Adult ADHD Assessment
A structured clinical ADHD assessment for adults: one appointment of around two hours, in person or online. It considers patterns of attention, activity and impulse regulation, and how these are experienced day to day, using evidence-based tools alongside a clinical interview and information from people who know you.
Outcomes are reviewed by a clinical panel chaired by a Clinical Psychologist, informed by the NICE guidelines. We don't prescribe medication; we can explain the routes that do.

Understanding ADHD
About autism
ADHD affects how attention, activity levels and impulse regulation are experienced and managed. It is not simply about being distracted or hyperactive, but reflects differences in how the brain organises and responds to information and demands.
ADHD can present differently from person to person. Some individuals experience more difficulty with attention, such as sustaining focus or keeping organised. Others may notice higher levels of restlessness or impulsive responding. Many people experience a combination of these.
In adulthood, ADHD may look different from earlier years. Physical hyperactivity may become a sense of internal restlessness, while challenges with time management, organisation, and emotional regulation can become more noticeable in daily responsibilities.
Common ADHD Experiences
- Difficulty starting or finishing tasks, particularly those that feel repetitive or less engaging
- Frequently misplacing items such as keys, phones or documents
- Challenges with time management, including running late or underestimating how long things take
- Feeling physically or internally restless
- Interrupting others in conversation without intending to
- Becoming highly focused on areas of interest while struggling to engage with other tasks
- Making decisions quickly without always considering longer-term consequences
- Difficulty following through on plans or commitments
- Feeling overwhelmed by tasks requiring sustained effort or organisation
- Emotional responses that feel strong or difficult to regulate in the moment
- Putting off tasks until they become urgent
What sets us apart
A clear timescale, without reducing clinical depth
First appointment usually within one to two weeks of booking; written report within three weeks of the final session. One appointment of around two hours, with the questionnaires and background gathered beforehand so the time with your clinician goes on what matters.
Multidisciplinary clinical approach
Every outcome is reviewed by a clinical panel chaired by a Clinical Psychologist, informed by the NICE guidelines, so different professional perspectives contribute to a shared clinical understanding.

One clinical appointment
A single structured appointment of around two hours, in person or online, exploring your experiences in depth, including how things are now and how they have been over time.

People we've worked with
Reflections and feedback from adults our clinicians have supported with ADHD.
"I came in thinking ADHD was just about being distracted or impulsive. What I got instead was a much fuller understanding of how it shows up in my day-to-day life. The sessions gave me space to think things through properly, without feeling judged or rushed."
Bradley
"The work helped me see ADHD differently, not just as something that makes things harder, but as something that also shapes how I think and engage with the world. We were able to look at both the challenges and the strengths in a way that actually felt realistic."

Frequently Asked Questions
Common questions about our ADHD assessment service.
ADHD and autism assessments focus on different areas of experience. ADHD assessment looks at patterns of attention, activity and impulse regulation, while autism assessment focuses on areas such as social communication, sensory experiences, and patterns of behaviour. There can be overlap between the two, and some people experience characteristics of both. Where this is relevant, this can be explored as part of the assessment process.
You don't need to have all the answers
It's completely normal to feel uncertain or overwhelmed. Many people reach out to us with questions, concerns, or simply a feeling that something might need support. There's no pressure, just a conversation to help you understand your options and find the right path forward.
