We use gold-standard assessment tools such as the ADOS-2 (Autism Diagnostic Observation Schedule) and ADI-R (Autism Diagnostic Interview-Revised) for Autism, as well as clinically validated ADHD screening and diagnostic tools.

We offer face-to-face assessments at selected locations across the UK. Please contact us to find your nearest assessment centre.

No, you don’t need a GP referral. As a private service, we accept self-referrals. You’ll complete a booking form with us, and if we need any additional information from your GP, we’ll discuss this with you before making any contact.

Our waiting times vary, but assessments typically begin within four weeks of booking.

• Child assessments take approximately 6 weeks from the first appointment to receiving the written report.

• Adult assessments usually take around one month to complete.

Unfortunately, we do not offer assessments through the Right to Choose system. Many providers on this scheme now have long waiting lists or are not accepting new referrals. If you explore this option, we advise reviewing their assessment pathway to ensure it meets your needs.

Yes, our assessments are widely recognised. Our clinicians regularly work within NHS diagnostic teams and commissioned NHS services. While rare, if any organisation questions an assessment, we are experienced in addressing concerns.

Yes, every assessment involves a healthcare professional with a doctoral-level qualification, typically a clinical psychologist or psychiatrist, in line with NICE guidelines for ADHD and Autism assessments.

The fee for a Child ADHD Assessment is £1,250. This includes a comprehensive assessment pathway, compliant with NICE guidelines, conducted by experienced Clinical Psychologists.

As part of the assessment, we use the QbCheck, an advanced computer-based tool that provides objective data on inattention, impulsivity, and hyperactivity, enhancing the accuracy of diagnosis beyond traditional questionnaire-based measures.

The assessment fee does not include additional evaluations that may be needed in rare cases, such as an intellectual ability assessment or school observation. If further testing is required, we will discuss this with you after the initial assessment.

We assess children from six years old.

This is because the QbCheck we use as part of the assessment compares a child’s results with others of the same age and gender (normative data is available for ages 6–60). Clinically, it is also important to allow attention and impulse control to develop naturally before assessing for ADHD.

No, you can self-refer, and we will discuss with you if any additional information from your child's GP is needed.

The QbCheck is an objective, computer-based test that measures the three core signs of ADHD:

✔ Hyperactivity – Physical movement and restlessness ✔ Impulsivity – Quick or uncontrolled responses ✔ Inattention – Ability to stay focused

During the test, your child will see geometric shapes on the screen and will need to respond by pressing the space bar at specific times.

• Ages 6–11: The task is more visual and engaging for younger children.

• Ages 12–60: A more advanced version is used for older children and adults.

The QbCheck results provide clinically validated data that is used alongside the clinical interview and rating scales to form an accurate diagnosis.

In most cases, yes. Our structured assessment pathway is designed to provide a clear diagnosis of whether or not your child has ADHD.

However, in some cases, we may need additional information before confirming a diagnosis. This could include:

• Additional school reports

• Intellectual ability testing

• Further clinical observations

If this is necessary, we will discuss it with you and ensure that any delays are in your child’s best interest.

No, our assessment is specifically designed to diagnose ADHD.

However, our experienced clinicians are trained in recognising other developmental and mental health conditions. If they notice anything that suggests further assessment is needed (e.g., for Autism, anxiety, or learning difficulties), they will advise you on next steps and signpost you to relevant services.

No, diagnosing Autism requires a separate type of assessment.

If you would like your child to be assessed for both ADHD and Autism, please refer to our combined ADHD & Autism assessment pathway.

Yes, our ADHD assessments are widely recognised. Our clinicians regularly work within NHS diagnostic teams and commissioned NHS services. While rare, if any organisation questions an assessment, we are experienced in addressing concerns.

Our full child autism assessment is £2,275. This includes multiple appointments with experienced clinicians, a comprehensive diagnostic process and a final report suitable for schools and medical use.

We typically assess children aged 3 and over. For younger children, we’ll guide you through whether an autism assessment is suitable at this stage or if early intervention advice is more appropriate.

Yes. The ADOS-2, a key part of the autism assessment, takes place face-to-face at our London clinic. Other parts of the process, such as the parent interview and feedback session, can be completed online.

We can still complete the assessment without a school observation. In these cases, we may request input from a therapist, learning setting or arrange an alternative observation approach.

In most cases, yes. Our structured assessment pathway is designed to provide a clear diagnosis of whether or not your child has autism.

However, in some cases, we may need additional information before confirming a diagnosis.

If this is necessary, we will discuss it with you and ensure that any delays are in your child’s best interest.

No, our assessment is specifically designed to diagnose ADHD.

However, our experienced clinicians are trained in recognising other developmental and mental health conditions.

ADHD requires a different type of assessment. If you believe your child may also have ADHD, please ask us about our Combined ADHD & Autism Assessment pathway.

Our clinicians are trained in recognising more subtle signs of autism, including how masking may impact presentation. We use multiple methods to gather information and take gender and masking into account during interpretation.

Yes, our autism assessments are widely recognised. Our clinicians regularly work within NHS diagnostic teams and commissioned NHS services. While rare, if any organisation questions an assessment, we are experienced in addressing concerns.

Our adult ADHD assessment is priced at £975. It includes a full diagnostic process using trusted, clinically validated tools like QbCheck and DIVA-5. The assessment is conducted by an experienced Consultant Psychiatrist and is compliant with national guidelines for ADHD diagnosis.

We focus exclusively on diagnosis and do not offer therapy or prescribe medication. If treatment is recommended, you can take our report to your GP or we can refer you to one of our medication pathway partners for further evaluation. They may carry out their own checks before deciding on a treatment plan. We can liaise with your chosen provider as needed.

The QbCheck tool we use is validated for individuals aged 6 to 60. If you're over 60, we can explore alternative assessment methods based on your self-report and any additional background information. In some cases, we may recommend an in-person appointment to ensure a reliable outcome.

We strongly recommend that someone who knew you well during childhood — often called an ‘informant’ — is involved in your assessment. This could be a parent, sibling, relative, partner or close friend. Their input helps us understand how your difficulties may have shown up in your early years, which is an essential part of reaching a reliable diagnosis.

We understand this isn’t always possible. If no informant is available, we may be able to use alternative sources, such as school reports or other written evidence. Please let us know as early as possible if you think this might be a concern — we’ll do our best to support you.

In some cases, if we can’t gather enough developmental history, the outcome of the assessment may be delayed or inconclusive.

In most cases, yes. Our assessment process is designed to reach a clear conclusion. Occasionally, more information may be needed and we’ll discuss this with you if a follow-up or additional step is required to ensure a safe and confident diagnosis.

No — our process is specifically designed to assess ADHD. However, our clinicians are trained to recognise other possible concerns. If something else is identified during the process, we’ll let you know and advise on where to seek further support.

An Autism diagnosis requires a separate assessment process. If you would like to explore both, please see our Combined ADHD & Autism Assessment pathway.

Our full Adult Autism Assessment is priced at £1975. It includes a clinical interview, ADOS-2 observational assessment, feedback session, and detailed report. All assessments are carried out by qualified clinicians with extensive experience in autism diagnosis.

Autism and ADHD require different tools and assessment pathways. If you wish to be assessed for both, please see our Combined ADHD & Autism Assessment service.

The Autism Diagnostic Observation Schedule (ADOS-2) is a structured, interactive assessment used globally in the diagnosis of autism. It allows clinicians to observe communication style, social responses and behavioural cues.

Where possible, we encourage including an informant – someone who can offer insight into your early development and personality. This could be a parent, sibling, partner or close friend. If this isn't possible, we’ll discuss alternatives with you such as written records.

Yes, in most cases our assessment process leads to a clear diagnostic conclusion. If additional information is needed to be confident in the outcome, we’ll let you know and may pause the process to gather more evidence.

No. Our tools are designed specifically to assess for autism. However, if something arises during the assessment that suggests another condition, our clinicians will guide you on appropriate next steps.

Our team has experience working with people who have had unclear or incorrect diagnoses in the past. We take time to review your history carefully and can provide a second opinion where appropriate.
