QbCheck — objective, technology-assisted ADHD assessment

A distinctive feature of our ADHD assessment is the use of QbCheck, an FDA-cleared and CE-marked objective measurement tool that provides quantitative data on attention, impulsivity, and activity levels during the assessment process. QbCheck adds an objective, technology-assisted dimension to the clinical interview and standardised rating scales, producing a visual report that is highly useful both for diagnostic purposes and for monitoring the impact of any subsequent treatment.

QbCheck is not a standalone diagnostic tool — it is one component of a rigorous, multi-method assessment. Its value lies in providing measurable, reproducible data that complements clinical judgement and strengthens the evidence base of your assessment report.

Assessment for adults, teenagers and children

Our team assesses for ADHD across the lifespan. For adults, the assessment considers how ADHD presents in the context of work, relationships, emotional regulation, and identity — including late-diagnosed adults who have spent years not understanding why certain things are disproportionately difficult.

For teenagers and children, the assessment incorporates parent and teacher perspectives alongside direct evaluation, providing a holistic understanding of how ADHD is affecting learning, social development, and wellbeing at school and at home.

Our ADHD Team

Our ADHD specialists at London Trusted Therapy Harley Street are fully accredited experts in assessing, diagnosing, and supporting individuals with ADHD across the lifespan. They provide neurodiversity-affirming care in a judgment-free space where your experiences are validated and your strengths recognised. Here are our ADHD specialists — please review their profiles to find the right fit for your needs.

Our Comprehensive Assessment Process

Our thorough ADHD assessment integrates multiple evaluation methods to ensure accurate diagnosis.

NICE-compliant ADHD diagnosis: what this means for you

Our ADHD assessments follow NICE guidelines (the National Institute for Health and Care Excellence) and use DSM-5 diagnostic criteria to ensure your diagnosis is rigorous, recognised, and accepted by GPs, employers, and educational institutions. We use validated screening tools, comprehensive clinical interviews, and objective computerised testing (QbCheck) to ensure nothing is missed.

This means your assessment report carries the clinical weight needed to access medication, workplace adjustments, and ongoing NHS support.

We begin with comprehensive clinical interviews

They explore your developmental history, current symptoms, and functional impairment across different life domains.

ADHD is a lifelong condition with childhood onset, so understanding your early years helps establish whether
symptoms were present before age twelve, as required for diagnosis.

QbCheck objective testing forms a crucial component of our assessment

During this computerised test, you perform a continuous performance task while the system tracks your movements and measures your attention, activity level, and impulse control.

The test generates objective data comparing your performance to age-matched normative databases, identifying patterns consistent with ADHD. Because QbCheck measures actual behavior rather than relying solely on subjective reporting, it significantly reduces assessment bias and increases diagnostic accuracy.

We administer validated diagnostic questionnaires and rating scales

They include both self-report measures and, when possible, collateral information from family members, partners, or close friends who can provide external perspective on your symptoms. We review your medical history, as various medical conditions can mimic or coexist with ADHD.

We assess for common comorbid conditions including anxiety disorders, depression, learning disabilities, autism spectrum disorder, and substance use, as these frequently occur alongside ADHD and influence treatment planning.

Cognitive testing and executive function assessment

Cognitive testing may be included where appropriate to explore specific aspects of executive functioning, working memory, processing speed and attention.

While there’s no single cognitive test that diagnoses ADHD, patterns of cognitive strengths and weaknesses can support diagnostic formulation and inform interventions.

Diagnostic report and explanation of findings

Following assessment, we provide a detailed diagnostic report explaining our findings, confirming or ruling out ADHD diagnosis, describing your specific ADHD presentation, identifying comorbid conditions, discussing functional impact, and recommending treatment approaches.

We carefully explain results in language you can understand, ensuring you leave with clear understanding of your diagnosis and what it means for you.

Combined ADHD and Autism Assessment

Do ADHD and Autism Co-occur?

Research shows that ADHD and autism frequently co-occur, with studies suggesting that 30–80% of autistic individuals also meet criteria for ADHD. If you suspect you may have both conditions, our combined ADHD and autism assessment provides a comprehensive evaluation using gold-standard diagnostic tools including QbCheck for ADHD and ADOS-2 for autism.

How Our Combined Assessment Works

A combined assessment avoids the need for separate appointments and ensures that overlapping or masking symptoms are properly identified. Our clinicians have particular expertise in recognising how these two conditions interact and influence each other.

After Your Assessment — The ADHD Complete Pathway

A diagnosis is the beginning, not the end. Our ADHD Complete programme provides a clear, individually tailored pathway of support following assessment — combining the specialist services most likely to make a meaningful difference for you.

GP Shared Care Agreement for ADHD Medication

We know that the cost of ongoing private prescriptions is a real concern. That’s why we support shared care agreements with your GP wherever possible. Once your ADHD medication is stabilised by your psychiatrist, we provide your GP with a comprehensive report and treatment plan, making it straightforward for them to take over prescribing through the NHS. We’re happy to liaise directly with your GP practice to facilitate this transition and ensure continuity of care.

Regular review appointments allow us to track your progress, adjust strategies, troubleshoot emerging difficulties, and ensure your treatment remains effective as circumstances change. ADHD is a chronic condition requiring ongoing management, and we provide the consistent support you need to thrive long-term.

Psychiatric Partnership and Medication Management

For clients who would benefit from medication as part of their ADHD management, we work in close collaboration with Dr Dmitri Popelyuk of Popelyuk Adult Psychiatry — one of London’s leading consultant psychiatrists in adult ADHD. The working relationship between our therapeutic team and our psychiatric partner is genuinely integrated: your therapist and psychiatrist communicate directly, coordinate your care, and work together to ensure your treatment is holistic and consistent rather than fragmented across providers. Clients consistently identify this integrated model as one of the most significant differences between their experience at London Trusted Therapy and care received elsewhere.

Evidence-Based Therapy for ADHD

Why Therapy Matters

Therapeutic support forms a cornerstone of our ADHD Complete programme. While medication can be highly effective for core ADHD symptoms, therapy addresses the psychological, emotional, and functional impacts of living with ADHD. Many people with ADHD have experienced years of frustration, failure, and criticism, leading to low self-esteem, anxiety, depression, or shame. Therapy helps you process these experiences, develop healthier self-perception, and build psychological resilience.

Emotional Regulation and Mindfulness

We address emotional regulation difficulties that frequently accompany ADHD. Many people with ADHD experience intense emotions that feel overwhelming and difficult to manage. We teach emotion regulation skills, mindfulness techniques for present-moment awareness, strategies for managing frustration and anger, and approaches for handling rejection sensitivity. Learning to recognize, tolerate, and respond skillfully to emotions significantly improves daily functioning and relationships.

ADHD and Co-occurring Conditions

Therapy also addresses comorbid mental health conditions. Anxiety and depression frequently occur alongside ADHD, sometimes as direct consequences of ADHD struggles, other times as independent conditions requiring specific treatment. We provide integrated care addressing both ADHD and coexisting conditions, recognizing how they influence each other.

CBT for ADHD

We utilize evidence-based approaches proven effective for ADHD. Cognitive Behavioral Therapy (CBT) for ADHD helps you identify and challenge unhelpful thought patterns that contribute to procrastination, avoidance, or negative self-talk. You'll learn cognitive strategies for managing ADHD challenges, develop problem-solving skills, address perfectionism or fear of failure, and build self-efficacy and confidence.

Practical Coaching: Building Real-World Skills

Beyond therapeutic support, our ADHD Complete programme includes practical coaching focused on developing concrete strategies and skills for managing ADHD in daily life. ADHD coaching is action-oriented, present-focused, and goal-directed, helping you build systems and structures that support your success.

Executive function skills coaching

helps you develop organisational systems that work with your ADHD brain rather than against it. We help you create sustainable filing systems, email management strategies, paperwork handling approaches, and household organisation methods.

Rather than imposing generic organisational systems, we help you discover what actually works for your specific brain, lifestyle, and challenges.

Time management coaching

addresses the time blindness and poor time perception common in ADHD. You’ll learn strategies for estimating time more accurately, using timers and alarms effectively, breaking large tasks into manageable chunks, building in buffer time, and managing chronic lateness.

We help you develop planning and scheduling skills that account for ADHD challenges rather than fighting against them.

Task initiation and completion

present major difficulties for many people with ADHD. We teach strategies for overcoming procrastination, getting started on difficult tasks, maintaining momentum, managing perfectionism that prevents completion, and following through consistently.

You’ll learn about the role of interest and urgency in ADHD attention, helping you understand why some tasks feel impossible while others are effortlessly engaging.

Priority management

helps you distinguish between urgent and important tasks, make decisions about what truly matters, say no without guilt, and allocate your limited attention and energy strategically.

Many people with ADHD struggle with over-commitment and difficulty prioritising, leading to constant overwhelm.

Workplace accommodations and career support

We provide guidance on workplace accommodations and strategies, helping you understand your rights under disability law, request appropriate accommodations, develop systems that work in your specific job, manage workplace challenges, and advocate for yourself effectively.

Career coaching helps you identify careers and roles that align with ADHD strengths rather than constantly highlighting weaknesses.

ADHD assessment report for workplace adjustments

Your ADHD assessment report isn’t just a diagnosis on paper – it’s a practical tool. Our comprehensive reports are written to support applications for workplace adjustments and reasonable accommodations under the Equality Act 2010, Access to Work funding, and Disabled Students’ Allowance (DSA).

We also offer specialist coaching to help you navigate conversations with your employer about your ADHD, develop strategies for managing your workload, and advocate for the adjustments you need to perform at your best.

Relationship and communication skills coaching

This type of coaching addresses how ADHD impacts interpersonal relationships. ADHD can strain relationships through forgetfulness, inconsistency, emotional reactivity, or apparent lack of interest when actually you’re struggling with attention.

We help you explain ADHD to family and friends, develop strategies for meeting relationship commitments, communicate about ADHD-related challenges, and repair ruptures caused by ADHD symptoms.

Why Choose London Trusted Therapy for Your ADHD Assessment?

If you suspect you might have ADHD, or if you have struggled for years without proper support, seeking assessment is a wise, brave decision.

Diagnosis opens doors to effective treatment, accommodations, self-understanding, and connection with others who share similar experiences.

Our approach to ADHD is shaped by two things that are difficult to find in combination elsewhere. The first is clinical rigour: HCPC registered and BPS accredited professionals, gold-standard QbCheck technology, evidence-based assessment methodology, and integrated psychiatric partnership. The second is lived understanding: several members of our team are themselves neurodivergent and bring a depth of personal insight to their clinical work that transforms the quality of the therapeutic relationship.

Our ADHD Complete programme provides everything you need: objective, thorough assessment using the most advanced technology available; clear diagnosis and comprehensive evaluation; ongoing treatment support coordinating all aspects of your care; evidence-based therapy addressing psychological and emotional impacts; and practical coaching building real-world skills for success.

ADHD is real, it’s treatable, and with proper support, you can absolutely thrive.

Frequently Asked Questions — Private ADHD Assessment London

How soon can I start the assessment process?

We understand that once you decide to seek answers, waiting can be the hardest part. At London Trusted Therapy, we aim to begin your ADHD assessment within days of your initial enquiry. Our streamlined process ensures you move from the first consultation to a definitive diagnosis and treatment plan without unnecessary delays.

What makes the ADHD Complete programme different from a standard assessment?

A standard assessment often ends with a diagnosis, leaving you to navigate the next steps alone. ADHD Complete is a holistic, long-term support system. It integrates objective QbCheck data, clinical expertise, and immediate access to a multimodal treatment plan, including specialised coaching and therapy, all managed by our expert team.

Is the diagnosis from London Trusted Therapy recognised by other providers?

Yes. Our assessments are conducted by highly qualified practitioners following the gold-standard NICE guidelines. Your comprehensive diagnostic report is a formal clinical document that can be used to access medication, request reasonable adjustments in the workplace, or provide evidence for educational support.

Can I transition to medication support after my assessment?

Absolutely. If your diagnosis is confirmed and you choose to explore medication, our clinical team will guide you through the process. We focus on a safe, monitored titration period to ensure the treatment is effective and tailored to your specific needs, always as part of a broader support programme.

What if I already have a diagnosis from elsewhere?

We often welcome clients who have a diagnosis but lack a clear management plan. You can join the ADHD Complete programme to access our specialised therapy and coaching streams, helping you turn your diagnosis into a practical roadmap for daily success at London Trusted Therapy.

Do I need a GP referral for a private ADHD assessment?

No. A GP referral is not required to access a private ADHD assessment at London Trusted Therapy. You can contact us directly to book your initial consultation, and appointments are typically available within days.

How long does a private ADHD assessment take?

A full ADHD assessment typically takes between two and three hours and involves a structured clinical interview, standardised rating scales, and QbCheck objective measurement. A written report is provided following the assessment, typically within two to three weeks.

Can adults be diagnosed with ADHD for the first time?

Yes. Many adults receive their first ADHD diagnosis in their thirties, forties, fifties, and beyond — particularly women, who are consistently under-diagnosed during childhood, and individuals who were highly able academically and compensated for ADHD traits until adult demands made compensation unsustainable. A late diagnosis is equally valid and can be profoundly life-changing.

Does ADHD assessment include a medication review?

The assessment itself focuses on establishing a diagnosis. Where medication is clinically appropriate and desired, we facilitate a referral to our psychiatric partner Dr Popelyuk, who conducts a thorough psychiatric evaluation before prescribing. Our integrated model means your therapist and psychiatrist work collaboratively throughout this process.

What is QbCheck and why does it matter?

QbCheck is an FDA-cleared, objective measurement tool that measures attention, impulsivity, and activity levels during a structured task. It provides quantitative data that complements the clinical interview and standardised questionnaires in our assessment process, adding an evidence-based objective dimension that strengthens the assessment report and provides a baseline for monitoring treatment progress.

Can you assess children and teenagers as well as adults?

Yes. Our team assesses for ADHD across all age groups — children, teenagers, and adults. For younger clients, assessment incorporates parent and teacher information alongside direct evaluation, and our support programmes are tailored to the specific needs of each age group.

Is your ADHD assessment available online?

Yes. Both the initial consultation and elements of the assessment process are available online for clients who are unable to attend our Harley Street clinic in person. Please mention your preference when booking and we will advise on the most appropriate format for your assessment.

How does ADHD Complete differ from a standard ADHD assessment?

Most private ADHD providers offer assessment and, separately, medication management. ADHD Complete is a genuinely integrated programme — assessment, psychiatric partnership, therapy, and specialist coaching available within a single, coordinated team. Your practitioners communicate with each other, your care is coherent rather than fragmented, and you are supported across every dimension of the ADHD experience rather than just at the point of diagnosis.
