Your local ADHD assessment options in London
London has some of the longest ADHD assessment waits in the country. Through the standard NHS pathway, waits commonly stretch from two to six years, and in parts of London and the South East they run longer still. NHS Right to Choose can be faster, but across England Integrated Care Boards have introduced funding limits on Right to Choose providers during 2025-2026, and in a number of areas new bookings have slowed or paused. For many Londoners, a private assessment is the realistic way to be seen in weeks rather than years.

Transparent pricing · you stay in controlInside an ADHD assessment in London
Clinics vary in what they include, and the difference is rarely obvious from a price. These are the stages a thorough assessment covers, and the instruments a CQC-registered clinic should be able to name when you ask.
Screening
ASRS v1.1A short, validated self-report questionnaire. The ASRS v1.1 was developed with the World Health Organization. Screening indicates whether a full assessment is likely to be worthwhile. It is self-completed and is not a diagnosis, a triage decision, or a clinical opinion.
Pre-assessment history
Clinics gather developmental history before the appointment — school reports, and where possible an account from a parent, partner or someone who knew you as a child. ADHD and autism are lifelong, so evidence that traits were present in childhood matters to the diagnostic criteria.
Diagnostic interview
DIVA-5 · QbTestThe assessment itself: a structured clinical interview lasting roughly 60–90 minutes, conducted by a psychiatrist or specialist practitioner. DIVA-5 is the standard structured interview for adult ADHD. Some clinics add an objective computerised measure such as QbTest or MOXO, which records attention and movement against a control group.
Report and outcome
NICE NG87A written diagnostic report setting out what was assessed, the outcome against DSM-5 or ICD-11 criteria, and recommendations. NICE guideline NG87 governs ADHD diagnosis and management in the UK, and a report written to it is what a GP will expect to see.
After a diagnosis
Titration · shared careIf medication is recommended, titration is the supervised period — usually several weeks — of adjusting dose and monitoring response, heart rate and blood pressure. Ongoing prescribing often depends on a shared care agreement between the clinic and your GP. Whether a GP enters one is at their discretion and at their ICB’s, and it is never guaranteed. Ask any clinic what happens if your GP declines, before you book.
ThinkBetter is a marketplace, not a clinical service. The assessment is carried out by the independent clinic you choose, and any diagnosis is theirs to make.
