Why us?

ADHD assessments on the NHS often have very long waiting times. Private ADHD assessments can be produced much more quickly and to a high standard. We deliver a range of strategies to manage ADHD. Medication works best when combined with other strategies. When you have one of our assessments followed by a medication management programme, our psychiatrist can, under a shared care agreement, transfer the care back to your GP to prescribe and continue the medication once the correct dose is identified.

ADHD Assessments by Top Psychologists for Children and Young People

Our ADHD assessments involve a detailed clinical interview with a very experienced Chartered Psychologist and completing the Conners Adult ADHD Rating Scales (Second Edition) or Conners4 (for children) and the Behavioural Inventory of Executive Function. One of the rating forms can be achieved by someone who knows the person being assessed well. Additional rating scales can be provided for £100. Additionally, there is also an assessment of working memory and processing speed. Finally, there are observations of the examinee in the evaluation to see if their behaviour is consistent with someone with ADHD. We also provide free informant forms. We work with you to produce a detailed developmental history.

Following the assessment, the individual receives a comprehensive ADHD report, spanning about 30 pages. This detailed report not only includes recommended reasonable adjustments but also provides very specific strategies that the individual can implement to manage the symptoms of ADHD. The report is designed to equip individuals with the tools they need to treat and manage ADHD without medication.

Our comprehensive, high-quality Attention-Deficit Hyperactivity reports meet the rigorous standards of the Specific Learning Disabilities Assessment Standards Committee and the Joint Council for Qualifications Guidelines and the NHS. As such, they are suitable for use in education and employment. Our reports also meet the required standards of Student Finance England.

The cost of the ADHD assessment and report is £550, which can be conveniently paid in instalments when using PayPal. For those who require an urgent report within seven days, the cost is £1,100. We believe in providing flexible payment options to ensure our services are accessible to all.

Online ADHD assessments, conducted via Zoom or Microsoft Teams, are a convenient and equally valid option. Rest assured, our online assessments maintain the same level of reliability as our face-to-face assessments. If you prefer a face-to-face assessment, there is an additional fee of £200 for the first hour and then £200 per hour for each additional hour.

ADHD Medication

If you require a psychiatrist consultation and medication for ADHD, the cost of each ADHD titration session is £300 per half hour.

What we offer

Cognitive Assessments to Support ADHD Assessments

Many people will benefit from a cognitive assessment as part of an enhanced ADHD assessment. Our cognitive assessments help determine whether the individual has a learning disability and ADHD. With individuals with high IQ scores, the cognitive assessment can also help to identify disparities between intelligence and academic or occupational performance. The cost of a Level 1 cognitive assessment is £475 if the examinee requires a cognitive assessment to be released within four weeks and £950 if the examinee requires the cognitive assessment report within seven days

Coaching, Therapy & Additional Consultation Meetings

We provide ongoing support through coaching, CBT, counselling, and tuition at £100 per 30-minute session. If medication is required, a post-assessment consultation with our psychiatrist is needed to obtain a prescription, charged at £300 per 30-minute session. We recommend informing your GP that you wish to exercise your right to a private ADHD diagnosis. We can also provide a detailed letter to your GP following diagnosis for £100. Additionally, we offer tuition and coaching to support studies and improve executive functioning at £100 per hour.

Support

and Access to Funding

Our reports can be used to support reasonable adjustments in education, including extra time in exams, the Disabled Student Allowance financial grant in higher education and Education and Health Care Plans. Our clients also use our reports for reasonable adjustments in employment and to support applications for Access to Work grants.

What Does our Gold‑Standard Child or Adolescent ADHD Assessment Involve

Unlocking Potential: Why a Rapid, Evidence‑Based Child & Adolescent ADHD Assessment Changes Everything

Attention‑Deficit/Hyperactivity Disorder (ADHD) is one of the most researched neurodevelopmental conditions, yet thousands of UK families still wait years for a diagnosis. The longer the delay, the steeper the developmental, emotional and economic costs. This article explainswhy early identification matters, what a gold‑standard assessment looks like, and how Advanced Assessments Ltd delivers fast, clinically robust answers for children and teenagers. Our aim is to give parents, carers and referrers clear, practical information—grounded in science but written in plain English—while naturally weaving in key search terms such aschild ADHD assessment,teenage ADHD assessmentandprivate ADHD diagnosis UK.

Why Early and Accurate ADHD Assessment Matters

Prevalence and rising demand

Population studies place childhood ADHD prevalence in the UK between 2 % and 5 %(National Institute for Health and Care Excellence [NICE], 2018). Primary‑care data reveal a continued upward trend; by 2018, 3.5 % of boys aged 10–16 years had a confirmed diagnosis, compared with 1.4 % in 2000 (McKechnie et al., 2023). Demand has surged again since the pandemic, with NHS prescriptions for ADHD medication climbing 73 % year‑on‑year to a record 64,664 in February 2025 (Financial Times, 2025).

Untreated ADHD is not a ‘phase’ children outgrow. Long‑term cohort data connect persistent symptoms to lower GCSE grades, strained peer relationships, anxiety disorders, substance misuse and justice‑system involvement (Sayal et al., 2018). TheIndependent ADHD Taskforceestimates that delayed diagnosis and inadequate support cost the UKabout £17 billion every yearin lost productivity, special‑education funding and criminal‑justice expenditure (Independent ADHD Taskforce, 2025).

Developmental Advantage – Neuroplasticity is greatest in the primary‑school years, so behavioural strategies and (where indicated) medication achieve bigger gains (Daley et al., 2018).

Secondary‑Risk Prevention – Prompt support lowers the likelihood of exclusion, self‑medication with substances and later mental‑health crises (Doshi et al., 2012).

Economic Value – Independent modelling suggests every £1 invested in early diagnosis saves about £4downstream in reduced exclusions and safeguarding costs (Independent ADHD Taskforce, 2025).

Medication – This form of threatment is an option that some parents consider for moderate‑to‑severe ADHD (NICE, 2018). Shared‑care protocols allow GPs to prescribe after a period of titration from a child and adolescent psychiartist or clnical pharmactist.

Parent Training Programmes – Meta‑analyses show significant improvements in child behaviour and parental stress (Sonuga‑Barke et al., 2013).

Classroom Accommodations – Simple changes such as seating near the teacher, chunking instructions and movement breaks can halve task‑completion times (Daley et al., 2018).

Cognitive‑Behavioural Therapy (CBT) – Evidence supports CBT for adolescents struggling with time‑management and emotional regulation (Jameson et al., 2022).

Academic and Legal Advantages

A detailed psychological report helps schools meet their duties under the Equality Act 2010, strengthens applications for Education, Health & Care Plans (EHCPs) and provides documentation accepted by examination boards for extra time or supervised rest breaks.

What is included in the assessment

A professional ADHD diagnostic assessment should consider the whole person. At Advanced Assessments Ltd, the assessment pathway may include a structured clinical interview, developmental history, current symptom review, standardised rating scales, behavioural observation, collateral information where available, and consideration of emotional, educational and functional factors.

For adults, assessment may explore work, education, relationships, organisation, time management, emotional regulation, impulsivity, restlessness and daily functioning. For children and adolescents, it may consider attention, activity level, learning, behaviour, peer relationships, family functioning and developmental history.

Standardised rating scales may support the assessment process but do not replace clinical judgement. Where appropriate, information may also be gathered from someone who knows the client well. For adults, this may include a partner, parent, sibling, friend or another person able to comment on day-to-day functioning. For children and adolescents, parent and school information can provide valuable additional insight. Further rating scales or interviews may be recommended where clinically appropriate.
