FAQs
These answers are the same ones published on the clinical service pages. If a pathway is not listed here, its page has the detail.
Getting started
Do I need a GP referral?
Self-referrals welcome. If you have existing letters or reports that are relevant, you can share them as part of assessment.
Is ADHD assessment online or in person?
Adult ADHD assessments listed here are delivered online nationwide. If you have access needs or questions about format, mention them when you enquire.
Is the assessment online or in person?
Some assessment components may be offered in person where clinically appropriate or preferred; others can be completed remotely. We confirm delivery at triage.
Fees
How much does a private ADHD assessment cost?
Our adult ADHD packages start at £900 (Core) and range up to £1,800 (Integration & Support). Adolescent pathways start at £1,150 and go up to £2,050. Comprehensive adds autism screening, informant input, two reports, a feedback meeting and tailored recommendations. Clinical triage will help identify which package best fits the assessment question. Final fees depend on the package and any optional add-ons, and are confirmed at triage.
How much does a private autism assessment cost?
Our adult autism packages start at £1,050 (Core) and range up to £2,650 (Integrated Assessment & Support). Adolescent pathways start at £1,300 and go up to £2,900. Comprehensive includes a full informant interview, complete ADI-R, feedback meeting and dual reporting. Enhanced adds one further specialist assessment or consultation selected according to clinical need. This may be delivered remotely or in person depending on the component required. Final fees are confirmed at triage.
How much does a combined AuDHD assessment cost?
Our adult combined ADHD + autism packages start at £1,800 (Core) and range up to £4,100 (Integrated Assessment & Support). Adolescent pathways start at £2,200 and go up to £4,450. Comprehensive adds fuller informant evidence, complete ADI-R, feedback and dual reporting. Enhanced adds one further specialist assessment or consultation selected according to clinical need. This may be delivered remotely or in person depending on the component required. Final fees are confirmed at triage.
Assessment
Is a private ADHD assessment legitimate, and will my GP accept it?
We use validated tools and structured clinical assessment led by qualified practitioners. Reports are written to a high standard; many clients share them with their GP. Uptake can vary by practice — we are happy to discuss what to expect when you enquire.
How long does the process take from enquiry to report?
Once we have received your written consent and payment (in full or a deposit), we usually complete the assessment, offer feedback and provide your report within 4–8 weeks. This depends on your availability and that of your informants, and on whether any additional information or tests are needed. We keep you informed at every stage.
What is the difference between the packages?
All packages include screening, a full clinical interview, and a diagnostic report. Higher packages add depth — such as ASD screening, informant input, psychiatrist review, medication guidance, and follow-up support — depending on what you need. We can help you choose during triage.
What if I think I might be autistic as well?
ADHD and autism can overlap, so we screen for autistic traits as part of our ADHD assessment process for most packages, even when we are not completing a full autism assessment. If the screening suggests that autism may also be relevant, we can discuss whether a full autism assessment, combined AuDHD assessment, or staged pathway would be helpful.
Is a private autism assessment legitimate, and will my GP accept it?
We follow recognised diagnostic frameworks and use validated tools with qualified practitioners. Reports are written to a high standard; many clients share them with their GP or education provider. Uptake can vary by practice — we are happy to discuss what to expect when you enquire.
Do I need an ADOS-2 to get an autism diagnosis?
Not always. Assessment should be based on a coherent formulation using multiple sources of information. Enhanced adds one further specialist assessment or consultation selected according to clinical need. This may include a structured observational assessment such as ADOS-2. This may be delivered remotely or in person depending on the component required.
What is the difference between Core, Comprehensive, Enhanced, and Multidisciplinary?
Core includes screening, questionnaires, an ADI-R-informed clinical interview, diagnostic evaluation, and a full report. Comprehensive includes a full informant interview, complete ADI-R, feedback meeting and dual reporting. Enhanced adds one further specialist assessment or consultation selected according to clinical need. This may be delivered remotely or in person depending on the component required. Multidisciplinary adds input from two or more relevant clinical disciplines, brought together in an integrated multidisciplinary formulation. Integrated Assessment & Support adds three post-diagnostic support sessions, family involvement where appropriate, and practical support to translate the findings into everyday life.
Will I need a parent, partner, or other informant to take part?
Informant input strengthens developmental history and cross-setting picture, especially for the full ADI-R at Comprehensive and above. We will discuss who is appropriate (for example a parent, partner, or someone who knows you well) and obtain consent. If an informant cannot take part, we will discuss what is still possible.
How long does the whole assessment take, end to end?
Once we have received your written consent and payment (in full or a deposit), we usually complete the assessment, offer feedback and provide your report within 4–8 weeks. This depends on your availability and that of your informants, and on whether any additional information or tests are needed. We keep you informed at every stage.
Can I be assessed for both autism and ADHD?
Yes — many people explore both. We offer a combined ADHD and autism (AuDHD) pathway where that fits your needs; see our combined assessment service or mention it when you enquire.
What happens if you conclude I'm not autistic?
You still receive a clear account of what we observed, what was considered, and practical next steps — which might include support for anxiety or ADHD, signposting, or further assessment. The goal is clarity that helps you move forward.
Should I have a single combined assessment, or assess ADHD and autism separately?
If both are live questions for you, a single joined-up pathway usually gives the clearest picture: one team, one timeline, and explicit attention to overlap. If you only want one condition explored, our standalone ADHD or autism services may fit better — we can discuss at triage.
What if I already have one diagnosis (ADHD or autism) — can I add the other?
Yes. We take a full history and may use existing reports, but we still complete a thorough assessment for the additional profile so conclusions are current and defensible. Tell us what you already have when you enquire.
Is the report one combined document or two separate diagnoses?
You receive a coherent report that addresses both presentations and how they interact. Where criteria are met, conclusions are clearly stated for each; where not, we explain what we did find and what might help next.
How do you tell ADHD apart from autism when symptoms overlap (focus, social, behaviour)?
We do not rely on a single measure. We use developmental history, pattern of difficulties across settings, structured interviews, questionnaires, and (where included) observation — then we weigh alternative explanations. The goal is a formulation that fits you, not a checklist score.
Will an ADOS-2 in person be required for AuDHD?
Not in every package. Enhanced adds one further specialist assessment or consultation selected according to clinical need. This may include a structured observational assessment such as ADOS-2. This may be delivered remotely or in person depending on the component required.
Will the AuDHD pathway take longer than a single-condition assessment?
Once we have received your written consent and payment (in full or a deposit), we usually complete the assessment, offer feedback and provide your report within 4–8 weeks. This depends on your availability and that of your informants, and on whether any additional information or tests are needed. We keep you informed at every stage.
What is the difference between Core, Comprehensive, Enhanced, and Multidisciplinary for AuDHD?
Core includes dual-track screening, combined questionnaires, ADI-R-informed autism interview, ADHD evaluation, and a full diagnostic report. Comprehensive adds fuller informant evidence, complete ADI-R, feedback and dual reporting. Enhanced adds one further specialist assessment or consultation selected according to clinical need. This may be delivered remotely or in person depending on the component required. Multidisciplinary adds input from two or more relevant clinical disciplines, brought together in an integrated multidisciplinary formulation.
What if you conclude I have one of the conditions but not both?
You still receive a clear account of what we observed, what was considered, and practical next steps — including support, signposting, or further assessment if needed. The aim is an honest formulation that helps you move forward.
Treatment
What happens after diagnosis — do you prescribe medication?
ADHD medication initiation and titration may be provided by appropriately qualified prescribers within NDY's clinical governance arrangements. This includes consultant psychiatrists, appropriately qualified pharmacist prescribers and other non-medical prescribers who are trained and competent in ADHD medication initiation and titration. Medical oversight is provided through NDY's medical governance arrangements. Relevant GP and medical information will be required.
Can NDY help with medication after an AuDHD assessment?
ADHD medication initiation and titration may be provided by appropriately qualified prescribers within NDY's clinical governance arrangements. This includes consultant psychiatrists, appropriately qualified pharmacist prescribers and other non-medical prescribers who are trained and competent in ADHD medication initiation and titration. Medical oversight is provided through NDY's medical governance arrangements.
Still not sure where to start?
You do not need to choose a pathway before you enquire. We will help after clinical triage.
