Demand for ADHD assessment and diagnosis has grown significantly across the UK, particularly among adults who may have lived for years without recognising the condition. At the same time, lengthy waiting lists for specialist NHS services have led more people to consider a private ADHD assessment in the UK or explore NHS-funded services delivered by independent providers through Right to Choose.
NHS waiting times for ADHD assessments remain a major challenge in parts of England. In September 2026, The Guardian reported that several NHS integrated care boards had introduced minimum waits of up to two years for ADHD and autism assessments, amid rising demand and funding pressures. The report said around 960,000 people in England were waiting for an ADHD assessment, highlighting why some patients are exploring private assessment or alternative NHS-funded routes. Patients in England may also be able to access an independent provider through the NHS Right to Choose pathway, although availability and waiting times can vary by area.
For those considering private ADHD assessment, the choice of provider can feel overwhelming. The best private ADHD assessment provider will ultimately depend on factors including age, location, clinician preference, whether you want an online or face-to-face consultation and whether you may require medication or longer-term support after diagnosis.
What should you look for in a private ADHD assessment?
An ADHD assessment should go considerably further than completing an online questionnaire. NHS guidance states that assessment is undertaken by an ADHD specialist and considers the history of symptoms, childhood experiences, education or work, relationships, medical history and, where appropriate, information from someone who knows the individual well.
When comparing providers, look closely at who conducts the assessment, the depth of the diagnostic process, whether a written report is provided and what happens if ADHD is diagnosed. Patients interested in medication should also understand the provider’s titration and follow-up arrangements and discuss potential shared-care prescribing with their GP rather than assuming this will automatically be accepted.
Here are ten established UK ADHD assessment providers to consider in 2026. Services, pricing, availability and suitability vary, so patients should review each provider carefully before making a decision.
Important Note: The list is presented in no particular order and does not represent a ranking or endorsement of one provider over another.
1. ADHD 360
ADHD 360 is one of the UK’s larger specialist ADHD providers, offering services for adults, young adults, children and teenagers. Its pathway starts with online screening before progressing to a video assessment with an ADHD clinician. For patients who receive a diagnosis, the service can extend into medication optimisation, follow-up care, counselling, coaching and peer support. ADHD 360 operates UK-wide and also provides services through NHS pathways.
2. Private ADHD
Private ADHD provides private assessments for both adults and children, with consultations available remotely across the UK as well as in London. Its assessment process combines a detailed clinical interview, developmental history and recognised diagnostic tools, followed by a formal written report. One of the clinic’s strengths from a patient perspective is transparent published pricing for assessment, medication titration and ongoing prescribing.
3. Berkeley Psychiatrists
Based on Harley Street in London, Berkeley Psychiatrists provides both virtual and face-to-face ADHD assessments alongside a wider range of psychiatric and neurodevelopmental services. The clinic has an extensive multidisciplinary team that includes consultant psychiatrists and specialist ADHD clinicians. It also offers ADHD services through NHS Right to Choose and states that its assessments follow NICE guidance.
4. Clinical Partners
Clinical Partners is a major UK mental health provider offering private ADHD assessments for adults and children, both online and in person. Adult assessments include pre-assessment questionnaires, a diagnostic interview incorporating DIVA-5 and a personalised written report. Clinical Partners is also an NHS and CQC-registered provider and delivers ADHD services through Right to Choose, making it particularly relevant for patients comparing private and NHS-funded pathways.
5. Adult ADHD Clinic
Adult ADHD Clinic is a specialist service focused specifically on ADHD in adults and led by consultant neuropsychiatrist Dr Sally Cubbin, a founding member of the UK Adult ADHD Network. Its comprehensive assessments can include treatment recommendations, a detailed report and, where clinically appropriate, medication planning. However, the clinic currently states that it is closed to new referrals due to high demand, so prospective patients should check for updates before considering this option.
6. The ADHD Centre
Established in 2009, The ADHD Centre provides assessments for adults, students and children, with online appointments available alongside clinics in London and Manchester. Assessments are consultant psychiatrist-led, with adult consultations typically lasting 60–90 minutes. The service also provides medication management, coaching, therapy and other forms of post-diagnostic support.
7. Onebright
Onebright offers an online ADHD pathway specifically for adults aged 18 and over. Initial screening is carried out through its neurodevelopmental service before patients considered appropriate for a diagnostic assessment are referred to Psicon, another company within the Onebright group. Assessments are undertaken by a clinical psychologist or psychiatrist, followed by a diagnostic report and discussion of treatment and support options.
8. Psicon
Psicon specialises in neurodevelopmental assessment and provides private ADHD services for both adults and children. Online assessments are available across the UK where clinically appropriate, alongside face-to-face services in Kent and Hampshire. Psicon also works with the NHS and offers Right to Choose services, with assessment, treatment and post-diagnostic support forming part of its wider neurodevelopmental offering.
9. CARE ADHD
CARE ADHD provides ADHD assessment, diagnosis and treatment across the UK for private patients, alongside Right to Choose services in England. The organisation is CQC-regulated and consultant psychiatrist-led, supported by a multidisciplinary team of ADHD clinicians. It now also operates a dedicated under-18 service, broadening its offering beyond adult ADHD care.
10. ADHD Clinical UK
ADHD Clinical UK is a CQC regulated UK-based service providing structured, doctor-led ADHD assessments for adults and children. Assessments consider developmental history, the impact of symptoms on daily life and other possible explanations for a patient’s difficulties, rather than relying on a simple checklist approach. Care is delivered by experienced UK clinicians with a broader medical understanding, with separate age-appropriate pathways for adults and for children.
ADHD UK: An independent resource for patients
Although ADHD UK is not an assessment clinic, it is a useful independent resource for anyone researching an ADHD diagnosis in the UK. The charity provides information about adult and child diagnosis pathways, Right to Choose, NHS waiting times, workplace support and an adult ADHD screener. The NHS itself links patients to ADHD UK for additional information about adult diagnosis pathways.
Choosing the best private ADHD assessment provider in the UK
There is no single clinic that will be right for every patient. Someone looking for a rapid online adult assessment may have different priorities from a parent seeking a child ADHD assessment, while another patient may be particularly concerned about medication, ongoing treatment or interaction with their NHS GP.
Before booking, check exactly who will perform the assessment, what the assessment includes, whether you will receive a comprehensive diagnostic report and what support is available afterwards. If future NHS prescribing is important to you, speak to your GP about shared care before committing to a private pathway.
A private ADHD diagnosis can provide valuable clarity, but choosing the right provider should involve more than simply looking for the quickest appointment. Clinical expertise, the quality of the assessment and continuity of care after diagnosis are equally important considerations.
