Could ADHD explain some of the difficulties you have experienced for years?
You may be bright, capable and successful, yet find that everyday tasks take far more effort than they seem to for other people. Perhaps you struggle to concentrate, procrastinate, lose things, forget appointments, underestimate how long tasks will take, or find it difficult to finish what you start.
You may feel restless, easily distracted or impulsive. You may struggle with motivation, emotional regulation, frustration or maintaining routines. Sometimes these difficulties have been present since childhood but were never recognised as ADHD.
For many adults, seeking an assessment comes after years of wondering:
“Why do I find things so difficult when I know I am capable of doing them?”
Our Adult ADHD Assessment provides a comprehensive clinical evaluation designed to understand your experiences across childhood and adulthood—not simply whether you identify with a list of ADHD symptoms.
What is ADHD?
Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental condition that can affect attention, organisation, activity levels and impulse control. In adults, ADHD may present predominantly through difficulties with attention, hyperactive-impulsive symptoms, or a combination of both.
Common difficulties include:
- Difficulty sustaining attention
- Procrastination and difficulty getting started
- Poor organisation and time management
- Forgetfulness and frequently losing things
- Difficulty completing tasks
- Distractibility and restlessness
- Interrupting or acting before thinking
- Impulsive decisions or behaviours
- Difficulty managing frustration and emotions
- Inconsistent performance despite having the ability to perform well
Everyone experiences some of these difficulties occasionally. A diagnosis requires a persistent pattern of symptoms beginning during development, causing meaningful impairment and not being better explained by another condition. A comprehensive clinical assessment is therefore essential.
How common is ADHD?
ADHD is not uncommon in adults. NHS England estimated in May 2026 that approximately 2.49 million people in England have ADHD, including people who have not received a formal diagnosis.
ADHD can nevertheless remain unrecognised for many years. It may be overlooked when symptoms are predominantly inattentive, when an individual has developed strong coping strategies, or when difficulties have previously been attributed to anxiety, depression, stress or other factors.
Women and girls have historically been less likely to be recognised, particularly when difficulties are less outwardly visible and involve attention, organisation, internal restlessness or compensatory strategies.
What does an ADHD assessment involve?
1. Pre-assessment questionnaires
Before your appointment, you will complete appropriate ADHD and mental-health questionnaires. These help us understand your current symptoms and functional difficulties and identify areas requiring further exploration.
2. Developmental and collateral information
ADHD is a developmental condition, so understanding your childhood is an important part of the assessment.
Where possible, a parent or older sibling can provide valuable information about childhood behaviour, school experiences, attention, activity levels, impulsivity and organisation.
A partner or close family member can provide additional information about current functioning, including attention, forgetfulness, organisation, time management, impulsivity and emotional regulation.
We understand that not everyone has access to an informant. This does not automatically prevent an assessment. Available information is considered alongside your clinical history and other findings.
3. Comprehensive clinical assessment
Your clinician will explore your developmental history, education, employment, relationships, current functioning and the difficulties you experience.
We also consider other factors that may affect concentration, memory, motivation and behaviour. ADHD symptoms can overlap with anxiety, depression, trauma, autism, sleep difficulties and other mental-health conditions.
Our aim is to understand the whole person, rather than simply identify symptoms on a checklist.
4. QbCheck objective assessment
Where clinically appropriate, we use QbCheck, a computer-based objective assessment providing quantitative information about attention, activity and impulsivity.
QbCheck provides an additional source of information alongside your clinical interview, developmental history and questionnaires.
Importantly, QbCheck is not a standalone diagnostic test. It cannot independently confirm or exclude ADHD. Its results are interpreted within the context of the complete clinical assessment.
5. Feedback and clinical report
Following the assessment, the clinician will explain the findings and how they relate to your experiences.
Where diagnostic criteria are met, we provide a clear explanation of the diagnosis and recommendations for appropriate next steps. Where ADHD is not supported, we aim to explain the findings clearly and identify other factors or conditions that may warrant consideration.
Enhanced ADHD Assessment
When a more detailed assessment may be appropriate
Most people can be assessed through our comprehensive ADHD assessment. However, some presentations are more complex and benefit from additional clinical exploration.
An Enhanced ADHD Assessment may be appropriate where there is significant diagnostic uncertainty, possible co-existing neurodevelopmental or mental-health conditions, a complex developmental history, substantial functional difficulties, or conflicting information from different sources.
For example, an individual may have possible ADHD alongside autism, anxiety, depression, trauma-related difficulties, obsessive-compulsive symptoms or significant emotional regulation difficulties. Symptoms can overlap, making careful assessment important.
An enhanced assessment may also be appropriate where previous assessments have been inconclusive, where there is considerable masking or compensation, or where a more detailed developmental and clinical history is required.
The enhanced pathway builds on the same comprehensive ADHD assessment but allows greater depth and clinical exploration according to the individual’s needs. This may include more detailed collateral history, exploration of differential diagnoses and consideration of co-existing conditions.
The purpose is not simply to perform more tests. It is to develop a clearer understanding of a more complex clinical presentation.
Your assessment journey
01
Prepare
Complete your pre-assessment questionnaires.

We explore childhood development and, where possible, obtain information from a parent, older sibling, partner or another appropriate person.
03
Clinical assessment
We discuss your current difficulties, functioning and wider mental health.
04
Objective assessment
QbCheck may be used where clinically appropriate to provide additional information about attention, activity and impulsivity.
05
Feedback and report

A personalised assessment—not simply a diagnosis
We recognise that seeking an ADHD assessment can be a significant step. Our approach is thorough, respectful and person-centred.
We consider your developmental history, current difficulties, strengths, challenges and wider clinical picture to provide a clear understanding of your presentation.
Whether you require a comprehensive assessment or an enhanced assessment because of greater complexity, our aim is to help you understand your experiences and identify appropriate next steps.
If you have been wondering whether ADHD could explain your experiences, an assessment can be an important first step towards greater understanding.
