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 β€” which typically lasts 10 minutes and focuses on immediate symptom management β€” 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 isΒ not therapy. It is the clinical step that tells you β€” and your healthcare providers β€” exactly what you are dealing with, so that any therapy or treatment that follows is targeted, appropriate, and effective. Your assessment uses theΒ ICD-11 (World Health Organization)Β and theΒ DSM-5 (American Psychiatric Association) β€” 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 β€” 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 β€” 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.

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.

PTSD & Trauma Assessment

PTSD and complex PTSD are frequently misdiagnosed as generalised anxiety or depression. The evidence-based treatments for trauma are distinct β€” accurate diagnosis is essential before starting treatment.

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.

Eating Disorder Assessment

Including anorexia nervosa, bulimia nervosa, binge eating disorder, and ARFID. Eating disorders are frequently missed in GP and therapy settings β€” early formal diagnosis significantly improves treatment outcomes.

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.

Sleep & Physical Symptom Assessment

Clinically significant sleep disorders and physical symptoms β€” chronic fatigue, appetite disruption, psychosomatic presentations β€” frequently have a mental health basis that standard physical investigations miss.

Burnout & Work Stress Assessment

Occupational burnout is formally coded under ICD-11 (QD85) β€” a diagnosable and documentable condition. A formal diagnosis carries weight for HR processes, insurance claims, and GP consultations.

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 β€” making formal assessment essential.

Not sure if your experience fits?Β That’s exactly what the assessment is for. If you feel something is wrong, our clinician will work to identify what β€” 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.
πŸ”„

The Wrong-Therapy Problem

CBT is widely recommended β€” 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

πŸ’Š

The GP Evidence Gap

GPs need clinical documentation to prescribe or refer. Without a formal assessment report, many GPs cannot act β€” not because they don’t believe you, but because they require clinical evidence to justify the decision. A Therachange 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 Β£400–£800. A Therachange assessment can happen this week, for Β£349.

↳ Same-week assessment β€” diagnosis in 10 working days

πŸ’‘

Clarity as Its Own Relief

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 is itself transformative.

↳ Finally understand why you feel the way you do

Frequently Asked Questions About

Mental Health Assessment

If it’s not answered below, call us on 020 4530 8480 β€” we’re happy to talk it through before you book.

Yes. Your assessment is conducted by an NMC-registered Mental Health Nurse β€” 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.
Therapy without diagnosis is like taking medicine without knowing the illness. A diagnostic assessment tells you β€” and your therapist β€” 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 aren’t right for you.
Not every assessment results in a diagnosable condition β€” 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.
Your session lasts 90 minutes β€” a thorough clinical assessment cannot be done in 20–30 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 6–8 working days.
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.
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 β€” except in the rare circumstances required by law, such as immediate risk to life.
Β£349 is the complete, all-inclusive price β€” no hidden fees, no additional charges for your written report or GP correspondence. Compare this with private psychiatrists who typically charge Β£350–£800 and may bill separately for written reports and follow-up letters. If you choose to continue with Therachange therapy afterwards, that is a separate decision with no obligation.

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. Learn more about our clinical team β†’
