ADHD Assessment in London for Adults, Children and High-Performing Professionals
Private ADHD Assessments at Regal Private Therapy Practice
At Regal Private Therapy Practice, we provide full diagnostic ADHD assessments in London for adults, adolescents and children from our clinic in Marylebone, located within the Harley Street medical district.
Our assessments, reports and recommendations are conducted by experienced, HCPC-registered Clinical Psychologists, who hold doctoral-level qualifications and have extensive experience working within NHS and private mental health services.
We provide gold-standard ADHD assessments using evidence-based diagnostic frameworks and validated clinical tools, offering clarity, understanding and practical recommendations for the next steps in your journey.
Why Many Adults Seek an ADHD Assessment Later in Life
For many people, ADHD is not recognised during childhood. This is particularly common among high-performing professionals, individuals who have developed strong coping strategies, or those whose symptoms were misunderstood or attributed to other difficulties.
Adults who seek an ADHD assessment often describe lifelong experiences such as:
difficulty sustaining focus or concentration
chronic procrastination or overwhelm
challenges with organisation or time management
feeling mentally “switched on” but unable to prioritise tasks
emotional intensity or frustration
periods of burnout despite high capability
Many professionals are highly intelligent, motivated and successful, yet still feel that everyday tasks require far more effort than they should. An ADHD assessment can help bring clarity to these experiences and provide a framework for understanding how your brain works.
ADHD Assessments for Professionals and High-Achieving Individuals
At Regal Private Therapy Practice we frequently work with professionals, entrepreneurs, creatives and executives who suspect they may have ADHD.
Many have built successful careers while navigating challenges with focus, organisation or emotional regulation. Others find that the increasing demands of work and life have made longstanding difficulties more noticeable.
Our clinicians understand the unique pressures faced by high-performing individuals, and our assessments are designed to explore both the challenges and strengths associated with ADHD.
A diagnosis can often provide a powerful sense of understanding and open the door to practical strategies that support productivity, wellbeing and long-term success.
ADHD Assessments for Children and Adolescents
ADHD can also affect children and teenagers in ways that influence learning, attention, behaviour and emotional wellbeing.
Parents often seek an assessment when they notice challenges such as:
difficulty concentrating at school
restlessness or impulsivity
emotional outbursts
struggles with organisation or homework
challenges maintaining friendships
An assessment can help families better understand their child’s needs and identify strategies and support that can help them thrive both academically and socially.
Our ADHD Assessment Process in London
-
Step 1: Free 15-Minute Consultation
Start with a free, no-obligation call with a Clinical Psychologist. We’ll discuss your experiences, what has led you to seek an ADHD assessment, and whether this is the right next step for you or your child. You’ll also learn what the assessment involves and have the opportunity to ask questions.

We may also ask you to complete brief wellbeing questionnaires to assess mood, anxiety, or other factors that may influence attention and concentration.

Your ADHD assessment appointment lasts approximately two hours.
During the clinical interview, your psychologist will explore your developmental history, strengths, challenges and current experiences. This allows us to understand how ADHD symptoms may affect your daily life.

Following your assessment, we offer neuro-affirmative support for adults, adolescents and children.
This may include therapy, practical strategies for managing ADHD symptoms, and support in understanding and harnessing ADHD strengths.

While ADHD presents differently for each person, common signs may include:
Signs You May Benefit From an ADHD Assessment
Difficulty Sustaining Focus
You may find it difficult to maintain attention during meetings, conversations or routine tasks, particularly when the activity is not highly stimulating.
Chronic Procrastination
Tasks may feel overwhelming to begin, even when they are important or time-sensitive.
Emotional Intensity
ADHD can also affect emotional regulation, leading to frustration, impatience or feeling overwhelmed more easily.
Periods of Burnout
High-performing professionals with ADHD often push themselves extremely hard to compensate for attention difficulties, which can lead to cycles of exhaustion or burnout.
Disorganisation and Time Management Challenges
Many adults with ADHD describe difficulty prioritising tasks, keeping track of deadlines or managing multiple responsibilities.
If these experiences resonate with you, an ADHD assessment may help provide clarity and understanding.

What are the different types of ADHD?
You may have heard the term ADD (Attention Deficit Disorder) and wondered how it differs from ADHD. ADD was once used to describe people who showed primarily inattentive symptoms, without the more obvious hyperactive or impulsive behaviours.
Today, the term ADHD is used universally, but clinicians recognise three main subtypes of ADHD.
-
Difficulty focusing, daydreaming, forgetfulness, disorganisation
More common in girls and women, and often overlooked.
-
Restlessness, fidgeting, difficulty waiting, impulsive speech or actions
-
A mix of inattentive and hyperactive/impulsive features
Does ADHD present differently in different people? Types of ADHD explained
While inattention, hyperactivity and impulsivity are the core features, ADHD doesn’t present the same way in everyone. It can look different in adults, children, teenagers and females.
-
In younger children, ADHD often shows through energy and behaviour that feel difficult to manage at school or home. Common features include:
Difficulty sitting still in class or at the dinner table
Trouble following instructions or completing homework
Forgetting school equipment, homework, or everyday tasks
Emotional outbursts or frustration when asked to concentrate
Struggling to wait their turn in games or conversations
With the right support, children can thrive. Early recognition is key.
-
Adolescence brings new academic and social demands, and ADHD symptoms may become more noticeable. Teens may:
Struggle to stay focused on revision or long assignments
Be more impulsive in decision-making, sometimes taking risks
Experience low confidence or self-esteem if they feel “different”
Forget commitments, deadlines, or personal items
Find it difficult to balance independence with organisation
This stage can be particularly stressful for families, but a clear assessment helps everyone understand what’s happening and strategies for support.
-
For adults, ADHD is often less about running around and more about internal restlessness and difficulties with organisation. Adults may notice:
Trouble with time management, planning, and meeting deadlines
Forgetting appointments or losing important belongings
Feeling mentally “busy” or unable to switch off
Procrastination followed by last-minute surges of productivity
Challenges in relationships, careers, or daily responsibilities
May be sensitive to perceived rejection
Impulsivity may come in the form of excessive spending, binge eating, quitting job if frustrated without back up plan, alcohol or drug use (self medication)
Recognising ADHD in adulthood can be life-changing, offering understanding and practical strategies for success.
-
ADHD in females has historically been under-recognised, as girls and women often show fewer outward signs of hyperactivity. Instead, they may:
Appear “day-dreamy,” or easily distracted
Work extra hard to mask difficulties, leading to exhaustion
Experience perfectionism, anxiety, or overwhelm
Struggle with organisation while feeling highly self-critical
Burn out from managing invisible ADHD challenges
Many women do not receive a diagnosis until adulthood or only suspect ADHD in themselves after their child has been diagnosed with ADHD. Our assessments are tailored to spot these more subtle presentations, ensuring no one is overlooked.
At Regal Private Therapy Practice, our HCPC-registered Clinical Psychologists are highly skilled in recognising nuanced presentations or more subtle signs of ADHD particularly in high masking individuals, ensuring that nothing is overlooked during assessment.
