Evidence First, Person Second To None.

Our clinical approach follows NICE guidance on ADHD (NG87) and autism (CG142) assessment in adults — a structured process applying DSM-5-TR criteria, not a shortened checklist. Here is exactly what that looks like in practice, step by step.

Step by step

What a full assessment actually involves.

Free enquiry call

Fifteen minutes to check an assessment is appropriate, explain the process and give you the full cost. No obligation — and if we don't think an assessment is the right next step, we say so.

Standardised questionnaires

Validated measures of your current difficulties and your childhood, completed before your appointment with save-and-return enabled. They structure the interview; no score diagnoses anything on its own.

Informant and developmental history

A short form from someone who knew you as a child — a NICE recommendation, because ADHD and autism begin in childhood. No one available? School reports, old records or a long-term partner's view work; it never prevents assessment.

Structured clinical interview

A detailed conversation with your [[GMC/HCPC-registered]] specialist covering your developmental history, current symptoms, and how they show up across different areas of your life — not a five-minute checklist.

Differential diagnosis

Your clinician actively considers what else could explain the picture — anxiety, depression, trauma, sleep, thyroid, substance use — and whether more than one condition is present. Ruling things out is as important as ruling them in.

Report and follow-up

A full written report within few working days setting out the outcome and the reasoning, then a follow-up discussion to go through it — whatever the result. A GP letter follows, with your consent.

Our Approach

Evidence first, person second to none.

A diagnosis is a clinical judgement made by a qualified person, based on evidence gathered across your whole life — never a questionnaire score or a computer test result. That is why every stage above exists, and why we won’t skip any of them.

Why it matters

A rushed assessment is worse than no assessment.

A diagnosis reached in fifteen minutes on a webcam can be wrong in both directions — missing a genuine condition, or assigning one that isn’t there. Either mistake has real consequences for medication, workplace adjustments, and how someone understands themselves. A thorough assessment must establish every diagnostic criterion with evidence — which is why ours takes [[X minutes]], and why a diagnosis from an inadequate assessment is more likely to be questioned later, including by a GP considering shared care.

Still deciding? A two minute check costs nothing.

ADHD Screener ~2 minutes

Could it be ADHD?

This short screener covers the symptom areas clinicians assess — attention, restlessness and impulsivity — to indicate whether a full assessment may be worthwhile. It is a screening tool, not a diagnosis.

Who is this screening for?

Almost done — where should we send your results?

Enter your details to see your results on screen and receive a copy, along with a short guide on what to do next.

This screener is an educational tool and does not provide a medical diagnosis. Only a qualified clinician can diagnose ADHD following a full clinical assessment. A positive screen does not mean you (or your child) have ADHD, and a negative screen does not rule it out. If you are struggling, please speak to your GP or a mental health professional.
