Private ADHD Assessment Services
Attention Deficit Hyperactivity Disorder (ADHD) affects each person differently. A private ADHD diagnostic assessment - available online throughout the UK where appropriate, or in-person at one of our clinics in SE England - provides clarity and understanding, allowing you to access the expert support needed for you or your loved one to thrive.

We’re with you every step of the way
What happens in a private ADHD diagnostic assessment?
To provide the most appropriate support, our specialist team needs to understand your own or your child's unique neurodevelopmental profile. Our experienced clinicians conduct thorough ADHD assessments online or in person at our clinics to determine if and to what extent ADHD is playing a role.
step
1
Screening
Our psychology team, led by consultant clinical psychologists, provides a screening process to give initial insights as to whether you or your loved one might have ADHD. If the results indicate ADHD may be present, we'll recommend moving forward with a private ADHD diagnostic assessment.
step
2
Information Gathering
We gather information from multiple perspectives to understand how ADHD symptoms present across different environments. For adults, before we arrange your assessment, we also ask for insights from someone who has known you since childhood because neurodevelopmental conditions like ADHD are with us from birth. For children and adolescents, we collect observations from school, and in some cases, from other settings, where attention, activity levels, and impulse control are important. This comprehensive view helps our clinical team better understand the impact of potential ADHD symptoms in various aspects of life.
step
3
Assessment
Our ADHD diagnostic assessment is carried out by experts in identifying ADHD across different age groups. For children, either a clinical psychologist, paediatrician, or child and adolescent psychiatrist conducts the assessment. Where needed, we triage referrals to determine the most appropriate specialist. During the assessment, the clinician explores your child's strengths, needs, and developmental history, while observing their behaviour and mannerisms. For adults, a clinical psychologist or psychiatrist conducts a thorough clinical interview using the DIVA-2 assessment tool.
This covers how your traits impact your daily life, work, relationships, and childhood experiences. Whether your ADHD assessment is completed online, where appropriate, or in person, our specialists combine all information gathered from the screening, questionnaires, and the clinical interview, evaluating it against DSM-5 diagnostic criteria. We present the outcome after the assessment, along with specific recommendations for support, adjustments, and treatment options where appropriate.
step
4
Diagnostic Report
Working closely together, our team will produce a comprehensive report providing a clear and detailed breakdown of the assessment. The outcome will be straightforward and easy to understand, and the report can be shared with your child’s school to support a positive and informed conversation about the diagnosis. As our assessments are fully NICE compliant, you can be reassured that our diagnostic reports are recognised and accepted by both the NHS and education systems.
step
5
Support
If the assessment indicates ADHD, we'll discuss with you all appropriate support options for you or your child. This includes a range of possibilities such as psychological support and behavioural strategies. Together, we'll help identify the most suitable approach.

What is ADHD and how can an assessment help?
Cherishing unique minds
ADHD is a neurodevelopmental condition that affects how children and adults process attention, activity, and impulse control. For adults, this can impact work performance, relationships, and daily organisation. For children, it can affect learning, social interactions, and behaviour at school and home. When ADHD is identified through professional diagnostic assessment, individuals can access appropriate support and strategies.
For adults, this might include workplace adjustments and tools for managing time and organisation. For children, we can provide guidance for both home and school environments. Our private ADHD assessment helps you to understand your or your child's unique way of thinking and experiencing the world. With professional guidance and support, people with ADHD can move forward with confidence, building on their strengths while developing effective strategies for areas of difficulty.
What are the signs of ADHD?
You may be experiencing…
Although there are many things that ADHD people share, every person’s brain is unique, so ADHD can be experienced in different ways.
Day to day challenges
Day to day challenges
Managing the practical side of everyday life can take real effort for people with ADHD. A child might lose track of their belongings, forget instructions or find routines hard to stick to. While adults may juggle appointments or chores that start to build up quickly. This does not reflect a lack of trying, but daily routines simply take more energy, and the build-up can be overwhelming.
Challenges with focus and attention
Challenges with focus and attention
People with ADHD can hyperfocus, finding it difficult to stop a task and budget their time. For children, this can show up at school. They could feel ‘told off’ more than their peers due to their difficulty in sticking to the rules. As for adults at work, meeting deadlines and juggling tasks take far more effort.
Personal challenges
Personal challenges
ADHD can shape how a person feels about themselves. Children may feel frustrated when things feel harder for them than for their friends, while adults may feel self-doubt. Motivation may be fleeting, making routines and interests harder to sustain. Recognising ADHD is behind this often brings relief and self-compassion.
Challenging behaviours in children
Challenging behaviours in children
For Children with ADHD, following directions and staying settled can be a genuine challenge rather than a choice. Impulsivity can make it hard to listen or sit still amid the demands of school and family. Parents can understandably become frustrated, and children can respond by acting out, creating an unhelpful cycle.

Frequently Asked Questions
We're here to answer your questions
Online ADHD assessments work well for many children, young people, and adults, particularly where:
- the individual can engage in conversation over video
- there is good supporting information from parents, school, or other settings
- the person feels more comfortable being assessed at home
If there are factors suggesting an in‑person assessment would be more helpful, we will discuss this with you so you can make an informed decision.
Having conducted thousands of private ADHD diagnostic assessments, we understand the condition manifests uniquely in each individual. Our evaluation process is designed to identify various presentation styles and coping mechanisms – especially important when assessing females who often develop sophisticated strategies to manage their symptoms. If ADHD isn't diagnosed, our clinical team provides recommendations for appropriate support and can suggest alternative assessments if needed.
We aim to offer assessment appointments within four to six weeks of receiving all pre-assessment information, whether its an online ADHD assessment or in person. The timeline depends on how quickly we receive completed questionnaires from relevant parties (such as family members, schools, or other professionals who know you or your child well).
Online ADHD assessments follow the same clinical process as in‑person assessments and are delivered via secure video consultation.
There is no difference in price. Online appointments can improve access and flexibility, allowing assessments to take place in a familiar environment without the need to travel.
In the vast majority of cases, yes.
Our ADHD assessments are carried out by experienced clinicians using recognised diagnostic standards. Reports are clear, detailed, and clinically robust, and are commonly used across education, healthcare, and workplace settings.
If an organisation has questions, we will support you and, where appropriate, speak directly with them.
In the vast majority of cases, yes.
Employers are looking for clear, clinically sound information about how ADHD may affect someone and what support may help. This depends on the qualityof the assessment and report rather than whether it was carried out online.
Our reports are written to a high clinical standard and are often used to support workplace understanding and reasonable adjustments. If questions arise, we will support you in addressing them.

Everyone's mind processes information differently. Some people are neurodivergent, processing attention and activity in ways that differ from what's typically expected. While these differences can bring challenges, we believe that with understanding, empathy, and expert support, everyone can thrive. Whether you're seeking a private ADHD assessment for yourself or your child, our support teams are here to help guide your journey.
