Understanding the Process
What Is a Mental Health Assessment?
A mental health assessment is a structured clinical evaluation conducted by a qualified mental health professional. It is designed to identify whether a diagnosable mental health condition is present, understand the nature and severity of your symptoms, and determine the most appropriate course of treatment.
Unlike a standard GP appointment, which typically lasts 10 minutes and focuses on immediate symptom management, a clinical mental health assessment goes deeper. It draws on your personal history, presenting concerns, and validated screening tools to build a complete clinical picture, resulting in a formal written report that meets NHS and private healthcare standards.
A mental health assessment is not therapy. It is the clinical step that tells you and your healthcare providers exactly what you are dealing with, so that any therapy or treatment that follows is targeted, appropriate, and effective. Your assessment uses the ICD-11 (World Health Organization) and the DSM-5 (American Psychiatric Association), the same frameworks used across NHS and private psychiatric services in the UK.
What happens during your assessment
Your NMC-registered Mental Health Nurse will ask about your current symptoms and how long you have experienced them, how your difficulties affect your daily life, work, and relationships, your personal and family mental health history, and any previous treatment or diagnosis. You will also complete validated clinical screening questionnaires. At the end of the session, your nurse will outline next steps and what to expect from your written report.

Who This Is For
Conditions We Assess and Diagnose - Online, Same Week
You do not need to know what is wrong before you book. Our clinical assessment is designed to identify and formally diagnose the condition driving your symptoms. Where criteria are met, you receive a written diagnosis using ICD-11 / DSM-5 standards.
A formal clinical diagnosis is the primary outcome of your assessment.
Each condition below has a dedicated clinical guide with detailed information on symptoms, diagnostic criteria, and treatment options. Follow the links to learn more and return here when you are ready to book.
Anxiety & Panic Disorder Assessment
Including GAD, panic disorder, social anxiety, and health anxiety. Many people live with significant anxiety for years without a diagnosis, meaning treatment is poorly matched to the specific disorder present.
- Find out more
Depression & Low Mood Assessment
Encompassing major depressive disorder, persistent depressive disorder, and related presentations. Many people seek therapy for low mood without a formal diagnosis calibrated to the severity of their presentation.
- Find out more
PTSD & Trauma Assessment
PTSD and complex PTSD are frequently misdiagnosed as generalised anxiety or depression. The evidence-based treatments for trauma are distinct, and accurate diagnosis is essential before starting treatment.
- Find out more
OCD Assessment
OCD is significantly underdiagnosed, partly because many people experience primarily intrusive thoughts without visible compulsions. The condition covers a wide spectrum including harm OCD, relationship OCD, and pure-O presentations.
- Find out more
Eating Disorder Assessment
Including anorexia nervosa, bulimia nervosa, binge eating disorder, and ARFID. Eating disorders are frequently missed in GP and therapy settings, and early formal diagnosis significantly improves treatment outcomes.
- Find out more
Bipolar Disorder Assessment
One of the most frequently misdiagnosed conditions, often presenting initially as depression. Accurate diagnosis is critical because the treatment pathway for bipolar disorder differs substantially from unipolar depression.
- Find out more
Sleep & Physical Symptom Assessment
Clinically significant sleep disorders and physical symptoms, including chronic fatigue, appetite disruption, and psychosomatic presentations, frequently have a mental health basis that standard physical investigations miss.
- Find out more
Burnout & Work Stress Assessment
Occupational burnout is formally coded under ICD-11 (QD85), a diagnosable and documentable condition. A formal diagnosis carries weight for HR processes, insurance claims, and GP consultations.
- Find out more
Personality & Relationship Pattern Assessment
Including EUPD/BPD and patterns of difficulty with emotional regulation, identity, and attachment. Symptoms frequently overlap with depression, anxiety, and trauma, making formal assessment essential.
- Find out more
Not sure if your experience fits? That is exactly what the assessment is for. If you feel something is wrong, our clinician will work to identify what and give you a clear clinical answer either way.

Why This Step Matters
Why Get a Diagnosis Before Starting Therapy?
Many people begin therapy without first understanding what they are treating. Starting treatment without a diagnosis carries a real risk: you may end up in the wrong therapy for months or years.
The Wrong-Therapy Problem
CBT is widely recommended but not appropriate for every condition. Someone with undiagnosed complex trauma may find it counterproductive. Someone with undiagnosed bipolar disorder may be harmed by antidepressants without mood stabilisation. A formal diagnosis removes the guesswork.
↳ A diagnosis tells you exactly which therapy works for you
The GP Evidence Gap
GPs need clinical documentation to prescribe or refer. Without a formal assessment report, many GPs cannot act, not because they do not believe you, but because they require clinical evidence to justify the decision. An ADHD Certify report gives your GP exactly what they need.
↳ Walk into your GP with evidence, not just your word
The NHS Waiting Time Reality
NHS community mental health services have no set waiting time standard, with many areas reporting 12+ months from referral to first clinical contact. Private psychiatrists cost £400–£800. An ADHD Certify assessment can happen this week for £349.
↳ Same-week assessment — diagnosis in 10 working days
Understanding Your Diagnosis
For many people, a formal diagnosis is the first time their experience has been clinically validated. Knowing that what you feel has a name, a recognised cause, and an evidence-based treatment path gives you something concrete to act on.
↳ Finally understand why you feel the way you do

Questions People Ask Before Booking
Frequently Asked Questions About
Mental Health Assessment
If it is not answered below, call us on 020 8137 3786. We are happy to talk it through before you book.
Will my GP accept this report?
Yes. Your assessment is conducted by an NMC-registered Mental Health Nurse, the same professional standard recognised by the NHS. The report is written in clinical language specifically designed for GP use, covering diagnosis, clinical rationale, and recommendations for medication or further referral. Our Clinical Director Rebecca Wilson (NMC: 13E2851E) is also a qualified Independent Prescriber (V300), meaning our recommendations carry the clinical weight GPs need to act.
How is this different from just starting therapy?
Therapy without diagnosis is like taking medicine without knowing the illness. A diagnostic assessment tells you and your therapist exactly what condition is present and which therapeutic approach is clinically indicated. This means faster results and far less wasted time and money on treatments that are not right for you.
What if the nurse doesn't give me a diagnosis?
Not every assessment results in a diagnosable condition, and that is itself a valuable clinical finding. Your report will still include a thorough summary of your presenting concerns, clinical observations, and clear recommendations for support or monitoring. You will never leave without a concrete next step.
How long does it take to get my report?
Your session lasts 90 minutes. A thorough clinical assessment cannot be done in 20 to 30 minutes, and rushing risks missing important clinical information. Your full Clinical Diagnostic Report and Personalised Treatment Pathway is guaranteed within 10 working days of your session. Most clients receive theirs within 6 to 8 working days.
What if I need medication?
If your assessment indicates medication may be appropriate, your report will include a formal clinical recommendation for your GP. Our Clinical Director Rebecca Wilson is a qualified Independent Prescriber (V300), so our recommendations are written in the clinical language GPs need to prescribe or refer with confidence.
Is my session completely confidential?
Absolutely. All sessions are conducted via encrypted, secure video. Your personal information and clinical report are handled in strict compliance with UK GDPR. Your information is never shared without your explicit consent, except in the rare circumstances required by law, such as immediate risk to life.
Is £349 the full price? Are there hidden fees?
£349 is the complete, all-inclusive price, with no hidden fees and no additional charges for your written report or GP correspondence. Compare this with private psychiatrists who typically charge £350–£800 and may bill separately for written reports and follow-up letters.
Can I use this assessment for workplace or educational support?
Yes. Many clients use their clinical report for workplace reasonable adjustments under the Equality Act 2010, university disability support, or insurance documentation. Reports are written using ICD-11 / DSM-5 criteria and meet the professional standard required by most UK employers, universities, and insurers.
